    Removal of SAS R5 from RSTe....does ESRT2 EFI Boot?




      I had previously offered the RKSAS4R5 as a software RAID 5 option for SAS disks.  RSTe has been the preferred configuration because firstly it supports EFI boot and secondly I could pre-install the console to manage the RAID array.  One downside was that I couldn't designate a hot spare in the RSTe BIOS utility and had to wait until I had the console installed on the OS, yes I know CLi exists but it's too much hardship for me.


      I was disappointed to see that in the latest RSTe driver/BIOS that SAS R5 has been removed so previously where the RKSAS4R5 would operate in both RSTs and ESRT2 mode it will now work in ESRT2 mode only.


      A few questions as a result.


      1. Why was SAS R5 removed from RSTe driver
      2. Will SAS R5 support be added back at a later date?
      3. Can current implementations of ESRT2 allow EFI BOOT?
      4. Is ESRT2 performance below par when compared to RSTe
      5. We build servers for resellers and I understand that the Intel RAID Web console cannot be pre-installed from a Windows Server audit boot environment because firstly an administrator password is required and secondly if the reseller changes the default server name (100% likely) the installation no longer works.Is my understanding correct or can Intel RAID Web Console 2 be pre-installed?


      Of course one advantage to using ESRT2 is that I can pre designate a hot spare in the BIOS setup.  Why can hot spares not be designated in the BIOS pages for the RSTe?








      Known Restrictions


      1. SAS features are enabled on SATA/SAS Capable Controller if appropriate Intel(R) RAID C600 Upgrade Key is present in the system.

      2. RAID 5 is no longer supported by SATA/SAS Capable Controller when SAS features are enabled.
