The K2R84A is the HPE MSA 2040 Energy Star SAS Dual Controller SFF Storage array, a 2U small form factor storage system with two MSA 2040 SAS controllers. It comes as an SFF array chassis with both controllers installed; no drives or host connect cables are included, and SFPs are not required for SAS controllers. The K2R84A is the Energy Star SKU that replaces C8S55A.
The chassis has 24 small form factor drive bays for SSD, SAS, self-encrypting and SAS midline drives. Each SAS controller has four 6Gb/12Gb mini-SAS HD host ports, giving eight host ports per array, and each controller carries 6 GB of cache, of which 4 GB is read/write data cache. Cache backup is battery-free, using super capacitors and compact flash.
The MSA 2040 includes 64 snapshots as standard, with an optional 512-snapshot license, and supports thin provisioning and RAID levels 1, 5, 6 and 10. The array grows with up to seven disk enclosures, either D2700 SFF enclosures or MSA 2040 LFF enclosures, to a maximum of 199 small form factor drives.
Related MSA 2040 parts include the K2R80A SAN dual controller SFF array, the C8S53A MSA 2040 SAS controller and the K2R82A LFF chassis. More arrays are in HPE storage systems.
