On today’s episode the Datanauts turn their powerful telescopes on the iSCSI storage protocol. Proponents of iSCSI tout its wide support among storage vendors and in OSs, and that, because it runs over Ethernet, iSCSI benefits from the network protocol’s gains in throughput.
Chris Wahl and Ethan Banks are joined by Andy Banta, storage janitor and principle virtualization architect at NetApp SolidFire, to get into the nitty gritty of iSCSI and explore its good sides and bad sides, particularly in the context of highly virtualized environments. (Chris has a few bones to pick with iSCSI and vSphere.)
They also delve into why network architecture makes a significant difference in iSCSI performance, and see how iSCSI compares to other options such as Fibre Channel.
