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.

The Nimble CS-Series has proven to be reliable with 100% uptime
When we started the process of looking for a SAN vendor I had four primary criteria: reliability, performance, cost, and simplicity. We were really looking for a unicorn and were fully expected to have to make compromises in one of those areas. The Nimble CS-Series was recommended by our solutions provider, and we were blown away. Not only was it the most affordable option, but it was the easiest to deploy, had the best performance, and has proven to be reliable with 100% uptime.

Quotes from Members

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

Pros

"The latency is good."
"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"It has good, reliable, and fast storage."
"FlashArray has some fresh efficiency features, I've never seen a storage solution with a compression rating this high before, it's at least 4-to-1 on Oracle databases, it's the best flash storage for Oracle."
"We were able to save a ton of data center space with density ratios we've never seen before with hardware, and with Pure, we immediately saw value in the density ratios that we would be able to achieve, the performance, the scalability, and the support."
"Its speed is superior to our existing Unity x00 model and it has performed substantially better than our x00 model and a little bit better than our x50 model."
"The most valuable feature of this solution is reliability."
"Everything, especially the VMs inside, is pretty fast."
"It is simple to use and easy to manage. We don't touch it after we set it up."
"The most valuable aspect of this solution is that it's a single block, a complete block that includes both NAS and SAN."
"It gives me the flexibility with its ability to replicate to itself and the ability to use the Dell EMC Cloud as an option. That's always sitting there and waiting if we need it."
"Unity provides a complete storage solution for VMware on a Wintel Windows box for various applications, such as SQL or Patron Databases."
"The most valuable feature is the fast cache with functionality rewrite."
"Scalability is good."
"It's easy to handle for administrators and it's a unified system."
"Dell EMC's technical support is perfect."
"It is very stable even during multiple power failures."
"The implementation of both block and file system storage in a single GUI provides is better situated than most other storages."
"The most valuable feature is the auto-tiering, which helps in the speed of data access."
"It is a good product with a simple setup and easy administration."
"Good performance for VM environments"
"If you have a banking and finance domain, then go for EMC products as they offer better performance and scalability."
"Technical support is good."
"I really value deduplication and compression to save space."
 

Cons

"In terms of what needs improvement, the dashboard and management could be simplified."
"They could add more support for file storage and different types of storage."
"In the future, I would like to see integration with enterprise backup systems."
"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."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"Managing data isn't difficult for me. The performance is usually perfect, but we sometimes have capacity problems."
"The tool's portfolio is minimal. It is expensive."
"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."
"Licensing has been quite difficult. It doesn't always auto-license. About half the time, when I provision one, I have to contact Service to get a license, or even go to our account manager to help get it straightened out."
"It's not as reliable as it should be, I think it was probably released a little early. We've had production problems with customers, and there are still some challenges at scale as well. Compression is a problem for the system. Once you enable dedupe and compression, the performance of the system, the capability, halves... It has to be right-sized and sized for compression, but even with that, because there are only two storage processors, you're ending up at almost 40 percent usage."
"The technical support sometimes takes three to four days to get hardware to facilities. I would rate customer service four out of ten."
"They're slow to implement new innovation with their product. EMC doesn't really innovate; they just sit there and wait for other people to innovate, and then they just copy."
"It would be nice to have been able to easily move off our old VNX system to this system. The process is very manual."
"Yes, we had an issue in January with a Service Processor rebooting unexpectedly."
"Definitely the biggest requirement is deduplication. The EMC Unity Platform doesn’t have this feature, yet it was a part of the predecessor VNX series."
"The management software used for the VNX is Unicenter. While it is an improvement over Navicenter, used in older EMC SANs, it still feels outdated in comparison to other SAN management software."
"EMC wasn't able to fix the issue, so they had to stop using snapshots."
"EMC VNX needs to support bigger SSD and the Next Generation EMC Unity does this."
"We encountered scalability as it is limited by backend slots, and NAS performance is significantly reduced when scaling."
"We have had some scalability issues. Scalability options are limited due to the supported SSDs."
"VNX can improve by offering flexible upgrade options. It's not possible to add a single HDD to a current array and there are fixed rules to make upgrades."
"EMC products are costly when compared to other vendors such HP, Hitachi, Dell, and NetApp."
"Over time, VNX has become pricier than its competitors, and we have turned enthusiastically to Unity."
 

Pricing and Cost Advice

"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."
"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."
"As far as the licensing costs, everything is included in the license."
"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."
"Given its price, Pure is not the first option."
"The product is expensive."
"Most licenses for the solution are free but upgrades are available when adding additional software or storage."
"The only improvement would be a lower cost per unit/disks, however on the whole we are very pleased with this product."
"From a pricing perspective, this solution is comparable to others on the market."
"There is an annual charge for the license of this product. It has better pricing than its competitor: Pure Storage."
"Because of the attractive price, we were able to get rid of more expensive arrays, standardize, and get rid of a lot of spinning disks. We also got rid of more expensive flash that we weren't properly utilizing."
"We have to apply for a license for each system."
"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."
"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."
"Make sure you understand how the licensing works and that you are getting the right set of licenses if you need array-to-array replication."
"Over time, VNX has become pricier than its competitors, and we have turned enthusiastically to Unity."
"The initial pricing and licensing are reasonable, the yearly EMC is more expensive"
"While EMC tends to be on the expensive side, the stability and support of their products are top-notch and I feel are worth the cost."
"The initial pricing and licensing are reasonable. Yearly EMC is more expensive."
"Pricing is somewhat higher, especially in Zambia, perhaps due to the low sales volume."
"​Reducing dependency on JavaServer Pages​ (JSP) could improve the administrative overhead.​"

The VNX range is older and is being phased out. I think you mean VNX 5200? That said the Unity 400 is the better investment as it is newer, cheaper to support, faster, and with higher capacity and bigger supported file system size.
