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 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."
"If a company is looking for an All-Flash Tier and they need extreme performance for individual workloads, Pure's the way to go, over something like a SolidFire."
"It has drastically improved the performance of our high-end Oracle databases and allows us the ability to replication to a DR location with ease."
"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."
"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."
"Using this solution has benefitted us operationally by making us more efficient."
"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"What we've seen on the Xs, and the Pures in general, is that we can scale way beyond what we need to without any degradation in performance."
"It's easy for us to use because we use other solutions which are built for Unity, like VMware, which are recovery points. They work with the Dell EMC Unity system, as these products integrate well in our environment."
"The scalability is really good now that they have the Dynamic Pools. We don't always have the money to buy complete write sets when we have to expand the storage, so now with the Dynamic Pools we can add disks on the go."
"For our customers, the benefits are that it's not too expensive and it has almost all of the features from the beginning."
"It is lightning fast, low on power and heat, and has a small footprint with great performance."
"The solution is extremely functional for the price that we pay for it."
"Dell Unity XT is user-friendly and easy to use."
"A lot of the Unisphere interfaces are greatly improved in terms of monitoring capabilities, alerting, and ease of use. Setting up the storage and the file system are all just a few clicks away."
"Purchasing; We worked with a sales rep to purchase our Unity."
"EMC storage has the best performance and functions."
"I think it's a good solution; it has many benefits and features that are of interest for many customers."
"The stability of the hardware, and its ability to manage millions of IOPS, provides great comfort to system administrators, IT managers and CIOs."
"The implementation of both block and file system storage in a single GUI provides is better situated than most other storages."
"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."
"One thing I would like to explicitly mention here is the EMC support; it is by far one of the best supports you will ever get in comparison with any vendor."
"The most valuable feature is the auto-tiering, which helps in the speed of data access."
"Customer Service: It's great. Technical Support: It's great."
 

Cons

"The solution should improve its logon requirements."
"One area that I haven't been sold on yet is the POD replication."
"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."
"In terms of what needs improvement, the dashboard and management could be simplified."
"It feels more suitable for small and medium-sized businesses rather than enterprises."
"In the future, I would like to see integration with enterprise backup systems."
"I'd like to see the product implement active replication for vehicles such as VMware."
"In the future, I would like to see integration with enterprise backup systems."
"It needs more functionality and the ability to move across more landscapes."
"Scalability is not good. We have a Unity 300, now we have to do a data-in-place conversion for the next upgrade because only 150 slots are supported, not drives, only slots."
"The biggest one for us, and the reason we don't use it more, is that we can't throttle the replication speed."
"This product needs to have better integration with enterprise backup solutions and archiving devices."
"Improve the administrative user interface so it is easier to work with. Currently, a simple task, such as removing a host from 100 LUNS, takes a lot of time. If they could improve LUN to host model to be more like the EMC VPLEX, for example, it would be great."
"I'm not sure if it has a single pane of glass management console. That would be something we would like to see."
"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."
"This solution would be improved with the addition of flexible raid volumes."
"Poor connection to FC."
"They may change the disks from NL-SAS to Flash, but it would be costlier for customers."
"The administrative console (Navisphere/Unisphere) needs some improvement, especially on their Java-based GUI. The updated version of Java is not compatible."
"HP EVA and once NetApp, but they both had slow performance and a lack of features so we switched."
"Poor connection to FC."
"The scalability is average because the storage has some hardware limitations and, obviously, operating system limitations."
"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."
"Customer Service: I don't like the way EMC's Powerlink support is behind a wall."
 

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."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"The product is expensive."
"Given its price, Pure is not the first option."
"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."
"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."
"It is an average priced solution."
"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."
"Licensing is a little bit confusing. Going through everything with them, there are a lot of line items to go over. Every single thing is broken down into a line item, and it starts to get really confusing in terms of what we're actually purchasing when it comes to the product."
"The pricing is competitive. We miss some of the feature functionality that we had with the XtremeIOs but it's certainly suitable for the purpose."
"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."
"Obtaining a warranty is easy."
"The price of Dell Unity XT could improve. However, it is a one-time purchase."
"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."
"The initial pricing and licensing are reasonable. Yearly EMC is more expensive."
"​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."
"Over time, VNX has become pricier than its competitors, and we have turned enthusiastically to Unity."
"The initial pricing and licensing are reasonable, the 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."

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.
