When setting up your EqualLogic storage systems to work in an ESXi implementation, you must address certain specific issues.

Follow these requirements:

  • You do not need any special multipathing setup. EqualLogic storage systems support storage-processor failover that is transparent to iSCSI. Multiple iSCSI HBAs or NICs can connect to the same target or LUN on the storage side. EqualLogic provides a multipathing extension module that can be installed on ESXi to provide additional capabilities.

    For information about the custom multipathing configuration packages, contact Dell EqualLogic.

  • Enable ARP redirection for ESXi hardware iSCSI HBAs. See Configuring Advanced Parameters for iSCSI.

  • EqualLogic storage systems impose a maximum limit of 1024 iSCSI connections per storage pool and 2048 connections per storage group.

  • Extend the iSCSI login timeout on the ESXi host to 15 - 30 seconds. See Configuring Advanced Parameters for iSCSI.

For more information about configuring and using EqualLogic storage systems, see the vendor’s documentation and the VMware knowledge base article at http://kb.vmware.com/kb/2007829.
