Silver Peak

Speed is becoming critical for IT managers as they look to share applications between data centers and branch offices. This, in turn, has prompted a flurry of activity from WAN optimization vendors, although the cost of the technology remains a stumbling block for some users.

Next week, for example, Silver Peak Systems will take the wraps off its high-end NX 8500 device, which it claims will offer users almost three times the performance of its previous high-end box, the NX 7500. (See Top 10 Startups to Watch, Silver Peak Enters WAN Arena, and Silver Peak Starts Up.)

Other suppliers are getting in on this act. Next week Juniper will unveil its own high-end WAN optimization box, the WXC 590, which, according to the vendor, can support up to 45 Mbit/s of throughput. This figure, however, is based on internal testing and customer feedback.

Juniper's previous offering, the WXC 500, could handle 20 Mbit/s. The vendor is also expected to make announcements about new routing and application front end technologies next week.

Riverbed, for its part, recently gave its Steelhead devices a speed boost, and last week the company announced that Liz Claiborne has deployed the technology at 37 sites across North America, Asia, and Europe. (See Riverbed Intros Solutions, Claiborne Deploys Riverbed, and Riverbed Details IPO .)
