We performed a comparison between Dell SC Series and Dell Unity XT based on real PeerSpot user reviews.
Find out in this report how the two All-Flash Storage solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"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."
"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."
"We're able to get higher-density workloads on the same infrastructure, and we have a smaller physical footprint. The performance is excellent – during our test the bottlenecks are never on the X array, it just keeps picking up the pace to match what you need. The real-time visibility is a differentiator in my opinion."
"The most valuable features of Pure FlashArray X NVMe are its superior performance compared to other flash tiers, as well as its ease of use, with an intuitive user interface that is simple to deploy and use."
"Pure has signature security technology, which cannot be deleted, even if you are an administrator."
"One of the best features is the support, which is excellent."
"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."
"Performance-wise it's high speed. It's also more stable and scalable."
"The process of reallocating data from fast disks (SSD or SAS) to slow disks (SATA) gives you better performance and better use of resources."
"The solution has a wide variety of valuable features. The data progression works well. We use the snapshot functionality quite a bit and really like it."
"Its leading feature is the price-performance ratio, which is very good."
"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."
"The solution is stable."
"They have a feature called Live Migrate; it's been very, very useful."
"I like that the solution is scalable. The initial setup is not complex. The basic licenses and software are included in the package. he primary advantage is that this product has been thoroughly tested and proven over time. I recommend this product."
"I have found Dell EMC Unity XT to be stable."
"Unity's are more easily administrated, so we need fewer people to do the administration. We have less overhead because of that."
"Real Unified Storage (Block, File, VVols) in a unique 2U hardware."
"In the hybrid version, I would say they are fast. They have fully automated storage tiering. In the all-flash version, higher performance, compression, data replication."
"It’s helped with the overall stability of our VMware environment."
"Setup is simple."
"User friendly interface"
"It is on the expensive side."
"They could add more support for file storage and different types of storage."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"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."
"This solution could be improved if overall performance was improved and operated with a higher speed and supported a higher volume of RAM."
"The administration and support (on the way that they delivered) was a little bit slow."
"While the price is competitive, in the next release it would be better if they could reduce the fees."
"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."
"While there's always room for improvement in everything, I can't really think of a specific feature of the solution that requires immediate attention."
"In terms of additional features, I would like to see some kind of I/O meter, to indicate what we are using in terms of performance. I would like to see automation with that, where it would give me the trends. I want to know those things easily, to help me know where issues are going to occur."
"The connection should be better integrated with the network to offer a better view of the system."
"This is a tier-three solution and it gives us what we need for archiving and backups."
"We went to the PowerMax because of the needs that we have for the business. We're doing true enterprise-level storage. So we went from Unity to PowerMax to give us that tier that we were looking for."
"It needs deduplication. We'd like to have the dedupe capabilities in the Unity."
"I think there are a couple of things on the file side that we're lacking from the VNX world. It would be nice if we got some of those back. I think there are limitations on how many file systems you can back up at a time. Whereas you can do, I believe, eight continuous per data mover on the file side on the VNX, you can only do something like two or four on Unity. If they could step up to that, that would be good."
"There is an ESRS problem that we're facing where, for some reason, the other Unity has not been able to register to EMC. The support information is not upgrading and nobody can tell me what is wrong with it. It's a minor issue, the ESRS is still working, but it is something that is very confusing and nobody seems to know what to do about it."
"There is no de-duplication. Unity used to be Bionics, which had de-duplication; however, in Dell Unity XT, the de-duplication was deprecated and is no longer available."
"The only issue is with the product's scalability because it's not as scalable as the other polished tools in the market."
"The price of Dell Unity XT could improve."
