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

"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 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."

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

"I appreciate the performance."

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

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

"It has good, reliable, fast storage."

More Pure FlashArray X NVMe pros

"The main feature of Dell PowerStore is its support for NVMe as well as hybrid solutions."

"The most valuable feature is the encryption in the loop because we can manage data center data from a different perspective, reducing the space used while growing data using the same equipment."

"The most valuable feature of Dell PowerStore is its immutable storage, which is what we are looking for. It offers high protection in terms of ransomware protection."

"The resilience in Dell PowerStore benefits my company from an auditing perspective because we know we have that resilience in place."

"The thing that I appreciate the most about Dell PowerStore is how easy it is to upgrade; the upgrade process is very simple, and I really appreciate how easy it is to connect my hosts to Dell PowerStore, as the environment automatically detects new fiber channel HBA ports for all the hosts that we connect to."

"Dell PowerStore has impacted my organization positively as it is a very easy system to use, so from an operational standpoint, I would emphasize its ease of use."

"The most valuable feature about Dell PowerStore is speed and reliability."

"Benefits of Dell PowerStore compared to Unity 400 and 650F, which we were previously using, are significant: we benefit from extensive deduplication for non-database applications, which saves us a considerable amount of costs, and the performance has improved dramatically due to advancements in technology, such as TLC disks and NVMe technologies."

More Dell PowerStore pros

"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."

"It is a very stable solution."

"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."

"The features I find most valuable include its use for storage and performance."

"It is a very stable product. Stability-wise, I rate the solution a ten out of ten because we did not face any issues in the last three years."

"What I like about the product are its high availability, maximum efficiency in performance, and its ability to handle a high level of I/O operations."

"The solution is more available for IOPS warehousing, resolving issues, and reporting than other products."

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

Cons

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

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

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

"We need better data deduplication."

"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."

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

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

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

More Pure FlashArray X NVMe cons

"If I could improve Dell PowerStore, I would suggest that integrations into backup platforms be a little more streamlined."

"I would like to see a Snapshot feature. Currently, it is unable to occupy the capacity."

"I would suggest that Dell PowerStore could come with various other features, such as a hybrid model apart from only all-flash, which would really help the customers."

"Dell PowerStore could be improved by integration into the Dell automated platform, which would allow us to see it and perform the upgrades right from there."

"Dell PowerStore is too expensive, and it could be less complicated. It isn't as user-friendly as other options, especially regarding the user interface."

"Reporting is an area that could be improved. It's very simplistic sometimes, and some of the very technical guys on my team want to see more of the details and be able to massage the report a little bit better."

"One of the big differences when we were looking at Pure is that they had more of an in-place upgrade option going forward, kind of future-proofing things. We hear Dell is working towards that, but they weren't quite there, especially three years ago."

"It could be improved to be cheaper for us."

More Dell PowerStore cons

"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."

"Other vendors have included a block and file system. IBM doesn't include a file system. And yet, it's very necessary for all organizations' networks to have file systems. We have other systems for the file system, however, ideally, we would like to have one system with these features."

"The solution's compression needs to be improved, as it's not the best."

"Deduplication and compression should be improved."

"IBM is currently not offering volume-based encryption or compression, while other brands or IBM's competitors are doing it."

"The storage system itself should have built-in capabilities for different ransomware attacks."

"The support could be better."

"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.""

Pricing and Cost Advice

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

"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."

"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."

"Pretty much everything that you need is licensed when you buy the product. Licensing to me is different than the maintenance cost, but they can bleed into one another. We buy the product, and we expect three years of support bundled into what we negotiate on our storage arrays. I would start to see maintenance costs going into the fourth year, but we're not there yet."

"The licensing is on a yearly basis."

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

"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."

More Pure FlashArray X NVMe pricing and cost advice

"The rate is always too high. Nobody likes paying for it. I have not seen a client yet who says that the price should be higher. Initially, people look at it, but when they see what the benefits are, it is a no-brainer. We can give them good pricing at the outset."

"The price of Dell EMC PowerStore could be better, it is a bit expensive."

"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."

"We are happy with the pricing that we get from Dell."

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

"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 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."

"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."

More Dell PowerStore pricing and cost advice

"It's a lot less costly than cloud storage. People get surprised by the cost of cloud storage, which is extremely expensive and four or five times the cost of storage on-premises. People don't realize what they're spending on storage until they start getting bills from Amazon, Microsoft, and others. This is a good way to reduce your cloud storage expenses."

"The solution's price is competitive."

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

"The price of the FlashSystem 9100 NVMe is reasonable."

"The solution is priced well."

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

"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."
