How to setup a SAN cluster by configuring target portals?

SAN clusters share storage resources and enhance efficiency and cost effectiveness. Clustering SAN appliances also improves data availability. By clustering SAN appliances, a number of challenges are easily overcome. StoneFly’s SCVM™ software facilitates SAN clustering via target portals.

Target Portals are an iSCSI term for a communications portal between two iSCSI devices. This article is meant to guide you through the setup process of target portals in order to configure a SAN cluster between two SAN appliances.
