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.

Quotes from Members

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

Pros

"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"The most valuable features of this solution are its ease of use and performance."
"On a scale of one to ten, I rate Pure FlashArray as ten."
"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"Technical support has been helpful and responsive."
"It has benefited my organization because it has reduced time to insights."
"FlashArray has some fresh efficiency features. I've never seen a storage solution with a compression rating this high before. It's at least 4-to-1 on Oracle databases. It's the best flash storage for Oracle."
"Pure FlashArray X NVMe will quickly overcome all the hurdles you face, including network and latency issues."
"One of the most valuable features is that it's very easy to use and configure. It used to be more difficult, but now it's almost flawless."
"When it comes to the interface of the solution we did not encounter any challenges. Additionally, the solution has good documentation."
"The most valuable feature in demand is virtualization and its support storage of virtualization features."
"The solution is very easy to configure and use."
"User friendly management interface."
"IBM FlashSystem has been stable in our operations."
"I would recommend it to other users."
"The most crucial feature of IBM FlashSystem is compression."
"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 is the speed."
"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 features I find most valuable include its use for storage and performance."
"The most valuable feature of the solution is its upgrades, as we don't have to do much homework because of its different controllers."
"The most valuable features of IBM FlashSystem 9100 NVMe are its steady performance and usefulness in high-traffic environments."
"What I like about the product are its high availability, maximum efficiency in performance, and its ability to handle a high level of I/O operations."
 

Cons

"Adding some functions to the product would be beneficial."
"It is on the expensive side."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"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."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"The pricing needs to be more competitive."
"This solution could be improved by offering greater amounts of storage."
"We use some open-source tools for monitoring, such as Grafana and it should be bundled along with IBM FlashSystem."
"The initial setup is complex."
"The pricing could be improved, but I think it's getting better and better with each version. IBM needs to implement NAS storage again, as this is a big flaw. Dell EMC is very good at this and if you compared them based on NAS storage, Dell EMC would win right away. IBM's solution for NAS storage is very complicated. We don't have a storage box that provides file sharing from itself, we have to put software on it and go through a whole complicated process. It should be simplified."
"The customer's expectations are what they get on the cloud, they're expecting even in the on-premises deployments, going forward."
"It could be easier to implement."
"They can include Amazon file system S3 protocol in the upcoming releases. It is a cloud file system. IBM FlashSystem doesn't have this feature in the box for high-end or mid-range. We have got requests for this from customers because we need to use S3 for EDI application storage. At the beginning of every year, IBM releases firmware. When I find any bugs in the firmware during the year, I am unable to find any information from IBM regarding the bug. I need to open a ticket, and the IBM engineering team makes a patch only for me. This patch is not public. By creating a customized patch for a client, they don't really solve the issue for everyone. If multiple users have the same bug, IBM should upload the patch on the official website so that we can download it. IBM FlashSystem has a monitoring tool in the box, but it is not advanced. I need a more advanced tool for more advanced equations and monitoring. All top three storage vendors, that is, EMC, IBM, and Pure Storage, don't have a powerful monitoring tool. To monitor our box to show the statistics for I/Os and latency, I need to pay for extra software. The built-in monitoring storage is not mature enough to handle all requests and generate all reports that I need. They can include the functionality to stretch a cluster natively without using any additional boxes. In addition, there are some features that EMC has integrated with the box. These features are not available in IBM FlashSystem."
"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."
"The ZIO interface could be improved."
"The solution's compression needs to be improved, as it's not the best."
"IBM FlashSystem 9100 NVMe is currently at the end of its lifespan and will soon become obsolete in the markets."
"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 needs to be improved, as it's not the best."
"In the FlashSystem 5200, there were only four ports of 32 fiber channels for the architecture. This has been resolved in the new generation."
"The support could be better."
 

Pricing and Cost Advice

"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 licensing is on a yearly basis."
"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."
"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."
"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."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"The pricing is reasonable."
"The cost is pretty high in terms of licensing. We pay at least $100,000 USD in licensing fees for the storage."
"The price of IBM FlashSystem is a little high because you pay a premium because the solution is from IBM. We had paid for the SLA prior to using the solution."
"This solution is expensive compared to other solutions."
"The price depends of the technology that our customers need. The price can come at a lower cost but this may increase as storage is added."
"The pricing is competitive in our country."
"They've been much more aggressive in the last five, six years than they were before that."
"Overall the price of the solution is expensive and this includes the license."
"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."
"The tool's pricing is competitive."
"The product has an average cost."
"On a scale of one to ten, where one is a low price and ten is a high price, I rate the pricing an eight."
"The price of IBM FlashSystem 9100 NVMe is less than Dell. For upgrades, the Dell solutions are more expensive."
"Compared to its competitors, IBM's offering is the most cost-effective."
"The solution's price is competitive."
"There are pricing options from the mid-rand to the high-range, of which the suitability depends upon the requirements."
