Innovative ClearPath Libra 450 Server Delivers Power and Flexibility

There’s a new ClearPath in town — the Intel® Xeon® processor based ClearPath Libra 450 Server. This platform is just the latest in what’s now a long line of Next-Generation Server Architecture systems that deliver everything you expect from a ClearPath mainframe at a lower total cost of ownership. What’s more, you sacrifice nothing in the way of MCP operating environment security, reliability, and capabilities while gaining the flexibility to run Microsoft® Windows® 2008 Enterprise Edition x64 on the same server hardware.
The Libra 450 Specs
The entry-level Libra 450 open mainframe offers up to two quad-core Intel® processors, along with a lower price entry point and maintenance costs that are aligned with other Intel® technology-based systems.
The Libra 450 Server boasts a performance range of 40 – 300 MIPs (972 to 7,290 RPMs) — with single thread performance of 200 MIPs — making it ideal for a wide variety of demanding workloads.
As always, there’s no need to recompile or make any changes to your applications to move them to this MCPvm based platform. Complete code compatibility remains a hallmark of the ClearPath family of servers.
Finally, the Libra 450 platform offers Unisys powerful Capacity on Demand option, which allows organizations to respond to unpredictable changes in demand by quickly tapping into additional horse power via temporary performance, emergency, and/or disaster recovery keys.
Match Business Needs to IT Costs
The Libra 450 system offers four flexible software-licensing options:
- User-based pricing on the two entry-level models (in increments of eight)
- Traditional MCP licensing based on performance models
- Agile Business Suite workload licensing
- Software Developer’s Kit workload licensing with all compilers and application software development tools included
These options are designed to help you easily align your infrastructure expenditures to business demands.
