EJASENT ANNOUNCES PERSISTENT
CONNECTION MIGRATION PRODUCT
Ejasent Inc, the leading provider of utility computing solutions for
today's
data centers, announced 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, 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 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 applications where connections are persistent and a loss of connections
will result in incomplete transactions," says Rajeev Bharadhwaj, Ejasent's
CTO.
Ejasent provides utility computing software for policy-based, centralized
management of applications and the allocation of underlying processing
infrastructure in response to demand. Ejasent's patent-pending application
virtualization technology provides an abstraction layer 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-plus 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 system. Ejasent's
UpScale dramatically improves the performance and utilization of IT assets by
dynamic scheduling and allocation of resources to enable centralized
application management and on-demand 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.
