State Bank of India : Datacenter Consolidation

The foreign offices of SBI were operating out of three datacenters (DC) and

three Disaster Recovery Centers (DRC) in India, USA and UK. The bank faced the

high cost of operations, problems in version control of hardware, OS and

database, and had difficulties to roll out new functionality across various

datacenters. In order to resolve these issues, the bank decided to consolidate

all DCs and DRCs to single locations in India. The project had to meet the

objectives of consolidations of DC/DR sites in USA and UK into an Indian DC and

DR site. It was decided to undertake the consolidation on new generation of

hardware, operating systems and databases to take advantage of new technologies.

The entire migration had to be done on live production databases/apps with very

short downtime window on account of business considerations.

By consolidating the datacenters at one place where the domestic network is also

placed, the bank has seen reduction in OpEx to the tune of US$ 1.06 million per

annum, while the overseas manpower has seen cost reduction of US$ 0.37 million

per annum. This new setup has shortened the window for end of day batch

processes and backups, leading to the increase of the availability of the

application to the business users by more than 25%.
