(#5787) - TotalStorage EXP24 Disk Twr
Provides disk slots for up to 24 disk units in a stand-alone disk tower. The #5787 provides redundant power, redundant cooling, and Ultra 320 SCSI interface connections for 24 Ultra 320 SCSI disk units, which are organized in four independent groups of six disk units.
#5741 and/or #5742 EXP24 Disk Slot Enablers (SCSI repeaters) enable these groups of six disk unit slots. The enabled disk slots are driven by SCSI disk controllers located outside the #5787 and connected by a SCSI cable. One to four Disk Slot Enablers are required, depending on the number of disk unit groups populated with disk units.
One external port on a disk controller such as a #5736/#5737/#5739/#5775/#5776/#5778/#5781/#5782/#5799/#5800 is required for each #5741 installed. Likewise, one external disk controller port is required for each #5742 installed and cabled to run one group of six disk slots. Alternately, two #5742's can be cabled such that a single disk controller can run two groups of six disk slots. Or, one #5741 plus one #5742 can also be cabled such that a single disk controller can run two groups of six disk slots.
The following SCSI cables are available:
- #2138 0.55m SCSI Cable
- #2124 1m SCSI Cable
- #2125 3m SCSI Cable
- #2126 5m SCSI Cable
- #2127 10m SCSI Cable
- #2128 20m SCSI Cable
Specific disk unit feature numbers are used to identify disk units which will be placed in the #5787. These disk units are physically the same disk units as used in other System i system units and I/O tower/drawers. Using separate feature numbers allows IBM configuration tools to better understand their placement. Feature numbers of #5787 disk units include: #1266, #1267, #1268, #1293, #1294, #1295, #1296, #1297, #1298 and #1299.
