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

"Speed has definitely been a big improvement for us; we were running a bunch of iSCSI to EMC VNX and that had a gigabyte bottleneck, and now, since we're running through a true fiber channel to the Pure array, we're getting 32-gigabyte bandwidth, which means the speed and accessibility for our users and our customers have definitely improved."
"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"We generally always advise people to make the choice to go with Pure Storage because they won't regret it."
"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."
"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."
"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"Overall stability is very good."
"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."
"The most valuable feature is that the solution is a hybrid system, so you can do both block and file storage."
"The most valuable features of Dell Unity XT are the data compression for all of our VMs up to four times and the performance is good."
"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."
"We have simplified it down to where we're using one storage pool inside the Unity, whereas on the VNX, we had multiple storage pools. This has simplified that aspect for us. It would depend on each organization. We're heavy into VMware and this ties into it so simply. It's made it a lot easier for us. I create a datastore inside Unity, it just shows up in VMware. I love that tie-in."
"It is definitely one of the most robust, solid, well-performing products that I have dealt with, and it is set it and forget it, which is wonderful for my peace of mind."
"The way it takes the Snaps, that is one of the best features. Snapshot performance is what is key in the Unity, compared to a traditional VNX."
"Once it is set up, it is definitely easy to manage."
"It hasn't missed a beat; we haven't had any issues with it whatsoever, speed has been great, it does everything we need, there has been no downtime, and with built-in redundancy upon redundancy I feel very confident with it."
"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."
"EMC storage has the best performance and functions."
"If you are looking for a stable, powerful and effective entry level SAN that you can provision on your own for a small environment or a small office/remote office situation - this is definitely the product for you."
"Multi-tiering, positively affects the efficiency of the storage space."
"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 replication feature provides another functionality to protect your data."
"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"
"It’s amazing, you can add and stack, and add more elements."
 

Cons

"In the next release, I would like to see real-time analytics for further insight into consumption models."
"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."
"It feels more suitable for small and medium-sized businesses rather than enterprises."
"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."
"I'd like to see the product implement active replication for vehicles such as VMware."
"The software layer has to improve."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"In the future, I would like to see integration with enterprise backup systems."
"Maybe deduplication would be something that would be better to have. Also, it's a fairly new management interface, so work is still being done on that. But compared to other vendors and previous EMC storage, the Unity is really good."
"​Improve the interface and provide more management capability."
"Last (and I understand that it has a low chance of being implemented) the copy services currently are redirect on write. It would be great if the administrator could choose between redirect on write and copy on write, when configuring copy job."
"They should have more wizards for customers so they can do more of the self-service types of functions, in terms of upgrades and patching, although it's pretty easy right now."
"When I see other products—like HP, Huawei, and Lenovo—from competitors, I have seen a lot of disadvantages with EMC, price-wise."
"What we noticed was that the SP utilization is quite high, although the main load is on a VMAX."
"Perhaps if they added more 10GB ports to the back of the system, so you have more IOPS out of the box itself to the network, that would help."
"I have a problem because between the Unity XT and the PowerMax, sometimes we need another product between these two products. There could be better integrated and the capacity of the size could be larger."
"We have had some scalability issues. Scalability options are limited due to the supported SSDs."
"Due to very complex structure and sophisticated architecture, it needs experts for trivial troubleshooting also."
"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."
"The administrative console (Navisphere/Unisphere) needs some improvement, especially on their Java-based GUI. The updated version of Java is not compatible."
"So far we haven't had many issues with the VNX. However, the Data Mover (that manages CIFS/NFS) part needs some improvements."
"Make major changes to the file services, Celera, do something like a lite version."
"They may change the disks from NL-SAS to Flash, but it would be costlier for customers."
"If the VNX had embedded encryption, that would be great."
 

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."
"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."
"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."
"With VMware, we pay $300,000 annually."
"The support cost per array is about $20,000 a year for 24/7 support."
"We pay approximately $50,000 USD per year in licensing fees."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"Obtaining a warranty is easy."
"This solution is a good price for what you get."
"It is an average priced solution."
"Because of the attractive price, we were able to get rid of more expensive arrays, standardize, and get rid of a lot of spinning disks. We also got rid of more expensive flash that we weren't properly utilizing."
"When you look at what Dell EMC is compared to, like NetApp, they're all priced pretty similarly. I think the pricing of the hybrid model is good."
"The Dell EMC Data Protection license covers everything, like a one stop shop. All our options are covered."
"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."
"Pricing is as high as it has ever been for EMC."
"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."
"Pricing is somewhat higher, especially in Zambia, perhaps due to the low sales volume."
"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."
"​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."
"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 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.
