IBM 1814-70A server / storage / networking hardware Server Hardware / Parts

The IBM 1814-70A is a genuine IBM DS4700 storage array RAID controller, as stated directly in IBM’s own part description. The DS4700 was a mid-range Fibre Channel/SATA storage subsystem in IBM’s DS4000 series, and the 1814-70A controller manages RAID processing, host connectivity and cache for the array’s attached disk enclosures, presenting block storage LUNs to connected servers over Fibre Channel. DS4700 arrays of this generation were widely deployed as consolidated SAN storage for mid-sized server estates during the mid-to-late 2000s, and while IBM’s storage line has moved on to newer DS8000/Storwize/FlashSystem platforms since, DS4700 arrays remain in service at sites that have not yet migrated, where a genuine controller replacement restores full redundancy or capacity after a fault. Buyers should confirm firmware level and dual-controller configuration compatibility before ordering, since DS4700 controllers must typically match their paired unit’s firmware revision.
