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

"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."
"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."
"It's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."
"The database workloads are pretty fast because I frequently move data from here to there."
"It has good, reliable, fast storage."
"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."
"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."
"I have found Dell EMC Unity XT to be stable."
"It is scalable. We can add additional tools if we need to expand it."
"The most valuable feature is the fast cache with functionality rewrite."
"It's an all-flash Unity, With that compression feature, it's comparable to a hybrid. That is one thing that we definitely like."
"The solution is so easy to manage that I forget it is there."
"The most valuable features include snapshots, Thin Clones, and deduplication and compression."
"We were able to integrate it very quickly with other solutions."
"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 the performance, as well as how you manage performance on the system."
"The simplicity of it."
"Templates are already predefined for it. If you're coding it up, it will take two days. You can pick up a template right there from the API, and it just works for you. Implementation done in 10 minutes."
"Individual settings you can put on each individual volume, if you want to do that."
"The scalability and being able to implement it quickly."
"SolidFire provides seamless performance across your storage system when you need to scale up. Other storage systems do not do that."
"Stability-wise, I rate the solution a ten out of ten."
"Overall performance of the solution."
 

Cons

"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"In terms of what needs improvement, the dashboard and management could be simplified."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"Managing data isn't difficult for me. The performance is usually perfect, but we sometimes have capacity problems."
"There are some challenges with data encryption and reduction."
"I would like to see replication and DR features in the next release of this solution."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"Things that could be improved include one-to-many replication, data deduplication, and asynchronous Fibre Channel replication. It is asynchronous on iSCSI and I would like to have that on the Fibre Channel. Unisphere-wise, I have to log in to each Unity as a unique environment. In VNX, I logged in to the domain and I was logged in to every VNX. So that's missing."
"More integration with VMware would always be helpful, plugins that go directly into the vSphere management. A single pane of glass is always beneficial."
"Dell EMC Unity's competitor, NetApp, has a similar product. However, it has a clustering technology where you can group multiple systems together, then you can move data from one system to another seamlessly. I would like the Unity to do that."
"Currently, the protocol SNMP is not implemented. That's a problem, as we follow this protocol and I can't check the integrity of this equipment."
"​Improve the interface and provide more management capability."
"We had some issues recently because of a bug in the system. We were presenting LANs to the Unity array but I think it caused a disruption to the host. EMC did acknowledge it and provided an alternative way to do it."
"This product lacks deduplication and compression at the current version 4.1.0. LACP is not available for iSCSI either."
"We've also encountered an issue when it comes to migrating to compressed LANs on the Unity, and during the Storage vMotion. It appears that the compression algorithm is overwhelmed, and when it becomes overwhelmed it just stops compressing and writes the raw data to the destination. We later copied internally another Storage vMotion to another compressed LAN and achieved much higher compressions on that internal copy. It would be really nice if there was a way to automatically throttle, as a part of a Storage vMotion, to say, "I want to gain the maximum benefits from the compression algorithm, so throttle back the Storage vMotion to implement 100 percent compression.""
"So feature-wise, I would say more reporting tools that could be merged into it."
"I think there is room for improvement needed with its storage capability. A bigger node is needed."
"SolidFire should start from two nodes instead of the four nodes. That's the only thing. In a lot of solutions, we have to use four nodes, that's the better thing. But as a starting point, two is better. That's why their starting point is expensive."
"The upgrade process could be better."
"The user interface needs to be improved. Much of the client feedback involves comments such as "Oh, it's hard to navigate through.""
"One of the challenges we faced while using SolidFire was that the product line that we were using in our company was discontinued."
"I would like to see integration with the cloud, number one. Being able to spin SolidFire in the cloud."
"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

"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"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."
"Given its price, Pure is not the first option."
"The support cost per array is about $20,000 a year for 24/7 support."
"Our licensing fees are $500,000+ USD."
"With VMware, we pay $300,000 annually."
"The licensing is on a yearly basis."
"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."
"The price of Dell EMC Unity XT is not reasonable. They should lower it because the trend is to move to the cloud. They have to protect their market by giving commercial or financial incentives."
"Our big return of investment is the ability to scale and not add FTE counts nor extra administration."
"As far as licensing goes, I love how VMware works with Dell EMC Unity. It's great. They work hand in hand. They have made it so simple."
"It's the performance combined with the gig-per-dollar value. That combination is superior to other storage options."
"Looking at it based on cost per gigabyte, it's certainly very effective."
"The price is very reasonable."
"It scales, but then you have to buy additional stuff."
"It's an expensive solution, particularly for medium companies. One device costs about 30,000 euros. The support contract is quite expensive as well. We are currently looking for other lower-cost solutions."
"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."
"It might be considered expensive, but when evaluating performance, it represents good value online because you pay for what you get."
"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."
"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"
