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

"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."
"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."
"The solution uses newer technology for deduplication and compression."
"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"The high availability of the product is the most valuable feature."
"We are satisfied with the performance as it is significantly faster compared to traditional storage options."
"The most valuable feature of this solution is reliability."
"Everything, especially the VMs inside, is pretty fast."
"It is lightning fast, low on power and heat, and has a small footprint with great performance."
"It is easy to manage. A lot of the system manages itself."
"The setup and installation procedures are easy."
"The most valuable feature is the integration with vCenter."
"The most valuable feature is the fast cache with functionality rewrite."
"The initial setup was very straightforward. Migration was smooth and configuration of the storage was quick and simple. The time needed to put it into production was less than expected, and data migration itself went without a glitch."
"A lot of the Unisphere interfaces are greatly improved in terms of monitoring capabilities, alerting, and ease of use. Setting up the storage and the file system are all just a few clicks away."
"I like that the performance is very good."
"Its initial setup process is easy."
"This solution is good for virtualization and meets the need for CPU and RAM requirements."
"The solution's initial setup process is easy."
"We have been working with the solution for around a year and so far it has shown itself to be stable."
"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."
"Lenovo ThinkSystem DE Series is quite an elementary box, no frills. It does not have all the functionality of the DM but it is acceptable, it does its task. It integrates pretty well."
"The most valuable features of the Lenovo ThinkSystem DE Series are the dual controllers, available installation documentation, and the option of multiple host bus adapter interfaces."
"The solution is very easy to set up."
 

Cons

"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"Adding some functions to the product would be beneficial."
"The tool's portfolio is minimal. It is expensive."
"Maybe the price can be reduced since the solution is very expensive."
"It feels more suitable for small and medium-sized businesses rather than enterprises."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"The UI for this solution needs to be improved."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"Stability is the problem. We've had stability issues with it. We've had problems with the iSCSI interface. We've had it for two years now and for two years we've had problems where a service processor will drop, we'll lose connectivity to LUNs, we'll lose connectivity to the storage, issues like that. No matter how we've tried to chase it down, everybody just points fingers at each other. The only thing that changed in our environment was that the Unity solution was installed."
"Support Responsiveness & time to fix bugs should be improved."
"Dell could improve Unity XT by adding support for NVMe."
"Dell EMC's competitor has a clustering technology. In the next release, it would be nice if they could build that into the product."
"I would like to see them add Storage Groups, like we have had in Clariions and VNXs."
"It needs deduplication. We'd like to have the dedupe capabilities in the Unity."
"On the data domains - for the Unity product, but specifically for data domain - I would like a much easier interface for managing, for actually going in and having one place where I could get all of the different parts of the overall unit. And I would also like to be able to identify individual disks a lot more easily."
"I would like to see more integration with other products."
"Its performance could be faster."
"The type of connection that is used in Lenovo ThinkSystem DE Series should be improved."
"The solution could be more scalable, although it suits our present needs."
"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."
"There could be a snapshot feature in the solution."
"The product could support advanced software integrations."
"ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec."
"It would be useful to have structured solutions replicated to other sites."
 

Pricing and Cost Advice

"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"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."
"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."
"Given its price, Pure is not the first option."
"As far as the licensing costs, everything is included in the license."
"With VMware, we pay $300,000 annually."
"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."
"It's the performance combined with the gig-per-dollar value. That combination is superior to other storage options."
"There is not a license required for the use of the solution. We purchased a maintenance contract."
"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 pricing was quite okay compared to others. We probably got it cheaper because we were the first ones out of the gate, but I would say that it's good value for the money."
"Go with the virtual appliance versus the hardware."
"We purchased a five-year warranty."
"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."
"Just from an overall power and heating usage, it costs substantially less than some of our existing solutions"
"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."
"The pricing is fair and low compared to other products in this category."
"We have a five-year contract for providing support."
"The pricing for this solution is good compared to HP or Dell EMC."
"It is an expensive solution."
"The solution's price could be better."
"For an all-flash setup, the cost is around $20,000 for a decent configuration."
"The best thing about this solution is its price, which reduces our costs."
