"We found that to be extremely valuable, especially where the environment can't afford that extra hardware," said Melerud.
Kemp is unique among commodity server load balancing vendors in its support
of terminal services, according to Steve Steinke, research director for
networks at The 451 Group in
However, the lion's share of the terminal services belongs to Citrix with its Presentation Server, which incorporates its own load sharing technology, Steinke said. The upgrade is available Feb. 11.
