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

"It has good, reliable, fast storage."
"The most valuable features of this solution are its ease of use and performance."
"The solution uses newer technology for deduplication and compression."
"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."
"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."
"It's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."
"It is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."
"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"I like the easy management with the new Unisphere management and the HTML5 interface."
"It is great because it can work as a SAN and net storage."
"The fact that it's hybrid is the most valuable feature. We have the SSD so we put our SharePoint on there and some of the stuff that requires a little more speed. For SharePoint, we want the pages to respond a little more quickly. And it's nice to be able to use the slower storage for stuff that we don't need as quickly, like file servers."
"It is simple to use and easy to manage. We don't touch it after we set it up."
"They have a Unity REST API that I use to automate some of the storage stuff. I'm just getting started with it, but it seems pretty easy to use."
"We're able to access it from just about anywhere, as long as we have access to a browser. That feature is really neat because sometimes we will go to a different data center or a different site, and if we need to access it to see a LUN or to see any type of storage, we can do that. That's one of the big takeaways with Unity."
"Provides good provisioning, allowing us to save space."
"The product has helpful local technical support."
"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."
"The replication feature provides another functionality to protect your data."
"FAST (auto-tiering): Doesn't require configuration and is managed by the array itself."
"Integration with VMware"
"The implementation of both block and file system storage in a single GUI provides is better situated than most other storages."
"I really value deduplication and compression to save space."
"Good performance for VM environments"
"High availability including non-disruptive updates: We cannot afford downtime windows."
 

Cons

"In the future, I would like to see integration with enterprise backup systems."
"Adding some functions to the product would be beneficial."
"I'd like to see the product implement active replication for vehicles such as VMware."
"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."
"We need better data deduplication."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"The tool's pricing is higher than competitors."
"Maybe the price can be reduced since the solution is very expensive."
"We did encounter a firmware bug which actually caused loss of data. There was some heartburn around that. But in general, it has operated as expected, except for that bug."
"They can certainly improve in terms of monitoring."
"We would like to see more advanced integration capability added to this solution."
"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. I don't know which replication job is actually feeding it. I have to go in and rely on other apps."
"We do a lot of VMware. It only integrates with VMware in one way, which is virtual volumes. I don't really have any visibility on anything else. From VMware, I can't look into Unity. From Unity, I can't look into VMware unless I am using virtual volumes, where they integrate together happily, but we are not using that. I would like better integration for non-virtual volume VMware use."
"There is an issue with data duplication occurring on the flash memory. It should be improved. Timely updates and upgrades to the latest versions would be great."
"The technical support sometimes takes three to four days to get hardware to facilities. I would rate customer service four out of ten."
"This product lacks deduplication and compression at the current version 4.1.0. LACP is not available for iSCSI either."
"Poor connection to FC."
"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."
"The CLI could be better documented, like with VMAX."
"EMC VNX needs to support bigger SSDs. Next generation EMC Unity will do this."
"Intel Xeon processors with under 2 GHz processing speeds could be replaced with more recent ones."
"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."
"The administrative console (Navisphere/Unisphere) needs some improvement, especially on their Java-based GUI. The updated version of Java is not compatible."
"The scalability is average because the storage has some hardware limitations and, obviously, operating system limitations."
 

Pricing and Cost Advice

"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."
"The product is expensive."
"We pay approximately $50,000 USD per year in licensing fees."
"With VMware, we pay $300,000 annually."
"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."
"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."
"We integrated it with VMware vSphere at no additional cost. As we moved into VMware vSphere, this is what we bought to go with it for our storage performance."
"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."
"This unit is one of the cheapest storage all-flash arrays in the market and it does well for what it is intended. It can be combined for both file and block storage."
"We purchased a five-year warranty."
"Most licenses for the solution are free but upgrades are available when adding additional software or storage."
"Our big return of investment is the ability to scale and not add FTE counts nor extra administration."
"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."
"From an ROI perspective, I'll put it this way: When we've tried to buy other SANs, the Unity ROI makes it impossible to buy them. So usually, the only time we buy another SAN is when the ROI isn't a factor, because Unity can't do the job. From an ROI perspective, it's great because it beats everything else out. We've tried to look at other options but, at the end of the day, when you price it out, the Unity wins."
"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.​"
"The initial pricing and licensing are reasonable, the yearly EMC is more expensive"
"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."
"Over time, VNX has become pricier than its competitors, and we have turned enthusiastically to Unity."
"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.
