The Hitachi storage systems provide heterogeneous connectivity to support multiple concurrent attachment to a variety of host operating systems, including UNIX, Windows, VMware, Linux, and mainframe servers, enabling massive consolidation and storage aggregation across disparate platforms. The storage systems are compatible with most Fibre Channel (FC) host bus adapters (HBAs), iSCSI adapters, and FC-over-Ethernet (FCoE) converged network adapters (CNAs).
