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.

Quotes from Members

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

Pros

"It's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."

"It has benefited my organization because it has reduced time to insights."

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

"The high availability of the product is the most valuable feature."

"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."

"It is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."

"The most valuable feature of this solution is its ease of use."

"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."

More Pure FlashArray X NVMe pros

"The tool's most valuable features are compression and speed."

"The way you're able to manage all your PowerStores as one solution is very good for us. PowerStore enables you to federate or cluster multiple appliances with automated load balancing. In terms of management, it's helpful that we can do it from a single interface where we're able to manage multiple PowerStores. When you have multiple PowerStores it works intelligently by running the workloads based on the needs of the infrastructure."

"The solution's migration feature is very valuable, but the most valuable thing is that more features appear with every iteration of the software."

"We used Cloud IQ. The central management and outside support functionality were great since we had systems all over the world."

"The biggest return on investment for me when using Dell PowerStore is scalability; scalability is key, and I can amplify that by saying we have redundancy between two sites—if something goes down, we have to manage it, but we want to do it proactively."

"I rate Dell PowerStore a perfect 10 out of 10."

"It provides a big benefit when upgrading a new VMware environment. For example, in a big environment with 10 to 30 ESXs, you can take everything and put that into PowerStore. So, it is cost-effective, which is very important and has been massive for us. You reduce almost 80% from the hardware and work directly from PowerStore. Building hardware, especially in a big VMware environment, is a big issue for my organization."

"The deduplication functionality provided by the solution is fairly good. The speed offered by the product is enough for our organization."

More Dell PowerStore pros

"The FlashCore modules support more value to the architecture due to their unique characteristics."

"It's easy to use, has good stability, and many features."

"The most valuable features of IBM FlashSystem 9100 NVMe are its steady performance and usefulness in high-traffic environments."

"IBM FlashSystem 9100 NVMe is one of the leading storage systems in the world...I rate the solution's stability a ten out of ten."

"The most valuable feature is the speed."

"A key feature is that compared to storage systems that we've been familiar with over decades, IBM simply does not fail. The reason is that IBM is the only manufacturer that engineers its own flash module, and there is a key architectural difference from everything else that we have seen in the market. The difference is that the flash module has the computational capability, which allows reliability and capacity enhancements to be uploaded from the main controllers and run in each module. So, each of the flash drives becomes its own little storage system, and that is extremely effective architecture. In this field, with this type of system, IBM has made a statement. They've never had one of these modules cause an outage. So, the failure rates on these things are just in a whole different universe from what we were accustomed to."

"Its ease of use, performance, and hardware compression is very useful feature."

"The storage serves the virtual environment. Most of our applications run in the virtual environment, and it serves nearly 30% of the bank's capacity."

Cons

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

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

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

"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."

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

"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."

"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."

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

More Pure FlashArray X NVMe cons

"Customer service is good, though if you are running into some issues where you have to chase after them or they do not understand what is going on, overall it is pretty good."

"When you create a case on Dell's support website, you don't always get someone who is experienced in the kind of systems you need help with...making it an area where Dell's support team needs to make improvements."

"PowerStore's management console could be improved."

"Customer service is good, though if you are running into some issues where you have to chase after them or they do not understand what is going on, overall it is pretty good."

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

"In terms of improving Dell PowerStore, they should have simplified documents available for customers, not just for the support team."

"The management UI is pretty decent and gets the job done, but the upgrade process is challenging."

"The replication part needs improvement, particularly the integration of RecoverPoint."

More Dell PowerStore cons

"I'd like to be able to connect to tape drives behind the storage device to back up the tape if need be. We have all of our storage running in all-flash, and we make a copy on tape. Currently, when we want to hook up tape drives, we have to add some extra equipment, which is a little bit complex. We want IBM to add a feature where we could install a tape into the storage so that we can connect it through a single pane of glass. We'd like to have a feature in the IBM flash storage system so that we can connect backup tape drives through the IBM storage system and we can manage the backup tape from the storage system."

"There could be a possibility of not requiring to buy a new box while upgrading to a newer version."

"In the future, the limitation is upgrading the same storage by adding a shelf to the desk. There is a limitation in the backend connection between the storage and extended shelf."

"IBM FlashSystem 9100 NVMe is an expensive solution, and its pricing could be improved."

"The efficacy of the GUI in IBM FlashSystem 9100 NVMe could be enhanced, and it would be beneficial to include a feature that can prevent ransomware attacks."

"There is a tool provided by IBM for repairing batteries which can only be utilized by those who have an IBM technical advisor under service contract. However, for individuals who do not have such a contract, the tool can be difficult to use and requires a zip file copy. I believe that it would be greatly beneficial if the tool were made more user-friendly and accessible for all individuals who need to repair batteries."

"IBM's support is not good. I experienced a big problem where I opened the console IBM Storage and would see that something was broken. I called the call centers, and I said, "I have a problem. My drive is not working." They want me to give them the serial number, I gave it to them and they told me "I cannot find your product. Your product is not here.""

"I would like to see IBM products become more affordable because they can be quite expensive, which limits their accessibility to a broader customer base."

Pricing and Cost Advice

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

"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."

"The licensing is on a yearly basis."

"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."

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

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

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

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

More Pure FlashArray X NVMe pricing and cost advice

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

"The solution's price was comparable to other products for the use case, size, and setup."

"The pricing is good. There's no need to pay for a license; it's all-inclusive."

"If we use the 500 or 1000, the licensing and pricing are reasonable. PowerStore can compete with any vendor and the price isn't that expensive."

"There's still a cap on the upgrade path, where you can consume all the engines within the frame before you have to go to another frame... Normally, we exceed the IOPS on the frames before we can ever exhaust the storage, so anything they can do to help us avoid stranded storage capacity, capacity that we couldn't get to, would be beneficial."

"In terms of licensing, my organization has Dell Technologies End User License Agreement (EULA), but I don't know exactly how it works, though it is a big bundle of licenses for Dell Data Domain, Dell EMC Unity XT, Dell PowerStore, Dell ECS, and all such kinds of storage arrays."

"Dell PowerStore is not a cheap solution."

"The price is not cheap, but it's worth it for the features you get from the storage. If you can afford it, you are probably buying the best solution that you can have for this virtual environment."

More Dell PowerStore pricing and cost advice

"The solution's price is competitive."

"The product has an average cost."

"The tool's pricing is competitive."

"On a scale of one to ten, where one is a low price and ten is a high price, I rate the pricing an eight."

"There are pricing options from the mid-rand to the high-range, of which the suitability depends upon the requirements."

"Price-wise, the solution offers excellent pricing to its users. In short, the prices offered by the solution are competitive compared to similar solutions."

"The price of IBM FlashSystem 9100 NVMe is less than Dell. For upgrades, the Dell solutions are more expensive."

"The solution is priced well."
