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

"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"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 offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."
"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"It has benefited my organization because it has reduced time to insights."
"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."
"The database workloads are pretty fast because I frequently move data from here to there."
"The most valuable features of this solution are its ease of use and performance."
"The initial setup is very easy. I would rate my experience with the initial setup a nine out of ten, with one being difficult and ten being easy."
"One of the things that I like the most about it is how they have changed the Unisphere GUI, and how it is now HTML5. It is so easy to use. Also, the array itself is so simple, easy to set up and easy to use, but it still has that great Dell EMC technology behind it."
"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."
"We particularly like the user interface on cloud IQ with this product."
"Scheduled components are sourced from Korea based on their quality selection, with the actual purchase taking place in Vietnam. The notable features include cache memories and MOS feeder in Dell Unity. Additionally, the storage dynamics are managed uniformly on a global scale, whether it is a simple or wide-ranging configuration."
"It's easy to handle for administrators and it's a unified system. It's not as complex as Celerra systems or CX4 Clariions to administrate. You can do everything with one GUI."
"The most valuable features are its performance and simplicity."
"Unified block and file storage without the need of control stations and data movers. This simplifies administration and deployment and requires less rack space."
"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."
"Multi-tiering, positively affects the efficiency of the storage space."
"It is very stable, even during multiple power failures."
"The most valuable feature is the auto-tiering, which helps in the speed of data access."
"The most valuable feature is the tight VMware integration, due to the migration from bare metal to virtualized environments and then on to the cloud."
"High availability including non-disruptive updates: We cannot afford downtime windows."
"The replication feature provides another functionality to protect your data."
"The implementation of both block and file system storage in a single GUI provides is better situated than most other storages."
 

Cons

"The UI for this solution needs to be improved."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"We need better data deduplication."
"Adding some functions to the product would be beneficial."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"It is on the expensive side."
"This solution could be improved by offering containerization. This is something many of my customers are looking for."
"We've got massive issues at the moment with IBM AIX. It's not stable. We have a lot of disk errors, production crashes sometimes."
"The solution can use improvement with the patch cluster like the Synchron and Active replication."
"Currently, the protocol SNMP is not implemented. That's a problem, as we follow this protocol and I can't check the integrity of this equipment."
"More integration with VMware would always be helpful, plugins that go directly into the vSphere management. A single pane of glass is always beneficial."
"One area of improvement is replication. We are also using Oracle virtual machines, and when you are using systems from other vendors, the process of replicating from Unity through OLVM is more laborious than when we were using VPLEX."
"Data replication needs improvement as the future roadmap for RecoverPoint appliance is not there."
"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."
"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."
"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."
"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."
"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."
"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."
"The administrative console (Navisphere/Unisphere) needs some improvement, especially on their Java-based GUI. The updated version of Java is not compatible."
"Poor connection to FC."
 

Pricing and Cost Advice

"We pay approximately $50,000 USD per year in licensing fees."
"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."
"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 support cost per array is about $20,000 a year for 24/7 support."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"The product is expensive."
"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 license is not required, but we must renew the support every year, every two years."
"The pricing of Dell Unity XT is good."
"The product’s pricing should be improved."
"Obtaining a warranty is easy."
"It was easy to order. We are a big Dell shop, so it was easy to purchase and get it in place, then up and running."
"The support you're getting with it is probably an underestimated value that comes with the box you're buying."
"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."
"The solution is very expensive."
"Pricing is somewhat higher, especially in Zambia, perhaps due to the low sales volume."
"​Reducing dependency on JavaServer Pages​ (JSP) could improve the administrative overhead.​"
"The initial pricing and licensing are reasonable, the yearly EMC is more expensive"
"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."
"Over time, VNX has become pricier than its competitors, and we have turned enthusiastically to Unity."
"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 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.
