Included in the feature EJ0T or EJ0U backplanes is a slimline media bay that can optionally
house a SATA DVD-RAM (#5771). The DVD drive is run by the integrated SAS controllers,
and a separate PCIe adapter is not required.
The Power S822 supports the RDX USB External Docking Station for Removable Disk
Cartridge (#EU04). The USB External Docking Station accommodates RDX removable disk
cartridge of any capacity. The disks are in a protective rugged cartridge enclosure that plug
into the docking station. The docking station holds one removable rugged disk drive/cartridge
at a time. The rugged removable disk cartridge and docking station backs up similar to tape
drive. This can be an excellent alternative to DAT72, DAT160, 8mm, and VXA-2 and VXA-320
tapes.
Table 1-6 shows the available media device feature codes for Power S822.
Table 1-6 Media device feature code description for Power S822
SCSI disks are not supported in the Power S822 disk bays. Also, because there is no PCIe
LP SCSI adapter available, you cannot attach existing SCSI disk subsystems.
If you need more disks than are available with the internal disk bays, you can attach additional
external disk subsystems. For more information about the available external disk subsystems,
see 2.8, “External disk subsystems” on page 60.
For more information about the internal disk features, see 2.6, “Internal storage” on page 51.
1.6 I/O drawers for Power S822 server
At the time of writing there is no PCIe I/O drawer supported on the Power S822.
Customers migrating from earlier generation Power Systems servers may have been using
I/O drawers such as the GX++ attached feature 5802 or 5877 PCIe 12X I/O Drawers with
PCIe Gen1 slots. Though most of the disk drives in the feature 5802 can be converted and
moved to the feature 5887 EXP24S drawer, the feature 5802 and 5877 drawers are not
supported on this newer Power System built with POWER8 based technology.
Similarly, the GX++ attached EXP30 Ultra SSD Drawer (#EDR1 or #5888) is not supported.
Also the 3.5-inch-based feature 5886 EXP12S SAS Disk Drawer and feature 5786 EXP24
SCSI Disk Drawer are not supported.
IBM offers the IBM System Storage® 7226 Model 1U3 Multi-Media Enclosure that can hold
one or more DVDs, tape drive, or RDX docking stations. For more information about the
multimedia drawer, see “IBM System Storage 7226 Model 1U3 Multi-Media Enclosure” on
page 18.

Statement of direction: IBM plans to introduce an PCIe I/O drawer which will expand the
number of PCIe Gen3/Gen2 slots available on POWER8 processor-based Power Systems.
