I need to purchase a r/w optical jukebox for use on a Sun network. The primary purpose of this jukebox will be for archives. The secondary purpose is for cheaper, on-line storage. For an optical jukebox to be useful to us, it must have most (if not all) of the following capabilities: 1) For purposes of archive, it should be possible to remove a disk or disks, send them to one of our other sites, and have them placed on-line in a jukebox ready to go. So, it should also be easy for me to walk up to the jukebox and grab the correct disks. It is my understanding that packages like AMASS can not provide this capability. If I can't find a system like this, I might as well buy a high capacity tape drive, save my money, and sacrifice on-line access. 2) At minimum, directories should span both sides of the the media and multiple disks. It would be nice if files could as well. For our designs, 300 (or 500) Mb/side is not useful without this capability. 3) The filesystems on the optical media should be accessible across the Sun network via NFS. You should be able to use regular unix commands to archive the data (tar, dump, cp, etc.) 3) There should be some sort of winchester cache to prevent mechanical "thrashing" of the jukebox, and to speed read access through indexing. I'd like the system to use my existing disk. 5) The jukebox shouldn't choke if I remove a disk (that isn't mounted), place unformatted media on-line, or place write-protected media on-line. 6) The system should be reliable. It should have a fairly large installed base with some satisfied users. 7) It would be nice if the system would allow multiple platters to be mounted. If I can find something that would satisfy number 1 and 6, I would be happy. thanks in advance --matt -- Matt Landrum | mdl@cypress.com Cypress Southeast Design Center | office: (601) 324-4609, FAX - 4614 1 Research Blvd, Suite 200 | "There's a fine line between Starkville, MS 39759 | stupid and clever" -- Spinal Tap
