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 has benefited my organization because it has reduced time to insights."

"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."

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

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

"We are satisfied with the performance as it is significantly faster compared to traditional storage options."

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

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

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

More Pure FlashArray X NVMe pros

"Overall, I rate Dell PowerStore a ten out of ten."

"Pricing is very good. It's very competitive against those of all the others that I looked at in the marketplace, such as Hitachi, IBM, HP, and Pure. Dell is right there in the mix as far as providing the best price point as well as meeting the performance requirements that we have."

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

"Dell EMC PowerStore is scalable."

"The data encryption is good and available in a standard license. There are snapshot and backup capabilities."

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

"The best features of Dell PowerStore include the effective capacity, which I believe is its strongest feature, and the dynamic RAID of disks."

"The administration tools take advantage of machine learning and make recommendations to the admins, and that makes the administration easier."

More Dell PowerStore pros

"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."

"IBM FlashSystem provides the same software on each box, including virtualized solutions."

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

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

"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."

"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."

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

More IBM FlashSystem 9100 NVMe pros

Cons

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

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

"It is on the expensive side."

"It feels more suitable for small and medium-sized businesses rather than enterprises."

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

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

"One point I'd like to improve is that the tool should start selling small boxes again. It discontinued some products and is focusing on bigger, more capable boxes, neglecting the SMB market. Even though it's not a big market, it shouldn't have removed them."

"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

"There seems to be a lack of a price range in the small company, small medium company segment."

"Users can be enrolled in lifecycle extension with pro support. The pricing for that is too high for PowerStore."

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

"Dell PowerStore is a good solution overall, but some models could support hypervisors better by allowing for more customization and flexibility for customer needs."

"The only thing is that with PowerStore, we don't have a solution for the file object."

"The pricing could be lower. It is very expensive."

"The cost always has room for improvement."

"There are some management issues in Dell PowerStore. I have managed several pieces of Dell PowerStore's hardware area, and I could feel that it was almost like a step back in certain areas when it came to the management interface."

More Dell PowerStore cons

"The support could be better."

"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."

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

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

"The ZIO interface could be improved."

"There could be a possibility of not requiring to buy a new box while upgrading to a newer version."

"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."

"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."

"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."

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

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

"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."

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

"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

"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 solution is 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."

"Licensing is very simple. Everything is included in the basic license. There are no concerns about having to pay to add a feature. Everything is there."

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

"It is easy to work with Dell from the licensing perspective."

"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."

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

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 NVMe is less than Dell. For upgrades, the Dell solutions are more expensive."

"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 product has an average cost."

"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 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."
