Booting any operating system from the ServeRAID card will not be supported.
IBM Fibre Array Storage Technology
The IBM Fibre Array Storage Technology (FAStT) family of Fibre Channel storage
solutions is designed for high-availability, high-capacity requirements. FAStT
solutions can support transfers over distances up to 10 km (6.2 miles) at rates of
up to 200 MBps.
The FAStT Storage Server is a RAID controller device that contains Fibre
Channel (FC) interfaces to connect the host systems and the disk drive
enclosures. The Storage Server provides high system availability through the use
of hot-swappable and redundant components. We briefly discuss the following
three products:
The IBM TotalStorage™ FAStT200 Storage Server
The IBM TotalStorage FAStT500 Storage Server
The IBM TotalStorage FAStT700 Storage Server
Note: The FAStT700 is currently the only certified storage solution for
Microsoft clustered configurations. To check the Microsoft Hardware
Compatibility List (HCL) for updates to certified solutions, refer to

The IBM TotalStorage FAStT200 Storage Server
The FAStT200 Storage Server is a 3U rack-mountable Fibre Channel RAID
controller and disk drive enclosure. It targets the entry and midrange segment of
the FC storage market. A typical use of the FAStT200 would be in a two-node
cluster environment with up to 66 Fibre Channel disk drives attached to the
Storage Server.
Two models are available:
The FAStT200 Storage Server, with a single RAID controller.
The FAStT200 High Availability (HA) Storage Server, which contains two
RAID controllers and can therefore provide higher availability.
Both models feature hot-swap and redundant power supplies and fans and you
can install up to 10 slim-line or half-high FC disk drives. If you need to connect
more than 10 disks, you can use the EXP500 FC storage expansion enclosures.
Each EXP500 can accommodate 10 additional disk drives, and up to five
EXP500s are supported on the FAStT200. This means that the maximum
supported number of disk drives is 60.
