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."It is an SSD array that has awesome performance, low submillisecond latency, and does what it is supposed to do. It just works, which is difficult for things to do anymore."
"Pure Storage is extremely reliable — it's never failed."
"It helps to simplify storage because it has an easy front-end to access everything."
"With Pure Storage, we don't see any latency or IOPS. It has been a very seamless integration."
"They are quite responsive and our local team was pretty good."
"FlashArray has many valuable features. It's very user-friendly and it has high availability, so there is comparatively less downtime. During maintenance, there is no shutdown procedure, so you can directly power off the Array and manage the shutdown process without any data loss, which is a unique feature. Managing replication and data migration is also very easy."
"Their REST API is wonderful, well-documented, and easy to use."
"The product cheaper compared to other solutions concerning the technology that they are using."
"Easy management of volumes: You can create volumes and easily assign them to VMware clusters, increasing their size."
"It has been one of the most stable products in our data center."
"The user interface is good, I would rate it a nine out of ten."
"The interface is easy to use which makes the product user-friendly."
"The Dell support is helpful and the response is quick. The agents' knowledge is very good."
"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."
"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."
"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."
"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."
"The 3PAR SSD arrays that we have are still failing a lot so even though we're under warranty, we still have to get someone out and usually have someone troubleshoot so that usually adds onto the cost. With Pure, we've had a disc fail and we pop it out and you pop it in and it's good to go."
"I would like to see active replication. I know that it's available now but I haven't tried it yet. I hope that it works."
"In the next version of this program, I would like to see increased security, higher encryption, and faster throughput."
"I would like to see more detailed reporting on the data. However, it would be nice to know what are the exact VMs usage after deduplication and/or what that VMs actual latency and bandwidth is, outside of VMware."
"It is way in excess of what we need. If anything, we could see a bit more speed. I'm just comparing it with what some of my colleagues who are implementing their own systems do."
"In the next release of the solution I would like to see Vormetric native block encryption."
"One thing I'd like to see in a future release is integration between their main storage array and what they call their FlashBlade product; to be able to snapshot directly from the primary array into multiple different backup copies on FlashBlade."
"I would like to see data tiering to AWS."
"While the scalability is good, there are certain limitations."
"The SC Series doesn't support NVMe storage."
"Technical support should respond more quickly because the turnaround time is very high."
"The price could be improved."
"From a performance point of view, it's getting a bit old."
"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 ease of use could be improved. It took me a while to learn it."
"While the price is competitive, in the next release it would be better if they could reduce the fees."
"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."
