The RAID controller is installed into dedicated PCI-E slot 4 (Figure 4). Simple Swap SATA models only
support the ServeRAID BR10il v2 controller. The BR10il v2 supports up to four SS SATA HDDs, and the
remaining two SATA HDDs can be used as standalone drives that are not part of a RAID array. Hot swap
SAS/SATA models do not support ServeRAID BR10il v2.
If the ServeRAID M5014 or M5014 controller is specified with a battery, it can be used in the x3755 M3.
However, the battery is installed separately on a remote battery tray and connected to the RAID controller
via the ServeRAID M5000 Series Battery Remote Mount Cable, 68Y7396. Installing the battery remotely
is done to avoid overheating. The remote battery tray is shipped standard with the server and is attached
to the side of the chassis.
The ServeRAID BR10il v2 SAS/SATA Controller has the following specifications:
One Mini-SAS internal connector
Supports RAID levels 0, 1, and 1E
3 Gbps throughput per port
Based on the LSI 1064E controller
PCI Express 2.0 x4 host interface
Stripe size: 64 KB (fixed)
