Iscsi Connection Configurations; Fabric Connect Iscsi; Direct Connect Iscsi - HP 6100 User Manual

iSCSI connection configurations

The EVA4x00/6x00/8x00 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:
A maximum two MPX100s per storage system are supported.
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 Direct Connect using the OCP.
HP Continuous Access EVA cannot be used with direct connect configurations.
EVAs cannot be directly connected to each other to create HP Continuous Access EVA
configuration. However, hosts can be direct connected to the EVA in a HP Continuous Access
configuration. At least one port from each array in an HP Continuous Access EVA configuration
must be connected to a Fabric connection for remote array connectivity.
