4. How to Utilize LSI Controllers
When configuring any of the new P500/P510, P700/P710, or P900/P910 platforms with one of the
optional LSI controllers, there are some considerations to be made in order to ensure all the necessary
hardware is installed to support these controllers. Both the LSI SAS/SATA FLEX RAID Adapter and the LSI
9364-8i ROC controller can utilize BCA's or manual cable connections. Note that if manual connections
are used, a maximum of 4 drives can be supported in the system.
For P900/P910, two BCA-S assemblies are standard to the system, so no additional hardware is required
other than the optional LSI controller (FLEX RAID Adapter or 9364-8i). Alternatively, BCA-P can also be
used in place of BCA-S with the same functionality.
For P500/P510 and P700/P710, the normal method supporting drives with the LSI controllers is by BCA.
Manual cable connections can be used, but this also limits the maximum number of drives supported to
4 total drives.
With either of the LSI controllers installed, each platform can support a maximum of 8 drives when
BCA's are utilized. Once the BCA is connected properly to the controller and AC power is applied, the
BCA will illuminate LEDs near each port to show that it is active and the drive types that can be
supported (SATA and SAS). With the use of manual cable connections, the maximum number of drives is
limited to 4 per system.
