The integrated specialty engines are optional. They will ship with all Libra 4100 systems, and if customers decide they want to use them they can buy a license key to enable them. The JProcessor engines are $20,000 each and the ePortal engines are $25,000 each.
Unisys has been developing sPar for several years. It first conceived it for use with its standard Intel-based servers as a rival to VMware. But it decided that competing with VMware wouldn't be "beneficial" and developed the technology for its mainframes instead, Maclean said.
The Libra 4100 and Dorado 4100 systems announced Tuesday are both four-socket systems based on six-core Xeon chips, and both offer a significant performance boost over their predecessors, according to Unisys. The single-image system capacity for the Libra 4100, for example, jumps from 800 MIPS to 1750 MIPs compared to the Libra 4000, while single-processor performance is up from 200 MIPS to 300 MIPS. The entry price for the Libra 4100 is around $550,000. Pricing for the Dorado 4100 wasn't immediately available.
