52 IBM Power System S822 Technical Overview and Introduction
The 2.5-inch or small form factor (SFF) SAS bays can contain SAS drives (HDD or SSD)
mounted on a Gen3 tray or carrier (also knows as SFF-3). SFF-1 or SFF-2 drives do not fit in
an SFF-3 bay. All SFF-3 bays support concurrent maintenance or “hot plug” capability.
Additionally, as an optional for the #EJ0U backplane, the feature #EJTL adds a 6-bay 1.8-inch
SSD Cage behind the server bezel. All six bays are accessed by both of the SAS controllers
and the bays support concurrent maintenance (hot plug). At the time of writing, the supported
disk on these bays is feature #ES16, 1.8-inch SSD with 387 GB capacity.
The SSF-3 disk drives connect to the DASD backplane and are hot-swap and front-accessible
while optional the 1.8-inch SSD driver are housed behind the server bezel but also hot-swap
once you remove the front bezel.
Server front view considering both backplane option can be seen on the diagram on
Figure 2-17.
