Both iSCSI and NFS are storage solutions that can leverage the existing TCP/IP network infrastructure. Hence, they are referred to as IP-based storage. Before we start learning how to configure them, let's delve into some iSCSI and NFS fundamentals.
Introduction
iSCSI fundamentals
The Internet Small Computer Systems Interface (iSCSI) is a protocol used to transport SCSI commands over a TCP/IP network. In an iSCSI environment, the client machine (in this case, an ESXi host) uses iSCSI initiators (hardware/software) to connect to iSCSI targets on an iSCSI storage system.
Let's review some of the iSCSI terminology that you will need to be aware of before you learn how to configure and manage access to iSCSI storage...
