Then came iSCSI, which works with much cheaper Network Interface Cards (NICs), and can use regular network switches, as well us much cheaper copper cables. At first iSCSI wasn’t as fast as Fiber, topping out at gigabit speeds, so if speed was important, you’d stick with Fiber. Now with 10Gigabit Ethernet being readily available, you can get iSCSI SANs that are both cost effective and high performance.
