History

Originally, in 1998 IBM released the IBM 2105 Versatile Storage Server (VSS).^[1] It did not meet commercial success and the successor came in 1999^[2] in the form of the ESS, based on the same Seascape architecture. The Seascape architecture was an IBM storage architecture that included off-the-shelf components, including RS/6000 processors and the Serial Storage Architecture (SSA). The ESS was also widely known by its IBM internal codename Shark.

The 2001 lineup have a redesigned case; this version won IF design award.^[3]

It has been superseded by the IBM DS8000 series of storage servers.
