Reasonably priced, scales well, and offers good stability
We primarily use the solution for cluster applications and databases. We use the solution on the DBA and those that use double machines Being able to have broken files on-site on the same appliance is quite useful. The newer version of NVME has a really noticeable difference in quality versus the…

Supports both protocols, highly stable, and straightforward setup
Dell Unity XT is used for almost all types of mid-range requirements, such as databases, virtualization, file services, and other applications, for example, exchange servers Dell Unity XT has unified storage which provides both blocks, and file protocols, which helps to get rid of separate…

Effective provisioning, helpful support, and reliable
When we set up the solution we did not require a lot of support from the teams. The good thing about the support is they can access and upgrade the framework and all other aspects. However, the account managers from Pure Storage are not communicating very well with us. We want to talk to them about what features should be used, use cases, best practices, and other technical discussions. Additionally, we would like to know about the new features, the introduction of new technology in the storage itself. It would be nice if they could communicate this information to us. The support is very good. They always call us for technical upgrades and firmware. If we have any issues they log in and we open a session for them, and they help us. The only issue is the time zone difference between our time zone and their time zone. I would rate the support from Pure Storage FlashArray a five out of five.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:


"The most valuable feature of this solution is its ease of use."
"The solution is scalable."
"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."
"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."
"The high availability of the product is the most valuable feature."
"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"What I really like about this program, is that it is easy to use and easy to configurate."
"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."
"We can put all the virtualized servers in one place, so our customers can share and manage the devices very easily."
"Initial setup is a simple process."
"VMware integration: Grants both the Storage and Virtual Administrator the ability to create and mount datastores, or even to check how much space each VM is consuming."
"The initial setup was very straightforward. Migration was smooth and configuration of the storage was quick and simple. The time needed to put it into production was less than expected, and data migration itself went without a glitch."
"Its main advantage over vSAN was the rebuild, the intelligence of the restoration in the event of a hardware drive failure and, of course, the all-flash solution."
"I have found Dell EMC Unity XT to be stable."
"The high availability of Dell EMC Unity XT has been the most important feature."
"The All-Flash models are pretty fast for the vast majority of our remote workloads."
"It has been very stable. I have not seen or heard of downtime storage issues after moving over to it."
"The connections are a lot faster than what we had in the past. One InfiniBand does what we did on all of our Fibre Channels."
"The solution helps to simplify storage."
"Access speed and power consumption are most valuable."
"I find two features of Pure Storage most valuable. The first is the "safe mode" function, and the second is its simplicity."
"Pure is simple to set up and manage on a day-to-day basis."
"I use all the features of this solution and I find them to be easy to use and functional, such as the compression and capacity to expand."
"We find the ease of usability and setup valuable."


"The tool's portfolio is minimal. It is expensive."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"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."
"In terms of what needs improvement, the dashboard and management could be simplified."
"The tool's pricing is higher than competitors."
"There is room for improvement in the pricing of the product."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"The user interface could be improved. The Dell Compellent user interface is fantastic, but the Unity user interface is, in comparison, pretty lousy. It's functional, and I can do what I need, but the Dell Compellent user interface is so much more intuitive and user-friendly."
"I would like to have secure mobile connectivity going forward. This would help me be more proactive."
"They should have more wizards for customers so they can do more of the self-service types of functions, in terms of upgrades and patching, although it's pretty easy right now."
"As the solution continues to grow and gain more traction, things will come up that will just continue to deepen the integration between VMware, vCenter, and all those other components. Anything in the divisibility there and additional tools is always great."
"It would be nice to have been able to easily move off our old VNX system to this system. The process is very manual."
"Thick provisioning of LUNs."
"Dell Unity XT could add a unit-to-unit replication. We haven't seen that because we don't have an additional one to test. However, it is not an improvement, but something that we would like to have visibility on how it's done or how it works."
"It could go faster. Make it bigger, better, and faster at a lower price, and I am there."
"The scalability of the solution is not as good as it probably could be."
"If they could make it cheaper, that would be something."
"We need to add more storage in Pure Storage FlashArray with the cluster mode activated for us to have better performance."
"Currently, the solution fails to support file screening."
"As long as they always improve on IOPS speed, that's all we're really looking for. The faster the storage can be the more we can do speed of application and speed of use."
"There are many features which need to be added, particularly on the replication side."
"The price should be lower."
"The higher education moves slowly. We are still looking forward to implementing the full list of existing features."

Pricing and Cost Advice

"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"The tool is an investment that we've budgeted for. While the prices may be higher than those of other vendors, we see it as a market leader with benefits. We don't regret purchasing it."
"With VMware, we pay $300,000 annually."
"The product is expensive."
"Its price could be better. It is not too expensive, but it is the high-end cost. It is kind of a Rolls-Royce. You pay a lot, but you get a lot out of it. So, the price pressure on the way down would be great, but at the end of the day, if you need to do the work, you just pay for it."
"With Pure Storage, we would like to continue seeing price reductions with flash storage. I don't think we're any different than anybody else when we continue to look to the industry for price reductions of both NVMe and traditional SSD storage. We would like to see these prices continue to decline and erode, even displacing large spinning disks."
"Pretty much everything that you need is licensed when you buy the product. Licensing to me is different than the maintenance cost, but they can bleed into one another. We buy the product, and we expect three years of support bundled into what we negotiate on our storage arrays. I would start to see maintenance costs going into the fourth year, but we're not there yet."
"We pay approximately $50,000 USD per year in licensing fees."
"At the end of the day, the licensing cost is key, because every customer has a pain point, that the cost of each piece is high. So if they would bundle everything in a package, that is how the competitors are selling their footprint."
"Licensing is easy since all the software is included."
"The price in our country is very expensive and some of our customers opt for lower-cost alternatives."
"The return on the investment was simply speeding up our entire vSphere stack, which allowed our developers and engineers to get their workloads done faster and simpler. We were experiencing VM snapshot times of 45 minutes to two or three hours, and it shrunk it down to under five minutes."
"The pricing is competitive. We miss some of the feature functionality that we had with the XtremeIOs but it's certainly suitable for the purpose."
"It is a good return on investment."
"Compared to other EMC platforms, Unity is nice because it is all-inclusive, in terms of the licensing model. That's unique for them, compared to other manufacturers. It is beneficial. We could use replication, native, right out-of-the-box."
"We integrated it with VMware vSphere at no additional cost. As we moved into VMware vSphere, this is what we bought to go with it for our storage performance."
"I would rate the pricing of Pure Storage FlashArray a five out of ten. It is expensive but not too much."
"It is light years beyond anything else with the same price point."
"The best features come included without any additional cost."
"We have an Evergreen Storage subscription, which I think is a great feature."
"It's a good price point and it's a solid product for the price."
"It is cheaper than NetApp."
"It could always be lower, but it's okay."
"The price of the solution is not expensive."
