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 administration and the stability are very good."
"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."
"Overall stability is very good. It is a very stable solution."
"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 has good, reliable, and fast storage."
"What I really like about this program, is that it is easy to use and easy to configurate."
"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"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."
"User friendly interface"
"Pricing is relatively good compared to other vendors with the same specifications."
"We put the Unity on one of the file servers and the backup performance improved quite a lot."
"It is a hassle-free storage environment that helps us manage our hardware, the upgrades are helpful, and it makes our organization a more productive environment."
"VMware integration: Grants both the Storage and Virtual Administrator the ability to create and mount datastores, or even to check how much space each VM is consuming."
"Since we have deployed, this has easily saved us close to about $300,000 easily."
"EMC is known for its reliability This product is good It is easy to install and maintain It operates with low maintenance and manpower costs"
"It is a workhorse and will run even demanding workloads."
"It’s amazing, you can add and stack, and add more elements."
"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."
"I have worked on CLARiiON and all series of VNX."
"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."
"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."
"It is a great product: scalable, reliable, and robust."
"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"
"I really value deduplication and compression to save space."
 

Cons

"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"We need better data deduplication."
"The software layer has to improve."
"In terms of what needs improvement, the dashboard and management could be simplified."
"It is on the expensive side."
"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."
"The software layer has to improve."
"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."
"For us, it was expensive, but it was of value to us. However, I wouldn't go through that again."
"In some countries, spare part availability is an issue for us."
"​Improve the interface and provide more management capability."
"Firmware Upgrades in EMC Unity require you to manually download OS and Drive firmware, this should be integrated (Nimble does this). When you order an EMC Unity, you have to specify the block size. This is weird for me and even weirder that you cannot change this afterwards, you should be able to specify per LUN/datastore (Nimble does this as well)."
"The only issue is with the product's scalability because it's not as scalable as the other polished tools in the market."
"The monitoring part could be better. With EMC storage systems - or Unity and VPLEX, because I'm using them, for the moment - the monitoring part is very difficult."
"We have only used tech support to replace drives that have gone bad. But our experience has not been so good."
"There is no de-duplication. Unity used to be Bionics, which had de-duplication; however, in Dell Unity XT, the de-duplication was deprecated and is no longer available."
"The performance impact snapshotting had on the cluster was enormous. The entire cluster performance took a performance impact of about 30% as soon as we created one snapshot of all the volumes created on the cluster."
"HP EVA and once NetApp, but they both had slow performance and a lack of features so we switched."
"There were scalability issues, the scalability options are limited due to supported SSD."
"VNX can improve by offering flexible upgrade options. It's not possible to add a single HDD to a current array and there are fixed rules to make upgrades."
"Based on our workloads, we see repeatedly in performance reports that the built-in controller (SP) cache of our VNX model is not sufficiently large, resulting in forced cache flushing."
"So far we haven't had many issues with the VNX. However, the Data Mover (that manages CIFS/NFS) part needs some improvements."
"The administrative console (Navisphere/Unisphere) needs some improvement, especially on their Java-based GUI. The updated version of Java is not compatible."
"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."
 

Pricing and Cost Advice

"With VMware, we pay $300,000 annually."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"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."
"As far as the licensing costs, everything is included in the license."
"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."
"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."
"The support cost per array is about $20,000 a year for 24/7 support."
"All the licenses are included from day one of your purchase of the product, so you don't have to buy licenses separately. There are no additional costs to be paid for the maintenance of the solution."
"Compression is making a difference towards the amount of hardware that we need to 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."
"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."
"Pricing for this product is manageable, though slightly higher than comparable products."
"The price is up a little bit from what we used to pay so I'm hoping that it's a little bit of a better system than the VNXe was. But I still think it's a good value. It's new, so I'm sure there's room for the pricing to drop."
"The price in our country is very expensive and some of our customers opt for lower-cost alternatives."
"We checked both HP and Dell and we determined that Dell EMC was a better option."
"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.​"
"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. 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."

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.
