Isilon scale-out NAS systems lean heavily on DNS. DNS plays a vital role in the way the clients access the files on the Isilon cluster: clients are distributed across nodes and network interfaces based on what your DNS reports back to the clients. This is all done by the SmartConnect component in the Isilon which is configurable up to a certain extent. In this post I’ll explain what SmartConnect does and will also share a tip to speed up your Isilon DR procedure.
Yesterday we racked and stacked the EMC Isilon systems, prepared most of the cabling and pretty much prepared to start the Isilon systems. Which is pretty uneventful if you consider we’ve been dragging along hundreds of kilograms of equipment all day yesterday… The whole process can be pretty much split in four parts: configure the cluster and initial node, join the remaining nodes, configure the network, configure the rest.
