Sales Manager at Multicomputos PR

Helps to save money and resources with the data compression feature

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. One way to improve the product is to add an operational assistant that doesn't depend on VMware. It could also establish more alliances with other operational systems.

Owner at RTX

Flexible with great support and high-speed multi-protocol storage

Keystone offers flexible consumption models that go beyond just how much capacity at such and such a speed, et cetera. We don't always know what the profile of that data will be. However, if we can quickly agree on terms that meet our needs and make NetApp still reasonably profitable, we can confidently deploy, see how things go and adjust. That kind of service delivery model, that customer service model has sped things up and made contract negotiations much easier. It frankly made the owners of the system more confident. We've experienced faster time to market. It's hard for us to find and retain infrastructure staff. We're in a business where the firm fixed price contract reigns supreme, and so we can't always just offer someone more money. However, if they can dedicate their time to learning one company's portfolio and learning it really well, but be useful in a bunch of different places, they will do well. We've seen that in a lot of different places. We've been able to hire younger people and retain them, moving them from program to program based on their understanding of the solution its skill set, and its portability. It's been useful for high-speed multi-protocol storage in places with ever-increasing density. We have limits on how much power and cooling and rack space we have, and yet they've delivered every time. We needed a storage company that had mastery of multi-protocol, and this solution stands out. They especially stand out as a secure provider. We require solutions that we can run ourselves, that we can air gap since so much of what we do is either classified or very sensitive or cannot live in a public ecosystem. For us, the issue consuming AI has been the trust of the models given to us by third parties. We can't necessarily trust their provenance, what fed them, what originally trained them, or what gave them their worldview, for lack of a better term. We can't simply just trust that at face value since we know nothing about where it came from or what inferences it might make. We must assume that some AI inferences were made deliberately to damage or hurt national security systems. So the models that we start with tend to be very, very primitive, crude, and not well trained, so we have to train them much longer and not always with the availability of cloud that has inexhaustible capacity. A partner who understands this and provides consistency at all scales is very important.

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."

"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."

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

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

"The latency is good."

"The high availability of the product is the most valuable feature."

More Pure FlashArray X NVMe pros

"IBM FlashSystem is the best solution for storage virtualization."

"The valuable features for us are the extra add-ons, such as the FIM provisioning, the compression, the disaster recovery capabilities, and the storage pooling functions."

"Flash disk with Easy Tier option"

"The feature I find most valuable, is the deduplication, because the nature of the data that we are using in our current environment, has a lot of replicated data."

"It's very easy to manage."

"The most crucial feature of IBM FlashSystem is compression."

"The solution is scalable and has varying degrees of scalability."

"The speed and the ease of installation are the most valuable features."

More IBM FlashSystem pros

"The performance of NetApp AFF allows our developers and researches to run models and their tests within a single workday instead of spreading out across multiple workdays."

"I think that the DR applications are the most valuable, including Snapshots and SnapMirror."

"I like NetApp AFF's deduplication."

"We recently started using the volume encryption feature, which is helpful because there are some federal projects that require data at rest to be encrypted."

"It scales well, probably more so than the FAS. Because of the storage density with the SSDs, we can't buy enough SSDs to max one out."

"The newest version of ONTAP has a bit of a learning curve because you need to learn where things are to find them. It is not impossible, but when you are accustomed to the older version of ONTAP, it just takes a bit getting used to it, but it is about the same as before."

"The most important features are the IOPS and the ease of the ONTAP manageability."

"It is a stable solution."

More NetApp AFF pros

Cons

"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."

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

"We would like to see VNC integration or be able to use Pure Storage with VNC."

"The software layer has to improve."

"Managing data isn't difficult for me. The performance is usually perfect, but we sometimes have capacity problems."

"They could add more support for file storage and different types of storage."

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

"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."

More Pure FlashArray X NVMe cons

"We use some open-source tools for monitoring, such as Grafana and it should be bundled along with IBM FlashSystem."

"The security features can be improved such that the encryption does not affect performance in any way."

"Sometimes the performance is effective but it gets resolved in the process."

"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."

"In the next release having the next level of high-speed performance would be great."

"Our model does not support compression or deduplication."

"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."

"IBM could do more marketing and improve brand awareness. I had never heard of this product until a colleague told me about it. FlashSystem could add a few features, but it would probably increase the price. For example, Pure Storage offers instant snapshotting and partitioning. That would be nice to have, but I think the cost would go up."

More IBM FlashSystem cons

"The product has size limitations on fax volume. They have increased from 100 to 300, which is still less than other vendors. Or flex groups are not supported."

"I want an interface through ONTAP that look more like what it does for the E-Series with Santricity."

"I would like it to be an IP as our network is mainly IP-based."

"NetApp AFF could improve SAN storage because it feels as if it was not put together at the beginning, it functions as an afterthought. Additionally, the cloud features could be more mature."

"I would like to see a little more flexibility in customizing some of the SnapMirror stuff. We have been having a little trouble and, in the first round with tech support, they say, "Well, this is how we do it." It's not exactly throttled but it's limited in the number of connections it makes. We would like to be able to tweak that, to increase it a little bit, because we don't have half a dozen large areas that we are protecting, we have more like 40 or 50 areas. They run into each other a little bit and I don't want to spend time on them."

"Our backup system, Commvault, has an amazing capacity to do compression and deduplication better than NetApp AFF by itself. If they can spend some time improving deduplication and compression, it would be great because it has been proven that some commercial features can do it."

"Tech support is great with NetApp if you can get past Tier 1. A lot of times when you open a new case or do a direct dial-in with an issue, like with any support, you will definitely reach a Tier 1 level that is not particularly helpful until you get escalated to an expert."

"A graphical user interface displaying efficiency metrics, such as compression and deduplication rates, would be a great addition."

More NetApp AFF cons

Pricing and Cost Advice

"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."

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

"The support cost per array is about $20,000 a year for 24/7 support."

"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 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."

"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."

"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 product is expensive."

More Pure FlashArray X NVMe pricing and cost advice

"You purchase it as a bundle and the price is comparable."

"There are no licensing fees, it is a one-time purchase of the IBM FlashSystem."

"Our customers would like IMB FlashSystem to be less expensive."

"We have no issues with the price as it is very competitive."

"My customers got the IBM FlashSystem bundle offer. It was a one-time purchase for three years of service. The price would depend on the storage size and could reach between $25,000 to $55,000."

"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."

"The integration is already included in the license cost of IBM FlashSystem. The integration is very easy. You get the IBM storage core with all software, firmware, and upgrades. EMC provides the features in the box, but they are not free for customers. There is a licensing cost for features. We have yearly licensing, but IBM has also provided a new option where you pay as you go. They provide a big box, and I pay, for example, for 10 terabytes. If I exceed 10 terabytes, IBM will charge for the new storage after 10 terabytes. It is a good opportunity in the market for using the storage as a cloud and paying as you go."

"The price of IBM FlashSystem is reasonable."

More IBM FlashSystem pricing and cost advice

"The solution is moderately priced."

"It depends on how you look at things, but they are in a higher price range."

"We have used the solution’s thin provisioning to add new applications without having to purchase additional storage. We use thin provisioning on all of our flash arrays at this point. It gives us the choice to be able to overprovision and take advantage of compression, compaction, and thin provisioning all at the same time. We can get more out of the purchases that we make."

"I am able to store two times more data than what I'm purchasing, which affects the way funds are being utilized."

"Disk level encryption is already in the solution, but it is very costly. Its pricing should come down."

"The pricing is pretty reasonable for what we get. But if you have to buy any more disk space, it can be quite expensive."

"From an application standpoint, we have seen a lot of return investment on the speeds and responsiveness of the actual storage."

"Other vendors may come in at a cheaper price point, but you will pay in the end with management costs and downtime."

Reviews from Real Users

NetApp AFF stands out among its competitors for a number of reasons. Two major ones are its high performance and simplicity. PeerSpot users take note of the advantages of these features in their reviews:

PeerSpot user and Storage Administrator, Daniel Rúnar Friðþjófsson, comments “AFF has helped to simplify our infrastructure, while still getting very high performance for our business-critical applications. Having all these things working well on one solution is really good. We run this as the backbone for both Hyper-V and VMware as well as an archive location for Rubrik. So, it is great having one solution that can do it all.

Because of the ease of it all, you have a highly tunable, high-performance storage system that alleviates a lot of problems. With its ease of management, you can quickly get your work done and go onto the next thing on your list.”

Additionally, Mohan Reddy, Sr. Technology Architect at a Pharma/Biotech company comments on how “NetApp's ONTAP data management software has also made tasks simpler for us. There's no question about that. It has helped us run operations very quickly, saving us a lot of time. Before ONTAP, we used to spend a long time doing regular operations, but with the latest version of the tool, our day-to-day operations are much quicker and easier.”
