A leading US based life insurance company.

The IT infrastructure of the client consists of over 100 servers – Sun / IBM / Intel along with a number of smaller servers spread across 3 different data centers in USA. These host a variety of web and database applications running on two different environments viz Solaris and AIX and are configured as Web, Application and Database servers. With a need to reduce the total cost of operations and embrace standardization, the client wanted to consolidate the servers and move towards a Linux environment.

In this consulting assignment, the interdependencies of the servers/applications, their usage pattern and performance factors were first studied. Wipro proposed that the Web Servers presently running on SPARC / Solaris be replatformed and consolidated on Intel / Linux and recommended BladeCenter after evaluating various servers. For the Application and Database servers, the LPAR technology from IBM was suggested. For Linux adoption, Wipro proposed a phased approach involving Web servers followed by Application and Database servers.

	Number of servers reduced by 50% by adopting the LPAR technology leading to ease of administration
	Increase in speed of performance, since the Blade servers are more powerful than the original servers and provide greater capacity & performance within the same footprint
	Protection of investment by the fact that pSeries systems with LPAR supports both AIX (the existing operating system) and Linux
