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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"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 solution is scalable."
"The most valuable feature of this solution is reliability."
"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."
"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."
"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"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 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."
"To be programmatically administered is huge, it is one of the key features that we like about it."
"It's easy to use, easy to manage, easy to troubleshoot, and the process support is good."
"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 scalability is really good now that they have the Dynamic Pools. We don't always have the money to buy complete write sets when we have to expand the storage, so now with the Dynamic Pools we can add disks on the go."
"It is easy to manage. A lot of the system manages itself."
"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."
"Dell Unity XT offers data integration features."
"Unity's are more easily administrated, so we need fewer people to do the administration. We have less overhead because of that."
"Lenovo ThinkSystem DE Series is simple to use"
"ThinkSystem's storage performs well, and the price per gigabyte is good, especially on SSD solutions. It's also easy to use."
"Its initial setup process is easy."
"I would rate the stability of Lenovo ThinkSystem DE Series as a ten."
"The solution is very easy to set up."
"The solution is very easy to troubleshoot. It's one of the most valuable features. It also doesn't take long to deploy and normally it comes with a three-year warranty."
"The solution's initial setup process is easy."
"This solution is good for virtualization and meets the need for CPU and RAM requirements."
 

Cons

"We've seen that when we create a POD in synchronous mode, it increases the latency."
"There is room for improvement in the pricing of the product."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"The software layer has to improve."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"In the future, I would like to see integration with enterprise backup systems."
"Maybe the price can be reduced since the solution is very expensive."
"It is on the expensive side."
"It needs deduplication. We'd like to have the dedupe capabilities in the Unity."
"The interface and configuration could improve."
"We have only used this solution for less than one year so I don't have any improvements suggestions yet."
"It could always use native replication. Then I could get rid of RecoverPoint."
"It could be a little easier to attach it to a network file system."
"Scalability for the 650F is good, but I was expecting a little bit more."
"In the dashboard there could be notification of duplicate files and the like, so we don't have to rely on Windows to do that."
"Dell EMC Unity is not sexy. It doesn't have all the flash and pizzazz of some of the other storage vendors."
"In the next release, I would like to see more functionality. But, again, it is an entry-level product."
"The difficult part comes when dealing with the host. You have to enable multi-pathing and other aspects that are needed for proper configuration. I don't know if there is room for a more hyper-conversion structure to work with, but this would be easier."
"The type of connection that is used in Lenovo ThinkSystem DE Series should be improved."
"Its performance could be faster."
"Usually, when a part fails, we have to replace it and it takes a while. It would be better if the part could be available locally here in Kenya so we don't have to wait so long to repair the solution."
"The product could support advanced software integrations."
"In the next release, I would like to see support for Hyper-converged infrastructure."
"There could be a snapshot feature in the solution."
 

Pricing and Cost Advice

"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."
"The support cost per array is about $20,000 a year for 24/7 support."
"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."
"Our licensing fees are $500,000+ USD."
"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."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"The product is expensive."
"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 price is very reasonable."
"Our big return of investment is the ability to scale and not add FTE counts nor extra administration."
"The price is good for commercial grade storage arrays."
"There is no capacity license for XT and no additional costs for expansions. I would rate its pricing as four out of five."
"What they really like is the easy licensing now - Dell EMC has caught up to a lot of their competitors - based on not having to charge for everything, and they can get everything in one bundle."
"Go with the virtual appliance versus the hardware."
"The solution is extremely functional for the price that we pay for it. It is worth the investment."
"In the SQL Server instances in our data warehouse, we immediately saw a great return on investment."
"For an all-flash setup, the cost is around $20,000 for a decent configuration."
"We have a five-year contract for providing support."
"It is an expensive solution."
"The pricing for this solution is good compared to HP or Dell EMC."
"The pricing is fair and low compared to other products in this category."
"The price of the Lenovo ThinkSystem DE Series is a one-time purchase. There is a global price list available to find the price of the solution."
"All of the features are bundled together, and you can renew the bundle with all of the features included."
"The best thing about this solution is its price, which reduces our costs."
