Lotus releases Domino for S/390 mainframes

Lotus and its parent company, IBM, yesterday rolled out a version of the latest Domino upgrade for the S/390 mainframe platform.

At IBM's Solutions 99 conference here, Lotus touted the delivery of Domino Release 5 for S/390 and cited benchmarks showing that platform to be the highest performing among those supporting the collaboration software.

According to Lotus and IBM officials, a single G5 server configuration of Domino R5 for S/390 handled 32,000 concurrent e-mail users and more than 42,500 transactions per minute, as measured by the NotesBench Consortium's third-party performance tests.

Officials predict significant improvements with the latest G6-generation S/390 servers.

S/390 assumes the top performance mantle from IBM's AS/400 server.

While the Domino upgrade is expected to appeal mostly to existing S/390 customers, the combination of R5 and S/390 will also figure in some new large-scale server consolidation projects, according to Lotus marketing manager Don Harbison.

The Domino upgrade roughly triples the number of users supported by Domino R4 on a single instance of the program, and permits the segregation of e-mail and application users within a single partition, according to the company.

The upgrade also brings Domino more securely into the S/390 fold, according to Product Manager Tom Burns who explained that R5's System Management Facility (SMF) support permits Domino to be managed via that S/390 facility. R5 for S/390 also supports IEEE floating point operations and digital certificates.

Lotus also changed the pricing of Domino for the S/390 to a MIPS and usage basis, factoring in both a server's processing capacity and actual usage.

IBM this week also announced plans to ship the enterprise version of its WebSphere application server on S/390 by the end of the year.
