EJ0S is IBM's PCIe3 x8 SAS RAID internal adapter 6 Gb, second adapter for the split storage backplane (CCIN 57D7). Listed for 8286-41A, 8286-42A, 8247-42L.

A second built-in drive controller that splits the 12 internal drive bays into two groups of six, so two partitions can each own their own drives.

Before you order EJ0S

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.
