IBM Power 8 Storage controller and drive bays

8286 EJ0P: Expanded function storage backplane: 18 SFF-3 bays, DVD bay, dual IOA with write cache (PCIe3 x8 cache SAS RAID internal adapter 6 Gb, CCIN 57D8)

EJ0P is IBM's Expanded function storage backplane: 18 SFF-3 bays, DVD bay, dual IOA with write cache (PCIe3 x8 cache SAS RAID internal adapter 6 Gb, CCIN 57D8). Listed for 8286-41A, 8286-42A, 8247-42L.

The high-end internal drive setup for the Power S814 and S824: 18 drive bays, an 8-bay SSD cage, a DVD bay and two mirrored RAID controllers with write cache.

The p8hcd PDF gives 2 GB real write cache (8 GB compressed); the current IBM Docs page for the same adapter gives 1.8 GB (7.2 GB compressed).

Uses one PCIe slot (slot P1-C11 hosts the external SAS ports), so the server has one fewer PCIe slot with EJ0P.

Before you order EJ0P

The drive bay and controller setup decides how many drives the server can hold and how they are protected. Changing it usually means planning downtime, so check it against your machine type first.
