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.

Efficient data replication and fast IOPS have improved operational performance
Dell and a partner jointly implemented this solution in Auvink. We installed the Flash, which makes our IO operations fast and efficient. Replication is available, allowing us to replicate data simultaneously from one site to another. All-flash technology and vTXT enhance speed, and the IOPS are faster. The cache's IOPS are much better. Snapshots provide a unique feature for testing and make management more comfortable and easy. The platform is multi-supported and certification is more convenient and easy to manage.

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

"We're able to get higher-density workloads on the same infrastructure, and we have a smaller physical footprint. The performance is excellent – during our test the bottlenecks are never on the X array, it just keeps picking up the pace to match what you need. The real-time visibility is a differentiator in my opinion."
"It has good, reliable, fast storage."
"The solution uses newer technology for deduplication and compression."
"The latency is good."
"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."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"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 high availability of the product is the most valuable feature."
"There has been no downtime. It has built-in redundancy upon redundancy."
"For sites that we use it on, it gives us more flexibility and high availability solutions. It is easier to expand the site, if needed."
"I like that when you log in it gives you a dashboard of what your storage looks like."
"We've never had an issue with storage."
"Provides good provisioning, allowing us to save space."
"It has good performance."
"It's easy to use, easy to manage, easy to troubleshoot, and the process support is good."
"Setup is simple."
"The implementation of both block and file system storage in a single GUI provides is better situated than most other storages."
"FAST (auto-tiering): Doesn't require configuration and is managed by the array itself."
"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."
"Good performance for VM environments"
"The replication feature provides another functionality to protect your data."
"I really value deduplication and compression to save space."
"Multi-tiering, positively affects the efficiency of the storage space."
"Integration with VMware"
 

Cons

"Managing data isn't difficult for me. The performance is usually perfect, but we sometimes have capacity problems."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."
"There are some challenges with data encryption and reduction."
"I'd like to see the product implement active replication for vehicles such as VMware."
"One point I'd like to improve is that the tool should start selling small boxes again. It discontinued some products and is focusing on bigger, more capable boxes, neglecting the SMB market. Even though it's not a big market, it shouldn't have removed them."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"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."
"Compression and block deduplication on non-all-flash solutions."
"Replication with VMware - it's called the vSphere Metro Storage Cluster - is lacking in the Unity and is present in Compellent."
"A customer had to buy VMX because Unity didn't have WORM."
"The VNX reporting is much more granular, versus the Unity reporting."
"It is expensive, and the pricing could be better."
"The price of this product can be more cost-effective."
"I'd like to see more of the NVMe back-end for the flash. And the big deal with the PowerMax is that they've used all U2 drives so that they can avoid having to take it down. I see using M.2 and modular sections as being a real nice alternative that could be implemented in Unity at a fairly low cost."
"Because we can do synchronous replication between the two sites, this made the setup challenging for this piece. They did not know how to set this up initially. We ended up having to do bidirectional synchronous replication."
"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."
"Intel Xeon processors with under 2 GHz processing speeds could be replaced with more recent ones."
"If the VNX had embedded encryption, that would be great."
"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 scalability is average because the storage has some hardware limitations and, obviously, operating system limitations."
"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."
"The CLI could be better documented, like with VMAX."
"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."
 

Pricing and Cost Advice

"We pay approximately $50,000 USD per year in licensing fees."
"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."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"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."
"Our licensing fees are $500,000+ USD."
"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."
"Currently, we buy directly from Dell EMC. We've tried going through resellers before, but we've found that if we go directly through Dell EMC, we get a good a price from being with the government."
"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."
"Here is our major complaint with pricing. Dell EMC comes to us and gives us a price. We are like, "Well, this doesn't even compare to what we got on the last project." We say, "No, you should bring it down to this level." Then, they come back again and we are sort of in the middle again. I am like, You already sold us other stuff at a better price. We are not going to just say, 'Yes,' because we are out of time.""
"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."
"Obtaining a warranty is easy."
"This product is cheaper than the EMC VNX solution. It is good for small businesses."
"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."
"Pricing is as high as it has ever been for EMC."
"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 initial pricing and licensing are reasonable. Yearly EMC is more expensive."
"​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."
"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."

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.
