NetEx, F5 Face Up to DR Reality

WAN optimization vendors F5 and NetEx are cranking up their disaster recovery strategies.

NetEx yesterday unveiled an upgrade for its WAN optimization solution, which it claims can push data replication speeds through the roof in the event of an emergency. This followed EMC's recent announcement that it would resell F5's WANJet Appliance in conjunction with its SRDF replication software.

StorageTek spinoff NetEx positions itself as an alternative to traditional WAN optimization products from the likes of Riverbed, Silver Peak, and F5, touting its HyperIP offering as a software-based way to boost backups.

HyperIP uses a proprietary transport protocol that runs over UDP (User Datagram Protocol), which NetEx says compensates for the latencies involved in typical TCP/IP transmissions. As a result, the appliances, which run on off-the-shelf Intel-based hardware, can alleviate TCP/IP degradation associated with long-distance data transfer, according to the vendor.

Yesterday NetEx added a feature called Recovery on Demand to HyperIP, comprising a software key that gives existing users access to up to 622 Mbit/s of bandwidth for up to 10 days free of charge, according to Bob MacIntyre, vice president of business development at NetEx.
