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.
Anna Sofo - PeerSpot reviewer
Since switching, our clients have reported improved performance and reduced latency
I like NetApp AFF's deduplication. The solution's AutoSupport feature is efficient and effective because customers are notified of potential issues before they experience problems with NetApp. The support is sold based on metro clusters, so they guarantee the client's business continuity. NetApp has an Active IQ app that allows you to get information on your smartphone.

Ensures streamlined management, simplified infrastructure, and efficient data handling
It has effectively managed our unstructured data, including audio and video files. We've experienced smooth operations without any complaints regarding uploading or downloading videos. While video usage isn't as frequent, we primarily utilize it for downloading videos related to specific incidents for administrators or our police department. We've encountered no issues uploading files of any kind. Transitioning from VMware to Nutanix has highlighted the overall flexibility of Nutanix's platform. Unlike VMware's three-tier system, Nutanix simplifies the learning curve by streamlining operations. The update process, in particular, has been favorable, with no critical issues encountered. The resiliency of Nutanix hasn't been thoroughly tested in our environment so far. However, I routinely check fault tolerance settings to ensure they meet our requirements. During the update process, I've observed critical errors occur as hosts restart, but Nutanix's self-healing mechanism handles these issues seamlessly. The benefit of using Nutanix is evident in several ways. Firstly, we've effectively compressed our storage while significantly expanding our overall storage pool. Previously, our service had a capacity of twenty-five terabytes, but with Nutanix, we've scaled up to a hundred and twenty terabytes physically and approximately fifty terabytes logically. This expansion has been accompanied by noticeable improvements in performance, particularly with reduced latency and IOPS well within the boundaries of our equipment. All our resources are centralized in a single location for managing and running storage: our data center. We operate three Nutanix nodes within this center, effectively managing everything from one central location. We don't have any other locations outside of our data center running a Nutanix cluster. Nutanix's capability to eliminate silos within our organization's storage infrastructure was discussed during our recent call with the engineer. Although we haven't explored this feature extensively yet, there's a forthcoming project where we anticipate leveraging it.One thing I'd appreciate is having a desktop application similar to what VMware offered. With VMware, I could download a separate client program onto my computer, allowing me to log in directly rather than accessing the host through a browser.

Quotes from Members

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

Pros

"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."
"Technical support has been helpful and responsive."
"The initial setup was extremely simple and straightforward."
"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."
"The latency is good."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"The Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."
"It has good, reliable, fast storage."
"NetApp's most valuable features are ONTAP, FabricPool, and media storage."
"The scale up version of it is the most valuable feature. You can go to 24 nodes, which is very cool."
"We can go through and do an upgrade without worrying about any issues with the process"
"Snapshots, snap clones, backups, flexibility, and agility are valuable features. I like that NetApp AFF is easy to use. We can automate everything for our backups and use cases. It's fast and simple, and provides storage to all of our VMware ESX hosts. It expands easily as well."
"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 benefits of being on AFF are the phenomenal speed at which we're able to ingest data and index it, and the IOPS."
"It provides simplicity. Previously, there was not any kind of unified structure to our multisite storage infrastructure. We now have multiple sites where we have been able to install NetApp, and through ONTAP and BlueXP, control all of them from one pane of glass, which has been very powerful for us."
"We had some customers who were running virtualization workloads on classical spinning disks. We implemented an AFF system, and they got a huge performance boost out of it because the latency of the SSDs is simply much lower. Actually, most customers benefit from the improved latency and performance from the AFF systems."
"The product's initial setup phase was simple."
"From an analytics perspective, the best aspect of Unified Storage is its locality. When you read data, you want to know that you're only reading data from the particular local storage node. It's also critical to access the data as quickly as possible from that. From a business perspective, the most important thing is ease of use. Having a combination of compute and storage makes it much easier to manage."
"Nutanix Unified Storage does a very good job of unifying our organization's block, file, and object storage. It puts it all in one place. From one platform, we can deploy S3-type buckets. We can provide iSCSI-level block storage if we need to. It does a great job with home folders and departmental shares, which is what we mostly use Nutanix Unified Storage for."
"The most valuable feature of Nutanix Unified Storage is redundancy."
"The most valuable feature is that it is highly available, solving the pain-point of delaying updates to Windows-based file servers during production hours. And then the second one would be ransomware protection and analytics. It gives you great visibility and protection on your file shares that are otherwise the most common sources of vulnerabilities."
"The most valuable feature is the unified dashboard, as it allows us to easily observe everything from a single location."
"The aspect of the product that I like the most is its simplicity."
"Nutanix's analytics provide better insights into all of our files."
 

Cons

"I would like to see some AI features that would allow arrays to intelligently identify threats or unusual behavior in the data pattern and give an alert."
"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."
"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."
"In the future, I would like to see integration with enterprise backup systems."
"It feels more suitable for small and medium-sized businesses rather than enterprises."
"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 more visibility into garbage collection and CPU performance in the GUI."
"They could add more support for file storage and different types of storage."
"The web management interface has fewer options than the on-prem console."
"When new ONTAP cloud versions come out, they need to have fewer bugs."
"The stability is good but there is room for improvement with other options."
"When you look at the competitors, they have some features available, for example on the deduplication side.​"
"We'd like to see them implement more subscription services into the base support model."
"We'd like to see improvement in the time to retrieve from the Cloud, whether it's on-prem to cloud and whether it's public or private cloud."
"Going forward, I would like more performance analytics on it, on the area itself, instead of using some other tool."
"Their customer support can be better. When we have an outage, we need to wait until it is escalated to L3 which takes a lot of time."
"Managing other storage infrastructure on Nutanix Files Storage is an area for improvement. In particular, I want to add other forms of storage from different vendors not currently in Nutanix Files Storage, to the file server, for better management."
"There are some processes, like if I like to change the data storage to another place, I have to use CLI, and I don't like it since I believe that it could have been simpler in GUI."
"Another aspect that needs improvement is continuous protection against security threats such as ransomware and potential data leakage."
"If they can add an integrated DLP feature, it would be great."
"The implementation is a little bit complex and should be made easier."
"Improving quota policies would be advantageous, particularly by offering the option to implement blocking instead of just issuing warnings."
"The GUI is not user-friendly for new users and has room for improvement."
"There should be more information. If it gets used more by more people, they will have a bigger community to share ideas. It is still kind of newer. It is not as big as Dell and other companies."
 

Pricing and Cost Advice

"Given its price, Pure is not the first option."
"The product is expensive."
"The licensing is on a yearly basis."
"Pure FlashArray X NVMe’s pricing is cheaper than other products."
"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."
"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."
"We pay approximately $50,000 USD per year in licensing fees."
"With VMware, we pay $300,000 annually."
"NetApp AFF is an expensive solution."
"The total cost, the pricing of it, has gone up quite a bit."
"Always consider whether you can afford the solution."
"The pricing is not a lot considering what you get and it bundles hardware and licensing."
"The entry point for potential customers, who are looking at coming onboard for flash systems, it may be a bit expensive. It would be good if the price comes down."
"It consolidates a lot of our storage into one or two chassis, which makes money savings in our data center."
"I would like the pricing to be cheaper."
"I do not deal with pricing, but the pricing of NetApp and Dell seems pretty close. NetApp support is cheaper than Dell support."
"The licensing model the tool has is cheaper than an HCI storage solution."
"Nutanix offers different pricing options, including Ultimate and Ultimate Pro."
"I'm happy with the cost and licensing because I don't have big volumes."
"It is quite expensive otherwise as it comes with three-tier peer underlying hardware."
"The cost of Nutanix Unified Storage can be prohibitive for some small and medium-sized businesses, making it challenging for them to adopt the product."
"The price can always be improved. As a customer, you always seek reasonable solutions within your budget, and they give us little to do a lot. My IT team always has to justify that we are choosing an optimal solution, so the price could be a little lower Maybe the prices could be a little bit lower."
"The solution's pricing is fair."
"The solution’s pricing could be cheaper."

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…
