In terms of Dell PowerScale (Isilon) specifically, we have seen a return on investment due to faster performance than our last few storage arrays, and the general usability is a lot better.

Previously, we had latency issues with syncing up files between offices. Files were not locked, leading to overwrites which cost us literally hundreds of thousands of dollars in lost time and revenue.

The pricing is excellent.
Director, Information & Communication Technology & Digital Transformation at a educational organization with 201-500 employees
It did require us to purchase new hardware, however, that was not overly expensive.
Senior Vice President, Technology at Halff Associates, Inc.
They should consider more attractive pricing for companies of our size.

There is no degradation of speed because these filers have cached the data, and they are constantly swapping metadata and updating with each other, which is a very attractive method of getting us to use these applications.

Systems Engineer at Unisity LLC
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.
Roger Clark - PeerSpot reviewer
I.T. Infrastructure Manager at Thompson Engineering
Handles file locks effectively enabling seamless remote collaboration in global teams
It has not reduced the data storage cost. We have been trying to come up with a plan internally to archive project data at a certain time frame. However, our data continues to grow, so at the point of 25 terabytes, we had to buy another 25 terabytes license to exceed that threshold. It would have been nice if they had offered them in increments, of 5, 10, 15, or 20 terabytes than having to get a whole chunk of 25 terabytes again for licensing purposes, which is a little costly. It would be nice if Panzura offered data in increments instead of 25 terabytes per license. They have done a pretty good job of development from the point of offering new products. Pricing seems to be high for certain things, such as the audit feature of Panzura Data Services. It would be nice to see who deleted that 100 gig of data out there. They should make the pricing plan more attractive for a company of our size. We have almost 700 employees over the southeast from Texas to Florida and up to Tennessee, so we are a pretty big region.
