The ETERNUS DX8700 S2 enterprise disk storage system, with Intel® Xeon® processors is purpose-built for large enterprises. Enterprises are no longer forced to anticipate future capacity demand levels and to select a specific high-end model with limited data-capacity range. The unique modular architecture offers flexibly scaling according to business needs. With minimum initial costs customers can start with a two controller module system and four drive enclosures. Maximum performance with up to 128 front-end host ports can be obtained by scaling up to eight controller modules. FC, FCoE and iSCSI host interfaces can operate in mixed configurations.
