9009-ES84 Mainstream SAS 4k SFF-3 SSD

(#ES84) - 931GB Mainstream SAS 4k SFF-3 SSD for IBM i

931 GB SAS 2.5-inch (SFF) Mainstream solid state drive (SSD) formatted in 4224 byte sectors (4k). The drive is mounted on a 2.5-inch SFF-3 carrier/tray. Drive is rated at 6Gb/s though actual performance is dependent upon multiple factors.

DWPD (Drive Write Per Day) rating is 1 calculated over a 5 year period. See the following table for the approximate lifetime Total Bytes Written (TBW) supported by each drive capacity:

Drive Capacity     Total Bytes Written (TBW) in (TB)

931 GB               1700

1.86 TB              3399

3.72 TB              6799

Depending on the nature of the workload, the lifetime TBW may be somewhat larger.

Features #ES83 and #ES84 are physically identical drives with the same 5B28 CCIN. Different feature codes help the IBM configuration tools understand how the SSD is used. #ES83 indicates usage by AIX, Linux or VIOS. #ES84 indicates usage by IBM i.

Limitations:

• The drive is mounted on a SFF-3 carrier/tray to fit into a POWER8 system unit's SFF-3 bays. JBOD formatting of 4096 byte sectors is not tested or supported. Drive cannot be reformatted to 5xx byte sectors. 5xx and 4k drives cannot be mixed in the same array. Older SAS adapters such as PCIe2 or earlier do not support 4k drives.
• OS level required:
  • IBM i supported
