In 2-CPU configurations, there are two PCIe slots available (one full-height slot, slot 1, and
■
one half-height slot, slot 2).
—
—
The optional PCIe RAID controllers are all half-height. If you choose one of these cards in a
■
2-CPU configuration, only the full-height PCIe card slot will be available for an additional
optional PCIe card.
Note that only a single Cisco UCS 1225 Virtual Interface Card (VIC) card is supported and it
■
must be installed in the full-length, full-height PCIe slot (slot 1) on riser 1, which is the only
slot that supports NCSI. So take this into account when populating RAID controller cards.
You can choose only one type of RAID controller, either embedded RAID or a PCIe RAID
■
controller. If you choose embedded RAID, slot 1 in a 1-CPU system and slots 1 and 2 in a
2-CPU system are available for adding optional PCIe cards.
For PCIe RAID controllers, you can choose an optional RAID configuration (RAID 0, 1, 5, 6, or
■
10), which is preconfigured at the factory. The RAID level you choose must be an available
RAID choice for the controller selected. RAID levels 50 and 60 are supported, depending on
the RAID controller selected, although they are not available as configuration options.

Note that only a single Cisco 1225 Virtual Interface Card (VIC) card is supported and
it must be installed in the full-length, full-height PCIe slot (slot 1) on riser 1, which
is the only slot that supports NCSI. So take this into account when populating RAID
controller cards. You can have either a PCIe RAID controller or a VIC card in slot 1.
Slot 2 is not supported in 1-CPU systems.
If you choose embedded RAID, you can select up to two optional PCIe cards from
Table 8 on page 24 to be installed in slots 1 and 2.
If you choose a PCIe RAID controller from
slot 2 by default and you will be able to select one additional optional PCIe card
from Table 8 on page 24
NOTE: For more important information regarding RAID support, see
page 55 and RAID Option ROM (OPROM) Settings, page
Table 5 on page
to be installed in slot 1.
