We performed a comparison between Dell PowerScale (Isilon) and VAST Data based on real PeerSpot user reviews.
Find out in this report how the two File and Object Storage solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."It has allowed us to have more consistent quality controls. It has also allowed us to expand the number of servers in clients processing and accessing data, allowing us to get a lot bigger projects out the door."
"The guaranteed performance, combined with the scalability through its scale-out capability, makes it an excellent choice."
"The solution has simplified management by consolidating our workloads. Rather than managing all the different workloads on different storage arrays, Windows Servers, etc., we just have one place per data centre where we manage all their unstructured data, saving us time."
"The most valuable feature of the solution is its performance."
"The solution's scalability is very good."
"PowerScale has made it extremely easy to scale file data across our organization. We have two implementations of Isilon. One is a replica of the other. When scaling, we add nodes to each location and expand the cluster. The process is straightforward."
"The most valuable feature we started using, beyond the initial scope for the solution, is the multi-protocol system that allows you to access the same set of files using different network protocols like NFS or SMB. PowerScale’s Unified Permission Model ensures that data security and access permissions are honoured regardless of whether the client is a Windows desktop or a Linux server"
"The single pane of glass for both IT and for the end-user is a valuable feature. On the IT side, I can actually control where things are stored, whether something is stored on solid-state drives or spinning drives... The single pane of glass makes it very easy to use and very easy to understand. We started at 100 terabytes and we moved to 250 and it still feels like the exact same system and we're able to move data as needed."
"The solution is useful for machine learning and scientific applications, including computer simulations."
"This has been one of the most reliable storage systems that I have ever used."
"The product needs to improve CLI since commands are complex. The search option is also difficult since you must give the full path."
"Some improvements to the NFS support would be of interest to us."
"That said, for the other security features, it would be helpful if Tenable - and I know it's outside the scope of this question itself - had Isilon-specific plugins."
"The management and monitoring tools comprise a disparate suite of products and the roadmap is very unclear. We've got four different products that look after the Isilon, management-wise, and it's a bit of a mess."
"The only thing that I think PowerScale could do better is improving the HTTP data access protocol. At the present, you cannot protect access to data via HTTP or HTTPS the same way that you can secure data access through other protocols like NFS or SMB[...]the Unified Permission Model that would allow a user to authenticate before being able to access a private file, does not apply."
"Dell PowerScale (Isilon) is a bit expensive compared to other products."
"Additional metadata reporting would be great. We have to use a separate tool to report on that. We would like to view the age of data and how long it has been since someone has accessed a file."
"If they integrated some functions, as they have on Data Domain with a cyber recovery vault, it would be ideal."
"The write performance could be improved because it is less than half of the read performance."
"The read/write ratio is an area in the solution with some flaws and needs improvement."
