2.6 IBM Flex System V7000 Storage Node components
IBM Flex System V7000 Storage Node is an integrated entry / midrange virtualization RAID
storage to support and interface with the IBM Flex System. It brings with it the following
benefits:
Offers a single point of management for server, network, internal storage, and external
storage, virtualized by the integrated IBM Flex System V7000 Storage Node.
Gives improved access to critical data by keeping data close to the servers by minimizing
switch and cable hops.
Provides virtual servers fast shared storage access to better enable dynamic workload
assignments.
Moves the control of the virtual server storage over to the server administrators rather than
in the hands of the SAN administrators.
