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.
