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

"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 feature of this solution is reliability."

"Technical support has been helpful and responsive."

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

"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 best features of Pure FlashArray X NVMe include the volume snapshot capabilities, which allow us to save most of the storage space by volume snapshots periodically."

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

"The duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."

More Pure FlashArray X NVMe pros

"Dell PowerStore is more cost-efficient than other solutions."

"The biggest return on investment for me when using Dell PowerStore is scalability; scalability is key, and I can amplify that by saying we have redundancy between two sites—if something goes down, we have to manage it, but we want to do it proactively."

"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."

"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."

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

"PowerStore is easy to use. All the drives use soft encryption. To upgrade it, you download the app, and it runs by itself. It's very easy to deploy, share, and create volumes."

"The solution is resilient and reliable, the support is very good, it performs fast with excellent IOPS, and their deduplication and compression ratio features are excellent."

"The solution is stable."

More Dell PowerStore pros

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

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

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

"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 most valuable feature of the solution is its upgrades, as we don't have to do much homework because of its different controllers."

"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."

More IBM FlashSystem 9100 NVMe pros

Cons

"We need better data deduplication."

"The software layer has to improve."

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

"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."

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

"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."

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

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

More Pure FlashArray X NVMe cons

"Speed is something I would like to maximize in its features, as there is a need for speed."

"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."

"The only improvement that might be required, though not significantly, relates to the features that allow for support, specifically the call home features."

"The support team should have more people with experience in the solution's installation process, as it is one of the areas where I see certain shortcomings."

"The pricing point must have better positioning. It is somewhat expensive compared to the competition."

"Dell PowerStore has deduplication, but it may need more enhancement because in our case, it was not as efficient as Dell Data Domain."

"Some of the data metrics we get out of Pure from a support perspective online are a little bit more robust than the Dell PowerStore metrics, but it's not a negative against Dell."

"One thing they need to work on is creating an app sync or the Metro Cluster functionality. Currently, it requires a different hop as we have to add multiple switches to build that functionality for replication from one data center to another. If that could be bundled in a base Dell PowerStore by default, it would be great."

More Dell PowerStore cons

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

"Deduplication and compression should be improved."

"IBM FlashSystem 9100 NVMe is an expensive solution, and its pricing could be improved."

"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."

"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.""

"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 solution's compression feature could be better."

"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."

Pricing and Cost Advice

"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."

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

"The product is expensive."

"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."

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

"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."

"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."

More Pure FlashArray X NVMe pricing and cost advice

"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."

"There are no separate licenses required as all the basic licenses are included in the bundle."

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

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

"The solution’s pricing is always too high."

"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 price of Dell PowerStore could improve. The price should be managed more compared to Huawei Dorado or IBM All-Flash series."

More Dell PowerStore pricing and cost advice

"The solution's price is competitive."

"The product has an average cost."

"Price-wise, the solution offers excellent pricing to its users. In short, the prices offered by the solution are competitive compared to similar solutions."

"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 the FlashSystem 9100 NVMe is reasonable."

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

"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."

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