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."The best feature is consistently lower latency, even when IOPS crank up to over 75K. The product maintains submillisecond response time, which is incredible."
"We find the ease of usability and setup valuable."
"One of the features that my customers are really interested in is immutable snapshots. There are immutable snapshots to which your applications can be reverted back if you are hit by some kind of ransomware threat or malicious attack. That's kind of a key deal, and it is one of the selling points I use to point out to my customers the value and the features that Pure Storage brings to the table."
"Before we used Pure Storage it took 93 days of employees who run the database to back up and restore databases. The scale of deployment basically went from several days to a few minutes."
"The performance is very good."
"Data reduction and compression. Sub millisecond latency."
"All updates, upgrades, and hardware work are all performed on-line with no impact."
"This solution has improved our organization in the way that we used to see latency but now with this solution we don't. It also has good performance. Latencies have come down for our performance in the SQL databases. We can put a lot more in a lot less in terms of space savings. We also save data center space have good deduplication."
"The solution is stable."
"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."
"It is fast and performs well."
"The product offers good performance and is quite powerful."
"In terms of stability, it's good enough. It's okay."
"The setup and installation is much simpler now, because Dell has standardized the configure process."
"The most valuable feature is the speed for the end-user."
"Its leading feature is the price-performance ratio, which is very good."
"This has been one of the most reliable storage systems that I have ever used."
"The solution is useful for machine learning and scientific applications, including computer simulations."
"We did have one hiccup with the integration of vCenter. When we were installing Pure Storage, we were using vCenter 6.7, which defaults to the HTML5 Web Client. The current plugin for Pure Storage doesn't show up in that client at all. You have to go and use the legacy FlexFlash client to see the Pure Storage plugin in vCenter."
"I feel like there is too much automation; the user doesn't have any manual input."
"It was not proactive communication."
"I would like to have support available in Spanish."
"Historical analytics would be useful. At the moment, they don't have any type of application built for historical analytics."
"There are scenarios with very specific functionality around VMware integration particularly to do with the way we'd like to manage LUNs in VMware. The tools are pretty good but there's room for improvement there."
"There are many features which need to be added, particularly on the replication side."
"Larger capacity and more storage ports would be the two things I'd like to see."
"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."
"I would like to improve the processing ability."
"Compellent comes in the form of a component that's not true of a unified storage platform."
"The interface could be improved. It should have an application point of view."
"It's not very efficient anymore. There are better products out there."
"The lack of reporting would be the main issue."
"There's always room for improvement in the operating code."
"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."
"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."
