Hardware vendor Compaq is to offer multi-server clusters by the end of next year, according to an internal document that outlines the company's clustering strategy.
Following a tie-up with Tandem, Compaq will incorporate the company?s Servernet router-based technology into its clustering architecture, which currently supports only two servers. This will enable future clusters to support more than two machines and external shared storage.
In the first half of 1997, Compaq expects to deliver a two-server configuration running Windows NT in parallel. As well as offering failover functions, like the vendor's current clusters, the new versions will offer souped-up performance through the use of Servernet components. They will also link to external storage through a fibre channel interconnect.
Later in the year this will be followed by a multi-server failover solution that will employ Microsoft?s Wolfpack clustering technology. Microsoft is positioning Wolfpack, due to be introduced some time in 1997, as an enabling technology and an open standard for NT clustering. It will include support for a cluster-wide name services, cluster management programming interfaces and Wolfpack-aware applications.
By the end of 1997 Compaq aims to have introduced multi-server clusters that implement full parallel processing. With these clusters, multiple servers with Servernet boards will be connected to a series of Servernet routers, which will then interface to external storage devices using the fibre channel. All servers will be aware of each other?s presence and will share storage. Support for Oracle Parallel Server and other databases will also be included, along with performance administration tools.
