K2R83A HPE MSA 2040 Energy Star SAS Dual Controller LFF Storage

The K2R83A is the HPE MSA 2040 Energy Star SAS Dual Controller LFF Storage array. It includes the LFF array chassis with two MSA 2040 SAS controllers installed. Drives and host connect cables are not included, and SFPs are not required for SAS controllers. The 2U chassis has 12 large form factor drive bays and takes SAS, self-encrypting and SAS Midline drives.

Each SAS controller has four 12Gb mini-SAS HD host ports (SFF-8644) and accepts 6Gb and 12Gb SAS host connections, with 4GB of read/write cache per controller that has ECC protection and backs up to flash memory. RAID levels 0, 1, 3, 5, 6, 10 and 50 are supported. The chassis weighs 31 lb without controllers and measures 3.5 in (8.9 cm) high, 17.6 in (44.7 cm) wide and 22.5 in (57.2 cm) deep from the ear to the controller handle.

Up to 7 disk enclosures can be added, which grows the array to 96 LFF drives. The M0S96A MSA 2040 LFF Disk Enclosure attaches to this array, as does the MSA 2050 LFF Disk Enclosure Q1J06A with GL225 controller firmware or later, and each ships with two 0.5m mini-SAS cables for the expansion port. 12Gb SAS hosts connect with the 1m 716195-B21, 2m 716197-B21 or 4m 716199-B21 mini-SAS HD cable.

SAS host connections run from adapters such as the H241 12Gb 2-ports Ext Smart Host Bus Adapter 726911-B21 and the Smart Array P441 726825-B21 and P431 698531-B21 controllers, and the BK763A and BK764A 6Gb SAS switches serve BladeSystem c-Class. K2R83A takes over from the C8S54A SKU with no physical, form, fit or function difference. The SFF model with the same SAS controllers is the K2R84A MSA 2040 SAS Dual Controller SFF Storage, and other MSA arrays and enclosures are collected in the HPE storage systems category.
