Why Am I Not Able to Configure ESRT2 RAID 5 with SAS HDD on Intel® Server System R2000WF?

What is the correct way to properly setup ESRT2 RAID 5 with SAS HDD on Purley platforms such as the server system R1000WF, server node HNS2600BP, server board S2600ST?

Make sure you meet the following hardware requirements:

1. Use Intel® RAID C600 Upgrade Keys
2. HSBP (Hot Swap Backplane)
   1. For R2000WF Product Family & R1000WF Product family - check the Intel S2600WF Product Family Configuration Guide page137 & 138 to find the compatible HSBP.
   2. For S2600ST Product Family - check the Intel S2600ST Product Family Configuration Guide page 40 to find the compatible HSBP.
3. Bridge Board
   1. For HNS2600BP Product Family, check the Intel® S2600BP Product Family Configuration Guide page 58 & 59 to find the compatible bridge board.
   2. Note: Intel® RAID C600 Upgrade Keys is not needed if the bridge board supports both SAS HDD and RAID 5.
