We performed a comparison between Dell SC Series, Hitachi Universal Storage VM [EOL], and VMAX [EOL] based on real PeerSpot user reviews.
Find out what your peers are saying about Hitachi Vantara, IBM, Dell Technologies and others in Frame-Based Disk Arrays."Everything is sub-5 MS for us. What I've found is that, with all-flash, when an app from my business is slow, I pretty much know it's them and not me. It leads to a performance conversation that has really hit an interesting threshold point where we are better than what they need. So now we get to have that "refactoring your application" conversation a lot quicker because now the performance on the infrastructure side isn't in question anymore."
"The most valuable features are the with back-end dedupe, and the thin nodes. For a 20TB or 60TB, we're using almost a one-to-two ratio."
"We replicate between SAN to SAN for a lot of features and supportability. It also helps us when we want to upgrade to a newer SC Series or move the data from one data center to another."
"I think that Dell EMC is one of the best technical support services in Ukraine."
"One of the most valuable features is the capability to switch between all-flash to hybrid, which have have actually done for one of our arrays. We started with the hybrid, with the limited if I'm not mistaken, and then over a period of time, we swapped all the hybrids with the SSDs. This was one of the big features because it gave us the capability to not stick with just one kind of media. Secondly, since it has sorted clustering, we were able to bring in the newer boxes and have it all clustered together. These were the two main features that we really looked into, which benefited our use case from an expansion/growth perspective. Another valuable feature is the ease of management."
"In terms of stability, it's good enough. It's okay."
"It had many features, like a snapshot, replication, on-the-file RAID levels, mix-and-match files, those kinds of things."
"They have a feature called Live Migrate; it's been very, very useful."
"The most valuable features are simplified provisioning and management, de-duplication, and built-in encryption."
"We have never had a bad experience with it because we never had failures. It has good data availability and the performance is also okay."
"The most valuable features are the interface and performance."
"The interface is good, and it is also customizable."
"It works with our replication technology, which is not SRDF, which is native replication technology."
"VMAX3 is our main system for storage. All our systems and all our virtualizations are connected to it. In terms of expanding it, we are replacing it with a new system, the PowerMax 2000. So our current VMAX3 platform will be decommissioned soon. We are switching to PowerMax 2000 because we are looking for improved performance. We see it as the best fit for our requirements in terms of the performance and the overall cost."
"This solution is resilient."
"A rock solid foundation to deploy applications which cannot incur a disruption of service."
"We have been able to present storage from the VMAX to hosts without any problems."
"The lower model, the 3000, should have duplication. It doesn't right now. It's only from 5000 that this is offered, but it depends on the performance. It could be they don't offer it on lower models because the duplication is too much of a burden to the performance."
"An issue we had was that the controller went down during an upgrade because of their upgrading the code. One side of the switch was down."
"The connection should be better integrated with the network to offer a better view of the system."
"The SC Series doesn't support NVMe storage."
"Overall, I'd like to see more synergy between Dell EMC's higher-tier platforms and their mid-tier platforms. What I have said, constantly, to my partners at Dell EMC is that the clear articulation of the path is really important to us. In that vein, what I'd also like to see is, with the migration strategy that's built into this product, a lot more attention paid to Dell's - in particular - legacy platforms and how we get from some of our legacy EMC platforms onto this platform with a straight-through migration and scaling strategy, not host-based migrations and not piecemeal... Dell EMC would do well to focus more on my ability to skip a generation, rather than having me take individual hops because I can't greenfield my way into a software-defined data center fast enough. This journey of multiple hops is not helpful."
"I would like to see an integrated key manager in the controllers. Currently, it's an external product. It would be nice to have the option of having a built-in key for self-encrypting drive features."
"The lack of reporting would be the main issue."
"We have seen some degraded throughput with mixed workloads. We have been working with Dell EMC to correct some of these latency issues."
"The exterior display needs to be improved."
"I would like to see support for high-availability."
"I would like this solution to integrate the solution that EMC vPlex offers."
"The cluster support should be improved."
"The way you configure larger size volumes needs improvement."
"Resilience replication, reporting, and performance need to be improved."
"The pricing is a bit expensive. That is the reason we are now currently we are looking for other solutions. That's the reason we are looking at AFF and Unity. We are also considering PowerStore."
"Better speed to release new features that have become industry standards. EMC created so many standards in the past. Now, it seems they are playing a me-too game and lagging behind in some areas, specifically data reduction."
"I'd like to see improvements where we can scale out an existing array and remove older controllers\drives\etc., within the same subsystem."
