We performed a comparison between Dell SC Series and VAST Data based on real PeerSpot user reviews.
Find out what your peers are saying about Dell Technologies, NetApp, Pure Storage and others in All-Flash Storage."Technical support has been helpful and responsive."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"The duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."
"It has benefited my organization because it has reduced time to insights."
"The solution is very straightforward to set up."
"The most valuable features of this solution are its ease of use and performance."
"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"The solution is stable."
"The most valuable feature is the speed for the end-user."
"In terms of stability, it's good enough. It's okay."
"Customers are most impressed with SC's provisioning because you don't need to buy a large amount of storage upfront. It's pay-as-you-grow. It also has solid compression and duplication features."
"The user interface is good, I would rate it a nine out of ten."
"The most valuable feature is the no-forklift upgrade. While the thing is running, I can change out the controllers one at a time and keep the customer up and running. I can add shelves and storage and SSD drives or spinning drives to the system, while it's running. I can bring all that in and rebalance the load across the new disks or, if we take disks away, rebalance the load across what's remaining, and it just works."
"A valuable feature is the performance of the auto-tiering. It will move hot data up to your fastest Tier 1 or move your slow data down. Data progression is what it's called. With the auto-tiering you can have multiple tiers, you can have your Tier 1 be either spinning or flash, all the way down to 7.2K. It will change the RAID on the fly so your writes come in at RAID 10. After they sit for a while, they get converted to RAID 5, then they'll cool off and move down the tiers. Your performance is kept going, while the cold data is moved to your slow, non-performance tiers."
"The Dell support is helpful and the response is quick. The agents' knowledge is very good."
"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."
"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"I would like to see replication and DR features in the next release of this solution."
"The UI for this solution needs to be improved."
"In terms of what needs improvement, the dashboard and management could be simplified."
"Right now, the box itself is just strictly working as a backend storage system. It would be fantastic if we could access it directly like a NAS device through network access or SIS drives. I think they have an interface, but I am not sure how good it is. If we could address a box directly on the network without having to go through a server, it would be great. The replication schemas could be improved. We are not using replication on the storage level right now. We use a different type of replication. If their replication would be as good as the one that we have, I would probably run the replication schema because it might be faster, but I don't know that for a fact. So, I cannot say that they have good replication. All I can say is that they need to inform us better."
"We need better data deduplication."
"Technical support should respond more quickly because the turnaround time is very high."
"We can definitely see a need for it being a multi-controller system for customers who want to scale beyond the current capability. That's always a downside. A lot of the new systems are scaling vertically, they scale out, and the Compellent, of course, is controllers with shelves under it, so you don't scale out with it, unless you add another one. But if you do, they don't talk to each other, like some of the other solutions that we sell."
"In some customer cases, customers experienced more performance or latency."
"The cost of the solution could be better."
"It would be helpful if the solution offered higher performance, at least on the back end."
"Snapshots in VMware. You can’t do snapshots since the storage itself does that. Therefore, some apps (Veeam, for example) don’t work well with this kind of tiering storage."
"The initial setup is somewhat complex and should be made simpler to do."
"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 read/write ratio is an area in the solution with some flaws and needs improvement."
"The write performance could be improved because it is less than half of the read performance."
