The ClearPath HMP IX6800 server from Unisys Corp. has 20 percent better price and performance than previous ClearPath IX servers, according to Unisys officials.

The top-of-the-line ClearPath has a single-chip IX CPU that works 60 percent faster than ClearPath IX CPUs, said Thomas Freeman, director of ClearPath business operations and strategies.

The single-chip IX processor executes between 150 million and 160 million weighted integer and floating-point instructions per second with more onboard cache and overlapped instruction execution than before, he said.

The IRS and Defense Information Systems Agency megacenters are big users of ClearPath servers. In 1998, DISA bought 24 of the ClearPath HMP IX5600 and HMNP IX5800 servers, Freeman said.

Two sides

ClearPath HMP IX servers have dual personalities, which lets them run Microsoft Windows NT, Santa Cruz Operation UnixWare or Unix alongside Unisys' OS2200 operating system.

Some Unisys sites still have programs operating under OS2200 that were written 30 years ago for now-defunct Sperry computers, Freeman said.

The ClearPath servers compete in the high-end transaction server market with against IBM Corp. System/390 and Hitachi Data Systems Corp. Skyline servers, Freeman said.

The ClearPath HMP IX6800, which accepts up to eight IX processors in a chassis, executes up to 4 billion instructions per second in clustered configurations.

How much

The dual-personality server costs $3,000 to $5,000 per MIPS, including the OS2200 operating system.

Unisys in September will release a new high-end Aquanta server, the ES5085 with eight 500-MHz Pentium III Xeon processors running Microsoft Windows NT 4.0 and Unisys' Enterprise Software Suite.

Priced from $35,000, the Aquanta has extra hardware for load balancing and partitioning, said Mark Feverston, vice president of Aquanta marketing and sales operations.

'No matter what their applications, users will get performance improvements of 40 percent to 90 percent' compared with performance levels from current four-way Aquanta servers, Feverston said.

Unisys plans to pretune and prepackage the Aquanta models as dedicated servers for consolidation, thin-client networks, or enterprise applications from PeopleSoft Inc. of Pleasanton, Calif., and SAP America Inc. of Wayne, Pa.
