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.

Has supported long-term data protection and backup while requiring better part availability and pricing options

For monitoring purposes, we normally use flash access storage exclusively. We utilize a hybrid system because we need performance, combining NL-SAS for the volume and SAS flash to use as a fast cache system that provides more IOPS. We normally implement RAID 10, which we prefer over RAID 6's n plus 2 combinations. We utilize it for data redundancy, even with write intensity on. Regarding the unified storage architecture for NetApp FAS Series, we normally opt for exclusivity unless budget constraints exist. Our IOPS are very high, reaching somewhere about 50k to 150k or 1.150k. The high performance ensures minimal latency. An advantage we've seen with NetApp FAS Series is that snapshots provide very rapid backup and fast recovery. We basically use snapshots for data protection as first-level protection, with deduplication between the two storages serving as second-level protection.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

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

"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."

"Speed has definitely been a big improvement for us; we were running a bunch of iSCSI to EMC VNX and that had a gigabyte bottleneck, and now, since we're running through a true fiber channel to the Pure array, we're getting 32-gigabyte bandwidth, which means the speed and accessibility for our users and our customers have definitely improved."

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

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

"The initial setup was extremely simple and straightforward."

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

"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 Everpure FlashArray X NVMe 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."

"The most valuable features of IBM FlashSystem 9100 NVMe are its steady performance and usefulness in high-traffic environments."

"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."

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

"The product is a game-changer; IBM changed the game architecturally by moving computational resources into the flash media."

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

"You get value for money, because the product is good in terms of control failure."

More IBM FlashSystem 9100 NVMe pros

"It gives us the performance we need and the reliability we need to make sure that our systems have the uptime that our internal customers demand."

"This solution provides us with easy management and great vendor support."

"You can use different protocols at the same time, and monitoring is also very easy in NetApp FAS Series, with a free tool available for monitoring."

"The best feature is its ONTAP product line for Ransomware protection. It also has features for file storage and block storage. The solution is stable. We've had no issues with it. The tool is scalable and meets our requirements. The technical support and the supporting partner are great. The initial setup is straightforward. It is very easy to maintain the product. The feature set is excellent. I recommend the solution."

"I love those innovative healthcare data solutions that let me securely manage vast amounts of patient data (32.9 PB), use and share it enterprise-wide, and gain efficiency of scale through cloud solutions and virtualization."

"The support is very good."

"It changed the way we do Disaster Recovery (DR) around NetApp replication."

"NetApp is also a very stable company that offers various storage options at the highest level of build and reliability."

More NetApp FAS Series pros

Cons

"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."

"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."

"The solution should improve its logon requirements."

"There are some challenges with data encryption and reduction."

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

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

"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."

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

More Everpure FlashArray X NVMe cons

"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."

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

"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."

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

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

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

"The pricing should be more competitive."

"Currently, when we want to hook up tape drives, we have to add some extra equipment, which is a little bit complex."

More IBM FlashSystem 9100 NVMe cons

"I get caught in the upgrade matrix quite a bit, which is an indication that it hasn’t been tested."

"Its licensing cost can be improved."

"We're supposed to have used NetApp FAS Series for replication, but then one of the nodes failed, and then it's taken us some time to bring it up."

"The one aspect of the solution that's negative for us is also more unique to us due to the fact that we did a MetroCluster. The tiebreaker piece that does the monitoring of the two different locations, and determines if one is not talking to the network normally (or if it's truly down) is a little difficult. It feels like it was not designed from the beginning to fit well into the other pieces. It feels like it was thrown in at the last minute and it is not smooth."

"NetApp is costly when compared to Dell."

"The performance needs to be improved."

"There is room for improvement in deployment and configuration processes."

"One area that needs improvement is the hyper-converged solution. Although NetApp has a solution, compared to Nutanix, it falls short."

Pricing and Cost Advice

"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."

"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."

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

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

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

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

"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."

More Everpure FlashArray X NVMe pricing and cost advice

"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 the FlashSystem 9100 NVMe is reasonable."

"The solution is priced well."

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

"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 product has an average cost."

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

More IBM FlashSystem 9100 NVMe pricing and cost advice

"The tool is expensive."

"The process for going to cluster mode is expensive."

"I've sold arrays for as little $20,000 USD and as high as $300,000 USD."

"We purchased it for four years, and it wasn't expensive. It was reasonable. Every company has a different agreement with NetApp. We got everything we wanted with all the bells and whistles and all the features and functionalities."

"We are on a perpetual license."

"The price it not low, but comparing features to other vendors, the price can be balanced."

"The price, compared to competitors, is quite high."

"Cost effective storage for all performance levels (including all-flash)."
