e. Complete the following steps to cable a configuration that includes two hard-disk-drive partitions,
nine disks per hard-disk-drive partition, and two SAS adapters.
Note: You must have a minimum of one disk drive per hard-disk-drive partition.
1) Set the hard-disk-drive partitions switch to position 2. The hard-disk-drive partitions switch is
located at the rear of the 5802 expansion unit, just below the SAS connectors.
2) Choose one of the following SAS adapter and cable combination options:
v Two FC ESA1 adapters (PCIe2 RAID SAS Dual-port 6 Gb) cabled with two FC 3689 cables
(AT 0.6 meter - HD SAS)
v Two FC 5901 adapters (PCIe Dual - x4 SAS) cabled with two FC 3688 cables (AT 0.6 meter -
Mini SAS)
3) Attach an AT cable (B) from one port on one SAS adapter (A) to SAS connector 1 on the 5802
SAS conduit card (C), as shown in the following figure.
Figure 19. Configuration with two hard-disk-drive partitions and two SAS adapters
4) Attach an AT cable (B) from one port on the other SAS adapter (A) to SAS connector 3 on the
5802 SAS conduit card (C).
5) Optional: Use other ports on the same SAS adapters to connect a 5886 disk drive enclosure or
5887 disk drive enclosure by using SAS YO cables (D).
6) Go to step 1i on page 25.
f. Complete the following steps to cable a configuration that includes two hard-disk-drive partitions,
nine disks per hard-disk-drive partition, a dual SAS adapter pair per hard-disk-drive partition that
controls the disks in the partition, and dual SAS connectivity to all drives.
Notes:
v For the following operating systems, this configuration must be a RAID configuration: AIX,
Linux
v You must have a minimum of one disk drive per hard-disk-drive partition.
1) Set the hard-disk-drive partitions switch to position 2. The hard-disk-drive partitions switch is
located at the rear of the 5802 expansion unit, just below the SAS connectors.
2) Choose one of the following SAS adapter and cable combination options:
v Four FC ESA1 adapters (PCIe2 RAID SAS Dual-port 6 Gb) cabled with four FC 3689 cables
(AT 0.6 meter - HD SAS)
v Four FC 5805 or FC 5903 adapters (PCIe Dual - x4 3 Gb SAS RAID) cabled with four FC 3688
cables (AT 0.6 meter - Mini SAS)
v Four FC 5901 adapters (PCIe Dual - x4 SAS) cabled with four FC 3688 cables (AT 0.6 meter -
Mini SAS)
