Re: 5737 Raid card

[Pat Barber <mboceanside@xxxxxxxxxxxxxxxx>]

You did noy say what machine you were putting it in but
the 9406-520 Sales manual entry comes up with this:

#5737) - PCI-X Disk Ctlr-90MB w/IOP

Provides a PCI-X SCSI disk controller that has a 90MB write cache and 
can provide RAID-5 or RAID-6 protection of disk units.

The #5737 has two U320 SCSI buses each with a bus data rate of up to 
320MBs. A maximum of 12 internal disk drives and up to two internal 
removable media devices (tape, CD-ROM, DVD-ROM, or DVD-RAM) are 
supported on the #5737.

A minimum of three disk drives are required for RAID-5, providing 
protection against a single drive failure in an array. A minimum of four 
disk drives are required for RAID-6, providing protection against up to 
two drives failing in an array.

#0648, #5737, and #5776 are physically the same adapter card but have 
different feature numbers to indicate to IBM configurator tools that an 
IOP is or is not being used in the configuration.

Note the #2780/#5580 and #2757/#5581 disk controllers with an effective 
757MB write cache provide greater disk performance and can have an 
auxiliary write cache IOA to protect the write cache contents.

    * Attributes provided: Two U320 SCSI VHDCI ports
    * Attributes required: One available 3.3V long PCI or PCI-X slot
    * For 9405 - 520 (5737)
          o Minimum required: 0
          o Maximum allowed: 31 (Initial order maximum: 0 )
          o OS level required: i5/OS V5R3, or later
          o Initial Order/MES/Both/Supported: MES
          o CSU: Yes
