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

"One of the best features is the support, which is excellent."
"The tool's valuable features are speed, security, data compression, and reliability. Its data compression feature is the best that we have ever seen. It helps us to save money and resources."
"The initial setup was extremely simple and straightforward."
"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"Being able to have broken files on-site on the same appliance is quite useful."
"We generally always advise people to make the choice to go with Pure Storage because they won't regret it."
"The Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."
"Replication and ease of storage setup for block LUN’s and VMware."
"After migration to Unity 300F, we were able to put more DBs on flash, reducing latency. The results were visible in the front-end systems, and all users noticed the improvement."
"The solution allows for easy, useful replication with good features for VPLEX and VIVO."
"We have adopted the all-flash array; it eliminates all the overhead of tiering and a lot of the data structuring overhead involved, and it gives us a lot of operational efficiencies."
"It saves us time, it does not require a lot of admin from us."
"There has been no downtime. It has built-in redundancy upon redundancy."
"We hear from our customers that it is stable."
"Ease of use is probably number one, compared to the previous storage that we've had. Easy scalability, easy set up. Compared to everything else, the Unity is, well, you could call it child's play. As long as you know what you're doing storage-wise, Unity is really easy to use."
"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 is very stable even during multiple power failures."
"The replicating of the entire storage unit to a different location was a very useful function."
"It is very stable even during multiple power failures."
"Good performance for VM environments"
"In one cabinet, we have many environments: VMware, Oracle, Adabas, NAS (CIFS and NFS resources), and mix disks on tier configurations Tier configuration with different disks (SAS, SATA, Flash) The software for management is very user-friendly Snapshots for backup and refresh development on test environments"
"Stability has been rock solid, as we have been running both units for over two years with no major problems."
"The implementation of both block and file system storage in a single GUI provides is better situated than most other storages."
 

Cons

"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"The tool's pricing is higher than competitors."
"It feels more suitable for small and medium-sized businesses rather than enterprises."
"There is room for improvement in the pricing of the product."
"The software layer has to improve."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"It needs more functionality and the ability to move across more landscapes."
"In terms of what could be improved, I would say the deduplication part, because for large deduplications, you need an extra appliance to do it in order to avoid having problems in performance."
"The EMC VNX Virtual Data Mover (VDM) software needs more improvement."
"Scalability for the 650F is good, but I was expecting a little bit more."
"What I'd like to see is a little more detail on the networking side. I can go into where it's showing me the replication, but when I go into the network it just gives me broad-based information."
"The interface can be a little challenging for someone new."
"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."
"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."
"Intel Xeon processors with under 2 GHz processing speeds could be replaced with more recent ones."
"The administrative console (Navisphere/Unisphere) needs some improvement, especially on their Java-based GUI. The updated version of Java is not compatible."
"Customer Service: I don't like the way EMC's Powerlink support is behind a wall."
"EMC pricing is too expensive, like the Apple brand iPhone in the cellphone market."
"Over time, VNX has become pricier than its competitors, and we have turned enthusiastically to Unity."
"You need a lot of licenses in order to use this product, which makes the product expensive; the maintenance contract price also increases significantly every year."
"The scalability is average because the storage has some hardware limitations and, obviously, operating system limitations."
"VNX can improve by offering flexible upgrade options."
 

Pricing and Cost Advice

"The product is expensive."
"Given its price, Pure is not the first option."
"As far as the licensing costs, everything is included in the license."
"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."
"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."
"We pay approximately $50,000 USD per year in licensing fees."
"The support cost per array is about $20,000 a year for 24/7 support."
"As far as licensing goes, I love how VMware works with Dell EMC Unity. It's great. They work hand in hand. They have made it so simple."
"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."
"Pricing is as high as it has ever been for EMC."
"It is shipped with all licensed, included for this product range, no need to buy additional licenses"
"It is priced at around or under $50,000."
"Go with the virtual appliance versus the hardware."
"The price of the solution should be less expensive. However, at some point, you need to pay for facility and performance."
"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 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."
"​Reducing dependency on JavaServer Pages​ (JSP) could improve the administrative overhead.​"
"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, the yearly EMC is more expensive"

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.
