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.

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

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

More Pure FlashArray X NVMe pros

"The improvement is massive; even a couple of milliseconds makes a significant difference to our production throughput, allowing products to leave the door more efficiently, which also cuts back on overtime and ensures we can complete our daily tasks in the required hours."

"The most valuable feature is the functionality of the integration between the storage and the domain."

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

"Overall, we're quite happy with the product because we can move the data that is stored on more than 10 of our current storage devices to a single PowerStore."

"The features I like most about Dell PowerStore are the reliability, the time, and the performance."

"The most valuable feature of Dell PowerStore is the metro cluster because we have two data centers and high availability."

"The most valuable feature of Dell PowerStore is Metro Volumes."

"When compared to Pure Storage, Dell PowerStore's cost was quite attractive."

More Dell PowerStore pros

"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 most valuable feature is the speed."

"Good performance with a user-friendly UI."

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

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

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

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

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

Cons

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

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

"We would like to see more visibility into garbage collection and CPU performance in the GUI."

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

"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."

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

"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. Storage replication should be essential, and the analytics should not incur extra charges."

More Pure FlashArray X NVMe cons

"We did have one issue when an update stopped the phone-home solution, however they fixed that via support."

"The setup process could be improved. We had some issues regarding configuration and the time it took to do things. It wasn't specifically the people we worked with, but more the process and how it's done. They can work on that."

"I would like to see additional features or functionalities for the Metro in Dell PowerStore, especially because there are a few workloads still not supported."

"Some areas of Dell PowerStore that could be improved include reporting features, such as performance reports, which are lacking compared to VMAX and PowerMax."

"Earlier the quality of support was excellent, but now it has deteriorated. We do not get quick support, and we have to wait longer to get the support."

"We have not seen an ROI and it would be good to have an ROI calculator made available by Dell."

"The maintenance is a bit expensive. The service and support are there for three years, but after the third year, it is pretty pricey for renewal."

"Coordination is occasionally a challenge; involving intermediary partners can make the support process less direct and lead to setup hurdles."

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."

"The ZIO interface could be improved."

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

"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 support could be better."

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

"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'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."

Pricing and Cost Advice

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

"The product is expensive."

"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."

"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."

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

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

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

"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."

More Pure FlashArray X NVMe pricing and cost advice

"Dell PowerStore is more expensive than Dell EMC Unity All Flash. Dell PowerStore's performance metrics were way higher than what Dell EMC Unity All Flash offered."

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

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

"We only have a single machine and we are currently using half of the hard disk slots. We have asked for an upgrade for the rest of the hard disks but, from my point of view, it costs too much. We have 12 to 15 hard disks inside and if we try to upgrade only the hard disks, it costs the same as the complete system. This is something I don't understand."

"The software features are included in the pricing without any additional purchase requirements."

"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 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."

"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."

More Dell PowerStore pricing and cost advice

"The solution's price is competitive."

"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."

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

"The solution is priced well."

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

"The tool's pricing is competitive."
