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.
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?
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.
1&2. SAS RAID 5 on RSTe is never supported, and is not likely to be added. See http://www.intel.com/support/motherboards/server/sb/CS-033461.htm Intel® RAID Quick Reference Guide.
3. Unfortunately no.
4. I don't think there is a big difference in performance between RSTe and ESRT2.
5. I don't think changing the server name would impact RWC2. RWC2 discovers servers by IP address.
Thanks for reply is there a way to install RWC2 in audit mode of Windows server (2008/2012/2012R2) where the admin account does not yet have a password?
I know that silent install is available using the command:
Setup.exe /s /v"/qn SETUPTYPE=
where setuptype may be StandAlone, Client or Server.
But I don't know if it will work or not before setting admin password.
