If you are planning to do a field upgrade to add a RAID adapter or HBA for connectivity to the drives, you will need to order the RAID/HBA Cable & Flash Module Mechanical Kit, 4Z57A14087. This kit contains the cable which connects the adapter to the four SATA drives, replacing the existing four SATA cables. For the RAID 930-8i adapter, the kit also contains the bracket for the RAID adapter's flash power module. For CTO and preconfigured models in the configurator tool, the cable and flash power module bracket are automatically added if needed.
