3.9.5 Dedicated controller slot
As listed in Table 3-27 on page 96, certain supported controllers (including the ServeRAID
BR10i that is standard in most models) can be installed in a single PCIe x8 dedicated slot on
the side of the server, near the front. Figure 3-25 on page 101 shows the ServeRAID M5015
adapter installed on the side of the server, near the front with an installation bracket attached
(blue plastic handle).
The blue plastic carrier is reusable and is included with the server (attached to the standard
BR10i). The latch and edge clips allow the card to be removed and replaced with another
supported card as required.
Important: Two variants of the 6Gb Host Bus Adapter exist. The SSD variant has no
external port and is part number 46M0914. Do not confuse it with the IBM 6Gb SAS HBA,
part number 46M0907, which is not supported for use with eXFlash.
Important: This controller is listed in power-on self test (POST) and in UEFI as a
PMC-Sierra card. This controller uses the maxRAID Storage Manager for management,
not MegaRAID.
