Eugene Hemphill - PeerSpot reviewer
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.
MayankChauhan - PeerSpot reviewer
Delivers essential support and performance for intensive operations in real-time environments
Our infrastructure is spread across the private as well as a public cloud. Our requirement was that the IOPS latency should not be more than one millisecond. If anything goes beyond one millisecond, it's a problem for us. We wanted a system that could handle the transactions and meet our latency requirements. There are performance benefits for sure. The amount of deduplication and compression offered by Dell PowerMax is quite good, especially with databases. Dell PowerMax delivers optimum performance and reliable support, integral for handling failures and ensuring operational continuity. The performance capacity optimization and support we receive from Dell are also valuable.
Ian Rousom - PeerSpot reviewer
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

"Overall stability is very good. It is a very stable solution."
"We're able to get higher-density workloads on the same infrastructure, and we have a smaller physical footprint. The performance is excellent – during our test the bottlenecks are never on the X array, it just keeps picking up the pace to match what you need. The real-time visibility is a differentiator in my opinion."
"The most valuable feature of this solution is its ease of use."
"The high availability of the product is the most valuable feature."
"The latency is good."
"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 solution is scalable."
"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 response time, compared to XtremIO, is far better."
"Technical support has been excellent."
"The SRDF site-to-site replication for the volumes is the most important feature for us. That enables us to do site recovery and replication for our VMware infrastructure."
"Dell PowerMax NVMe's tech support is good."
"We removed the need to observe whether we ran into issues with the performance of disks or number of IOPS. Previously, our Oracle Database would throw us performance errors. Now, with PowerMax, everything runs smoothly."
"We are using the solution's application and snapshot feature."
"The high availability that other systems don't have. In other systems, there is an owner in the storage processes. But for PowerMAX, there is no owner. All the process storage is passed to all nodes without ownership. So, there is no response feature in the storage in PowerMax. In the other systems, there is a response, which is a very nice feature. No systems have such a feature."
"The upgradability and extendibility for the size of the storage unit are noteworthy."
"Previously we had migrated from Dell EMC and we had a lot of difficulties moving data around. Now, if we need to move it to any slower storage, we can move it with just a vault move within the cluster. Even moving data between clusters is extremely simple using SnapMirror. The mobility options for data in All Flash FAS have been awesome."
"The speed of data retrieval is the most valuable feature. We mostly use it for our SAP database and we are getting good IO from the hard drive."
"Storage is very reliable. You don't have to do much maintenance."
"The speed, inline deduplication, and compression are really nice. It's also just easy to manage. We use Snapshot and SnapMirror offsite, which give us some good recovery options."
"At the file level, the protocols they support are easy to use. This improves resiliency and helps us run the environment."
"The solution’s thin provisioning has allowed us to add new applications without having to purchase additional storage. We use thin provisioning for everything. We use the deduplication compression functionality for all of our NetApps. If we weren't using thin provisioning, we'd probably have two to times more storage on our floor right now than we do today."
"The most valuable features are deduplication and compression, so we get more out of our storage. The replication is also important."
"We have a comprehensive solution that could accommodate anything. We can fly it earlier and get them in the air testing and prototyping much faster than they could have with other solutions."
 

Cons

"The UI for this solution needs to be improved."
"It is on the expensive side."
"I would like to see replication and DR features in the next release of this solution."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"I'd like to see the product implement active replication for vehicles such as VMware."
"It feels more suitable for small and medium-sized businesses rather than enterprises."
"In the future, I would like to see integration with enterprise backup systems."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"Specific knowledge and expertise are required to manage it properly, which some users might find a bit challenging."
"We would like more documentation, a guide to the features of the PowerMax."
"There is some room to grow, especially with some of the installation quirks."
"With Dell PowerMax, engineering always has to be involved if you want to expand the system with a couple of disks or anything. It is quite a tedious process."
"The REST API needs improvement. We are a very big automation company, and this would be big for us."
"There are quite a few design areas where I have been trying to understand why it has been designed in certain ways. This includes redundancy at the engine level, the virtual engines, or the directors that are installed. It is also related to how the cache destaging happens, or how it's designed, and how read and write caches are designed. These are design areas where I think they can do better."
"I'd like to see the dedup and compression improve. Two to one is not very good. We should be getting something like three, four, or five to one."
"I would also like to see a real-time, graphical view of metrics. I don't know how far back in time we can look, but if we could see the performance from two months or three months back, and how it is performing now, that would be helpful."
"One of the areas that the product can improve is definitely in the user interface. We don't use it for SAN, but we've looked at using it for SAN and the SAN workflows are really problematic for my admins, and they just don't like doing SAN provisioning on that app. That really needs to change if we're going to adopt it and actually consider it to be a strong competitor versus some of the other options out there."
"The certification classes are good, but they don't cover enough of the material, and the exams only test on what is covered in class."
"NetApp AFF is a highly expensive solution, and its pricing should be reduced."
"Tech support is a place where there is room to improve the product experience. The response time when they are busy is not very good."
"One of the features that I am looking for, which is already in the works, is to be able to take my code and automatically move it to the cloud."
"The knowledge base could be improved."
"I've had a few cases where support wasn't able to answer the question or they took quite a while."
"I honestly don't have anything of note on how they can improve."
 

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."
"Our licensing fees are $500,000+ USD."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"As far as the licensing costs, everything is included in the license."
"Given its price, Pure is not the first option."
"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."
"We pay approximately $50,000 USD per year in licensing fees."
"The support cost per array is about $20,000 a year for 24/7 support."
"From reclaiming data center space which is so tightly constrained these days, it will pay for itself in a short amount of time, which is fantastic. Anything we can do to get more out of our current physical data center space helps us a ton, and PowerMax has helped enable that."
"Dell offers various pricing models, including a pay-as-you-go option where storage is provided without upfront charges, billing only for used capacity. As a 360° partner, significant discounts are available."
"Negotiate hard and consider the commercial advantages/benefits to Dell EMC for onboarding your product."
"Dell PowerMax NVMe's price is expensive."
"One area for improvement, one that everybody always comes to, is price... it's still quite expensive to purchase these big arrays... For us, the pricing doesn't make Dell EMC uncompetitive."
"The pricing for this solution is good compared to other products in the market."
"In terms of price-performance, it beat out other competitors when we were taking a look and comparing it to the market. That was one of the biggest driving points for us."
"The price is okay."
"Planning of all the lifecycle storage with NetApp AFF is part of the solution. While it is not cheap, they have introduced a new series of AFF that are more affordable, providing options for more users."
"I am able to store two times more data than what I'm purchasing, which affects the way funds are being utilized."
"Our space savings through dedupe and compression is over 50 percent, so we are saving. I think our 8080s has 20TBs. We are saving at least 10TBs and that's over 50 percent of the capacity that we're using."
"The price of the upgrading of the solution is high. I could buy a whole unit of All Flash FAS 300 with a shelf for around $285,000. Yet if I want to add one additional shelf, it'll cost me $275,000. So they want you to upgrade by replacing it. It's cheaper to buy a whole new unit than to just scale out. The upside is they last. AFF lasts us three or four years. So that's a good investment."
"With other options, you need to buy a couple of different products to achieve the same outcome."
"NetApp AFF is an expensive solution."
"Once we did get into the NetApp ecosystem, we realized that the cost effectiveness was greater than we originally thought."
"The solution is moderately priced."

NetApp vs. XtremIO
Is there another storage platform as feature rich as NetApp FAS? I think it is fair to say that NetApp FAS running Clustered Data ONTAP is a very feature rich platform – the move to the clustered version of ONTAP has brought many next-generation features including Scale-out and Non-disruptive…
