IBM Enterprise Storage Server

The IBM Enterprise Storage Server (ESS) or the Shark is an enterprise storage array from IBM.

History
Originally, in 1998 IBM released the IBM 2105 Versatile Storage Server (VSS). It did not meet commercial success and the successor came in 1999 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.

It has been superseded by the IBM DS8000 series of storage servers.
