MultiStore is an optional software product that enables you to partition the storage and network resources of a single filer so that it appears as multiple filers on the network. Each "filer" created as a result of the partitioning is called a vFiler unit. A vFiler, using the resources assigned, delivers file services to its clients as a filer does.
The storage resource assigned to a vFiler can be one or more qtrees or volumes. The network resource assigned can be one or more base IP addresses or IP aliases associated with network interfaces. You can add or remove resources at any time.
You can create up to 32 vFiler units on a filer or 64 in a cluster.
