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.

High‑performance all‑flash storage has transformed data warehousing and reporting speed

The features of Dell PowerMax that I find most valuable so far include its all-flash capability, along with its performance, reliability, and efficiency. Additionally, it has snapshot-level features that allow me to take snapshots or backups within only a few seconds. There is no need to wait long, and unnecessary high bandwidth used for backup does not occur because I can take the whole snapshot backup within a fraction of a second. I have used the deduplication feature of Dell PowerMax. Deduplication and compression are very effective, so despite my large amount of data, the effective size is reduced due to this deduplication and compression, allowing me to store more data on the same storage. Regarding the impact of Dell PowerMax's real-time data encryption on my data protection strategies, I have not used that feature personally. However, in another department, my colleagues are using it, and they have not faced any performance bottlenecks due to data encryption. The encryption is very powerful, but I have not implemented that encryption in our database data warehouse systems since they are for internal use only, not exposed worldwide. At first, I faced several issues, and our report rendering complaints were quite annoying. However, now with Dell PowerMax storage's high IOPS handling capabilities, the output comes within a fraction of a second, making our users happy. Whatever our requirement or demand is, it has already been implemented in Dell PowerMax with its all-flash NVMe storage. New bricks can also be added if a size increase is required, allowing for additional bricks to be added as needed. Everything is in place; therefore, I do not think any other improvements are required. However, it is worth noting that Dell is continuously inventing and releasing more powerful types of storage. This results in increased reliability, enhanced data handling capabilities, improved deduplication ratios, and the fulfillment of more IOPS demand.

Stability-wise, a device that has been up and running for years

The failover capability and resiliency are some of the solution's valuable features. The big thing is resilience because it has richer coding in it, so multiple devices can't fail. Also, one can still access a number of CBoxes that can allow one to access their file system. Once a device fails, it fails the transparency of the end-user, and it just starts using another resource. The encryption capability, the snapshots, along with a whole bunch of features make the tool valuable. VAST Data keeps adding more and more features all the time.

Quotes from Members

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

Pros

"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."

"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."

"The initial setup was extremely simple and straightforward."

"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."

"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."

"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."

"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."

"What we've seen on the Xs, and the Pures in general, is that we can scale way beyond what we need to without any degradation in performance."

More Everpure FlashArray X NVMe pros

"We have worked with customer success support, and the service is very good."

"The solution's technical support was good, and it is one of the tool's main advantages."

"It has dramatically cut down the footprint in our data center and reduced the amount of raw disk capacity that we needed to purchase."

"The solution is stable. I would rate it ten out of ten."

"The compression and deduplication are the most valuable features because of the cost savings."

"The features of Dell PowerMax that I find most valuable so far include its all-flash capability, along with its performance, reliability, and efficiency."

"As a major service provider, who has been working with Dell EMC for well over a decade, hosting mission-critical applications for important brands and businesses, along with some health institutions, where access to data is literally a life or death, we have to go with a system that we can trust without fail, and PowerMax has been giving that to us."

"The most valuable feature of Dell PowerMax NVMe is its replication feature."

More Dell PowerMax pros

"This has been one of the most reliable storage systems that I have ever used."

"The solution is useful for machine learning and scientific applications, including computer simulations."

Cons

"I'd like to see the product implement active replication for vehicles such as VMware."

"It feels more suitable for small and medium-sized businesses rather than enterprises."

"We've seen that when we create a POD in synchronous mode, it increases the latency."

"The tool's portfolio is minimal. It is expensive."

"Adding some functions to the product would be beneficial."

"In the next release, I would like to see real-time analytics for further insight into consumption models."

"There is room for improvement in the pricing of the product."

"In the next release, I would like to see real-time analytics for further insight into consumption models."

More Everpure FlashArray X NVMe cons

"They should work with the storage engineers to better tweak the management tools to give them improved visibility into their data."

"The price could be lower, and we are unhappy with the price."

"Dell can improve the Service Level Agreement (SLA) compliance. Sometimes, when we need to replace a component, the SLA says four hours, but for some reason, the technician doesn't arrive until the next business day or even six to eight hours later before the case is placed. So, focusing on respecting the SLA is where Dell could improve."

"Dell PowerMax or Symmetrix is a block-level storage and unified storage, supporting both NAS and SAN. One area for improvement would be integration with public cloud services."

"I would like to see the rack change. They have defaulted to the standard rack, so our fiber cables are crowded when we shut our back door."

"There is some room to grow, especially with some of the installation quirks."

"We would like more documentation, a guide to the features of the PowerMax."

"I would like to see more development in the cloud environment. It would be good if it comes in the cloud kind of setup."

More Dell PowerMax cons

"The read/write ratio is an area in the solution with some flaws and needs improvement."

"The write performance could be improved because it is less than half of the read performance."

Pricing and Cost Advice

"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."

"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."

"Our licensing fees are $500,000+ USD."

"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."

"With VMware, we pay $300,000 annually."

"The product is expensive."

"The support cost per array is about $20,000 a year for 24/7 support."

"Pure FlashArray X NVMe’s pricing is cheaper than other products."

More Everpure FlashArray X NVMe pricing and cost advice

"Its price is competitive, but they need to have a different price for West Africa. They can do better with the price point to allow us to scale even more. We wanted to migrate our entire storage infrastructure to PowerMax, which would require us to buy more capacity, and from the price point, it didn't attract us."

"One area for improvement, one that everybody always comes to, is price... it's still quite expensive to purchase these big arrays... For us, the pricing doesn't make Dell EMC uncompetitive."

"The cost is expensive. While VMAX now has good pricing, PowerMax is a little expensive."

"I think it is an expensive tool, but it is the best product. I think it is expensive and the cost one must pay for the best solution."

"The PowerMax appliance pricing was reasonable. Dell EMC quoted us a substantial discount."

"Since Dell PowerMax NVMe is an enterprise storage, its price is premium."

"The price is on the market. It's not inexpensive, but it's available on the market."

"We hope that with the combination of both NVMe and SCM the next PowerMax will be much cheaper that the one which we acquired."

More Dell PowerMax pricing and cost advice

"Price-wise, VAST Data is not the cheapest, not the most expensive one."

"We acquired VAST Data as a one-time, capital purchase."
