"The Nasuni filer is software that provides a CIFS and NFS gateway interface to files stored in the cloud and looks like a regular network-attached storage (NAS) filer to applications and servers. It comes as a VMware virtual machine and needs a 500GB disk cache, which it uses to deduplicate data going to the cloud and rehydrate it on the way back, if the original data is no longer in cache."

"Nasuni is working with a selected group of cloud service suppliers including Amazon S3, Iron Mountain and Nirvanix. Customers carry on doing e-mail and database applications as currently, but send files off to the cloud in the world according to Nasuni. They'll need a high-speed Internet connection to make this work properly."
