MSA20 cache upgrade from standard 128mb?

[David Calabro]

I have a MSA20 disk array with the standard 128mb cache module.

Will it accept a 256mb cache module?

No, it's clearly stated on the MSA20 quickspecs:

Controller Cache:

Cache on the Modular Smart Array 20 Controller may not be upgraded. It
comes standard with 128 MB of battery-backed cache.

NOTE: The Modular Smart Array 20 Controller allows the following cache
configurations: 1 x 128 MB

Thanks for the quick reply!

It doesn't support it seeing that it uses the same modules as the SA6400 series. A 256 or 512mb would have been nice!
