We performed a comparison between Dell Unity XT and Pure FlashArray X NVMe 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."The solution is easy to scale. I'm running two environments right now, so I need to scale. I'm running a part technology. I've got an A-side and a B-side."
"The tool is simple and easy to use. It has neat features like protection from device removal. Moreover, you can undo the deletes. The solution is easy to work with and not as complicated as CAC"
"My rating of Pure Storage is a ten out of ten because of the price for performance and footprint - the overall value."
"We consume less physical storage because of the solution’s deduplication and compression."
"The amount of throughput that we're getting is really nice."
"As soon as we introduced our first Pure Storage FlashArray, the first benefit was at least twice the performance increase. Our production databases simply ran twice as fast with no other change."
"The most valuable feature is that maintenance is free."
"Very stable; no worries about how much it can handle."
"It is easy to manage overall. It is all web-based. It has a an easy, nice dashboard. I receive emails if there are issues. When there are any updates, I receive emails. I can either do them on my own, but normally I schedule them with Dell EMC and they remote in, then it's done."
"The feature that I have found most valuable is the unified storage. Also, its capabilities for block-access, file access, and the center box."
"The Unity XT box is very strong. It doesn't break. The MTBF time is very large so you don't have to worry about faults or outages in your operations."
"Scheduled components are sourced from Korea based on their quality selection, with the actual purchase taking place in Vietnam. The notable features include cache memories and MOS feeder in Dell Unity. Additionally, the storage dynamics are managed uniformly on a global scale, whether it is a simple or wide-ranging configuration."
"The most valuable feature is that the solution is a hybrid system, so you can do both block and file storage."
"It is completely reliable. The plugins for it are quite mature. I don't really have any issues with the interactions with vSphere, they all work as intended."
"The most valuable aspects of this solution are its stability, performance, and ease of updating."
"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."
"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"Pure has signature security technology, which cannot be deleted, even if you are an administrator."
"The high availability of the product is the most valuable feature."
"It has good, reliable, fast storage."
"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."
"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."
"What I really like about this program, is that it is easy to use and easy to configurate."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"They could improve the price."
"I would like some form of QoS implemented. As a service provider, it would be beneficial to have it."
"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."
"It took us a year to get it to stabilize and to get the best out of Pure."
"We do have an issue with the vCenter integration. Pure Storage says it has a lot of free space, but vCenter says its completely full. This is because their dedupes are saved as space, but Vcenter still detects the disk as completely full. So, we do have an issue with that."
"If we suddenly dump large amounts of data onto the storage system, it takes a while to process it."
"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."
"The one major gripe I have is that there is no snapshotting enabled by default on the SAN."
"We've got an ongoing issue with a Unity where some power supply fans spin up. We've had a whole bunch of hardware changed as a result but I still have an open SR which has been a struggle. It doesn't seem to affect performance, but it's something that we're hoping the engineers can resolve. Also, we had some issues with an upgrade where we can't manage a device, after the upgrade. So we had to have a ticket in for that."
"In terms of what could be improved, I would say its capacity and its connection."
"Perhaps if they added more 10GB ports to the back of the system, so you have more IOPS out of the box itself to the network, that would help."
"Maybe deduplication would be something that would be better to have. Also, it's a fairly new management interface, so work is still being done on that. But compared to other vendors and previous EMC storage, the Unity is really good."
"We have had some downtime. Nothing is perfect. Unity’s have had some code-release problems, versions that, from a compatibility perspective, had some glitches which caused an outage. But, given the amount of Unity’s we run, that has been fairly minor and it hasn't happened at scale or across all of our Unity’s."
"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."
"The initial setup is not so straightforward if you don't have experience with storage arrays."
"Replication with VMware - it's called the vSphere Metro Storage Cluster - is lacking in the Unity and is present in Compellent."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"There is room for improvement in the pricing of the product."
"The tool's portfolio is minimal. It is expensive."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
