Yes... call your IBM guy and tell him you need battery-backed 512MB cache module because yours is faulty... you may be able to finagle a free one!

Well, my IBM guys keeps telling me, that maximum cache size for this controller is 256 MB. But I'm not sure if I can believe him. Do you have this controller with 512 MB cache module ? Do you know what is the part number for this module ?

Yes you can believe him, not because he is a ibm guy.

Check the specs of the serveraid 6m at the following links

ftp://ftp.software.ibm.com/pc/pccbbs/pc_servers_pdf/srad6spc.pdf

There are only two options
128MB - 32P0033(part no)
256MB- 02R0988 (part no)

I hope that 256MB would be enough for your raid controller. Adding too much memory may not help in increasing the performance.
