The IBM DS5000 Series storage systems are the of mid-tier storage systems from IBM. The DS5000 Series consists of multiple models and disk only modules for expandability to meet the storage requirements for open systems and System-i platforms. Models available in the DS5000 series include the DS5100, DS5300, and DS5020 Express.
Competitive multi-platform distributed storage hardware systems include alternatives such as EMC’s VNX series, Hitachi Data System (HDS) Hitachi Unified Storage (HUS) Series, and Hewlett Packard’s (HP) 3PAR StoreServ 7000 series.
The DS5000 Series of storage systems represent the continuation of the hardware evolution of the systems developed by NetApp Engenio and offered by IBM in their midrange disk lineup. The architecture with custom hardware implementation uses ASICs and embedded software.
IBM has continued to provide the high performance systems as their midrange systems line with additions and upgrades to the product line. With the DS5000 Series, there are three models to provide different price/performance points for customers.
