Novell Inc, Provo, Utah has announced a three-phase strategy for implementing multiprocessing technology in NetWare 4, having enrolled Tricord Systems Inc, Compaq Computer Corp and NetFrame Systems Inc as multiprocessing hardware partners. Dubbed Distributed Parallel Processing, the technology is said to combine symmetrical, asymmetrical and clustering technologies. Phase 1 will see Novell incorporating a symmetric multiprocessing kernel in NetWare 4, which it says will enable resource-intensive portions of NetWare (including local network and disk driver support, encryption, media manager, and communication buffer management) to be load-balanced across multiple processors. According to Novell, the architecture will continue to support existing single-processor NetWare Loadable Modules, but a set of symmetric multiprocessing application programming interfaces will also be published, to enable developers to write symmetric multiprocessing-based NetWare Loadable Modules. Phase 1 developers kits are to be launched some time this year. The company says, however, that users will not be able to assign existing single-processor NetWare Loadable Modules to different processors during Phase 1. The second phase of the company’s strategy builds on the domain architecture that was introduced in version 4 of NetWare, by enabling NetWare Loadable Modules running in separate domains to be load-balanced to additional server processors.
Not revealing a timescale
Phase 3 is intended to build on this by providing full distributed parallel processing by addressing CPU-intensive applications on NetWare servers with industry-standard shared-memory hardware. Also to be added is a distributed Lock Manager, designed to enable the operating system to take advantage of asymmetrical multiprocessing hardware, which is being provided by NetFrame as its contribution to the hardware partnership, and derived from technology built by Oracle Corp. In the form of NetWare Loadable Module software, Novell says that it enables multiple processors to work together in either symmetric or parallel environments on a single application. Finally, clustering will also be incorporated, enabling multiple servers to pool storage resources and processor utilisation for example, offloading tasks from overloaded servers to idle servers. Novell is not revealing a timescale for phases two and three of the strategy. Novell says that Compaq is providing engineering expertise and testing resources for the development of Distributed Parallel Processing as part of the hardware partnership, which is also designed to ensure compatibility with Compaq servers. The relationship between the two stems from their Enterprise Computing Partnership announced last September. For its part, Tricord is to provide on-site engineering expertise and PowerFrame enterprise servers. Finally, Novell says it is also working with Intel Corp to provide support for its PC+MP specification, which it says has already been implemented as part of its phase 1 Distributed Parallel Processing technology.
