Data General announced that it will ship by the end of the year a NUMA server with 64 Intel processors. The new 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 4-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 200 MHz Pentium Pro machine - four of which can be clustered together. Data General 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 300 GB 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 350 to 400 MHz by midyear).
The Audubon 2 will support up to 64 GB of memory and up to 400 terabyte 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 Data General's own DG/UX operating system, which is based on Unix System V Release 4. "We will keep enhancing DG/UX as long as Intel keeps making 32-bit processors", said DG spokesman Carlos Soares.
For future 64-bit Intel processors, Data General is working with SCO to add NUMA technology to the forthcoming 64-bit version of UnixWare. However, Data General is apparently wavering in its support of UnixWare. "When the time comes to move to 64 bit, we will see what products are out there in the market place, and we will pick the best product", Carlos Soares said.
Data General also sells servers running Windows NT. Carlos Soares said the company already has a NT version of its NUMA technology working in its labs, but the company has not yet announced product plans for NT-based NUMA servers.
