Unisys Enhances ClearPath Enterprise Servers to Help Clients Conquer Growing Information Overload


New high-end ClearPath Dorado and Libra models with enhanced operating environments enable clients to take on disruptive trends in the data center

BLUE BELL, Pa., – Unisys Corporation (NYSE: UIS) today announced the most powerful members ever in its family of ClearPath enterprise servers.

The new ClearPath Dorado and ClearPath Libra 800 Series feature innovations designed to handle clients’ growing mission-critical workloads. Those include more powerful Unisys-designed processors and I/O capabilities, as well as enhancements to the ClearPath software operating environments – such as support for Apple iPad tablets and Android and BlackBerry smartphones, enabling mobile users to access data center resources more easily.

Enterprise information-processing requirements are growing exponentially. According to a 2011 research report from the University of California, San Diego, in 2008 “the world’s servers processed 9.57 zettabytes of information . . . This was 12 gigabytes of information daily for the average worker, or about 3 terabytes of information per worker per year.”1

“Right now, disruptive trends such as growing numbers of smart devices and increased use of software-as-a-service and other cloud-based solutions are multiplying transaction loads and driving information-processing levels even higher,” said Bill Maclean, vice president, ClearPath portfolio management, Unisys. “As a result, enterprises urgently require more powerful servers. These latest ClearPath enhancements demonstrate Unisys’ commitment to give clients additional computing flexibility to deal with constantly emerging requirements while building on their long-term investments in strategic applications.”

High-Powered New Servers Meet the Highest Transaction Requirements

The new ClearPath Dorado and ClearPath Libra 800 Series servers are designed to handle rapid transaction, networking and storage growth across a range of industries, including transportation, government, telecommunications, financial services, insurance and utilities.

The ClearPath Dorado 800 Series, comprising six new models, enables clients to migrate applications transparently across multiple generations of the Dorado server line and reduce total cost of ownership.

The Dorado 800 Series improves processor performance up to 70 percent and I/O performance up to 740 percent over predecessor models Dorado 280 and 380.2

Unisys has also announced a new, third generation of the Extended Processing Complex Locking (XPC-L) enterprise clustering innovation available for the Dorado 800 Series and other Dorado systems. With enhanced capabilities for high availability in the most mission-critical applications, the XPC-L3 enables up to four host systems to access a shared database concurrently – even down to the same record. It synchronizes database access so records are always accurately updated, simplifying both day-to-day operations and disaster recovery.

The new two-model ClearPath Libra 800 Series provides hard partitioning so clients can configure a server as a single system or one with multiple independent environments. The new models feature processor performance up to 50 percent higher and I/O performance up to 59 percent higher than predecessor Libra models 585, 680 and 780.

Some models in each of the two new ClearPath series offer traditional performance-based pricing, while others use metering, a pay-for-use system software licensing capability that enables clients to pay only for the processing power they use.

New Software Enhances Application Modernization and Mobility Support

Unisys developed and tested the new releases of the ClearPath operating environment – OS 2200 Release 13.0 and MCP Release 13.1 for the Dorado and Libra lines, respectively – as integrated software stacks. In each case, 120 or more operating-system, database, transaction-management, communications and other products have been integrated to deliver high performance, availability and reliability.

This tight integration enables the new environment to be deployed on previous and future generations of ClearPath systems, relieving clients of the need to perform system integration themselves while enabling them to preserve and build on their prior investments in mission-critical infrastructure and applications.

By enhancing the operating environments, Unisys has also added capabilities to specialty engines integrated with the ClearPath systems. These special-purpose processors enable clients to meet evolving data center requirements, such as application modernization and creation of service-oriented architectures (SOA), open application development and enhanced security.

For example, the ClearPath ePortal for MCP and the ClearPath ePortal for OS 2200 now provide integrated support for a growing array of mobile devices, complementing the Apple iPhone support the engine already provided. The enhancement of the ClearPath ePortal engines gives clients new ways to create more modern interfaces for enterprise applications without changing the applications themselves. It also provides mobile workers access to application resources through a broader range of familiar looks-and-feels.

Similarly, Unisys has added automated failover to the ClearPath OS 2200 QProcessor, which provides transparent information exchange between systems through the widely used IBM WebSphere MQ Server messaging facility. This new software feature enhances system availability in heterogeneous mission-critical environments.

The ClearPath Dorado 800 Series and all software enhancements are available immediately. The ClearPath Libra 800 Series and the XPC-L3 are scheduled for availability in June and August 2011, respectively.
