Flexibility and reliability have supported seamless data growth
I cannot think of anything to improve about Dell PowerScale (Isilon). The hardest challenge we have is due to how we've bought things over time. The way that we moved to the PowerEdge platform for the newer systems creates a scale problem as I still buy the older style systems, which are more dense storage. They're different chassis, so the problem we run into in the data center is the depth of the actual equipment. The newer equipment, if we buy an FX910 or a 900, it's a lot shorter in scale than if I buy an 83,000, which is much bigger. This makes it more complicated for deployment.

Reliable and secure storage solution supports core banking operations effectively
The replication technology that Hitachi Virtual Storage Platform uses is quite older, and the replication methodology they employ for data between the data center and the production and standby database shows no significant improvement in that particular field. With respect to storage administration, I'd like to see more clarity on the encryption side; data being stored in an encrypted manner is essential, but the customer or end-user doesn't understand which encryption is being used and doesn't have a direct view stating that their data is encrypted using AES 256 or DES, or whatever standard they follow. This lack of transparency may not be acceptable during audits.
