Chief Technology Officer at Lambda256

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.

Enhanced speed and integration benefit hybrid environments but cost remains a concern

The Hitachi VSP E Series is all-flash storage, so it is fast. It is quite good for databases, and clients who are familiar with Hitachi prefer to use it. Clients with hybrid environments generally look for something like a single glass view, where they can integrate all their different systems and view everything on one screen or desktop.

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 solution is scalable."

"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 solution is very straightforward to set up."

"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."

"The latency is good."

"One of the best features is the support, which is excellent."

"We are satisfied with the performance as it is significantly faster compared to traditional storage options."

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

More Pure FlashArray X NVMe pros

"Hitachi VSP handles large volumes of transactions with ease, and we often support customers in this direction when we have Oracle in the middle."

"The most valuable features of Hitachi VSP series include its high performance and availability."

"We are using the Hitachi VSP E Series for high IOPS."

"The product is generally quite stable."

"I rate Hitachi VSP series nine out of ten for a transactional workload requiring no compromise on availability and performance."

"Its user-friendly configuration and maintenance processes contribute to its reputation for being straightforward and easily manageable."

"It offers good file sharing."

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

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

Cons

"They could add more support for file storage and different types of storage."

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

"It is on the expensive side."

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

"We would like to see more visibility into garbage collection and CPU performance in the GUI."

"There are some challenges with data encryption and reduction."

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

"We would like to see VNC integration or be able to use Pure Storage with VNC."

More Pure FlashArray X NVMe cons

"The graphical user interface is somewhat outdated, lacking some of the modern features found in other solutions."

"There is room for improvement in simplifying the overall complexity of the environment."

"Hitachi should work on unified storage platforms."

"The solution's support duration or end-of-support life is very short."

"Hitachi should work on unified storage platforms."

"Hitachi is quite expensive, and small to medium-sized organizations usually do not purchase it."

"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

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

"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."

"As far as the licensing costs, everything is included in the license."

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

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

"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."

"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."

"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."

More Pure FlashArray X NVMe pricing and cost advice

"The pricing is fair, with additional costs for support services."

"Hitachi VSP E Series is an expensive solution."

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

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