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.

I use Lenovo ThinkSystem DE Series to replace the old storage in our infrastructure. Additionally, I use it in customer infrastructures to migrate from the old storage to the new one On the M storage, I find the best features to be deduplication and compression. On the DE storage, the most…

Quotes from Members

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

Pros

"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"Technical support has been helpful and responsive."
"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"The database workloads are pretty fast because I frequently move data from here to there."
"I appreciate the performance."
"FlashArray has some fresh efficiency features. I've never seen a storage solution with a compression rating this high before. It's at least 4-to-1 on Oracle databases. It's the best flash storage for Oracle."
"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 latency is good."
"It is simple to use and easy to manage. We don't touch it after we set it up."
"The storage management is superb, with a user-friendly graphical interface and dashboards. The performance is good. The integration, dashboards, and analytics are excellent. It gives me immediate output and quick access to the reports I need promptly. It's an excellent product with high stability. The solution is scalable. The support team is highly supportive, responsive, and efficient in providing solutions. This product is highly useful and well-suited for all types of automation."
"It is very user-friendly to read and determine the exact problem, unlike HP where different tools and L3 team support are needed."
"Compared to our old platform, everything is more tightly integrated. I don't have to go to different sections to do something. A lot of it is wizard-driven, so it's an easy to use system."
"Snapshots provide a unique feature for testing and make management more comfortable and easy."
"We have resolved IT challenges with this solution. It sped up our environment. We went from spinning disk to all-flash, which reduced our footprint."
"Via a click, we can deploy a data store or LUN to the ESX host. We can also deploy VVOLs to the ESX server."
"Ease of use is probably number one, compared to the previous storage that we've had. Easy scalability, easy set up. Compared to everything else, the Unity is, well, you could call it child's play. As long as you know what you're doing storage-wise, Unity is really easy to use."
"Lenovo ThinkSystem DE Series is highly reliable, especially for block-level storage. It is stable, with minimal downtime and no issues beyond user errors."
"The solution is very easy to set up."
"We have been working with the solution for around a year and so far it has shown itself to be stable."
"The solution's initial setup process is easy."
"ThinkSystem's storage performs well, and the price per gigabyte is good, especially on SSD solutions. It's also easy to use."
"This solution is good for virtualization and meets the need for CPU and RAM requirements."
"Lenovo ThinkSystem DE Series is simple to use"
"Fewer features is not necessarily a negative as it leads to simpler operation and lower price."
 

Cons

"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."
"We need better data deduplication."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"In the future, I would like to see integration with enterprise backup systems."
"It feels more suitable for small and medium-sized businesses rather than enterprises."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"It could be improved in the area of management flexibility. For example, I really need to set read-only access for LUNs, and there's no such option with Unity XT."
"I would like better integration with RecoverPoint. My major issue with the solution, all around, has been RecoverPoint more than Unity. While I like the easy user interface, I would like some more advanced features for troubleshooting built into the product, so that we can do more in-depth problem-solving."
"Sometimes the response time is higher than expected due to a lack of issues."
"We've got an ongoing issue with a Unity where some power supply fans spin up. We've had a whole bunch of hardware changed as a result but I still have an open SR which has been a struggle. It doesn't seem to affect performance, but it's something that we're hoping the engineers can resolve. Also, we had some issues with an upgrade where we can't manage a device, after the upgrade. So we had to have a ticket in for that."
"VNX used to have some features that Unity still doesn't have. From that perspective, the progress is not that advanced."
"Scalability for the 650F is good, but I was expecting a little bit more."
"Having more artificial intelligence tools built into the solution would be a great benefit. This would allow us to see more about the workloads and higher visibility, such as performance degradation."
"I think that they could do a better job of testing on the back-end, for the code revisions. I've heard of some issues down the line where people have upgraded to the latest code and there were bugs in it, and they had to release a subsequent code fix."
"Its performance could be faster."
"The solution could be more scalable, although it suits our present needs."
"It would be useful to have structured solutions replicated to other sites."
"Improvements can be made to the product's performance."
"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."
"In the next release, I would like to see support for Hyper-converged infrastructure."
"ThinkSystem could be better integrated with backup software like Commvault, Veritas, or Symantec."
"The features are limited."
 

Pricing and Cost Advice

"As far as the licensing costs, everything is included in the license."
"Our licensing fees are $500,000+ USD."
"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."
"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."
"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 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."
"We pay approximately $50,000 USD per year in licensing fees."
"We have to apply for a license for each system."
"I rate Dell Unity XT’s pricing a nine out of ten."
"The Dell EMC Data Protection license covers everything, like a one stop shop. All our options are covered."
"The pricing is reasonable. We're using the Flex on Demand pricing. It's really good for us when we pay for what we use. It made it easy to get it inside since it's an OpEx and instead of CapEx expense."
"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."
"Go with the virtual appliance versus the hardware."
"For costing, you have to have a budget in mind because SANs can be fairly expensive and EMC offers a wide range of products."
"Pricing for this product is manageable, though slightly higher than comparable products."
"The pricing is fair and low compared to other products in this category."
"It is an expensive solution."
"We have a five-year contract for providing support."
"The pricing for this solution is good compared to HP or Dell EMC."
"The solution's price could be better."
"For an all-flash setup, the cost is around $20,000 for a decent configuration."
"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."
