Direct connect
NOTE:
Direct connect is currently supported on Microsoft Windows only. Refer to the HP StorageWorks
Enterprise Virtual Array 4000/6000/8000 release notes for more information on direct connect support.
Direct connect provides a lower cost solution for smaller configurations. When using direct connect, the
storage system controllers are connected directly to the host(s), not to SAN Fibre Channel switches. Make
sure the following requirements are met when configuring your environment for direct connect:
• A Windows host running HP Command View EVA must be connected to one port on each EVA
controller. The management host must use dual HBAs for redundancy.
• To provide redundancy, it is recommended that dual HBAs be used for each additional host
connected to the storage system. Using this configuration, up to four hosts (including the
management host) can be connected to an EVA8000, and up to two hosts can be connected to
an EVA6000 or EVA4000.
• The Host Port Configuration must be set to Direct Connect using the OCP.
• HP Continuous Access cannot be used with direct connect configurations.
