The ASP R6.0.x 100 Series server FRUs, based on Dell R640 and R660xs platforms, are shipped with different default configurations. The R640 server FRU includes a single HDD and does not have a RAID array preconfigured. In contrast, the R660xs server FRUs are delivered fully populated with HDDs, with the RAID array configured by default. An exception to this is the A31 configuration, which utilizes the A3 server FRU. For A31 deployments, two HDDs must be added, and the RAID array manually reconfigured prior to software installation.
