Data General has announced that it will launch a NUMA server with 64 Intel processors by the end of the year. The high-end server, code-named Audubon 2, will be based on what DG is calling the third generation of its NUMALiiNE Non-Uniform Memory Access (NUMA) technology. NUMA is a shared-memory multiprocessing architecture similar to Symmetric Multiprocessing (SMP), but it allows higher numbers of CPUs in one system. The Audubon 2 server will use Intel's forthcoming Slot 2 version of the Deschutes processor, a member of the Pentium II family. The Slot 2 Deschutes, expected in the second half of 1998, will allow four-CPU multiprocessing, and is the successor to the Pentium Pro for the server-market. Current servers in Data General's Aviion line range up to a 32-processor 200MHz Pentium Pro machine - four of which can be clustered together. DG hopes the new servers will offer four times the performance of its current top-of-the-line 32-processor server. This server was recently benchmarked at 3305.8 QppD and 1277.7 QthD on the 300Gb TPC-D benchmark, which measures data warehouse performance. The gain in performance is to be made thanks to a doubling of the number of processors and the higher clock speed of Deschutes (no exact data is available, but cheaper Slot 1 Deschutes processors are expected to reach clock speeds of 350MHz to 400MHz by midyear). The Audubon 2 will support up to 64Gb of memory and up to 400 terabytes of storage. The system will be built up out of quad-processor units, each based on Intel-designed quad-processor motherboards. Up to four of the systems will be able to be clustered together, for a total of 256 processors in a cluster. The server will run DG's own DG/UX operating system, which is based on Unix System V Release 4. The company said that it already has a NT version of its NUMA technology working in its labs, but has not yet announced product plans for NT-based NUMA servers.
