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.

Resilience has supported proactive management and secured audit readiness across multiple sites

The resilience in Dell PowerStore benefits my company from an auditing perspective because we know we have that resilience in place. I see Dell PowerStore playing a bigger role in the future because we are starting to use it more, and that is pushing it. The biggest return on investment for me when using Dell PowerStore is scalability. Scalability is key. I can amplify that scalability is the biggest return on investment because we have redundancy between two sites; if something goes down, we have to manage it, but we want to do it proactively.

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."

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

"Everything, especially the VMs inside, is pretty fast."

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

"The initial setup was extremely simple and straightforward."

"The most valuable feature of this solution is reliability."

"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."

"On a scale of one to ten, I rate Pure FlashArray as ten."

More Pure FlashArray X NVMe pros

"The user interface is really simple to get behind and makes it really easy to expand and utilize the tools."

"Currently, the features of replication and deduplication have been very important to us."

"In my view, if a storage array requires constant monitoring or 'whispers in your ear' every five minutes with issues, it isn't doing its job. Because the sites currently running PowerStore are silent and stable, I consider the Return on Investment to be excellent. It provides exactly the peace of mind we are looking for."

"With Dell PowerStore, we have achieved twenty percent savings compared to the previous solution."

"The solution is very easy to implement."

"Deduplication and compression perform exceptionally well, especially on Dell PowerStore."

"The management portal is particularly user-friendly."

"Dell PowerStore is highly versatile and offers numerous features that can be tailored to specific customer needs."

More Dell PowerStore pros

"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

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

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

"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."

"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."

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

"In terms of what needs improvement, the dashboard and management could be simplified."

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

"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."

More Pure FlashArray X NVMe cons

"We experienced some concerns during a previous firmware upgrade when the controllers became unresponsive, which affected operations."

"I do not like having to use VPLEX for synchronous replication, as opposed to having the store software built-in."

"The maintenance is a bit expensive. The service and support are there for three years, but after the third year, it is pretty pricey for renewal."

"Earlier the quality of support was excellent, but now it has deteriorated. We do not get quick support, and we have to wait longer to get the support."

"I would rate Dell PowerStore seven or eight out of ten. There are always areas for improvement, which I mentioned earlier."

"Could be improved by including a synchronizing feature for the file systems."

"Where the system needs to improve is by adding more enterprise features like replication on other sites. We would also like it to be much more aligned with the VMware version. For example, today we have two different versions of VMware ESXi running to keep the PowerStore online. It would be better if the software cycling was faster."

"One improvement I would suggest relates to the service that pings Dell when there's an issue. I would say it needs to be more transparent."

More Dell PowerStore 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 licensing is on a yearly basis."

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

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

"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'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."

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

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

More Pure FlashArray X NVMe pricing and cost advice

"Licensing is very simple. Everything is included in the basic license. There are no concerns about having to pay to add a feature. Everything is there."

"As compared to others, PowerStore is cheaper."

"PowerStore's pricing is reasonable."

"Dell PowerStore is more expensive than Dell EMC Unity All Flash. Dell PowerStore's performance metrics were way higher than what Dell EMC Unity All Flash offered."

"We purchased it with a five-year warranty."

"The pricing rates at seven out of ten as it is considered overpriced. Entry-level models are reasonably priced, starting around $30,000 for a base model with 6 drives. However, upgrades become costly - adding 6 additional drives can cost another $30,000."

"The solution’s pricing is always too high."

"Dell PowerStore is not a cheap solution."

More Dell PowerStore pricing and cost advice

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

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