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 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."

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

"The solution is very straightforward to set up."

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

"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."

"The solution is scalable."

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

More Pure FlashArray X NVMe pros

"Dell PowerStore is a great machine for storage with big performance when data is needed."

"I have seen a return on investment with Dell PowerStore as it does what we wanted it to do. It gives me peace of mind."

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

"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."

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

"Reliable, with comprehensive features and a well-established support base."

"I have seen some return on investment. Since we were refreshing our infrastructure, the return on investment has been that I am able to concentrate my time on high-level items rather than small-level items that come from the aging infrastructure that we had before."

"Dell PowerStore provides measurable benefits in performance because it uses all-flash disks while our old storage relied on mechanical hard disks."

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."

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

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

"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."

"Good performance with a user-friendly UI."

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

"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."

"There are many valuable features of IBM FlashSystem 9100 NVMele I have found to meet my needs. Specifically, the maintenance cycle is a standout feature of this solution. The main component of the IBM FlashSystem 9100 NVMe is the maintenance of the batteries, which have a predetermined and reliable four-year life cycle. This is in stark contrast to other solutions that may use spinning disks, which can fail unexpectedly, causing unwanted downtime and maintenance. Having a predictable maintenance cycle is a significant advantage and has made this solution a preferred choice for me."

Cons

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

"They could add more support for file storage and different types of storage."

"The software layer has to improve."

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

"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."

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

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

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

More Pure FlashArray X NVMe cons

"Many customers are looking for a cyber recovery feature included in PowerStore. We would like to see this added in a future release."

"Sometimes, you have to go back and forth with the technical support team, where they want you to do something you've already done."

"From an entry-level perspective, PowerStore 500T has limited expansion capabilities."

"The only problem is that it came out a bit early; before version 3.6, it didn't have the features that customers expected, and it was difficult to work with because we didn't have metro-cluster."

"The UI should be a little more user-friendly to manage."

"If I could improve Dell PowerStore in any way, I would enhance the socialization of the good skills this equipment has, improving communication with partners as the good features are inside Dell PowerStore, however, many customers don't know how powerful it is."

"The design needs to be something similar to Pure Storage. It would be beneficial if there are different color or lighting options for different product casings."

"Monitoring is an area of concern in the product where improvements are required."

More Dell PowerStore cons

"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."

"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."

"The solution's compression feature could be better."

"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."

"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."

"The pricing should be more competitive."

"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."

"The ZIO interface could be improved."

Pricing and Cost Advice

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

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

"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."

"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."

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

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

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

"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."

More Pure FlashArray X NVMe pricing and cost advice

"As compared to others, PowerStore is cheaper."

"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."

"PowerStore's pricing is reasonable."

"Dell PowerStore is affordable and the license is just a face license which is great."

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

"It is expensive compared to one of its competitors."

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

"Dell PowerStore charges for the hardware warranty every three years. The price will depend on the storage model or how much hardware it has."

More Dell PowerStore pricing and cost advice

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

"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."

"Compared to other solutions, the cost of IBM FlashSystem 9100 NVMe is reasonable, with a one-time payment of around $70,000. However, additional support is available for $25,000 for three years. The overall maintenance cost is steep."

"The solution is priced well."

"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 tool's pricing is competitive."

"The solution's price is competitive."

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