OnStor Inc.'s and 3PAR Inc.'s UtiliCat: UtiliCat, a bundle that features

OnStor's Bobcat series NAS gateway with 3PAR's InServ FC storage

system, blurs the line between a NAS gateway and an integrated NAS file

system. (OnStor recently integrated its product with Xiotech's Magnitude

array.) UtiliCat can also attach to other vendors' FC storage, acting as a

NAS gateway. In addition, it can support up to 384TB of NAS storage.

Rather than offering both file and block access through one system like

NetApp and others, UtiliCat's block access goes directly to back-end

storage and bypasses the filer altogether. Furthermore, both the filer front

end and back-end storage can be expanded transparently to client access,

which makes storage provisioning easier.

Bobcat's nodes act as a cluster providing file access to the shared back-

end storage. Up to eight Bobcat nodes can be clustered, and any node can

access any storage. File systems can be updated a node at a time, but can

be read by multiple nodes. In case of a failure, any active node can pick up

the file services of the failing node.

UtiliCat provides snapshot, asynchronous local data mirroring, virtual

servers and full Network Data Management Protocol (NDMP) support.

Remote data mirroring can be added using SAN extenders. Virtual servers

represent a partitioning of the file server into multiple, logical file-server

gateways, each of which can be managed as a separate entity. For those

clients who grew up managing their own file servers, a virtual server can

provide a way to physically consolidate storage to one file server but

logically still allow the client to manage their file system separately for

physical consolidation. Up to 40 virtual servers can be configured across

the eight-node cluster. A virtual server can be easily moved from one

Bobcat node to another to better balance performance and/or workload

requirements.
