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."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."
"Lone segmentation is simpler and more agile. It's improved the velocity in overall provisioning from project to operation."
"The performance and the ever-growing maintenance are the most valuable features of this solution."
"The technical support is very good."
"The solution offers amazing performance."
"Having an intuitive user interface to get things running is great."
"It has good stability for our company."
"Their support system has insight into errors on our SAN fabric that we can't see. They've brought attention to and raised awareness for us about things that we couldn't see, when we were experiencing problems."
"It has helped us be able to use less administrators per device or system. Therefore,we are more streamlined."
"We just started doing a bunch of automation where, if an end-user's home directory or departmental share gets filled, I can set certain things through a Unity API so that if it reaches 95 or 98 percent full, it will automatically expand. Now, instead of our getting a ticket and having to go in and do it manually, it does that for us."
"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."
"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."
"Its quick integration with VMware. The ability to stand up a data store in one place, where you don't have to go and rescan for the data store through the vCenter Client, as well as SMB shares. This ended up being a big selling point for us."
"We put the Unity on one of the file servers and the backup performance improved quite a lot."
"The Snapshot feature is key."
"The most valuable features of Dell Unity XT are the data compression for all of our VMs up to four times and the performance is good."
"The high availability of the product is the most valuable feature."
"The most valuable feature of this solution is its ease of use."
"Pure has signature security technology, which cannot be deleted, even if you are an administrator."
"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"The initial setup was extremely simple and straightforward."
"The most valuable features of this solution are its ease of use and performance."
"One, it's easy to use and understand. You don't have to be an engineer or an expert to use this storage solution. That's the bad part of Dell PowerMAX. You have to go through very expensive education for one or two weeks and pay ten thousand dollars just to be able to use the product. With Pure Storage, you have a half-day workshop, and you know everything you need to know."
"Overall stability is very good. It is a very stable solution."
"The time-to-market could be better at times, but I think that's true for all vendors of hardware."
"We would like to see better troubleshooting aspects. It helps us if we can find out where the problem is. Right now, it's difficult. Sometimes it's difficult to pinpoint the issue. If they had more visibility and more troubleshooting feature built into the tool that would really help."
"We need to add more storage in Pure Storage FlashArray with the cluster mode activated for us to have better performance."
"This product has only two active controllers, whereas other solutions can have more. This is something that needs to improve."
"With scalability, I have run into a little problem with our last upgrade. There were some undocumented limitations to the number of drives that our controller could run on. So, instead of putting in a new data pack as we had anticipated, we had to keep adding and removing to get up to the capacity that we needed to be. What should have been a one day process (or a few hours) turned into a month and a half process."
"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."
"The number of Filesystems is limited, which it is not on the EMC VNX."
"Its price needs improvement. Its price is almost double than any other flash storage solution."
"We noticed in the last release of code that there were some inefficiencies around getting our data efficiency up in terms of dedupe and compression."
"We are running VMware, and with the VNXe it was possible to restore. We're using Veeam for VMware backups and with the predecessor, it was possible to mount a backup or restore a backup from a storage snapshot. With the Unity 300, this is not possible."
"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."
"My only complaint would be some of the CLI Help files could be a little more detailed, but that's very minor complaint. We were trying to run some commands just to see how the storage snaps were interacting with the storage array, and it was a little difficult to look up exactly what commands should be run. The Help files detailing what exactly the commands did wasn't as detailed as we would have wanted them to be."
"Our request to Dell EMC for improvement was in the reporting and monitoring areas. Dell EMC built up a cloud ID so that we could see the overall storage numbers. We needed to have the proper KPIs to be able to see and manage things."
"The VNX reporting is much more granular, versus the Unity reporting."
"Issues with slow responses from the support team."
"We had one incident with a memory leak that led to controller reboot. Although it had no impact, when such things happens the storage should be more aware of it, send alerts, and propose corrective actions."
"We need better data deduplication."
"You cannot tag a LUN with a description, and that should be improved. What I like on the Unity side is that when I expand LUNs or do things, there is an information field on the LUN. This is the Information field that you can tag on your LUNs to let yourself know, "Hey, I've added this much space on this date". Pure lacks that ability. So, you don't have a mechanism that's friendly for tracking your data expansions on the LUN and for adding any additional information. That's a downside for me."
"There is room for improvement in the pricing of the product."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"I'd like to see the product implement active replication for vehicles such as VMware."
"I would like to see replication and DR features in the next release of this solution."
