I would like to install a device >that will connect directly to our hub (not server) and can be shared. We use NETower, a tower case with 7 4X CD-ROMs in it. You can buy one with only 4 CD-ROMs in it, but you always need more. It comes network-ready, just specify 10BaseT or 10Base2 when you order. (Can also get it for token ring). It came with its own cable. I just plugged it in to a T-connector, ran a very simple Windows-based install program on a workstation where I was logged in as supervisor, then loaded the NLM at the console. (It did require that I have CLIB.NLM ver 3.12f or higher, which I didn't, but they provided it with the install disks). Each time I add a new CD-ROM, I do a few simple steps to make it available to the network: - Insert it in 1 of the bays. - Run the Windows utility, which will automatically discover the new CD and display an icon for it. - Select the icon, then run "configure"--takes about a minute. - Then run "mount"--takes less than a minute. The CD-ROM is now available to be mapped. If a user goes to file manager in Windows and selects "disk" and "network connections", the CD-ROM will be listed there along with the SYS: volume and any other volumes that are mounted. (Assuming you give him rights to the CD during the configure process). You can tell it during configure to automatically mount the CD each time it's inserted in a bay. I do that, so after the initial configure and mount, I can remove and insert CDs and it automatically makes them available. This tower doesn't have to be anywhere near the server. You can give them the administrator utility so they can install new CDs. You can have up to 9 NETowers per server, for a total of 63 CD-ROM volumes. Just remember that mounting a CD is like mounting another hard drive--it uses RAM on the server.

I would like to install a device that >will connect directly to our hub (not server) and can be shared by users. Following up on my previous post. I received many messages on this topic and almost everyone suggested Microtest DiscPort.

We are running Novell 3.11 >and 3.12 and will soon be going over to all 3.12 with a thin-net >back-bone running UTP to all nodes. I recommend Microtest Discport if you're not doing dozens of CD's. I like it because (A) it works; and (B) it requires no TSR's to operate (you load a couple of NLM's which redirect CD access to the DiscPort box.) CD's look just like NW volumes; unless you load a small but friendly TSR, in which case they look like MSCDEX-supported CDROM devices when mapped. ------------------------------ Check out the Oct 23 issue of LAN TIMES, Vol. 12 Issue 22 where they did a review of CD-ROM servers. Past issues can be found at http://www.wcmh.com/lantimes/index.html but they are a bit behind. Bryan Johnson --------- Check out Lan Times October 23 (Vol12, Issue 22) if you can for a comparison of products. They give the "award" to CD-Manager 2.0, but Microtest "Discview Pro 4.01" comes close behind. Although I do not have personal experience with it, I'd probably go with the Microtest product because it appears to blend in better with Netware 4.x plus I've heard some good comments about it.

Does anyone know which patches? ------------- ...why try the square peg in round hole approach? I use and recommend an external tiny box for CD-ROMs. Mine is Discport (c as in UK) made by Microtest. The server runs the supporting NLMs and thinks the external box on the net is a funny local drive (but without the memory consumed by a drive). Users see a new volume, and can talk to the tiny box via the server and its supporting utils (DOS and Windows). Costs about US$600 or so (I've forgotten the current price); it works well, really. ...I don't think many here will believe the USAF is out of money. Delaying one engine start by 30 sec on one aircraft will more than pay for the tiny box...

Not as much load as you might think. We have a 3.12 server (DX2-66, 48MB RAM, 2 GB drives, Adaptec EISA SCSI cards, 100 user, ~ 60% free cache buffers) which has 35 CD-ROM drives running under SCSI Express 1.4.5. CPU usage hovers around 5-15% most days, sometimes less, sometimes more for brief periods of time. We started this server with 16MB of RAM and 14 CD-ROM drives for 50 users and it worked fine, though the free cache buffers were a little on the low side. The combination seems robust and performs quite well. ------------------------------ Date: Wed, 20 Dec 1995 06:19:54 -0600 From: Joe Doupnik Subject: Re: CDROM in Netware 3.12 >I need a little help to networking a CD in a Netware 3.12 LAN.

Do they actually take up 524 MB? Use NDIR, not DIR; they're stored as sparse files and, for most CDs, are significatly less than the 8 MB they claim. Yes, you can delete them, though you will have to endure the delay while the server recreates them for any CDs you remount in future.

The server generally has much more cache than a stand-alone computer, so more of the CD will reside in the cache. Additionally, the entire directory structure is moved to a file on the Netware server when the CD is mounted. ------------------------------ Date: Fri, 19 Jan 1996 21:44:24 GMT From: Chad McWilliams Subject: Re: Help - Novell 4.10 and IDE CD-ROMS >Anyone figured out how to make Novell 4.10 recognise IDE CD-ROMS? >Tried Novell, Ingram Micro and 3 specialist consultants. >Advice is, use 3.12, Use SCSI, and let us know if you manage it (Great >tech support Novell - yeh, right!). >Working with latest beta of CDUP2.exe Sure, I can use SCSI, but not the >point is it... Here's the commands: LOAD IDEATA.HAM (YOU WILL BE ASKED FOR INT AND PORT) LOAD IDECD.CDM (SHOULD BE IN CDUP2) LOAD CDROM That's it. Enter CD DEVICE LIST for listing of CDROMS attached and CD MOUNT 1 (or whatever device number Netware assigns to the CD) to mount it. This has worked well for me (the driver is less than perfect though) If this does not work, check and make sure your system is able to talk to the CD.

We at Ohio Wesleyan University just went through the process of adding a tower to our network and are using a product from Microtest, Inc. (4747 North 22nd Street, Phoenix, AZ 85016-4708 (602) 952-6400), called Discport that will connect to a tower with up to 7 drives. It attaches to the network and the tower and comes with Discview software for configuring, mounting and mapping the drive towers as NetWare volumes. It cost us around $550.00 (educational pricing). They also sell a product call CD-NOW! which includes a modified version of NetWare 4.1 from which you can set up a dedicated cd server. The Discport product works fine for us right now, but if we start adding many more CD to the network, I can see us going to the CD-NOW! product. You can purchase towers from Microtest also. We went with a tower that was produced by Todd Entrprises, Inc.(31 Water Mill Lane, Great Neck, NY 11021, (718) 343-1040) because we got a great deal through a non-profit organization we belong to. ------------------------------ Date: Fri, 23 Feb 1996 23:09:05 PST From: "Orlando L. Stevenson" Subject: NetWare Jukebox Issue Jukebox product selection issue for those interested ... While discussing another matter (new DLT backup system)- a rep. of an application developing firm working on imaging software system stopped in to talk with my internal client; they've been struggling to find a solution for accessing multiple optical media in a 16 platter (20G) jukebox via single drive letter (i.e. 'O:') with SCSI Express and NetWare 3.1x. According to the Vendor, going to a pure UNC path (instead of raw drive mapping) is not an option at this point with the software mix. Poor performance and inflexible media changeout make volume spanning the media unworkable. The rep explained that going to a Microsoft NTAS/SCSI Express mix will solve the problem by offering a single drive mapping 'O:' with optical media loaded/mounted as subdirectories- (like mounting UNIX slices onto the 'root' partition). The Oracle database for stored image file paths would point to the exact media while the application mix gets the single drive mapping required. My question is what mainstream NetWare product is available to mount jukebox optical media in a similiar, directory oriented manner? Perhaps some sort of NFS for NetWare? ------------------------------ Date: Tue, 02 Apr 96 21:41:00 -0500 From: eric.engelmann@wdn.com (Eric Engelmann) Org.: World Data Network BBS. Since 1984.

It >would seem that combining all of your CDs into one volume would be an >easy way to reduce your memory requirements. I am not totally sure here, but believe that the 8 MB requirement means that you must have a Netware server with at least 8 MB of RAM. The software itself uses not more than a couple of MBs. Cacheing info about the CD volumes uses another MB for every 2-3 CDs (from my practical experience). Combining them into a single volume won't reduce this, as it surely depends on the amount of information present, not on the number of physical volumes. At least on a 3.x server, CD volumes use less resources than a disk volume of comparable size, as the CDs use 64k allocation and do not (obviously) need any write caches. >I have not seen any significant changes in utilization percent since >installing this new software. We have seen a similar result in our earlier discussions on memory requirements. Users who access the CDs do not simultaneously use other resources on the server. Much of the info on the CDs are probably infrequently accessed and does not cause much extra net traffic of server CPU resources. If any part is actually in frequent use, it will be cached by the server anyway (whether it's a CD or a hard disk). ------------------------------ Date: Tue, 9 Apr 1996 09:44:59 EDT From: Kacy Koelliker Subject: Re: Discport towers For a little bit over $2000, you could buy a 9 gig drive and some extra ram for your netware server. With that amount of space, you could copy at least 14 cdroms up to this volume. Your applications will run more than twice as fast with half the network traffic as the discport towers. I am running cd-now! and discview pro on a 14 cd tower and it will NEVER compare to the speed and performance of a hard disk based volume. With compression enabled, I am running 15 cds on an 8 gig drive and I still have 4 gig left! I realize that this approach will not be feasable for everyone, but has anyone considered this route? ------------------------------ Date: Wed, 10 Apr 1996 23:08:25 -0400 From: Glenn Fund Subject: Re: DiscPort CD-ROM Tower Before you buy, you might want to try: Compact Devices new TopSpin. http://www/devices.com (800) 894-0519 $795 Concurrently supports NetWare, NFS mounts and Web Browser access and administration.

(ncopy d:\*.* SERVER\CDVOL:CDONE /S /E) SERVER\CDVOL:CDONE SERVER\CDVOL:CDTWO SERVER\CDVOL:CDTHREE and so on... 3. make some adjustments to your applications' batch files: before after --------------- -------------- @ECHO OFF @ECHO OFF J: MAP ROOT J:=SERVER\CDVOL:CDONE LAUNCH.EXE J: LAUNCH.EXE MAP DEL J: and so on... 4. to update DATAONE without downtime, create a subdirectory called called TEMP and copy the new cd up the server. then go into filer, rename DATAONE to DATAOLD and rename TEMP DATAONE. Then deltree the old cd data. Pros: cost (microtest wanted to charge us $1000 for a jukebox driver for CD-NOW!) No downtime VERY FAST performance less space in our server closet (A full height hard disk is about 1/20th the volume of our 14 cd tower) Cons: the time it takes to install/update the cd maintenance of the batch files some cds require MSCDEX.EXE, but I haven't experienced this yet don't get me wrong, CDROM is great for distribution of data...but, eventually there will be a bunch of other options available to us. For example, we use an application called CALI (computer assisted legal instruction). The original distribution comes on CD and the updates are available on the Internet. So for us, it makes much more sense to copy this CD onto a hard disk and update it online. ------------------------------ Date: Sun, 14 Apr 1996 22:17:47 -0400 From: Glenn Fund Subject: NetWorld+Interop Las Vegas '96 In Review TopSpin, Compact Devices, http://www.devices.com, (800) 894-0519, $795 Instant CD-ROM server that supports from one to seven CD-ROM drives.

CD-ROM players are slow no matter what, and if a request is made to perform an action that takes a long time, say a seek, then it is quite possible for the cpu to be tied up waiting for it to complete. Naturally other things can be halted during that process by not receiving cpu attention. Whether or not this happens depends on the IDE devices, in detail. SCSI has a "SCSI bus disconnect" feature which allows devices to say "I got the message, I'll call you back later" and free the bus for other work. IDE was designed for DOS machines which have nothing else to do in the meanwhile; NW servers are exactly opposite to this. We recommend not using IDE anything on servers.

As long as we were using Netware 3.1x, we couldn't bring ourselves to Novell's cdrom.nlm. It was much to buggy and too slow. The situation changed at the end of last year, when we decided to update all the servers to Netware 4.10. After extensive testing, we were convinced, that the new cdrom.nlm in Netware 4.10 does its job quite well. Since January 96 we have Netware 4.10, and a on one server a maximum of 3*AHA2742T and 42 CDROMs (yes, we use all of them, special brackets to bring the second SCSI-bus out of the server are available). It works flawlessly, mounting time is not longer than with SCSI-Express, about 10-60 seconds for each CD. Only the first time you mount the CD, it can take much longer (several minutes). The time is needed for making the index file on the servers harddisk. This indexing is much faster, if it's already on the CD as for example on the NSEPRO. On other servers we mixed AHA2742T and AHA29?? (PCI), no problems. ------------------------------ Date: Wed, 24 Apr 96 07:01:42 PDT From: bfarrell@mindscape.com To: netw4-l@bgu.edu Subject: Re: IDE Mounted as a volume >I just received a call from a fellow school admin (on the othere side >of our province) that says he has a IDE CDROM that he cannot mount as a >volume. ....that there is not a driver for it.

For IDE CD-ROM drives you'll need the latest type of Novell drivers. Which is actually a set of two, because Novell has split out the components of the *.DSK drivers into *.HAM (Host access Module) and *.CDM (? Device Module - I've forgotten what the "C" is for!) These files work with the Novell NWPA.NLM (NetWare Peripheral Architecture) system. All the necessary files are in a Novell patch file named CDUP3.EXE available through Netwire, ftp, etc. Plus there is a good readme explanation of the whole system. - This also works under v.3.12 - It's important to note, however that not all IDE paddleboards will necessarily work with this.

It's the full version, only limited to two CD images and will expire after a few weeks. I did. It worked. I bought a copy. It works. The only drawbacks appear to be: *Dos/Windows/Windows95 only eg not NT. *Uses real mscdex, which takes up memory on a workstation *CD images, although compressed, still can take up a fair bit of space plus can take a while to create initially. Those would appear to be the main problems I've found so far. Personally, I can easily live with them. Accessing info from a CD image is blazingly fast, it is easy for my people to support, disk space is cheap and in any case I can backup the images to tape if they aren't frequently accessed plus a lot of CDROMs have less than 100megs of data on them so some images end up being comparatively small, and although mscdex takes up memory on the workstation it is genuine mscdex and so far I have not had any compatability problems and do not expect to find any. Using this software I do not have to maintain a special tower of CD drives, do not have to upgrade them from double speed to quad speed to hex speed to oct speed to who knows what speed, access speed to CD images is pretty much the same no matter how many people are accessing the one image at the same time, traffic on the network is kept to a minimum as requests for data don't get duplicated on the network (as happens with some systems), and future expansion is dead easy and inexpensive to do. Basically this may not suit everyone, but it's a neat solution and I highly recommend checking it out. ------------------------------ Date: Wed, 26 Jun 1996 19:21:07 +0000 From: Michael Gaskin To: netw4-l@bgu.edu Subject: Re: How can I put 200 CD-ROMs on line? >A friend has asked me the title question, how do I put 200 CD-ROMs on >line.

The Novell Netwire page has no info and neither does CD HELP. There are several pages of on-line help included with the cdrom.nlm. Type 'cd help' several times, you will see that each time the command is exectuted, you will be presented with different help options. If memory serves, I believe there are ten or eleven pages of help in total. The particular syntax you require is: cd mount {volume name or #} /mac Executing 'cd device list' will present you with the volume name and number of the cd's in all NetWare cd-rom devices. 'cd volume list' will list all volumes ever mounted that have index records stored on the server. Every now and then I have found it a good idea to re-index the file (cd mount {volume name or #} /r), this is usually done when users start complaning that they cannot map to the volume, or map to it, but receive incomplete or no directory listings. ------------------------------ Date: Tue, 7 Jan 1997 07:00:00 GMT From: "Forrest H.

SCSI CD Towers are easy to build: The simpler you keep them, the better they work! Personally, I like the 7 drive configuration: One cable, one box, 1 SCSI card, 7 drives. Here are a few hints: 1) Don't go overboard on 6X or 8X drives: 4X (or ~600 kilobytes/sec sustained transfer) is about the limit you'll see on a quiet 10Base ethernet anyway... Even 2X drives will be fine in most every case; 2) CD changers can be a double-edged sword: If you have lots of disks and just a couple of users, then changers are fine... Just spread out the most commonly used disks over the changers, so that two users will not trying to access different disks on the same mechanism; 3) Make sure the CD drives you buy are ASPI-compliant: This way drivers will only be a minor issue -- Or if you use an NT server then the drivers for ASPI CD/ROM drives are integral to the OS; 4) If you DO decide to use changers, personally I like the Nakamichi MBR-7, since it is fully ASPI compliant. This is also private labelled under the "Mountain" label as their CD7. You can pick up new Nakamichi 2X MBR-7's for $100 each... That's $$14 per mounted disk!; [As I'm writing you, at this moment I'm putting the finishing touches on a baby DEC Alpha Multia with NT/Server 3.51 and NT/Workstation 4.0 (dual boot) and a Mountain CD7. It's REALLY nice to plug the CD into the SCSI port and have not only NT recognize all 7 disks in the File Manager, but also have the first disk recognized at the ARC console!]; 5) I've never really cared for the DiskPort: For what one of these boxes cost you can actually use a 486 or low end pentium to do the real thing. In addition, the DiskPort uses one NetWare user license... If you're right at the limit it can be expensive!; 6) Check out the Classifieds -- Both the Mac as well as the PC sections -- on America Online for deals on CD players. As of this morning, prices at MacResQ (888-44-RESCUE) are running $49 for new Apple 300i+ (2X tray load) and $79 for "pull" Apple 600i (4X tray load) players: These two players are ASPI - compliant as well; 7) Use active terminators... This is true for any modern SCSI chain, by the way; 8) Contact Granite Digital (510-471-6112) for nice 7 drive tower cases: They run about $200 or so. ConStor (in City of Industry, California) is also another excellent source for 7 drive cases. When the cases arrive, just pull out the SCSI ID selector switches, set the jumpers from 0 to 7 on the drives themselves (to avoid any foul-ups:), plug everything in and away you go! ------------------------------ Date: Thu, 6 Mar 1997 06:17:12 -0500 From: Dan Schwartz Subject: Couple of things... >>I have built a server using the following components: >> >>Two Western Digital Enterprise 2110MB WDE2170-0007 SCSI drives >>One Adaptec 2940 AU host adapter >>8 x 32MB SIMM >>Asus P/I-P65UP5 with a C-P6ND board, BIOS version 02.05 >>One 200MHz PentiumPro >>One 3COM 3C900TP Etherlink XL board >>An ATI Videocharger 1MB VGA board >> >>Problem: if the computer is warm-booted or if the reset button is pressed >>the AHA2940 is unable to find the hard drives.

Three things: The AHA-2940UW and AHA-3940UW share the same BIOS code and SCSI command set, so I'm quite surprised that the drive would work with one and not the other. I'm NOT surprised that the Ultra-Wide Adaptec cards can cause trouble, as I reported here several weeks ago flakiness in my DEC Alpha running NT/Server 3.51 when I installed an AHA-2940UW into it... And the troubles went away when I dropped in an AHA-2040 card. [Turns out that one needs an ARC firmware update to use the Ultra-SCSI cards...] Also, beware that there are two series of 2940, 2940U, 3940, and 3940U series of Adaptec SCSI adapters: The "AHA-2940" series, and the "Power Domain-2940" series specifically for the PCI bus PowerPC Macs. Turns out that besides the Mac cards having different firmware (to accomodate the little endian byte order like the DEC Alpha), there are also three resistors that have different values, so the AHA and Power Domain series cards are not interchangeable. To change the write cache enable (WCE) parameter, you need to go to drive parm page 8 and set the WCE flag. Personally, I use HDT World Control on a Mac to handle all my heavy duty SCSI work... (Whaddya expect me to say, I use a pee cee for those chores?! :) Lastly, you referred to the target ID ("TID" or "ID") as the LUN (Logical Unit Number): These are two totally separate items. Each SCSI target ID can support up to 8 LUN's: This is a throwback to the old days when a SCSI drive controller was actually a card in the machine and not on the drive itself: Each drive on a given TID could have up to 7 LUN drives attached.

Searching relational databases on a CD is painfully slow; and/or with flat databases and/or across multiple CD's it's a wasteland. 21 CD's * 650 MB/CD = 13.6 gigs: Drop the data onto a couple of 9 gig hard drives or three 4.3 gig drives and the searches will be sped up by over an order of magnitude. (I just ran into this with a 6 disk CD server at a collection agency with US phone numbers, used for skip tracing). Second, the cost of the hard drive solution would probably be LESS, because if you figure on about $200 for a SCSI 8X CD/ROM + ~$30 per bay for a 7 drive tower, that's over $5,000 for 21 drives... 9 gig Seagate 5400 RPM drives are about $1700 each -- Faster, and costs less, too!

Well, now you're back in the CD speed jackpot: If you're using CD players, fiber is a waste of $$$ because you wouldn't even come close to filling a 10Base cable. On the other hand, if you transfer the data to a hard drive, then fiber may not be such a bad idea... Although I much prefer 100Base-TX due to it's far better industry support, more competitive marketplace, and concomitant lower costs per node. Make a rough estimate of the costs of the cabling of the two methods (fiber vs copper); and ask the guy in the county ISS department if *HIS* department will foot the bill for the difference...

The new version comes with weblaunching software and browser plugins, but I have not yet experimented with that yet. The biggest down side I have experienced is the amount of server ram required (though this can be reduced depending on your needs). On a 4.10 server you need about 1MB per cdrom drive that is permanetly mounted as a netware volume. Of course depending on usage you do not need to keep these volumes mounted all of the time. I would also look at the Microdesign SCSI Express products. They recently had a sale, and I remember you could get their 7 drive cd tower, software and cable for under 1500.00. Their towers attach to the server scsi interface. If you have disk space, or not too many cdrom discs, you may also be able to just copy the cdroms to netware volume. I do that with some discs that are updated infrequently, and where the software permits this. ------------------------------ Date: Tue, 13 May 1997 18:19:41 -0700 From: Joe Julian Subject: Re: CDROM Deactivated by driver >Are there any known problems or issues with Novell's CDROM.nlm? >I commonly get "Device deactivated by driver due to device failure" >when I mount a CD on the servers CDROM as a NW volume... This is normal and correct. Netware deactivated the device when changing CD's to force the driver to re-load the volume information. If this is not done (like if you dismount a CD then mount a different one without deactivating the device first in monitor), Netware uses the wrong volume table for the device (*). When you map the new disk, you will see file abcd.efg from the first disk (though the data it reads will be from the new disk, totally screwing things up). (*) At least this is what happens when the CD is renamed to a consistent volume name. As in renaming every CD to "CDROM" for easy volume mounting. ------------------------------ Date: Mon, 9 Jun 1997 00:52:12 -0700 From: "Philip J. Koenig" Subject: Re: Removing CDROM volumes from NDS?

Fabulous, yours was the most informative answer so far. Certainly this gets done during Netware install then, I may have not understood the implications of the abovementioned question during install. ------------------------------ Date: Tue, 29 Jul 1997 02:42:02 -0700 From: Joe Julian Subject: Re: How do you mount a cdrom? >>CD support is a different animal on IntranetWare.

It, of course, doesn't remove the files from the CD, it just removes the entry in the CDROM.NLM built index. When the CD is next mounted (if you use the /r) the deleted files will be back. After "deleting" files from a CD, I haven't tried purging. That might be a fun way to see if you can take down the server. Try it at about 2:30pm on a Friday...

Remember that the way PC's, i.e., Windows 95, Windows NT, etc., get the 24X CD-ROM is by buffering that CD-ROM to disk. In fact, there is a 100X CD-ROM on the market that require a huge disk cache. Netware, on the other hand, is a file and printer server. Any caching or buffering of the CD-ROM drive has to happen on the local PC, which is then limited by the across-the-wire transfer time. ------------------------------ Date: Mon, 15 Dec 1997 20:35:51 -0500 From: Nathan Durland Subject: Re: Sharing CD-ROM on Netware 3.12 Network >Take your pc, put Windows 95 on it, add Microsoft's "File and printer >sharing for Netware networks" set it to sap and authenticate to your >novell server, then share your cd drives.

At our site, punishment for such an action would be swift -- your PC would be replaced with an 8Mhz 286 running WordPerfect 4.x for DOS on 512K of RAM, a green monochrome screen, and a keyboard with both ALT keys broken. Microsoft's "File and print Sharing for Netware networks" is a mistake from the word go. It lies to all the clients that it is a "real" novell server (its not), and it will cause your machine to excessively advertise its presence on the network, causing a serious performance hit. If you must do this (and only in a small network), install Win95 and the client for Microsoft networks. Tell it you want to "share my files with others" -- this installs the "File and Print Sharing for Microsoft networks". Still noisy, but not as bad. Then install the Novell client32. The best solution, though, is to buy a 9GB SCSI drive for the server and xcopy the CD's to it. For a kilobuck or less, you can add enough storage to your server to hold 20 or so CD's, and the performance is MUCH better. ------------------------------ Date: Tue, 16 Dec 1997 08:33:56 -0600 From: James E Borchart Subject: Re: CD-ROM's >A response to your short letter regarding the CD-Rom's on a Elite >Seagate (Sales pitch ??????) verses something like the NEC CD-Changers. Actually I work nowhere near sales, and we can barely make elite 23's fast enough to meet demand, so this wasn't a sales pitch, remember that I said we bought the discport first! I believe that Seagate is the only company that makes hard drives with a physical size greater than 9GB. Of course, the opinions expressed in this message are mine and do not necessarily reflect the opinions of my employer. >First point of view - Changers are ALWAYS slower, it's a known fact and >is clearly stated in all sales brochures that I have looked at, if you >compare access times to changers verses regular CD jukeboxes.

I agree with this paragraph, but disagree with the premise. As an administrator I only care about end-user performance and capacity, and I will look at them raw. I don't care what the topology is. I have many servers with a built-in CD-ROM and am comparing those also. In fact I have a server with a NEC 7 disc changer directly connected to the server, and a hard drive is STILL much faster. >Second point of view - Copying the Cd's to a server will definetaly >increase access time to the data.

Actually the compress/uncompress hasn't impacted performance at all, the server is running novell DHCP, a known hog, and it is a 486/66, and we haven't had any issue's, even though we left the compression configuration at the default values. >Final view - If you are already going to use a Netware server to copy >CD's to, I would NOT use compression on that drive, no matter how strong >the box or disks.

I would have assumed this also, but we have been running for months and have never experienced this problem. What we found is that many files on a CD-ROM are never accessed (esp the win95 and NT workstation distribution CD's.) Those are the ones that are compressed. I do not recommend turning off compression, if you did that, then connecting regular CD-ROM's in a jukebox configuration starts to make sense, except for performance. Someone else noted that they were looking at a jukebox that would hold around 200 CD's. One Elite 47 drive, or two Elite 23's, can probably hold about 200 CD's for around $6000 US. I don't see any reason for a fight on this, the statements above are simply my experience. If you don't like it, then don't use it. ------------------------------ Date: Mon, 26 Jan 1998 22:24:38 +0000 From: Randy Richardson Subject: Re: CD ROM HIDEEN INDEX FILE >Is there any solution for increasing the size of the hidden >CD index file, i always get disk full errors when i try to >execute programs.. (sorry if it is obvious) If you have been mounting a lot of CD-ROMs in the past, it is possible for your indexes to build up and consume disk space. Run the following command once in a while to remove all inactive indexes: CD PURGE If you need to do this often, get Novell's CRON.NLM to do it for you (it's very reliable, and doesn't need to be walked or fed). ------------------------------ Date: Thu, 29 Jan 1998 10:58:04 -0700 From: SSgt Scott Jones Subject: Re: CDROM Tower/Server >I'm running 4.1 (soon to be 4.11) on a 16Mbps Token Ring network and >I have to spend a goodly amount of money in a hurry or it will disappear >into somebody else's budget. > >Does anybody have any suggestions/experience as far as CD-ROM >servers go? Brands I should look at, ones I should avoid...etc. I have the extreme displeasure of supporting 9 Procom Towers using Microtest Discview and the Discport NLM. The discview software is a joke, and the NLM will abend a server if the server comes up or goes down and the tower is offline. I also have a pair of Logicraft LAN-CD (all inherited) towers, even a bigger joke. These proprietary pieces of junk are about to become psuedo NetWare machines used to serve the CD's only. I am looking into an Axonix CD-ROM Sharer which is a small box jammed full of UW-SCSI hard drives. The one I'm looking at has a minimum capacity of 48 CD's, and a 100Mbit ETHERNET port, for less than $11,000. If you don't have a lot of CD's to put online, my preference would be a good SCSI card in a server and a tower attached to that using CDROM.NLM.

To support CDROMs on your server, you'll need to load CDROM.NLM, and the latest version is available at the following URL: http://support.novell.com/cgi-bin/search/patlstfind.cgi?2932066 If your CDROM reader(s) is(/are) connected to a secondary IDE channel (SCSI is preferred), you'll probably need to load the IDEATA.DSK driver for the secondary IDE port. If your CDROM reader(s) is(/are) connected to an Adaptec SCSI controller, you'll probably need to load ASPICD.DSK after loading the SCSI disk drivers. For other SCSI adapters, you'll have to consult the manuals (just post another question to this list if you can't find the information there). ------------------------------ Date: Thu, 26 Mar 1998 10:15:04 +0100 From: Jiri Polach Subject: Re: AXIS cd-rom servers. >Like clockwork, the two AXIS servers will lose and regain communication >with SERVER1.
