Controllers for Internal Drives
Note that if the following Cisco 12G SAS Modular RAID controller or Cisco 12Gbps Modular SAS HBA

controller is selected, it is factory-installed in the dedicated internal slot.
UCSC-MRAID12G

Cisco 12G SAS Modular RAID Controller

■

Supports up to 24 internal SAS HDDs and SAS/SATA SSDs

(limited to 12 drives in this server)

■

Supports JBOD, RAID 0, 1, 10 (with no FBWC option chosen) and has the

ability to also support RAID 5, 6 if a Flash-Backed Write cache upgrade is

chosen (shown below in this table)

■

SED drives are compatible with only with the combination of a

UCSC-MRAID12G RAID controller along with one of the flash-back write

cache modules (UCSC-MRAID12G-1GB, UCSC-MRAID12G-2GB, or

UCSC-MRAID12G-4GB).

■

For all self-encrypting drives (SED), standalone Management (CIMC) is

supported for configuring and managing local keys (UCSM is not

supported). For now, SED drives are managed with local key management

only. In the future, third-party key management will be supported.

UCSC-SAS12GHBA

Cisco 12 Gbps Modular SAS HBA

■

Supports up to 24 internal SAS HDDs and SAS/SATA SSDs

(limited to 12 drives in this server)

■

Supports JBOD mode only (no RAID functionality. Ideal for SDS (Software

Defined Storage) applications. It is also ideal for environments demanding

the highest IOPs (for external SSD attach), where a RAID controller can be

an I/O bottleneck.

UCSC-PSAS12GHBA

Cisco 12 Gbps Modular SAS HBA

■

Supports up to 24 internal SAS HDDs and SAS/SATA SSDs

(limited to 12 drives in this server)

■

Supports JBOD mode only (no RAID functionality. Ideal for SDS (Software

Defined Storage) applications. It is also ideal for environments demanding

the highest IOPs (for external SSD attach), where a RAID controller can be

an I/O bottleneck.

■

Same functionality as UCSC-SAS12GHBA, but vendor is Microsemi
