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.

Has a fantastic feature-set and works well with workflow solutions
I would suggest, if you heavily depend on the Oracle solution from the database you should consider Oracle All-Flash because, from my understanding, it is from a single OEM, it's a single solution. It would be a homogeneous environment. I think it would be definitely a better option for customers considering other all-flash storages. It would be better if you consider a solution from Oracle, from the database studio, the storage part. I would rate it an eight out of ten. To make it a perfect ten, in the next release, I would like for it to be NVMe compliant storage.

Quotes from Members

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

Pros

"The solution uses newer technology for deduplication and compression."
"The solution is scalable."
"One of the best features is the support, which is excellent."
"The tool's valuable features are speed, security, data compression, and reliability. Its data compression feature is the best that we have ever seen. It helps us to save money and resources."
"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 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."
"It is easy to scale, maintain, and manage."
"Its most valuable feature is the storage alarm."
"The most valuable feature is the fast cache with functionality rewrite."
"Compared to older generations of arrays there is quite an improvement, compared to the older VNXs, for example. It depends on you use it, but for our purposes, we find Unity simple to use."
"It has improved the utilization of our own internal resources and performance across our managed service platform, meeting our customers SLAs."
"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."
"Unity's are more easily administrated, so we need fewer people to do the administration. We have less overhead because of that."
"Setup is simple."
"It's actually shaking hands with the workflow solutions much better than any other storage."
 

Cons

"We've seen that when we create a POD in synchronous mode, it increases the latency."
"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."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"One point I'd like to improve is that the tool should start selling small boxes again. It discontinued some products and is focusing on bigger, more capable boxes, neglecting the SMB market. Even though it's not a big market, it shouldn't have removed them."
"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"The tool's pricing is higher than competitors."
"This solution would be improved with the addition of flexible raid volumes."
"The monitoring part could be better. With EMC storage systems - or Unity and VPLEX, because I'm using them, for the moment - the monitoring part is very difficult. They should improve this to have a better reporting system."
"We noticed in the last release of code that there were some inefficiencies around getting our data efficiency up in terms of dedupe and compression."
"One of the issues we've had is that controllers have crashed several times... We've had a lot of problems with the storage processor, SPBs. We've actually had them crash."
"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."
"Last (and I understand that it has a low chance of being implemented) the copy services currently are redirect on write. It would be great if the administrator could choose between redirect on write and copy on write, when configuring copy job."
"The user interface could be improved. The Dell Compellent user interface is fantastic, but the Unity user interface is, in comparison, pretty lousy. It's functional, and I can do what I need, but the Dell Compellent user interface is so much more intuitive and user-friendly."
"There is an issue with data duplication occurring on the flash memory. It should be improved. Timely updates and upgrades to the latest versions would be great."
"It has to be flexible according to the customer's requirements. It has to be aligned with the customer business and the business environment."
 

Pricing and Cost Advice

"With VMware, we pay $300,000 annually."
"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."
"As far as the licensing costs, everything is included in the license."
"The support cost per array is about $20,000 a year for 24/7 support."
"Given its price, Pure is not the first option."
"We pay approximately $50,000 USD per year in licensing fees."
"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 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."
"Our big return of investment is the ability to scale and not add FTE counts nor extra administration."
"All the licenses are included from day one of your purchase of the product, so you don't have to buy licenses separately. There are no additional costs to be paid for the maintenance of the solution."
"The solution is very expensive."
"The solution should be cheaper."
"The return on the investment was simply speeding up our entire vSphere stack, which allowed our developers and engineers to get their workloads done faster and simpler. We were experiencing VM snapshot times of 45 minutes to two or three hours, and it shrunk it down to under five minutes."
"This product is cheaper than the EMC VNX solution. It is good for small businesses."
"It is a good return on investment."
