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 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."
"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."
"One of the best features is the support, which is excellent."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."
"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"The most valuable feature of this solution is reliability."
"It has the same operating system for both file and block, and it actually simplifies everything. And it's much smaller compared to VNX."
"Purchasing; We worked with a sales rep to purchase our Unity."
"We like the way it integrates with our environment. These features help us use multiple soft applications. The new features of going off the grid and replicating really help us. They give us an advantage versus traditional storage resources."
"Dell Unity XT offers data integration features."
"Integration; We use the product with VMware, and also use it with Syft for home directory and departmental shares."
"The valuable features of Unity include that it's flexible, has a friendly user-interface, and provides good performance."
"The setup and installation procedures are easy."
"It does great deduplication. From a storage perspective, we save money being able to dedupe right on the disk"
"The replication feature provides another functionality to protect your data."
"It is very stable even during multiple power failures."
"I really value deduplication and compression to save space."
"Multi-tiering, positively affects the efficiency of the storage space."
"High availability including non-disruptive updates: We cannot afford downtime windows."
"Good performance for VM environments"
"Integration with VMware"
"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."
 

Cons

"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"In the future, I would like to see integration with enterprise backup systems."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"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."
"Maybe the price can be reduced since the solution is very expensive."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"The tool's portfolio is minimal. It is expensive."
"This product needs to have better integration with enterprise backup solutions and archiving devices."
"This product lacks deduplication and compression at the current version 4.1.0. LACP is not available for iSCSI either."
"Ordering is easy, but the processing site and working with those companies was difficult."
"I would like it to be a little bit easier to contact support. We can contact support, but we have to go through a phone tree. We get routed to different places. I might call support to say that I need a drive replaced and get transferred to three different groups before I get to the group I actually need."
"Scalability of this solution could be improved."
"Dell could improve Unity XT by adding support for NVMe."
"This is a tier-three solution and it gives us what we need for archiving and backups."
"We've got massive issues at the moment with IBM AIX. It's not stable. We have a lot of disk errors, production crashes sometimes."
"If the VNX had embedded encryption, that would be great."
"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 VNX needs to support bigger SSDs. Next generation EMC Unity will do this."
"The administrative console (Navisphere/Unisphere) needs some improvement, especially on their Java-based GUI. The updated version of Java is not compatible."
"The CLI could be better documented, like with VMAX."
"Poor connection to FC."
"The scalability is average because the storage has some hardware limitations and, obviously, operating system limitations."
"Intel Xeon processors with under 2 GHz processing speeds could be replaced with more recent ones."
 

Pricing and Cost Advice

"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."
"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."
"Our licensing fees are $500,000+ USD."
"With VMware, we pay $300,000 annually."
"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."
"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."
"The product is expensive."
"The support cost per array is about $20,000 a year for 24/7 support."
"This product is cheaper than the EMC VNX solution. It is good for small businesses."
"From an ROI perspective, I'll put it this way: When we've tried to buy other SANs, the Unity ROI makes it impossible to buy them. So usually, the only time we buy another SAN is when the ROI isn't a factor, because Unity can't do the job. From an ROI perspective, it's great because it beats everything else out. We've tried to look at other options but, at the end of the day, when you price it out, the Unity wins."
"Pricing is as high as it has ever been for EMC."
"What they really like is the easy licensing now - Dell EMC has caught up to a lot of their competitors - based on not having to charge for everything, and they can get everything in one bundle."
"The price of the solution should be less expensive. However, at some point, you need to pay for facility and performance."
"It's the performance combined with the gig-per-dollar value. That combination is superior to other storage options."
"Compression is making a difference towards the amount of hardware that we need to purchase."
"The price in our country is very expensive and some of our customers opt for lower-cost alternatives."
"​Reducing dependency on JavaServer Pages​ (JSP) could improve the administrative overhead.​"
"The initial pricing and licensing are reasonable, the yearly EMC is more expensive"
"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."
"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."
"Over time, VNX has become pricier than its competitors, and we have turned enthusiastically to Unity."

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.
