There are multiple RAID options available for the Intel® Server Board S5000PSL.
Users must decide which RAID option is right for their usage and environment.
The following board models are available:
Each of these models have different storage controllers and capabilities:
- ESB2 SATA controller is on all models on the baseboard. It controls the black SATA ports.
- 1064e SAS Controller is only on the SAS model. It controls the 4 blue SAS ports on the motherboard.
- 1068 SAS Controller is only on the ROMB (RAID on Motherboard) Riser Card which ships with the ROMB model. It controls the 8 ports on the ROMB card and is independent of any ports on the motherboard itself.
All of the controllers are by default in non RAID mode and RAID must be enabled in the BIOS or by adding activation keys.
SAS controllers are capable of supporting either SAS or SATA drives.
These three controllers also offer RAID capabilities, which fall into two types:
- Embedded Server RAID Technology II (ESRT2), a firmware based RAID, available via BIOS setting on the ESB2 or 1064e controller.
- Intel® Integrated Server RAID (hardware RAID) available only on the 1068 controller when the optional RAID Activation key AXXRAK18E and RAM are added to the ROMB card.
ESRTII supports “software” RAID levels 0,1, or 10. You can expand this to support RAID level 5 by adding the software RAID 5 activation key (order code AXXRAKSW5). Both controllers that implement ESRT2 use the same driver available on the link below, even though one is a SATA RAID controller (ESB2) and the other a SAS/SATA RAID controller (1064e). The memory and processing power for this type of RAID comes from the main system board components.
The SAS ROMB Riser card by default acts as a SAS controller with 8 ports capable of supporting up to 120 devices. To activate RAID on this controller, you need to add a Hardware RAID Activation key and memory (in a mini DIMM format). With the RAID key and RAM added, this solution supports RAID levels 0, 1, 5, 10 or 50 and provides full hardware RAID functionality without using the system CPU or RAM.
|ESB2 SATA (ESRTII RAID)||1064 SAS (ESRTII RAID)||1068-based ROMB RAID|
|RAID levels supported||0,1,10 (5 with AXXRAKSW5 in SATA models)||0,1,10 (5 with AXXRAKSW5)||0,1,5,10,50 with AXXRAK18E MiniDIMM|
|RAID type||Uses system CPU and RAM||Uses system CPU and RAM||Has own RAM and processor|
|S5000PSLSATAR||6 onboard ports||n/a||n/a|
|S5000PSLSASR||2 onboard ports||4 onboard ports||n/a|
|S5000PSLROMBR||6 onboard ports||n/a||8 ports on ROMB Card|
Only the ROMB in hardware RAID mode can utilize the optional Intel® RAID Smart Battery Backup (RSBBU). The RSBBU provides battery power to keep the data in NVRAM viable during a system power loss, so that on power restore, the data can be written to the storage drive.
Important Note: RAID is not an alternative to a regular backup. Please backup data regularly to avoid data loss.
