v
The server provides one PCIe riser-card slot on the system board. The riser-card
provides three PCI Express Gen3 adapter slots (see “PCIe riser card” on page 33
for the location of the PCIe slots on the riser card). The system board provides
five additional PCI Express Gen3 adapter slots (see “System-board
optional-device connectors” on page 31 for the location of the PCIe slots on the
system board). Some models come with the PCIe riser-card assembly with
brackets installed. The following table lists the PCIe slots on the riser-card and
the system board, the microprocessor to which each slot is connected, and the
supported adapters that you can install in each slot.

Note:
v
The x16 (x8) designation for a PCIe slot identifies a x16 slot that is wired for x8. If you install a x16 adapter in
this slot that can downshift to the x8 bandwidth, it will run at the x8 bandwidth. The x16 connector can be used
for x8, x4, x2, x1, and x16 adapters. Check the information that comes with your adapter for compatibility
information.
v
The server also supports PCIe Gen1 and Gen2 adapters.
v
The server comes with an onboard RAID controller that provides basic RAID
levels 0, 1, and 10 functionality. The server supports optional RAID controllers,
RAID cache cards, and Feature On Demand software RAID that you can
purchase for additional RAID levels 5, 6, 50, and 60 support. For configuration
information, see the documentation that comes with the adapter or the
ServeRAID documentation at http://www.ibm.com/supportportal/.
For more information about the supported adapters, see Table 16 on page 68. For
more information about the supported RAID cache cards, see Table 17 on page
70. For more information about the supported Features on Demand (FoD)
software, see Table 18 on page 71.
