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

"I appreciate the performance."
"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"Overall stability is very good. It is a very stable solution."
"One of the best features is the support, which is excellent."
"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 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."
"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."
"On a scale of one to ten, I rate Pure FlashArray as ten."
"All-flash array eliminates all the overhead of tiering and a lot of the data structuring overhead involved."
"It is very stable."
"The All-Flash models are pretty fast for the vast majority of our remote workloads."
"We run about 100 virtual servers on it. We have about 100 users accessing the file shares from there, and I've seen no problem with that. We have about a 10GB backbone. Whatever we throw at it, it hasn't shown any sign of weakness or anything. It's been really good."
"The ease of management and “user-friendly” management environment (GUI)."
"In the hybrid version, I would say they are fast. They have fully automated storage tiering. In the all-flash version, higher performance, compression, data replication."
"Inline data reduction is pretty impressive."
"Performance is a top feature."
"High availability including non-disruptive updates: We cannot afford downtime windows."
"FAST (auto-tiering): Doesn't require configuration and is managed by the array itself."
"Good performance for VM environments"
"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."
"It is very stable, even during multiple power failures."
"One of the best features of the VNX is the ability to combine drives of different types into a virtual Storage Pool. By combining small but fast flash drives, SAS drives, and high-capacity but slower NL-SAS drives, the VNX can intelligently move data to the different tiers of storage based on usage."
"The most valuable feature is the tight VMware integration, due to the migration from bare metal to virtualized environments and then on to the cloud."
"Integration with VMware"
 

Cons

"The tool's portfolio is minimal. It is expensive."
"The tool's pricing is higher than competitors."
"Adding some functions to the product would be beneficial."
"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."
"Maybe the price can be reduced since the solution is very expensive."
"The UI for this solution needs to be improved."
"In the future, I would like to see integration with enterprise backup systems."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"This product needs to have better integration with enterprise backup solutions and archiving devices."
"Our customers are mostly happy with Unity except for the price. We primarily sell to enterprise companies because small companies cannot afford it."
"The monitoring part could be better. With EMC storage systems - or Unity and VPLEX, because I'm using them, for the moment - the monitoring part is very difficult. They should improve this to have a better reporting system."
"Dell could improve Unity XT by adding support for NVMe."
"The initial setup is not so straightforward if you don't have experience with storage arrays."
"We had one incident with a memory leak that led to controller reboot. Although it had no impact, when such things happens the storage should be more aware of it, send alerts, and propose corrective actions."
"Scalability for the 650F is good, but I was expecting a little bit more."
"We cannot connect directly with Dell due to sanctions."
"EMC VNX needs to support bigger SSDs. Next generation EMC Unity will do this."
"There is an easy replication process between distinct data centers via VPLEX and/or RPA. But I hope in the future that EMC/Dell could replicate this with other types of storage."
"If the VNX had embedded encryption, that would be great."
"It would be very helpful to get an automated report that shows you the size of the checkpoints and get warnings when a checkpoint is reaching either maximum capacity per a file system or hitting the ceiling on the SavVol pool consumption."
"The administrative console (Navisphere/Unisphere) needs some improvement, especially on their Java-based GUI. The updated version of Java is not compatible."
"EMC VNX needs to support bigger SSD and the Next Generation EMC Unity does this."
"Based on our workloads, we see repeatedly in performance reports that the built-in controller (SP) cache of our VNX model is not sufficiently large, resulting in forced cache flushing."
"The scalability is average because the storage has some hardware limitations and, obviously, operating system limitations."
 

Pricing and Cost Advice

"The licensing is on a yearly basis."
"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."
"The product is expensive."
"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."
"As far as the licensing costs, everything is included in the license."
"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 ROI is right where we need it to be. It's a reasonably priced array."
"It is an average priced solution."
"The price of Dell Unity XT is reasonable. However, if you are buying a custom solution, it can come at a considerable price."
"The price of Dell Unity XT could improve. However, it is a one-time purchase."
"The price in our country is very expensive and some of our customers opt for lower-cost alternatives."
"We looked at HPE Nimble but the price of the Unity XT was very good compared to the competition."
"Looking at it based on cost per gigabyte, it's certainly very effective."
"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."
"​Reducing dependency on JavaServer Pages​ (JSP) could improve the administrative overhead.​"
"The initial pricing and licensing are reasonable, the yearly EMC is more expensive"
"Over time, VNX has become pricier than its competitors, and we have turned enthusiastically to Unity."
"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."
"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."

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.
