5786-8203 - IBM Power6 E4A TotalStorage EXP24 Disk Dwr

The IBM Power6 8203-E4A (#5786) TotalStorage EXP24 Disk Dwr

Provides disk slots for up to 24 disk units in a 19-inch, 4 EIA high rack drawer. The #5786 provides redundant power, redundant cooling, and Ultra 320 SCSI interface connections for 24 Ultra 320 SCSI disk units that 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 #5786 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/#5776/ #5782 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 #5742s 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
