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.

Offers good performance and

Once, I've been in a program, but they stopped supporting protocols like HTTP, STP, and that kind of stuff. All of the DIP supports at the beginning were kind of support when it was just Python and just five storage. And it happened a few times that the customer required the STP and HTTP protocol for storage. And I was surprised I couldn't do it anymore with NetApp. So, it would be beneficial for them to support both kinds of protocols. The only little black points that I would put on top of NetApp FAS Series. There is room for improvement in deployment and configuration processes. The thing with ONTAP is that we have a lot of layers, from the raw disks to the volumes we present to servers and configure. There are quite a lot of things to configure. Probably NetApp should ease the way to install that. In NetApp products, such as ONTAP and FAS, a solid understanding of storage is still necessary to handle configurations in larger systems. It's not the same with Pure Storage or Huawei. Even someone less familiar with storage could manage it, making it more accessible.

Quotes from Members

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

Pros

"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."

"The solution is scalable."

"Technical support has been helpful and responsive."

"The initial setup was extremely simple and straightforward."

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

"I appreciate the performance."

"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."

"The database workloads are pretty fast because I frequently move data from here to there."

More Pure FlashArray X NVMe pros

"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."

"There are many valuable features of IBM FlashSystem 9100 NVMele I have found to meet my needs. Specifically, the maintenance cycle is a standout feature of this solution. The main component of the IBM FlashSystem 9100 NVMe is the maintenance of the batteries, which have a predetermined and reliable four-year life cycle. This is in stark contrast to other solutions that may use spinning disks, which can fail unexpectedly, causing unwanted downtime and maintenance. Having a predictable maintenance cycle is a significant advantage and has made this solution a preferred choice for me."

"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 high performance and high availability improved our overall processes."

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

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

"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."

More IBM FlashSystem 9100 NVMe pros

"The migration of the volume on the cluster is very useful and easy to use."

"The new FAS series is a good fit for some customers. We have good performance and capacity, even though it is full flash."

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

"It's a stable product. No issues there."

"It has a very good implementation of the Active Directory services, so implementation into a Windows network is easy."

"The solution's most valuable feature is its absolute reliability."

"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."

"The most valuable features are the NAS features and NetApp's excellent support."

More NetApp FAS Series pros

Cons

"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."

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

"The tool's portfolio is minimal. It is expensive."

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

"We've seen that when we create a POD in synchronous mode, it increases the latency."

"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 is on the expensive side."

"The UI for this solution needs to be improved."

More Pure FlashArray X NVMe cons

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

"The support could be better."

"The pricing should be more competitive."

"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."

"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."

"Deduplication and compression should be improved."

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

"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."

More IBM FlashSystem 9100 NVMe cons

"NetApp FAS Series should improve its price, which is expensive."

"The solution’s pricing is expensive."

"It could be more flexible in terms of configuration."

"NetApp could improve costs while making the solution more straightforward to use and deploy."

"There are some technical limitations, but it would be great to have in-line deduplication and in-line compression for the FAS series as well."

"Dedicated storage efficiency accelerators could improve the overall performance of the system."

"We have some experience with older equipment end-of-life. For example, when warranty support stops or updates stop – it can be frustrating. Not all clients can buy a new filer every year or two, and NetApp ending support a bit quickly can be a concern."

"NetApp FAS Series should introduce an FTP application for the broadcast and post-production market."

More NetApp FAS Series cons

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."

"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 licensing is on a yearly basis."

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

"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."

"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

"The solution's price is competitive."

"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."

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

"There are pricing options from the mid-rand to the high-range, of which the suitability depends upon the requirements."

"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."

"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."

More IBM FlashSystem 9100 NVMe pricing and cost advice

"NetApp FAS Series could be less expensive."

"The NetApp FAS series price is very competitive compared to other solutions on the market it is a good choice."

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

"The licensing cost is on yearly basis."

"The scalability is pretty good, but it's too expensive."

"The only area that could be improved is to lower prices for their All Flash FAS."

"NetApp FAS Series is a reasonably high-priced solution, partially because we select the configuration that duplicates the entire system."

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

NetApp FAS also supports multiple protocols, including NFS, SMB, iSCSI, and Fibre Channel, as well as various storage architectures, including SAN (Storage Area Network) and NAS (Network-Attached Storage).

The FAS series has multiple data protection and data management features, including snapshots, cloning, replication, and deduplication, to help secure your data and manage it more efficiently. The system integrates with other NetApp products and solutions, to create a unified data management platform. The system can be deployed on-premise, on multi-cloud environments, or hybrid.

NetApp FAS Series Benefits and Features

NetApp FAS series provides its users with several key benefits and features, including:

Scalability: NetApp FAS series is easy to scale, allowing organizations to rapidly grow their storage capacity according to demand.

Security: Protect and manage your data with various data protection and data management tools, including snapshots, cloning, replication, and deduplication.

Seamless integration: Integrate with other NetApp products and solutions to ensure a unified data management platform across on-premise, hybrid, and multi-cloud environments.

Reduced costs: Consolidation of multiple storage boxes greatly reduces the data center footprint. From a management point of view, with NetApp FAS you manage a single storage box instead of multiple storage boxes.
Compatibility: Forward and backward compatibility ensures that you don’t have to trade in existing controllers. New controllers can always integrate with previously released controllers.

Multi-protocol support: Support for multiple protocols, including NFS, SMB, iSCSI, and Fibre Channel.

High performance and availability: The solution has high input and output per second performance and ensures that critical data remains accessible in the event of a hardware failure.
Intuitive interface: The FAS series has a user-friendly interface and management dashboard, making it easy to manage your storage systems. With unified management, you can quickly run a single protocol on your entire system
Data cloning and replication: Easily clone databases of any size. Clones occupy a very, very small footprint on the storage until they are severed from the main database. Replications carried out by the system are fast and require very little bandwidth.

Reviews from Real Users

NetApp FAS Series stands out among its competitors for a number of reasons. Several major ones are its speed, reliability, and a wide variety of features.

Adriano S., IT project and infrastructure service manager, writes, “The replication feature is noteworthy because it's faster than most and it uses little bandwidth. Then there's the friendly interface that the equipment offers. With this interface, it is very easy to manage.”

Temitope O., a NetApp product manager at Hiperdist Ltd, says, “I like the unified management feature because sometimes you end up running a single protocol on the entire system. You rather have a system for a particular protocol and another system for other protocols, especially in a big environment like mine.”
