The first image defines what is iSCSI and what exactly its role is, in Storage Area Networks. Convergence is happening over IP everywhere (one reason why IP is exciting!), and even the Storage Area Network is expected to converge over IP networks through iSCSI especially with the anticipation of lossless Converged Enhanced Ethernet. The other popular option being FCOE (Fiber Channel Over Ethernet).
This article is to give and introduction to the technologies that are up against each other to provide high performance computing. We look at Ethernet, Fiber channel, Infiniband and the various consolidations that are proposed. We also take a peek at iSCSI.
