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 management server 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 EVA8x00, and up to two hosts can be connected
to an EVA6x00 or EVA4x00.
• The Host Port Configuration must be set to Direct Connect using the OCP.
• HP Continuous Access EVA cannot be used with direct connect configurations.
• The HSV controller firmware cannot differentiate between an empty host port and a failed
host port in a direct connect configuration. As a result, the Connection state dialog box on
the Controller Properties window displays Connection failed for an empty host port. To fix this
problem, insert an optical loop-back connector into the empty host port; the Connection state
will display Connected. For more information about optical loop-back connectors, contact
your HP-authorized service provider.
