Implementing Windows Server iSCSI
In this section, we will look at Internet Small Computer System Interface (iSCSI), which is pronounced as scuzzy (SKUZ-ee), like fuzzy.
What is iSCSI?
To set the scene, Small Computer System Interface (SCSI) is defined as a set of standards that connects and transfers data between computers and peripheral connected devices, such as disks.
iSCSI is a storage area network (SAN) technology protocol, and its communication with storage systems is done over Ethernet networks using TCP/IP. It emulates the local bus SCSI disk drive interconnect, making remote storage systems appear to the storage clients as local bus storage systems.
iSCSI is an alternative to the Fibre Channel (FC) and Fibre Channel over Ethernet (FCoE) protocol storage systems. iSCSI is cheaper and less complex to implement but has lower reliability and performance as the communications are sent using TCP/IP.
Now, let’s look at its components.
