RAID Volumes and Groups
When creating each RAID volume, follow these guidelines:
■
Use the same capacity for each drive in each RAID volume
■
For embedded software RAID or the embedded software RAID 5 key upgrade:
— Use only SATA HDDs
— Embedded software RAID has two ports and each port can control 4 drives, for 8
drives total.
— Each set of 4 SATA HDDs for a port must be in separate RAID volumes.
— You cannot mix drives across ports to create a RAID volume.
— For more details, see
.
■
For the Cisco 12G SAS modular RAID controller upgrade:
— Use either all SAS HDDs, all SAS SSDs, or all SATA SSDs in each RAID volume
The number of RAID groups (virtual drives) supported per RAID controller is as follows:
■
Embedded RAID = 8
■
Cisco 12G SAS Modular RAID controller = 64
Select Controller Options
Select one of the following:
■
Embedded software RAID (this is the default if no other selection is made), or
■
Embedded software RAID 5 key upgrade option for internal drives (see
or
■
One Cisco 12G SAS modular RAID controller or Cisco 12 Gbps Modular SAS HBA (see
), or
■
Mixed controllers:
— One Cisco 12G SAS modular RAID controller or one Cisco 12 Gbps Modular SAS HBA
and
— One or two Cisco 9300-8E 12G SAS HBAs for external SAS JBOD/enclosure
connectivity support
NOTE: Mixing the Cisco 9300-8e HBA in the same server as the Cisco 12 Gbps
Modular SAS HBA requires the following firmware levels:
Modular SAS HBA requires the following firmware levels:
■
Cisco IMC/BIOS 2.0(8) or later
