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.

Integrated AI and clustering enhance storage operations effectively

I promote and recommend Dell PowerStore for all workloads to my clients and customers. Most of my customers have one appliance per site. Approximately 80% of my customers have Dell PowerStore implemented in their data centers. We always use CLS as another Dell solution for cybersecurity and data security. The CLS is integrated with the Data Domain, PowerProtect Data Domain, not with Dell PowerStore. Windows, Linux, and some customers use Red Hat or SUSE. We have many operating systems working with Dell PowerStore in the same environments and data centers. CloudIQ and Storage IQ are used by some customers, but Apex AIOps has not been widely adopted yet. Dell PowerStore has integration with VMware and Kubernetes. Most workloads work fine and have very good integration with Dell PowerStore, except for one or two specific workloads in the market. On a scale of one to ten, I rate Dell PowerStore a nine.

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

"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."

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

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

"It has good, reliable, fast storage."

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

"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."

"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."

"The solution is scalable."

More Pure FlashArray X NVMe pros

"Dell PowerStore has benefited our organization through cost savings."

"The beauty is the simplicity - customers can manage multiple workloads from a single dashboard with scale-out architecture."

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

"The most valuable feature is that it is easy to use this frame. I am a SAN administrator, but I was able to train my colleague, who had only been a VMware administrator, on the PowerStore in about half a day. Now he's autonomous in assigning volumes and creating data stores..."

"The return on investment since switching to Dell PowerStore has been really good."

"It's really good, price-wise. It's cost-effective."

"Updates come with enhancements. Each time we do an update, there is an enhancement, like new features, which is extraordinary. Other companies would try to charge for all that, but the enhancements just come with it."

"This solution is very useful to us as we use it internally for all of the services that we need. We use it as a lab and we showcase new technology to the customers and how it can help them going forward."

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

"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."

"Our use cases require more multi-tenant capabilities and additional VLAN interfaces for separating different customers. We currently use it to provide storage, sometimes shared storage, to different customers, but it is less flexible in comparison to a dedicated solution."

"We need better data deduplication."

"The tool's pricing is higher than competitors."

"Maybe the price can be reduced since the solution is very expensive."

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

"In the future, I would like to see integration with enterprise backup systems."

"The software layer has to improve."

More Pure FlashArray X NVMe cons

"When we go to buy or populate more drives in the storage array, they're so expensive. If they could lower the cost for components, we would definitely expand them more and be more inclined to buy more storage units, but it's currently a price crunch for us."

"There are certain shortcomings with the technical support team of Dell PowerStore, where improvements are required."

"While using Dell PowerStore's interface in our organization, we sometimes miss out on some information."

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

"I wish there were more options to fine-tune things. Some of the information requires deeper investigation to get data efficiency per data store."

"It's also only supported with a limited amount of switches."

"The biggest area in PowerStore that needs improvement is the overall visibility within the ESX environment."

"The support is not very good."

More Dell PowerStore 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

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

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

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

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

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

"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."

"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 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."

More Pure FlashArray X NVMe pricing and cost advice

"The price is high compared to the Tunisian market."

"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."

"With compression, we were able to have a solution within our company's budget. We include a clause in the contract with Dell that states if the compression ratio is not met, we will adjust the workload accordingly."

"Dealing with the licensing part of the product is very simple, especially considering the fact that we don't have many licenses associated with the tool."

"The software features are included in the pricing without any additional purchase requirements."

"The pricing structure and licensing model of Dell PowerStore are very good and I like it. We chose it because it was reasonably priced and met our requirements"

"We only have a single machine and we are currently using half of the hard disk slots. We have asked for an upgrade for the rest of the hard disks but, from my point of view, it costs too much. We have 12 to 15 hard disks inside and if we try to upgrade only the hard disks, it costs the same as the complete system. This is something I don't understand."

"I rate the price of Dell PowerStore a seven out of ten."

More Dell PowerStore 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."
