A New End to End Solution The petro-gas giant wanted to have a disaster recovery solution with a secured & robust system for transmitting digital information.

Progressive's solution consists of setting up a Disaster Recovery Site, which recovers all the existing operation from the Primary Datacenter – maintaining business continuity.

The operation consists of financial transactions, user's mailbox with Exchange 2007 with more than 4000 users. The Exchange Mailbox Database with CCR will be replicated in the Disaster Recovery Site using the Exchange 2007 Standby Cluster Replication (SCR). With the help of this Exchange Mailbox will be replicated to DR site in real time from Standby node, which will take care of any site disaster issue. The PSU chose to go with this solution as it was convinced of Progressive's technical expertise. As far as progressive was concerned, it was a very prestigious project as it involved one of India’s biggest PSUs.
