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

"On a scale of one to ten, I rate Pure FlashArray as ten."

"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."

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

"The most valuable features of this solution are its ease of use and performance."

"The latency is good."

"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 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 solution uses newer technology for deduplication and compression."

More Pure FlashArray X NVMe pros

"PowerStore's compression ratio is a valuable feature for our VMs because it gives us a lot back."

"The most valuable feature of the solution for me is the deduplication part, especially since most of the servers in our organization are Windows-based servers."

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

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

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

"You can add compute and capacity independently. We have sized the solution based on our current needs, but in the future we can choose to increase capacity if we grow our activity in the market. And if we have more business in our monetary system, we can increase compute. The ability to choose what we increase is a good feature."

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

"The major thing is the performance issues we had previously; now, it is a primary storage for the client, and it was the best way where they even reduced to 95 percent where they had almost weekly P1 or P2 tickets, which reduced to hardly once a month or quarterly once."

More Dell PowerStore pros

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

"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."

"It is a very stable solution."

"Good performance with a user-friendly UI."

"The most valuable feature is the speed."

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

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

More IBM FlashSystem 9100 NVMe pros

Cons

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

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

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

"We need better data deduplication."

"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."

"Right now, the box itself is just strictly working as a backend storage system. It would be fantastic if we could access it directly like a NAS device through network access or SIS drives. I think they have an interface, but I am not sure how good it is. If we could address a box directly on the network without having to go through a server, it would be great. The replication schemas could be improved. We are not using replication on the storage level right now. We use a different type of replication. If their replication would be as good as the one that we have, I would probably run the replication schema because it might be faster, but I don't know that for a fact. So, I cannot say that they have good replication. All I can say is that they need to inform us better."

"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."

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

More Pure FlashArray X NVMe cons

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

"I have not seen anything specific. The only thing I can think of that needs improvement is the price."

"Where the system needs to improve is by adding more enterprise features like replication on other sites. We would also like it to be much more aligned with the VMware version. For example, today we have two different versions of VMware ESXi running to keep the PowerStore online. It would be better if the software cycling was faster."

"When comparing compression and deduplication technology in Dell PowerStore with Pure Storage, there is room for further improvement."

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

"The solution didn't have all of the features we needed."

"Could be improved by including a synchronizing feature for the file systems."

"The data resiliency and cybersecurity features of Dell PowerStore are just normal and would be considered medium; we need additional components such as cybersecurity vault for increased resilience."

More Dell PowerStore cons

"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."

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

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

"The solution's compression feature 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.""

"The pricing should be more competitive."

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

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

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."

"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."

"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."

"The product is expensive."

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

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

"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."

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

More Pure FlashArray X NVMe pricing and cost advice

"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."

"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 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."

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

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

"The solution is expensive."

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

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

More Dell PowerStore pricing and cost advice

"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."

"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."

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

"The solution's price 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 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."
