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

"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."
"We generally always advise people to make the choice to go with Pure Storage because they won't regret it."
"Technical support has been helpful and responsive."
"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."
"It has benefited my organization because it has reduced time to insights."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"The database workloads are pretty fast because I frequently move data from here to there."
"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."
"Unified block and file storage without the need of control stations and data movers. This simplifies administration and deployment and requires less rack space."
"The most valuable feature is the fast cache with functionality rewrite."
"All-flash array eliminates all the overhead of tiering and a lot of the data structuring overhead involved."
"The inline deduplication and data reduction capabilities have been the most valuable."
"Before the product went in, we did not have any centralized storage, and now it is a single source of knowledge and repository for all our data, making our lives a lot easier and improving our disaster recovery because we have two of them in place replicating."
"We use replication for disaster recovery (DR), making our DR process much easier."
"The most valuable feature of Dell Unity XT is data duplication. Additionally, the management interface is simple, and is not a hassle using it. You don't need too much to learn or to be familiarized with it."
"It has good performance."
"I really value deduplication and compression to save space."
"Tiering, because it allows your data to dynamically move among different disk types based on demand in the last 24 hours."
"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."
"FAST (auto-tiering): Doesn't require configuration and is managed by the array itself."
"In a banking environment, on which we required a very high throughput for our database, we have used this product and our desired response was received."
"Reliability, excellent support by EMC, and VMware integration High availability including non-disruptive updates: We cannot afford downtime windows."
"The replicating of the entire storage unit to a different location was a very useful function."
"Customer service is top-notch with a dedicated sales and technical resource who are familiar with your environment and spend a lot of time understanding your business needs."
 

Cons

"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."
"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."
"They could add more support for file storage and different types of storage."
"The tool's portfolio is minimal. It is expensive."
"One area that I haven't been sold on yet is the POD replication."
"The software layer has to improve."
"In the future, I would like to see integration with enterprise backup systems."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"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."
"They should update to the cloud."
"We've got an ongoing issue with a Unity where some power supply fans spin up. We've had a whole bunch of hardware changed as a result but I still have an open SR which has been a struggle. It doesn't seem to affect performance, but it's something that we're hoping the engineers can resolve. Also, we had some issues with an upgrade where we can't manage a device, after the upgrade. So we had to have a ticket in for that."
"Dell EMC Unity's competitor, NetApp, has a similar product. However, it has a clustering technology where you can group multiple systems together, then you can move data from one system to another seamlessly. I would like the Unity to do that."
"In future releases, I would like to see automatic upgrades from one to the next, when this system is coming out and the next one is coming in; more akin to what Pure Storage is doing. That would be really helpful."
"The VNX reporting is much more granular, versus the Unity reporting."
"In terms of what could be improved, I would say its capacity and its connection."
"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."
"Poor connection to FC."
"I do not recommend the Gen 1 VNX to anyone in this day and age."
"There is an easy replication process between distinct data centers via VPLEX and/or RPA. But I hope in the future that EMC/Dell could replicate this with other types of storage."
"I think one area where we would like to see improvement is better deduplication and compression."
"It would be very helpful to get an automated report that shows you the size of the checkpoints and get warnings when a checkpoint is reaching either maximum capacity per a file system or hitting the ceiling on the SavVol pool consumption."
"There were scalability issues, the scalability options are limited due to supported SSD."
"HP EVA and once NetApp, but they both had slow performance and a lack of features so we switched."
"Intel Xeon processors with under 2 GHz processing speeds could be replaced with more recent ones."
 

Pricing and Cost Advice

"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"Given its price, Pure is not the first option."
"The support cost per array is about $20,000 a year for 24/7 support."
"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."
"We pay approximately $50,000 USD per year in licensing fees."
"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."
"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."
"The licensing is on a yearly basis."
"The pricing of Dell Unity XT is good."
"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."
"Licensing is easy since all the software is included."
"There is an annual charge for the license of this product. It has better pricing than its competitor: Pure Storage."
"We looked at HPE Nimble but the price of the Unity XT was very good compared to the competition."
"The price of Dell Unity XT is reasonable. However, if you are buying a custom solution, it can come at a considerable price."
"The Dell EMC Data Protection license covers everything, like a one stop shop. All our options are covered."
"The pricing is reasonable. We're using the Flex on Demand pricing. It's really good for us when we pay for what we use. It made it easy to get it inside since it's an OpEx and instead of CapEx expense."
"Over time, VNX has become pricier than its competitors, and we have turned enthusiastically to Unity."
"​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."
"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."
"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"

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.
