Re: IBM 3584 L32 LTO configuration question
I think would be prudent to put only 2 drives per SCSI interface so that you do not overrun the bus. Maybe this is what you mean. You an run as many as you want up to the limit of the system's slots.

Re: IBM 3584 L32 LTO configuration question
Hi Kevin, About your question I know that these are the possible SCSI attachments for the 3584LTO library: 7.5.3 Netfinity systems The IBM 3584 UltraScalable tape library can be attached to Netfinity systems supporting Microsoft Windows NT 4 with service pack 6 or Windows 2000 operating systems and the following adapter: ? Wide Ultra2 SCSI PCI Adapter (#33L5000) 7.5.4 Intel-based systems The IBM 3584 UltraScalable tape library can be attached to systems supporting the Microsoft Windows NT 4 with Service Pack 6 or Windows 2000 operating systems and the following adapters: ? Adaptec 29160 LVD SCSI adapter ? Adaptec 39160 LVD SCSI adapter (VHDCI connector) ? Adaptec AHA-2940U2W Ultra2/Wide LVD SCSI adapter ? Symbios Logic SYM22910 64-bit PCI-to-Ultra2/SCSI Dual Channel Host Adapter (LVD) ? Netfinity 33L5000 Ultra2 adapter ? Adaptec AHA-2944UW PCI-to-Ultra Wide Differential SCSI Adapter (HVD) About cabling and interposer: 7.6 SCSI cabling A SCSI cable is required for each server connection to a SCSI bus; you can have up to 12 SCSI busses per IBM 3584 library frame. One host SCSI cable should be specified on the initial order for each host attached; a terminator and 0.5m drive-to-drive cable are supplied with each drive. An interposer (a connector which matches the pin pattern of the host adapter to the pin pattern of the cable) may also be required for attachment to certain server adapters. 7.6.1 Cables One SCSI differential terminator and a 0.5m drive-to-drive cable are included with each tape drive ordered (feature #1454 LVD or #1455 HVD). The 0.5m drive-to-drive cable is designed to add drives on a single bus; it is not suitable to connect drives to the host systems. Additional SCSI cables are available as optional features on the IBM 3584 for both LVD and HVD attachment to host adapters. The cables can be used with an HVD Ultra SCSI bus or LVD Ultra2 SCSI bus. The following cables have an HD68 connector on each end: ? Feature #5305, 5m (16.5 ft) universal SCSI cable ? Feature #5310, 10m (33 ft) universal SCSI cable ? Feature #5318, 18m (60 ft) universal SCSI cable ? Feature #5325, 25m (82 ft) universal SCSI cable The following cables have VHDCI connectors at the host end and HD68 connector to the drive: ? Feature #5604, 4.5m (15 ft) universal SCSI cable ? Feature #5610, 10m (33 ft) universal SCSI cable ? Feature #5620, 20m (66 ft) universal SCSI cable ? Feature #5625, 25m (82 ft) universal SCSI cable 7.6.2 Interposers An interposer is required to connect host adapters that do not have HD68 connectors to the SCSI cables. The following chargeable features supplying interposers are available: ? Feature #2895 interposer to connect AS/400 adapter #6501 ? Feature #5099 interposer to connect a Mini-68 pin VHDCI connector to the 68 pin HD68 connector on the SCSI cable. This interposer (0.3m cable) has a male Mini-68 pin VHDCI connector on one end and a female 68-pin HD68 connector on the other. These are the official information you can find on IBM redbook "IBM Ultrium LTO Tape Libraries Guide". Hope this help!

Re: IBM 3584 L32 LTO configuration question
I apologize for my question being so generic. Let me try to nail it down better for everyone... I'm not interested in what others have done on W2k, AIX or RS/6000. I'm not interested in what other have done with SAN or Fiber. Most of what I saw in the archives dealt with these components. My question is specific to NT 4.0 and SCSI direct connect. I've been told that I can only have "two SCSI interfaces per TSM NT server". I was looking for some feedback on this. Thanks again!
