IBM Blade JS12 Express. AIX 5.3

Hello everyone,  ( I know of one using blades for HL7 are there others? )

How many others are running cloverleaf on a blade.  With the JS12 one can have 2 10K drives mirrored. Issue here is the 10K drives not 15K.  How much of an issue?

Yes I know one can use SAN, but we are not there yet.

Also on the JS12 the Processor is a dual core, will cloverleaf make use of them?

Thanks for any information.

James
