K2R84A HPE Msa 2040 Es SAS Storage Array Dual Controller SFF

HPE MSA enterprise storage array component — controller / drive / shelf / battery / cache / power / I/O / cable / DAE component for HPE MSA SAN/NAS infrastructure.

Specifications

• Part Number: K2R84A
• Brand: HPE
• Component: See item_group (Controller / Storage Drive / Drive Enclosure / DAE Component / Battery / Cache Module / Power Supply / I/O Module / Cable / Bezel / Shelf / Boot Drive)
• Capacity / Speed: See PN
• Interface: SAS-3 12G / SAS-4 24G / NVMe / FC 16G/32G/64G — see PN
• Form Factor: SBB carrier / SFF 2.5" / LFF 3.5" / dual-controller pair — see array model

Compatibility

HPE MSA storage-array components are tightly array-model-keyed. SBB carriers are NOT interchangeable with server-side carriers. Controllers must be paired (active/active or active/standby) for HA.

• Controller pair-match required: firmware mismatch on swap triggers HA degradation
• Drive SBB carriers: array-specific PN (3PAR / MSA / Alletra / Dell EMC / Lenovo DE/DS use different carriers)
• Cache module / battery: protects write-back cache on power loss — required PN match per controller revision
• Drive enclosure / shelf: capacity expansion via SAS expansion to controller; verify SAS speed (6G/12G/24G) match
• I/O Module / FC port / iSCSI port: hot-pluggable on most enterprise arrays — exact PN per controller gen

Use Cases

Production SAN / NAS storage spare-parts for Tier-1 enterprise arrays. Dual-controller active/active HA design provides non-disruptive controller swap. SBB drive carriers + drive enclosures expand capacity online. Cache modules + flash-backed batteries protect in-flight write data. Hot-pluggable I/O modules add FC / iSCSI / Ethernet ports without downtime. Critical for VMware / Hyper-V / SQL Server / Oracle / SAP HANA production deployments.
