Supports efficient storage management through volume snapshots and offers reliable non-disruptive upgrades
I have no specific improvements to suggest for Pure FlashArray X NVMe at this time. The performance statistics could be enhanced. I can see the performance statistics in the Pure Storage console, but it does not show the performance by 4K byte unit. It displays IOPS and bandwidth, but IOPS is about real use, and I want to know how many IOPS are currently running in 4K byte units. I cannot see that IOPS because most storage systems report their performance by 4K byte unit. I want to see Pure Storage performance by 4K byte unit to compare with other storage or other internal NVMe SSD.

Customer needs are addressed effectively with collaborative sales and service support
Recently, customers have been asking for a cloud tiering option in storages. Some Dell storages do not have cloud tiering, which is an optional commercial feature. NetApp's FSA model 2750 comes with an inbuilt cloud tiering option. In the future, if Dell storages include this option, especially for Unity, it would help us target SME or medium enterprises for quicker closures and support the sales team.

A versatile storage solution suitable for various workloads in cloud environments providing scalable architecture, granular Quality of Service and consistent performance
The most significant benefit lies in its exceptional performance, driven by its Flash-based architecture. This enhances routing speed and, consequently, database performance. The provisioning process is efficient and doesn't demand higher latency, ensuring optimal data transfer performance which is particularly valuable for tasks like data mining, where quick results are essential.

Quotes from Members

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

Pros

"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."
"What I really like about this program, is that it is easy to use and easy to configurate."
"It has benefited my organization because it has reduced time to insights."
"The most valuable features of this solution are its ease of use and performance."
"We are satisfied with the performance as it is significantly faster compared to traditional storage options."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"Everything, especially the VMs inside, is pretty fast."
"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"Dell Unity XT offers data integration features."
"There has been no downtime. It has built-in redundancy upon redundancy."
"The Dell EMC unity interface is simple to manage. We manage it by ourselves. We create logs to store data."
"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."
"We use replication for disaster recovery (DR), making our DR process much easier."
"Dell Unity XT is user-friendly and easy to use."
"It's an all-flash Unity, With that compression feature, it's comparable to a hybrid. That is one thing that we definitely like."
"You can add volume and it's automatically registered in VMware."
"We can add a node, we add compute, we add storage, and we've had really good luck with that."
"If you buy the solution for its specific purpose it will work well."
"Feature-wise, it is a good solution allowing users to monitor and simplify their networks. The solution also provides its users with flexibility by enabling them to utilize its extensions."
"It's a very compact device. For a medium-sized business, it's very helpful because the device is efficient and very fast."
"The square footage for doing development is at a premium when dealing with government networks. To be able to put a lot of IOPS in a lot of high-speed performing drives in a very small location which requires very little HVAC with very little power, it is very valuable to us."
"Individual settings you can put on each individual volume, if you want to do that."
"The scalability and being able to implement it quickly."
"The most valuable feature of this solution is its scalability."
 

Cons

"It feels more suitable for small and medium-sized businesses rather than enterprises."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"We need better data deduplication."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"Our use cases require more multi-tenant capabilities and additional VLAN interfaces for separating different customers. We currently use it to provide storage, sometimes shared storage, to different customers, but it is less flexible in comparison to a dedicated solution."
"The tool's portfolio is minimal. It is expensive."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"The tool's pricing is higher than competitors."
"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."
"They can certainly improve in terms of monitoring."
"We need to improve the controller to work as active-active. We also need to improve the snapshot on the Unity site."
"The technical support sometimes takes three to four days to get hardware to facilities. I would rate customer service four out of ten."
"I would like to see more compression and deduplication added to the solution. Today, our compression is about 2:1 and other solutions give us about 4:1 or 5:1."
"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."
"Scalability of this solution could be improved."
"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."
"It would be good to provide administrative access at the root level to be able to do things with the system, if need be."
"They could make the mNode more user-friendly. Now you need to configure and add nodes by CLI and it’s not really easy to manage. If they created a web interface to do the management of the mNode, that would be great!."
"A little better segregation of the multi-tenancy. Right now, it's just VLAN-specific, that's all you can do."
"They could do a file-based NAS: SolidFire NAS-based. It's probably not its niche, but that is our direction, not to use block, and it's block. Solid state block is what it is."
"You don't have business continuity with SolidFire. I think it could be a nice feature to have in the future."
"The technical support is really bad and has to be improved."
"The upgrade process could be better."
"Though it is a stable solution, its users may face some security issues at times...The security provided by the solution is one area that can be improved."
 

Pricing and Cost Advice

"They can tout the functionality and cutting edge technology that they have, but that's where the price tag comes in. The cost is high, but I think as they grow their business and get more customers that it will probably go down a little bit."
"Given its price, Pure is not the first option."
"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."
"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."
"Our licensing fees are $500,000+ USD."
"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."
"As far as the licensing costs, everything is included in the license."
"We bought extended warranties out of the box because our customer has a bad habit of managing warranties."
"It was easy to order. We are a big Dell shop, so it was easy to purchase and get it in place, then up and running."
"Our costs are roughly $200,000 a year."
"The flexibility is important. We still have a lot of customers that have a use case for non-flash, yet you can also build the flash version as well."
"Compression is making a difference towards the amount of hardware that we need to purchase."
"It is shipped with all licensed, included for this product range, no need to buy additional licenses"
"Obtaining a warranty is easy."
"Looking at it based on cost per gigabyte, it's certainly very effective."
"The price of this solution is more expensive than others."
"Based on what I heard from other people, its price was on the higher side."
"On a scale where one is a high price and ten is a low price, I rate the solution between three and four. It is an expensive solution."
"It might be considered expensive, but when evaluating performance, it represents good value online because you pay for what you get."
"We would probably use SolidFire more, except we're getting more bang for our buck with our purchases of ONTAP right now, and the deal we made with NetApp, so it's more of just a cost decision"
