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."Most of the problems that we had in the past with the performance in IOPS have disappeared. It has been a great improvement for our customers' services."
"The performance and the ever-growing maintenance are the most valuable features of this solution."
"The deduplication and compression meet all of our system requirements."
"It is easy to manage. You don't have to have the same people who used to manage the Dell EMC arrays because the solution is more intuitive."
"The deduplication in the array combined with its snap technologies allows the product to be remotely/manually controlled or scheduled."
"We've had to use tech support on a number of occasions. They did everything remotely and talked us all the way through. They fixed the issue within 30 minutes. Every single time we contact them, they're perfect. I would give their technical support a ten out of ten."
"It's actually very stable"
"The most valuable feature is that maintenance is free."
"They have a feature called Live Migrate; it's been very, very useful."
"The solution is stable."
"The solution is stable; we've had no problems at all."
"I find this version to be more budget-friendly compared to products from other vendors. This aspect greatly benefits my customers. It's highly advantageous due to its affordability. The operational aspect is also noteworthy. Additionally, its availability and performance are commendable. The speaker are also equally powerful."
"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."
"Connecting it up, you can run it within a few hours."
"The flexibility of this solution has been valuable for our business."
"The user interface is good, I would rate it a nine out of ten."
"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 haven't seen ROI."
"A year ago they promised that they would be able to read through the database encryption with more metric and they have not delivered on that patch, which is significant because it gives us back so much more storage room. We want to be able to read through the encryption."
"Currently, the solution fails to support file screening."
"The only time that we had problems with it was that there was a bug in the VVol implementation but, outside of that, it has been flawless."
"With scalability, I have run into a little problem with our last upgrade. There were some undocumented limitations to the number of drives that our controller could run on. So, instead of putting in a new data pack as we had anticipated, we had to keep adding and removing to get up to the capacity that we needed to be. What should have been a one day process (or a few hours) turned into a month and a half process."
"The initial setup was a little complex. We had some initial issues with the design and had to help correct some of the white papers for it, but it wasn't your standard use case."
"Pure Storage FlashArray could improve the recent file storage capabilities because it is lacking a lot of features."
"The solution could improve by having a multi-tenant feature."
"I don't think the solution is very scalable."
"The cost of the solution could be better."
"One option I would like to see is, when you're up on the view-screen, to be able to incorporate getting to what HPE call the iLO, the Integrated Lights-Out. To be able to get that instead of having to go back and trying to find IP addresses and re-institute those would be good. It would be good to be able to that put on the initial splash screen."
"Compellent comes in the form of a component that's not true of a unified storage platform."
"The ease of use could be improved. It took me a while to learn it."
"The initial setup is somewhat complex and should be made simpler to do."
"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 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."
