HP Smart Array 6400 Series Controllers Support Guide, September 2007

Board Components and Features
The Smart Array 6402 Series Controller has two Ultra320 SCSI channels and 192 MB of cache,
128 MB in the cache module and 64 MB on the board.
The Smart Array 6404 Series Controller has two controllers. Each controller has two Ultra320
SCSI channels and 256MB of cache, 128MB in the cache module and 64MB on each controller.
CAUTION: The Smart Array Controllers have two (6402) or four (6404) channels. There are two
channels on the 6402 base controller, each having one internal and one external connector. One
connector can be used per channel at any given time. If both the internal and external connectors
on the same channel are connected to the Itanium platform and boot is attempted, the following
message displays:
1783 - Drive Array Controller Failure!
[Controller self-test failure (failure code = 0093]
Until this problem is fixed, the controller will not be available upon boot. If the system is booted,
the Smart Array locks up.
NOTE: Booting from channels B1 and B2 of the Smart Array 6404 Series Controller is not
supported.
