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 solution is scalable."
"The most valuable feature of this solution is reliability."

"Dell Unity XT is quite scalable and can be scaled up to the petabyte level."
"The Snapshot feature is key."
"Dell excels in service and support."
"Integration; We use the product with VMware, and also use it with Syft for home directory and departmental shares."
"The most valuable feature is that the solution is a hybrid system, so you can do both block and file storage."
"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."
"I like that when you log in it gives you a dashboard of what your storage looks like."
"Lenovo ThinkSystem DE Series is highly reliable, especially for block-level storage. It is stable, with minimal downtime and no issues beyond user errors."
"We have been working with the solution for around a year and so far it has shown itself to be stable."
"ThinkSystem's storage performs well, and the price per gigabyte is good, especially on SSD solutions. It's also easy to use."
"The solution's initial setup process is easy."
"Lenovo ThinkSystem DE Series is simple to use"
"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."
"This solution is good for virtualization and meets the need for CPU and RAM requirements."
"The solution is very easy to set up."
 

Cons

"I'd like to see the product implement active replication for vehicles such as VMware."
"The tool's pricing is higher than competitors."
"There is room for improvement in the pricing of the product."
"They could add more support for file storage and different types of storage."
"In terms of what needs improvement, the dashboard and management could be simplified."
"In the future, I would like to see integration with enterprise backup systems."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"The price of this product can be more cost-effective."
"Include cloud-based replication for blocks"
"This product needs to have better integration with enterprise backup solutions and archiving devices."
"In terms of what could be improved, I would say its capacity and its connection."
"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 the UI to look better."
"It is missing some features, like deduplication."
"There are some features in VNX that I wish were in the Unity. For example, Storage Groups for isolating LANs and hosts. That is a big issue."
"Improvements can be made to the product's performance."
"It would be useful to have structured solutions replicated to other sites."
"The features are limited."
"The solution could be more scalable, although it suits our present needs."
"ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec."
"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 type of connection that is used in Lenovo ThinkSystem DE Series should be improved."
 

Pricing and Cost Advice

"As far as the licensing costs, everything is included in the license."
"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."
"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."
"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."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"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."
"It's an expensive solution, particularly for medium companies. One device costs about 30,000 euros. The support contract is quite expensive as well. We are currently looking for other lower-cost solutions."
"Its biggest valuable feature is its price point for the amount of storage and performance you get. It's a sweet spot. It's cheaper than the other SANs out there, but performs well enough. It fits that nice, middle-ground portfolio."
"It is shipped with all licensed, included for this product range, no need to buy additional licenses"
"Our big return of investment is the ability to scale and not add FTE counts nor extra administration."
"Obtaining a warranty is easy."
"One of the most valuable features is its cost. It was inexpensive compared to other arrays that we were looking at."
"The price is good for commercial grade storage arrays."
"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."
"For an all-flash setup, the cost is around $20,000 for a decent configuration."
"The pricing is fair and low compared to other products in this category."
"All of the features are bundled together, and you can renew the bundle with all of the features included."
"We have a five-year contract for providing support."
"The best thing about this solution is its price, which reduces our costs."
"The pricing for this solution is good compared to HP or Dell EMC."
"The solution's price could be better."
"It is an expensive solution."
