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

"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."

"I appreciate the performance."

"Overall stability is very good. It is a very stable solution."

"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."

"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."

"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 most valuable features of Pure FlashArray X NVMe are its superior performance compared to other flash tiers, as well as its ease of use, with an intuitive user interface that is simple to deploy and use."

"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."

More Pure FlashArray X NVMe pros

"Dell PowerMax NVMe has been a significant enhancement for data handling in my industry. Its improved security features and data calculation capabilities make it a valuable solution for our customers. The most critical feature of Dell PowerMax NVMe for performance enhancement is its strong network support and integration with other vendors, along with its efficient use of hardware components like CPU and memory.

Cons

"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."

"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."

"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."

"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."

"I would like to see some AI features that would allow arrays to intelligently identify threats or unusual behavior in the data pattern and give an alert."

"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."

"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."

"The UI for this solution needs to be improved."

More Pure FlashArray X NVMe cons

"There are areas for improvement in AI, interface, support, and customizations."

"I would also like to see a real-time, graphical view of metrics. I don't know how far back in time we can look, but if we could see the performance from two months or three months back, and how it is performing now, that would be helpful."

"If the solution had more power-saving capabilities, it would be quite nice."

"The initial setup process is difficult."

"We are very interested in NVMe over Fibre Channel, which I understand is on the horizon. We would like to see that come to fruition."

"There are some stability issues that we just recently experienced. We hope the next release will solve these problems."

"The initial setup was complex, as it is a complex system and you have to learn a lot."

"The one area for improvement in Dell PowerMax NVMe would be to align the features of the on-premises version with those available in the cloud, as this would provide added value and flexibility."

More Dell PowerMax cons

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

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

Pricing and Cost Advice

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

"The licensing is on a yearly basis."

"We pay approximately $50,000 USD per year in licensing fees."

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

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

"Given its price, Pure is not the first option."

"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."

"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."
