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 high availability of the product is the most valuable feature."
"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."
"Pure has signature security technology, which cannot be deleted, even if you are an administrator."
"FlashArray has some fresh efficiency features. I've never seen a storage solution with a compression rating this high before. It's at least 4-to-1 on Oracle databases. It's the best flash storage for Oracle."
"The Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."
"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"The latency is good."
"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"This solution is easy to work with and easy to maintain."
"VMware integration makes the life of our engineers easier, as we are almost 100% virtualized and this feature is used on a daily basis."
"The Unisphere management interface: We are very familiar with it. It manages all the EMC devices that we have. Management is easy because it is part of Unisphere, which is self-learning."
"The most valuable feature of Dell Unity XT is its support of protocols for both block, and file levels. It has the features a store solution should have."
"To be programmatically administered is huge, it is one of the key features that we like about it."
"With all-flash it should be able to scale. You probably just need one 4U device and you have terabytes of space."
"We use the solution for site recovery manager, DR, and endpoint penetration."
"The UI itself is fantastic, and the ease of administration is far better than Unisphere or Navisphere ever were. It's very easy to manage. The fact that it has built-in APIs means our automation people can help us automate a lot of tasks, and that has been helpful. And, of course, it's really fast. Obviously, that doesn't hurt anything at all."
"The ease of use is great."
"By eliminating dependency on that back-end storage, we now depend on everything that's in the VMkernel with vSAN. We eliminate the middleman."
"It's very scalable. I like that. Adding a node is easy. Adding a disk group is easy."
"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."
"The installation is very easy."
"VMware comes with different stacks like VMware Cloud Foundation, which is integrated with different VMware modules. There's interoperability between VMware products."
"The ability to have an HA cluster in the absence of a shared storage device or SAN."
"The solution's technical support is good."
"There is room for improvement in the pricing of the product."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"The tool's pricing is higher than competitors."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"We need better data deduplication."
"It is on the expensive side."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"They could add more support for file storage and different types of storage."
"I would like to see a more seamless virtual box integration with the physical box which can replicate, because the setup of the replication is very difficult right now."
"The monitoring part could be better. With EMC storage systems - or Unity and VPLEX, because I'm using them, for the moment - the monitoring part is very difficult. They should improve this to have a better reporting system."
"The support team is well-versed in the AMG solution, having received comprehensive training. They also boast strong partnerships in both VNAM and Korea. The system's user-friendliness is a primary consideration in their choice of solution, emphasizing the importance of service. They place a strong emphasis on service, occasionally requiring approvals. However, with full installations, they have achieved almost uniformity. Their storage approach differs from a consolidated business-based model; instead, it is application-centric. Their investment in solutions is geared towards specific needs, such as the banking or information system, acquiring smaller storage units individually."
"The price of Dell Unity XT could improve."
"The only issue is with the product's scalability because it's not as scalable as the other polished tools in the market."
"It could go faster. Make it bigger, better, and faster at a lower price, and I am there."
"This product needs to have better integration with enterprise backup solutions and archiving devices."
"It could be a little easier to attach it to a network file system."
"The product's complex setup phase is an area of concern where improvements are required."
"VMware vSAN could improve by having faster reload time and a single point of failure. Resynchronization of many hardware could be better. If you have an outage of a disc or a full system, the replication time is too slow. This has room for improvement."
"The product can be improved in a couple of ways. One of those would be that they have a lot of hidden features, that are through the CLI, that would be great to have in the GUI, or just be more open about those features. It's something called RVC. It's a tool in the back end. It's a really great tool, but I had to find it through Reddit. So more information on stuff like that would be great. Also, in the user interface, giving us more features and more reporting that we can do from vSphere itself would be helpful."
"VMware vSAN could improve by adding NAS and object storage."
"The solution could be improved by having more filtered and multiple view volumes instead of a single view."
"Disaster recovery needs to be improved, when there is a crisis, there is a problem with what is the quickest way to get out of it."
"One of the things that we've had challenges with are when we place hosts into maintenance mode. Sometimes doing so triggers large re-sync processes which can be time-consuming and which have, at times, pushed the capacity to the threshold. I definitely think making some changes in that area would provide some big improvements."
"The server files are larger than before."
