Does anyone out there have any experience with using an optical disk jukebox. We are looking for such a beast. Ideally it should be read/write, but WORM would be acceptable. It needs to be SPARC compatable, capable of being conected to SCSI or VME. BTW, I don't know any large eunuchs, but there was a 6'11" tranvestite that attended the University of Florida in the late 70's... "Waste your brain, wax your board, and pray for waves!"

eastman kodak has great large worm jukeboxes. 150 disks, each disk is about 6.3 gigabytes in size. connects to suns via scsi. please ring jeff harris @ kodak (716) 588-0659 Ed Pendzik

Siemens/Nixdorf has an NFS-based optical jukebox system available called FMWORM. It supports both 5.25" (Cygnet) and 12" (Sony) jukeboxes; the larger jukeboxes each support up to 350 GB, and you can have several on a single host, and multiple hosts. Since it is NFS compliant, anything that works to a normal NFS file server will work to FMWORM (if you account for jukebox latency, etc.). Files are NOT staged; incremental writes to an existing file do not cause a rewrite of the whole file. If you are interested, I have more details available. --------------------------------------------------------------------------- Russell Crook, Nixdorf Toronto Development Centre 2235 Sheppard Ave. E., Willowdale, Ontario, Canada M2J 5B5 Ph: +1 416 496 8510 UUCP: uunet!utai!imax!nixtdc!rmc or rmc@nixtdc.UUCP "... technology so advanced, even we don't know what it does."

HP sells a Rewritable optical disk autochanger. The official part #'s and $: C1700A Rewritable opt. disk autochanger Series 6300 Model 20GB/A $39,950 Opt. 231 Delete media (all but one cartridge). -$ 6,450 Opt. AFJ Add on 2.0m SCSI cable $ 50 Ordering the C1700A gets you 32 pieces of media totalling 20GB of storage. I have heard that if one orders the C1700A without using Opt. 231, the shipping of the product can be delayed. It appears that it is best to order the product with Opt 231, and then order as much media as desired separately. (The media is the bottleneck in the shipping process).

Pinnacle Micro, sells a 6GB, 10 disk jukebox for approximately $10K. I've used one of their single disk systems but have no experience with this product. -- Scott Leadley - leadley@cc.rochester.edu

If its the one I think it is then it is more like 5GB. I have seen one and heard about a 50 disk and 2 drive version. They also have a REO 1300 which is just a 2 drive 2 disk version. This latter has the nice feature of being able to access two sides on the 2 disks as a single filesystem. This means you can have 500MB file-systems instead of the usual 250MB (per side) ones. I don't know if you can have the 50 disk juke-box configured to do this. It would offer more flexibility if you could mix 2 disk and single disk file- systems in the one jukebox.

The advertisement I saw implies that with a custom driver (which they can supply) you can bind all surfaces together as a large virtual disk. I like this feature, but would only use it in situtations where picker thrashing on files spanning surface boundaries was unlikely or unimportant (i.e. you have LOTS of time).

I know that Sun Coast Softworks (FLA) now has their Optimem SCSI driver available for IBM RS6000 systems (they've had a Sun version for some time). Some sites will be using this driver to manage Optimem drives in Cygnet 1800 series jukeboxes. I think I have their number and address. Email if you want it. They have a custom file system but will have, I'm told, an NFS version shortly. David Geller
