Access "Caches with the Write Stuff"

Published: 16 Oct 2012

Do you think that collaborative file creation, editing, storage and management between geographically distributed users is a pipe dream? A new generation of startups doesn't think so. By combining traditional caching with techniques such as compression and two-way differential transfer, vendors DiskSites and Tacit Networks claim they can give remote users both read and write access to data over the WAN, at LAN-like speeds. DiskSites' product, the W-NAS, consists of the DiskSites FilePort and the FileCache appliance. Posing as a CIFS/NFS file server, FilePort resides in the main office, and connects to the FileCache appliance in the remote office, managing caching and data transfer. To cut down on the amount of data that travels over the wire, W-NAS transmits only those bytes that have actually changed. The result: Assuming a 128Kb/s connection with 100ms latency, and a 90% cache hit rate, DiskSites estimates that it can save a 600KB Word file in nine seconds--and 245 seconds without it. Tacit Networks claims similar performance improvements using their Tacit... Access >>>
