Although Digital Equipment Corp is portraying that all is still sweetness and light between itself and Microsoft Corp, that has not prevented DEC from seeking to steal a march by yesterday announcing Digital Clusters for Windows NT Server, which connects two Alpha or Pentium computers running NT in a fault-tolerant configuration. The Clusters software, due next month, cost $1,000 per computer, and while it presently works only with DEC Alpha or Prioris machines, it says that when Microsoft finally comes out with its Wolfpack answer to NT clustering, DEC will resell Wolfpack with added features from Digital Clusters, and support other computers. Wolfpack was to have used the clustering technology Microsoft licensed from DEC (CI No 2,725) but after a lot of prevarication, Microsoft now says openly that it has eliminated all DEC technology from Wolfpack.
