Table 2-12 shows available RAID and SSD SAS adapters for the Power S822.
Table 2-12 Available SSD SAS adapters.
The 177 GB SSD module with enterprise multi-level cell (eMLC) uses an enterprise-class
MLC flash technology, which provides enhanced durability, capacity, and performance. One,
two, or four modules can be plugged onto a PCIe RAID and SSD SAS adapter, providing up
to 708 GB of SSD capacity on one PCIe adapter.
Because the SSD modules are mounted on the adapter, to service either the adapter or one
of the modules, the entire adapter must be removed from the system.
Under AIX and Linux, the 177 GB modules can be reformatted as JBOD disks, providing
200 GB of available disk space. This way removes RAID error correcting information, so the
best approach to prevent data loss in case of failure is to mirror the data by using operating
system tools.
2.5.6 Fibre Channel adapters
The systems support direct or SAN connection to devices that use Fibre Channel adapters.
Table 2-13 summarizes the available Fibre Channel adapters, which all have LC connectors.
If you are attaching a device or switch with an SC type fiber connector, then an LC-SC 50
Micron Fiber Converter Cable (#2456) or an LC-SC 62.5 Micron Fiber Converter Cable
(#2459) is required.

NPIV: The use of N_Port ID Virtualization (NPIV) through the Virtual I/O server requires an
NPIV-capable Fibre Channel adapter, such as the #5273, #EN0B and #EN0Y.
