I'm upgrading a customer with <100 users from the ICS7750 to an MCS platform. They only need 100 users so the 7825 is the right size. However, they want scsi raid(1). The 7825 with scsi raid is specified to be used only for Unity. Can anyone tell me if the scsi raid platform(MCS-7825H-3.0-ECS1) can be used for Callmanager instead of Unity.
