IsilonSD cluster overview

An IsilonSD cluster consists of three to six virtual nodes hosted on VMware ESXi. Each virtual node runs the Isilon OneFS operating system, the distributed file-system software that unites the nodes into a cluster.

The cluster's storage capacity varies depending on the following factors:

IsilonSD license type
Minimum data disk size
Minimum number of data disks per node
Number of nodes in the cluster
