Storage Replica - MSA - 3PAR disk choise

    Question

  • Hello,
    I have a project where i need to have storage replication between a MSA P2000 and 3PAR. As MSA does not support SSD disks i am not sure of the replication might have issues or lateness while performing. Normally there should be 2 VDisks, one ofr Data and one for LOG. The LOG one apparently is demanded to be a SSD media of a minimal size of 9GB.
    Please may someone suggest if i can declare the SAS on P2000 as a SSD VDISK without having problems? What might be the problems in that case anyway?
    Thank you

  • Hi Sir,

    >> The LOG one apparently is demanded to be a SSD media of a minimal size of 9GB.

    Yes , LOG disk should be SSD which providing high performance . 

    As we know SSD would provide higher I/O than SAS .

    But it should work in your environment (might not experience high performance as you expected ) ,if the disk configuration meet the requirement below:

    In addition , I had successfully built a lab with only iSCSI disks for storage replication .
