vSphere StorageHP StorageWorks SAN/iQ Storage SystemsHP StorageWorks (formerly LeftHand) SAN/iQ systems support ESXi iSCSI connections from a softwareinitiator and hardware initiator.When configuring SAN/iQ, enable automatic volume resignaturing for SAN/iQ storage devices to allowaccess to SAN/iQ snapshots and remote copies.For more information on configuring HP StorageWorks storage for VMware vSphere, see the vendordocumentation related to VMware.Basic configuration steps include several tasks.1 Install SAN/iQ storage nodes.2 Create SAN/iQ management groups and clusters.3 Create volumes.4 Assign volumes to authentication groups and volume lists.5 Enable ARP redirection on hardware iSCSI HBAs.As a best practice, configure virtual IP load balancing in SAN/iQ for all ESXi authentication groups.Dell PowerVault MD3000i Storage SystemsWhen you configure mutual CHAP for the MD3000i iSCSI storage systems, special considerations thatapply.When you configure mutual CHAP for the MD3000i iSCSI array, follow these guidelines:• On the MD3000i storage system, mutual CHAP configuration requires only a CHAP secret.• On the ESXi host, mutual CHAP configuration requires both the name and CHAP secret. Whenconfiguring mutual CHAP on the ESXi host, enter the IQN name of the target as the mutual CHAPname. Make sure the CHAP secret matches the one set on the array.iSCSI Targets in vAppsIf you use an iSCSI target in a virtual appliance, for example HP LeftHand P4000 VSA, the host shouldconnect to the target through the software iSCSI adapter rather than a hardware iSCSI adapter.106 VMware, Inc.
