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

"The database workloads are pretty fast because I frequently move data from here to there."

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

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

"It has good, reliable, fast storage."

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

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

"The solution uses newer technology for deduplication and compression."

More Everpure FlashArray X NVMe pros

"The simplicity and ease of use have been very valuable features. I have a very small team, and only half of the team is well versed in the HP product. Whereas if I bring PowerStore in, everyone can learn it because it will be new on the floor."

"I am directly involved in working with Dell PowerStore from the beginning in sales, pre-sales, through to implementation and execution in the projects, and it works perfectly."

"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 software upgrades are all included for no additional charge."

"While I note some potential for future enhancements, Dell PowerStore is already a leader in customer satisfaction."

"I've tested quite a few storage systems, and I find Dell PowerStore really highly suited to modern, diverse environments."

"The solution is extremely stable."

"The most valuable features in Dell PowerStore are the Metro Volume features that are built-in without requiring an additional component."

More Dell PowerStore pros

"The high performance and high availability improved our overall processes."

"The most valuable feature of IBM FlashSystem 9100 NVMe is the snapshot. We use it daily for all of the storage units."

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

"IBM FlashSystem 9100 NVMe is easy to use and comes with good performance."

"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."

"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."

"Good performance with a user-friendly UI."

"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."

More IBM FlashSystem 9100 NVMe pros

Cons

"Managing data isn't difficult for me. The performance is usually perfect, but we sometimes have capacity problems."

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

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

"I would like to see replication and DR features in the next release of this solution."

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

"I would like to see some AI features that would allow arrays to intelligently identify threats or unusual behavior in the data pattern and give an alert."

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

"You cannot tag a LUN with a description, and that should be improved. What I like on the Unity side is that when I expand LUNs or do things, there is an information field on the LUN. This is the Information field that you can tag on your LUNs to let yourself know, "Hey, I've added this much space on this date". Pure lacks that ability. So, you don't have a mechanism that's friendly for tracking your data expansions on the LUN and for adding any additional information. That's a downside for me."

More Everpure FlashArray X NVMe cons

"Upgrading an old model to a new one can be complex, particularly when using VMware."

"There could be better reporting."

"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."

"There are many vulnerabilities that we cannot mitigate related to the administration interface."

"I would have preferred if Dell PowerStore could have a common operating system across all their products, as that would be of great advantage."

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

"I have experienced some downtime with Dell PowerStore, particularly due to a bug with Emulex HBAs during an upgrade process."

"We'd like to see some improvements on the security side."

More Dell PowerStore cons

"The ZIO interface could be improved."

"I would like to have replication functionality built directly in the product, rather than having to use a separate device for this."

"In the FlashSystem 5200, there were only four ports of 32 fiber channels for the architecture. This has been resolved in the new generation."

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

"IBM FlashSystem 9100 NVMe is currently at the end of its lifespan and will soon become obsolete in the markets."

"The tool's architecture is complex. It also needs to add data utilization reports."

"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."

More IBM FlashSystem 9100 NVMe cons

Pricing and Cost Advice

"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."

"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 product is expensive."

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

"The licensing is on a yearly basis."

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

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

More Everpure 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."

"We are currently using Dell PowerStore for our smaller storage and there is no competition for pricing."

"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 the pricing and licensing department, the product is always too expensive."

"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"

"The pricing structure and licensing model of Dell PowerStore are pretty decent. It's pretty competitive."

"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."

"Dell PowerStore is not a cheap solution."

More Dell PowerStore pricing and cost advice

"The tool's pricing is competitive."

"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 solution's price is competitive."

"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."

"Compared to its competitors, IBM's offering is the most cost-effective."

"The price of IBM FlashSystem 9100 NVMele can be considered affordable when taking into account the operating system that is required for it to function properly. This operating system, which is licensed by IBM, may carry a higher cost, but it is worth the investment for larger corporate entities, such as insurance companies, Fortune Five companies, and banks, who make up a significant portion of their target market. The FlashSystems are designed for larger corporations and multinational enterprises, and may not be the most cost-effective solution for smaller businesses."

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

"The solution is priced well."
