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

"It has good, reliable, fast storage."
"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"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."
"The solution is scalable."
"It has benefited my organization because it has reduced time to insights."
"The best features of Pure FlashArray X NVMe include the volume snapshot capabilities, which allow us to save most of the storage space by volume snapshots periodically."
"Speed has definitely been a big improvement for us; we were running a bunch of iSCSI to EMC VNX and that had a gigabyte bottleneck, and now, since we're running through a true fiber channel to the Pure array, we're getting 32-gigabyte bandwidth, which means the speed and accessibility for our users and our customers have definitely improved."
"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"For our customers, the benefits are that it's not too expensive and it has almost all of the features from the beginning."
"I cannot stress enough how simple and easy it is to set up and use and manage."
"It's easy to manage. We access it and manage it through Unisphere and have had no issues. We're able to provision storage, create consistency groups, create RDMs for our virtual machines. Creating it through Unisphere, it automatically adds the data store on the VMware side and rescans the LUNS. We just have to add and configure the storage in one place and it takes care of everything, which is very handy."
"The hardware itself, it differs from Compellent and differs from the VNX before it. It doesn't have a separate file harbor that goes with it, there are no separate NAS heads. It's 2U, you have file and block storage, so you get a quite a lot of services for a small footprint."
"Compared to older generations of arrays there is quite an improvement, compared to the older VNXs, for example, and for our purposes, we find Unity simple to use."
"The solution overall has high performance."
"What I found most valuable from Dell EMC Unity XT is its easy management through its multi-cloud support."
"With all-flash it should be able to scale. You probably just need one 4U device and you have terabytes of space."
"From my point of view, the configuration that I can sell is restricted to the EMC best practices. It is hard to make a mistake in a solution. It means the configuration has good performance and scalability options."
"Stability has been rock solid, as we have been running both units for over two years with no major problems."
"It is a good product with a simple setup and easy administration."
"It’s very stable in all the years I've worked with it, I know it’s stable and the support is there."
"It is very stable, even during multiple power failures."
"Multi-tiering, positively affects the efficiency of the storage space."
"EMC storage has the best performance and functions."
"Since implementing VNX, we achieved a 10 times increase in the performance for its end users."
 

Cons

"I would like to see replication and DR features in the next release of this solution."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"I'd like to see the product implement active replication for vehicles such as VMware."
"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."
"It feels more suitable for small and medium-sized businesses rather than enterprises."
"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."
"I would like to see some AI features that would allow arrays to intelligently identify threats or unusual behavior in the data pattern and give an alert."
"It is expensive, and the pricing could be better."
"Scalability of this solution could be improved."
"There are features still to come, like compression and deduplication on hybrid platforms, VDM improvements to be developed for NAS environments, and also improvements in the “self-migration” tools to push or pool information (to assist the migrations to and mostly from third-party arrays)."
"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."
"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.""
"The VNX reporting is much more granular, versus the Unity reporting."
"Licensing costs could be reduced."
"The Host LUN ID is sequential by access in the hosts. When one LUN needs access by many hosts (for cluster purposes), in some cases the Host LUN ID remains different on each host."
"They don’t quite provide enough security in the data centre."
"Oracle is never the cheaper solution. Compared to others, it is always among the most expensive."
"Over time, VNX has become pricier than its competitors, and we have turned enthusiastically to Unity."
"EMC VNX needs to support bigger SSDs. Next generation EMC Unity will do this."
"Over time, VNX has become pricier than its competitors, and we have turned enthusiastically to Unity."
"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."
"I do not recommend the Gen 1 VNX to anyone in this day and age."
"We actually had data loss from too many simultaneous drive failures on the 7500."
 

Pricing and Cost Advice

"Our licensing fees are $500,000+ USD."
"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 licensing is on a yearly basis."
"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."
"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."
"We pay approximately $50,000 USD per year in licensing fees."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"The tool's pricing is cheap; I rate it a six to seven out of ten. Most of our sales are not subscription-based. We sell the hardware, and customers keep using it. They only renew the service part annually. The support can be a bit pricey, but the solution is more cost-effective than anything else out there."
"Compression is making a difference towards the amount of hardware that we need to purchase."
"While it has a good price to start, they could always make it cheaper."
"Licensing is fine. We worked with a sales rep to purchase our Unity."
"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."
"For costing, you have to have a budget in mind because SANs can be fairly expensive and EMC offers a wide range of products."
"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."
"When you look at what Dell EMC is compared to, like NetApp, they're all priced pretty similarly. I think the pricing of the hybrid model is good."
"We have to apply for a license for each system."
"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."
"​Reducing dependency on JavaServer Pages​ (JSP) could improve the administrative overhead.​"
"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."
"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 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.
