Policy scheduling gives multiple applications on a single Unix server

Transaction processing (TP) applications such as a cash transaction, for example, typically receive a high policy and thus more resource than batch processing applications such as bank statement runs which would receive a low policy and, therefore, less systems resource. According to ICLthe technology is expected to cut the cost of enterprise computing by as much as 35%.

On those occasions when Unix systems have been asked to run more than one application, allocating systems resources has meant rigidly allocating processor time to each application. The new approach is to set a series of pre-defined policies which the system then manages itself. Each application has resource allocated to it according to that policy. As the balance of applications changes from Transaction Processing to batch, for example, the system manages its resources to optimise the speed with which each application is handled. ICL is shipping the Policy Scheduler as part of a services package for the Trimetra range.

The Trimetra XtraServer is the first enterprise Unix/NT system designed for running multiple applications. The XtraServer P1000i is an Intel-based, UnixWare and NT server with up to 10 Pentium-Pro processors with 16-32 way systems. It also offers the new SCO UnixWare SVR5. The DY server is to be shipped next year. The XtraServer Pi to follow. The Teamserver Mi range with up to 6 Pentium Pro processors is available through ICL from Fujitsu-ICL The SY, LY, Mi and Pi models are shipping now.

Components for the new Pi come from a variety of company's including Fujitsu, Unisys and Data General, as well as Intel, SCO and Microsoft. Larger systems, to be released next year, will involve similar technology partnerships. ICL is collaborating with Intel's Merced 64-bit technology programme. The results of this collaboration will also be fed into the product range. Pi systems will be available in the UK this year, and subsequently in other territories.
