We performed a comparison between Dell Unity XT and VMware vSAN 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 most valuable features of this solution are its ease of use and performance."
"Pure has signature security technology, which cannot be deleted, even if you are an administrator."
"The solution is very straightforward to set up."
"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"Technical support has been helpful and responsive."
"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."
"Overall stability is very good. It is a very stable solution."
"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"Replication of the communication object (COB) scenarios"
"The product has helpful local technical support."
"After migration to Unity 300F, we were able to put more DBs on flash, reducing latency. The results were visible in the front-end systems, and all users noticed the improvement."
"The most valuable feature is the fast cache with functionality rewrite."
"The most valuable feature of Dell Unity XT is data duplication. Additionally, the management interface is simple, and is not a hassle using it. You don't need too much to learn or to be familiarized with it."
"It’s helped with the overall stability of our VMware environment."
"The solution overall has high performance."
"When I have an issue and need technical support, I reach out to them either through chat or by submitting a service request, and the response is good."
"The most important thing is the simplicity of the product. It is a well-established product with good stability."
"The most valuable features of VMware vSAN are that it receives updates frequently, has good compression, optimized storage, and they provide webinars on what is new. Additionally, the integration with third-party products is good and it is easy to manage."
"All the features are working great."
"Being able to deploy multiple applications with virtual servers is the most valuable for us. The capacity of the system is quite constant so it's got some of the good features."
"The ability to have an HA cluster in the absence of a shared storage device or SAN."
"The most valuable feature is that it is software-defined storage. Also, being able to do maintenance on the fly is a real benefit: migrating off, updating, and then moving the guest back on to the nodes."
"The most valuable feature is the simplicity of its scalability: being able to grow it without having to make sure you get the right disks and the right nodes. The solution is also easy to manage. It's all right there in the vSphere Client. You're not going through multiple things. You don't have to know, once you've created the vSAN node. You add storage, it sees it, and you create your data storage from there. Everything is right there for you."
"The most valuable features are Erasure Coding, Deduplication and Compression, and the advancement in stretching regarding replication."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"In the future, I would like to see integration with enterprise backup systems."
"We need better data deduplication."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"In terms of what needs improvement, the dashboard and management could be simplified."
"There is room for improvement in the pricing of the product."
"We'd like to see a cheaper version of an all-flash array in that footprint."
"Include cloud-based replication for blocks"
"It's not as reliable as it should be, I think it was probably released a little early. We've had production problems with customers, and there are still some challenges at scale as well. Compression is a problem for the system. Once you enable dedupe and compression, the performance of the system, the capability, halves... It has to be right-sized and sized for compression, but even with that, because there are only two storage processors, you're ending up at almost 40 percent usage."
"This product has some scalability issues. Before you can get support, you have to look for the service tag number on your product which could make it difficult to access support."
"Improve the administrative user interface so it is easier to work with. Currently, a simple task, such as removing a host from 100 LUNS, takes a lot of time. If they could improve LUN to host model to be more like the EMC VPLEX, for example, it would be great."
"I would like it to be a little bit easier to contact support. We can contact support, but we have to go through a phone tree. We get routed to different places. I might call support to say that I need a drive replaced and get transferred to three different groups before I get to the group I actually need."
"A customer had to buy VMX because Unity didn't have WORM."
"The solution should include a free process in the HPE portal that uses serial numbers to verify that hardware is genuine."
"The UI could certainly be better. The inside into what's actually going on with vSAN would be nice to know."
"The ability to access SAN environments with fiber channels (or even NVMe) would be a good addition."
"The solution could be improved by having more filtered and multiple view volumes instead of a single view."
"I lose a node in a cluster vSAN, which is also used as a cluster HA. I lose not only the storage part, which is not necessarily serious (depending on the configuration of the vSAN cluster), but on the other hand, I lose also a node of Compute, which can make things complicated quickly."
"The only negative point relates to the licensing. If you want multiple, different servers, it costs money, but you have all the capacity for vSAN. You do not reach the data, but the processor arrays and the current architecture."
"We would like to see even more storage capacity."
"The main problem we had was hardware compatibility, finding the right hardware that was certified."
"As no product is 100% perfect, the price for VMware vSAN could still be improved, though it is good when compared to some of its competitors."
