Acopia Talks Snapshots

Acopia Networks says it's able to take file snapshots from a virtualized volume spanning EMC and NetApp NAS arrays. (See Acopia Snaps Across EMC NAS.)

But don't reach for the phone just yet.

"We plan a product in the future. We do have customers using this in a beta-like mode," says Kirby Wadsworth, SVP of marketing and business development at Acopia. But for now, he admits the feat he's describing is just a "shot across the bow."

Acopia's in-band ARX switch, positioned between servers and NAS systems, creates a global namespace for multivendor NAS boxes. (See Acopia Files Away $20M.) Now, Wadsworth and Acopia senior consulting engineer Harald Skardal say their team has written software for the switch that creates proxy snapshots of a federated file volume based on underlying EMC and NetApp arrays. The snapshotting is based on the same proxying techniques by which the switch creates a global namespace for NFS and CIFS files.

Acopia deployed APIs from EMC and NetApp to create the snapshot function. Results of the test, which was conducted in Acopia's lab using two shares on a NetApp FAS3050 filer and two shares on an EMC NS 700 filer (with both CIFS and NFS clients) are available on request, the vendor says.
