Ejasent Announces Utility Computing Industry's First Persistent Connection Migration Product.Business Editors/High-Tech Writers MOUNTAIN VIEW, Calif.--(BUSINESS WIRE)--Oct. 22, 2003 Ejasent Inc., the leading provider of utility computing (1) Pay-per-usage processing provided by a service organization that uses its own computers and facilities. Customers access the computers via a private network or over the Internet and are charged according to how much computing time they use, such as CPU seconds, minutes or hours. solutions for today's data centers, announced today the availability of the UpScale Connection Filter which enables connection and session preservation during dynamic application migration from one server to another. In today's era of Internet computing computing - computer , the network drives applications, and thus the availability of applications and their connections is a critical issue for CIOs today. With UpScale's Application Virtualization A smaller umbrella term within the larger umbrella term of "virtualization." It refers to several techniques that make running applications more protected, more flexible or easier to manage. See virtualization, network virtualization and storage virtualization. and connection migration capabilities, IT managers now have the ability to instantly scale resources for complex, multi-tiered applications, without losing any application or connection availability or data. "Application service availability is the final frontier in data center availability. Key to achieving this is the ability to preserve and move connections between machines. This is especially important for databases and ERP (Enterprise Resource Planning) An integrated information system that serves all departments within an enterprise. Evolving out of the manufacturing industry, ERP implies the use of packaged software rather than proprietary software written by or for one customer. applications where connections are persistent and a loss of connections will result in incomplete transactions," says Rajeev Bharadhwaj, Ejasent's CTO (Chief Technical Officer) The executive responsible for the technical direction of an organization.

Ejasent's patent-pending application virtualization technology provides an abstraction layer Software that translates a high-level request into the low-level commands required to perform the operation. The most common abstraction layer is the programming interface (API) between an application and the operating system. between applications and the underlying infrastructure, enabling dynamic mobility of applications across servers. This allows applications to be scheduled to available servers from storage or migrated between servers during server maintenance or when additional capacity is needed. Connection Filter from Ejasent significantly enhances Ejasent's industry leading application migration capabilities, enabling not only on-demand processing power, but now also, seamless support for migrating and scaling up connection-based applications in real-time. The result is the ability to schedule applications as and when needed, across available computing resources with Ejasent's policy-based control and execution software. When a database or an application with frequent or persistent connections reaches the limits of the underlying hardware, the application must be given additional resources to continue to operate at desired performance levels. Typically, this is accomplished by shutting down the application or database and restarting it on a different machine, which will cause the application to lose its state and connections. With the Connection Filter, this can be accomplished by moving the application, together with its process and connection state, to a larger machine, without any loss of state or connections. Ejasent benchmarks show the migration of a running Oracle database with 200+ connections from a 1-processor to a 4-processor server in less than 10 seconds, preserving process state and connections, with the migration completely transparent to the end users. Utilized across a data center environment with many large enterprise applications, UpScale provides a data center automation capability, which dramatically increases both utilization and maintainability of application environments. Ejasent's patent-pending Connection Filter is a module within the UpScale policy-based application management and virtualization An umbrella term for enhancing a computer's ability to do work. Following are the ways virtualization is used. Hardware Virtualization Partitioning the computer's memory into separate and isolated "virtual machines" simulates multiple machines within one physical computer. system. Ejasent's UpScale dramatically improves the performance and utilization of IT assets by dynamic scheduling and allocation of resources allocation of resources Apportionment of productive assets among different uses. The issue of resource allocation arises as societies seek to balance limited resources (capital, labour, land) against the various and often unlimited wants of their members. to enable centralized application management and on-demand computing See utility computing. . UpScale utilizes Ejasent's patent-pending snapshot/restore technology, which virtualizes applications across pools of server and infrastructure resources and then dynamically provisions and de-provisions complex, large applications across different servers based on demand.
