Semiconductor maker Voyan Technology Corp. says it can demonstrate components that deliver 10Mbps to 50Mbps on copper pairs over distances of 9,000 to 12,000 feet. This is a significant improvement over DSL technology that performs slightly better than T-1 speeds over those distances. DSL can deliver higher bandwidth, but only over short stretches. The Voyan technology has not yet been put in commercial products.

Following an industry-wide trend toward storage abstraction, Unisys Corp. last month announced a new storage appliance that pools disk storage from various vendor products on a storage area network and serves it up to clients or backs it up as if from a single source. Unisys’s Storage Sentinel is a RAID controller device that comes in a refrigerator-size cabinet with 2TB of internal storage. It features snapshot, striping and mirroring capabilities over multiple platforms and applications. Blue Bell, Pa.-based Unisys said its focus is on selling services, with the company’s appliance being 75 per cent of the cost of rolling out a standard US$200,000 Storage Sentinel configuration. Unisys Storage Sentinel, which will be available Sept. 4, complies with the Storage Networking Industry Association’s Common Information Model, a consistent way of mapping management elements in a network.

Cylink Corp. and Expand Networks Inc. are teaming up to deliver a way to compress traffic across VPN links, making it possible to keep down the cost of these connections.

They will push the combination as a way to reduce the volume of traffic to storage area networks as well as a way to keep down the costs of business-continuity measures. Cylink and Expand have not yet announced details of their joint sales and marketing plans.
