Iscsi Connection Configurations; Fabric Connect Iscsi; Direct Connect Iscsi - HP StorageWorks 6400/8400 - Enterprise Virtual Array User Manual

• To provide redundancy, it is recommended that dual HBAs be used for each additional host con-
nected to the storage system. Using this configuration, up to four hosts (including the management
host) can be connected to an EVA6400/8400.
• 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.

iSCSI connection configurations

The EVA6400/8400 support iSCSI attach configurations using the HP MPX100. Both fabric connect
and direct connect are supported for iSCSI configurations. For complete information on iSCSI
configurations, go to the following website:
http://h18006.www1.hp.com/products/storageworks/evaiscsiconnect/index.html
NOTE:
An iSCSI connection configuration supports mixed direct connect and fabric connect.

Fabric connect iSCSI

Fabric connect provides an iSCSI solution for EVA Fibre Channel configurations that want to continue
to use all EVA ports on FC or if the EVA is also used for HP Continuous Access EVA.
Make sure the following requirements are met when configuring your MPX100 environment for fabric
connect:
• A maximum of two MPX100s per storage system are supported
• Each storage system port can connect to a maximum of two MPX100 FC ports.
• Each MPX100 FC port can connect to a maximum of one storage system port.
• In a single MPX100 configuration, if both MPX100 FC ports are used, each port must be connected
to one storage system controller.
• In a dual MPX100 configuration, at least one FC port from each MPX100 must be connected to
one storage system controller.
• The Host Port Configuration must be set to Fabric Connect using the OCP.
• HP Continuous Access EVA is supported on the same storage system connected in MPX100 fabric
connect configurations.

Direct connect iSCSI

Direct connect provides a lower cost solution for configurations that want to dedicate controller ports
to iSCSI I/O. When using direct connect, the storage system controllers are connected directly to the
MPX100(s), not to SAN Fibre Channel switches.
Make sure the following requirements are met when configuring your MPX100 environment for direct
connect:
