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, and fast storage."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"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 system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"Technical support has been helpful and responsive."
"The cost for Pure may be high, but the reliability and scalability make it well worth the money."
"After the testing, it was clear to us that the Pure FlashArray X NVMe was the easiest to manage and configure and had the best performance that we had seen in all the arrays."
"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."
"Setup is simple, but at the expense of key management features."
"The solution allows for easy, useful replication with good features for VPLEX and VIVO."
"Integration; We use the product with VMware, and also use it with Syft for home directory and departmental shares."
"We hear from our customers that it is stable."
"Dell Unity XT offers data integration features."
"The valuable features of Unity include that it's flexible, has a friendly user-interface, and provides good performance."
"It’s helped with the overall stability of our VMware environment."
"My storage team likes Unity's replication features. Three-site replication is a unique feature that EMC offers us."
"FAST auto-tiering is a great feature."
"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."
"It’s amazing, you can add and stack, and add more elements."
"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."
"It has a good, high-level of storage."
"High availability including non-disruptive updates: We cannot afford downtime windows."
"VNX 5200 works well with a medium VMware cluster, has good performance, and enables hardware disk replication."
"I have worked on CLARiiON and all series of VNX."
 

Cons

"We would like to see VNC integration or be able to use Pure Storage with VNC."
"The tool's portfolio is minimal. It is expensive."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"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."
"There is room for improvement in the pricing of the product."
"The UI for this solution needs to be improved."
"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."
"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 biggest one for us, and the reason we don't use it more, is that we can't throttle the replication speed."
"It should be lighter. It takes up a ton of rack space."
"Recently, they released products, sometimes without proper testing, it seems."
"This product needs to have better integration with enterprise backup solutions and archiving devices."
"Dell Unity XT’s price needs improvement."
"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."
"The payment account area."
"I haven't seen the roadmap for this solution."
"HP EVA and once NetApp, but they both had slow performance and a lack of features so we switched."
"They don’t quite provide enough security in the data centre."
"Over time, VNX has become pricier than its competitors, and we have turned enthusiastically to Unity."
"There is no easy way to defrag a RAID group. It would be nice to be able to reduce the size of a storage pool if the storage is not needed anymore."
"We have had some scalability issues. Scalability options are limited due to the supported SSDs."
"I do not recommend the Gen 1 VNX to anyone in this day and age."
"Storage processor architect for real active/active HA ASIC based functions are needed"
"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."
"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."
"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."
"With VMware, we pay $300,000 annually."
"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."
"We pay approximately $50,000 USD per year in licensing fees."
"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."
"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."
"I rate Dell Unity XT’s pricing a nine out of ten."
"The price of Dell EMC Unity XT is higher compared to other solutions. The price should be less expensive."
"We have to apply for a license for each system."
"The product’s pricing should be improved."
"Its biggest valuable feature is its price point for the amount of storage and performance you get. It's a sweet spot. It's cheaper than the other SANs out there, but performs well enough. It fits that nice, middle-ground portfolio."
"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."
"For costing, you have to have a budget in mind because SANs can be fairly expensive and EMC offers a wide range of products."
"It scales, but then you have to buy additional stuff."
"The initial pricing and licensing are reasonable. Yearly EMC is more expensive."
"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."
"​Reducing dependency on JavaServer Pages​ (JSP) could improve the administrative overhead.​"
"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.
