Serial Storage Architecture (SSA) was a serial transport protocol used to attach disk drives to server computers. It was developed by IBM employee Ian Judd in 1990 to provide data redundancy for critical applications.

The Social Security Administration (SSA) operated the IBM Collater, and a variety of other mechancial card-punch and tabulating devices, throughout the 1930s and 40s. In 1950, SSA deployed its first electronic computing device, an IBM 604 Electronic Calculator, which was used to do benefit computations.

On September 16, 1936, IBM won the contract and quickly unveiled a technological workhorse developed specifically for the SSA: the IBM 077 Collator, a massive machine for reading and organizing punched cards into a single pile.

The IBM SSA RAID Adapter for PC Servers is a Peripheral Component Interconnect (PCI) bus-master adapter that is used as the interface between systems that are using the PCI architecture, and devices that are using the Serial Storage Architecture (SSA). The adapter provides four SSA ports for the attachment of storage devices such as hard disk ...

A qualified SSA includes the field value for DL/I to search for a segment occurrence. In other words a qualified SSA specifies a particular segment occurrence based on a condition that a field within a segment must meet.
