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.
