Tamilnad Mercantile Bank, LTD. Ensures Data Protection With Riverbed's Steelhead Appliances.

100 MB File Replicated Between Chennai and Bangalore Every Two Minutes

SAN FRANCISCO -- Riverbed Technology, Inc. (Nasdaq:RVBD), the performance leader in wide area data services, announced today that the Tamilnad Mercantile Bank, LTD. (TMB) has selected and deployed Riverbed's Steelhead[R] wide-area data services (WDS) appliances to ensure that its critical banking transaction data is not lost should a disaster occur. TMB has deployed the Steelhead appliances in the company's Chennai data center and in its Bangalore disaster recovery center.

TMB is a premier private sector bank headquartered in Thoothukudi, with seven regional offices and 173 branches across India. TMB was founded in 1921 and is one of the few private sector banks in India that has successfully evolved in the rapidly changing Indian banking industry. TMB has continuously recorded profits for the past 84 years.

During peak business hours, TMB generates a 100 MB log file every five minutes. To protect this critical banking transaction data, TMB replicates the files from its Chennai data center to its Bangalore disaster recovery center. Prior to installing Riverbed's Steelhead appliances, replication of this file using Oracle's Data Guard application took more than 10 minutes. If a disaster were to hit during peak business hours, TMB risked losing over 200 MB of data. TMB recognized this risk and sought a solution. The company considered upgrading bandwidth as a solution; however, this option was very expensive and, TMB learned, would not improve the replication time. The company turned to WDS vendors for a solution and selected Riverbed's Steelhead appliances over the competition. In in-depth evaluations, Riverbed clearly delivered the best performance.

Following installation of the Steelhead appliances, time to replicate TMB's banking transaction data dropped from over 10 minutes to two minutes. Data traversing the wide area network (WAN) has been reduced by over 65% and WAN utilization is down to less than 50%. Prior to installation of the Steelhead appliances, utilization was more than 90%.

"It is critical that we protect our banking transaction data," said P.R.Varatharajan, general manager, Tamilnad Mercantile Bank. "We have designed our disaster recovery (DR) systems to ensure that we do not lose any data should disaster strike. Riverbed's Steelhead appliances have become a critical component of our DR architecture."
