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 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."
"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"On a scale of one to ten, I rate Pure FlashArray as ten."
"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."
"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"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 latency is good."
"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"It is simple to use and easy to manage. We don't touch it after we set it up."
"It's a much smaller footprint than our older storage arrays, which take up some six tiles, a lot of space in the data center. The Unity's are a lot smaller, and they're a lot faster."
"On a scale from one to 10, I'd probably give EMC customer support an 11. It's been really good. We do have premium support, which means if we have a problem, it gets solved really quickly."
"It is easy to manage. A lot of the system manages itself."
"The technical support is very professional and provides quick responses."
"It is easy to scale, maintain, and manage."
"The feature that I have found most valuable is the unified storage. Also, its capabilities for block-access, file access, and the center box."
"Their support cases are all handed through the portal. The support contacts me when they need to do upgrades. It has been great. It's all very well-handled, scheduled, and performed."
"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"
"The most valuable feature is the auto-tiering, which helps in the speed of data access."
"FAST (auto-tiering): Doesn't require configuration and is managed by the array itself."
"The replication feature provides another functionality to protect your data."
"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 implementation of both block and file system storage in a single GUI provides is better situated than most other storages."
 

Cons

"Managing data isn't difficult for me. The performance is usually perfect, but we sometimes have capacity problems."
"I would like to see replication and DR features in the next release of this solution."
"It feels more suitable for small and medium-sized businesses rather than enterprises."
"They could add more support for file storage and different types of storage."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."
"There is an issue with data duplication occurring on the flash memory. It should be improved. Timely updates and upgrades to the latest versions would be great."
"The NAS capabilities of Unity - I have to say there are a lot of things I miss. For example, deduplication for hybrid. I have tons of customers with VNX and dedupe. These customers achieve around 50% dedupe efficiency and they mostly use them for archive. If you're talking about 50TB of NAS, which is stored in a 25TB repository, which is very economical, and you can not provide that in a Unity hybrid box, you have problems."
"Compression and block deduplication on non-all-flash solutions."
"​Improve the interface and provide more management capability."
"There is no de-duplication. Unity used to be Bionics, which had de-duplication; however, in Dell Unity XT, the de-duplication was deprecated and is no longer available."
"It would be better if there were more integrations."
"The product’s pricing should be improved."
"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 CLI could be better documented, like with VMAX."
"Poor connection to FC."
"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."
"If the VNX had embedded encryption, that would be great."
"EMC VNX needs to support bigger SSDs. Next generation EMC Unity will do 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."
"EMC VNX needs to support bigger SSD and the Next Generation EMC Unity does this."
"Intel Xeon processors with under 2 GHz processing speeds could be replaced with more recent ones."
 

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."
"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."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"The licensing is on a yearly basis."
"We pay approximately $50,000 USD per year in licensing fees."
"Given its price, Pure is not the first option."
"Our licensing fees are $500,000+ USD."
"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 pricing was quite okay compared to others. We probably got it cheaper because we were the first ones out of the gate, but I would say that it's good value for the money."
"The product’s pricing should be improved."
"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."
"The price of Dell Unity XT could improve. However, it is a one-time purchase."
"We purchased a five-year warranty."
"Compared to other EMC platforms, Unity is nice because it is all-inclusive, in terms of the licensing model. That's unique for them, compared to other manufacturers. It is beneficial. We could use replication, native, right out-of-the-box."
"We bought extended warranties out of the box because our customer has a bad habit of managing warranties."
"Pricing is as high as it has ever been for EMC."
"The initial pricing and licensing are reasonable. Yearly EMC is more expensive."
"Over time, VNX has become pricier than its competitors, and we have turned enthusiastically to Unity."
"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.​"
"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, the yearly EMC is more expensive"
"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."

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.
