We performed a comparison between Dell PowerScale (Isilon) and IBM FlashSystem based on real PeerSpot user reviews.
Find out in this report how the two NAS solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."This has been a valuable solution for our business overall. It offers business continuity and replication features."
"Dell PowerScale is a scalable solution. It allows non-disruptive upgrades and maintenance of the system."
"The solution is extremely easy to manage. This is its most valuable feature."
"Dell PowerScale's performance is good."
"Its scalability has been huge for us."
"I don't have to rebuild the cluster to add a node."
"Isilon is flexible in supporting various data workloads while keeping them protected. Dell continues to release updates and patches which enhance the use of this solution. This includes offering ransomware protection."
"Our main goal is to do disaster recovery with whatever solution we use and Isilon makes it pretty simple to replicate those workloads over to our secondary data center."
"It is simple to make an update."
"The most valuable feature of the solution is replication...Stability-wise, I rate the solution a nine out of ten."
"It's a mature product. It's like a BMW that evolves consistently."
"The FlashSystem 900 consistently delivers performance below 1ms for read/write. This performance is essential for an effective SVC stretch-cluster configuration across two datacenters, and presenting active-active storage to the customer."
"FlashSystem offers proven technology in a compact package."
"The speed, performance, and stability are the best features of IBM FlashSystem."
"The power systems are very reliable if you are running 24/7 operations. For ongoing mission-critical applications, it's the best solution."
"This solution is very stable."
"The product’s expansion capacity, pricing clarity, and ease of use need improvement."
"The solution’s interface and pricing could be improved."
"Dell PowerScale (Isilon) could improve the load distribution capability. For example, in some cases, the system load is not distributed automatically on all the nodes but is concentrated only on one. You have a peak request on only one node and the others don't do anything."
"The solution can be a bit complex for those not well versed in the technology."
"The solution's rate structure or rate redundancy needs to be improved."
"We used to have a chat feature available on the support site. It's not available to us anymore."
"If they integrated some functions, as they have on Data Domain with a cyber recovery vault, it would be ideal."
"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."
"The design is a little old-fashioned and could be updated. The rack is very primitive and designed in an older style."
"AHV is Acropolis Hypervisor – A relatively new Hypervisor, robust and stable as VMware vSphere, has built-in advanced analytics and powerful operations, Self Service Portal and components for DevOps included, managed by a single pane of glass (Prism) via HTML5 and it is free of charge – That is why Nutanix is so advanced and revolutionary."
"One area for improvement is in the GUI, where host clusters are not properly dealt with. With Hypervisor host clusters, all hosts must see the same volumes in the same order. Using the concept of a “host-group” has been around (even with IBM) for many years, so why not with the V7000?"
"Events/log analysis tools."
"Our model does not support compression or deduplication."
"With regards to the IBM V7000 storage system, where we have multiple tiers of storage, a heat map would show I/O distribution across the tiers of storage."
"The deduplication and compression ratio is not very good. It's not reaching a very high ratio."
"The solution is not easy to implement. It takes a lot of time to study the product and it's a little complicated in general."
