Along with offering competitive prices, the solution can be used by small, medium, and large businesses

While guaranteeing the strictness of the file system, there is a lot of performance involved. The performance is not as good as I expected. It's not the functionality here but the performance level. It won't be a problem if it's twice as fast. Even though its stability has room for improvement, I would recommend it to my bigger customers. The only problem is the current performance of the individual nodes. As a sale-out solution with integrated load-balancing functions, performance is in principle not a problem at all. Capacity and performance are linearly scalable over the number of nodes in the cluster. An increase in the performance of the individual nodes in future releases would be desirable.

Cloud data management that achieves cost efficiency with advanced data protection features

I am currently using Nasuni for seismic data. We have a huge data size, and we want to reduce costs. Nasuni acts as a caching solution, so we put some data into the cache, and the rest goes to the blob, which helps us save on costs. We use it for applications like Petrol and Tech Log, where 3D…

Quotes from Members

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

Pros

"Scalability-wise, I rate the solution a ten out of ten."

"It has snapshot capabilities. We take advantage of those."

"We switched over to it because it is an integrated solution that includes DataProtect and the platform, has other use cases for enterprise search, and can also do things like antivirus."

"With a shift to more remote work during this past year, we deployed a new instance of Nasuni in Azure, which allowed us to be more flexible and support remote work better, something we wouldn't have been able to do with legacy file storage."

"The solution gives us a breakdown and summary of every resource and each volume within every resource. It tells us the code within a given volume, so I can go in there and look at the size of the files that are stored there. Nasuni gives me the big picture and allows me to connect things like Power BI to any endpoint. I can take that tabular information from Nasuni and look at it in a graph."

"Nasuni is helping us replace multiple data silos and toolsets with a single global file system."

"With Nasuni, we have been able to replace multiple data silos and toolsets with a single global file system, which is important to us because we have been able to consolidate several different products and solutions."

"Snapshot backup is most valuable. It's quick and easy to use. It's controlled only by an administrator, which is very good. It takes 10 seconds to back up a spreadsheet of three or four megabytes."

"Nasuni gives us a single platform with a 360-degree view of our data, which is important so that we know the size of our estate and the amount of data that we hold."

"Using this solution has helped us to reduce the time it takes to recover data in the event of a disaster, lower our cost of operations, reduce our workload, and our savings through using Nasuni is approximately 35%."

"This solution has done a fantastic job of meeting all our needs."

More Nasuni pros

Cons

"Its read performance can be improved. It is just slow in comparison to other file systems, but a lot of it also has to do with the fact that they have a limited number of spindles under each node."

"The only problem is the current performance of the individual nodes. As a sale-out solution with integrated load-balancing functions, performance is in principle not a problem at all. Capacity and performance are linearly scalable over the number of nodes in the cluster. An increase in the performance of the individual nodes in future releases would be desirable."

"The speed at which new files are created is something that could be improved. For example, if you create a new file in another country, I won't see it for between 10 and 15 minutes."

"We can recover if data and a Filer are lost because of a possible ransomware event, but even that takes time to recover."

"I would like to see Nasuni create a Dropbox or Box alternative. One of the things that people like about those tools is that they are very easy to implement. They look just like a file server. With Nasuni, you have to be online to get your file storage. With Dropbox, there is a thing running on your PC that downloads the files to it when you need them, i.e., an agent."

"It is difficult to configure Nasuni. Adding a filer is an easy task, but deciding where to add them, how many to add, and what size to add takes a lot of time. I have to analyze my existing storage to understand how many users are going to access which folders. I have to design the Nasuni architecture accordingly."

"The privilege settings need to be more granular, and alerts are an excellent example. If a user doesn't have access to them, they can't see them and access information such as what they may have done wrong, what's there, and when the last sync happened. However, the ability to view alerts also comes with permission to delete them, which is not good, so we need more customization options here."

"As administrators, we are used to having control equal to managing an on-prem device. In terms of log analysis and other things we want to do, Nasuni has some limitations limitation on what you do on the Nasuni. Nasuni could add some features to the GUI that make administration a little easier. It's tough when I have to move from one filter to another because there is no way to search it. We have to scroll up and down to find the name of it."

"Its interface design or the graphic user interface design can be slightly tweaked in some areas."

"We've had some organizational changes that Nasuni has not been able to keep up with, mainly from a data or file system perspective. Moving a filer from one management console has been a challenge. It lacks the flexibility to move files in and out of the management console. We have six management consoles now, and we're constantly telling Nasuni, "Hey, please allow us to move a filer from management console A to B." They can't do that."

Pricing and Cost Advice

"When it comes to pricing, I know the prices because I am also running tenders for customers where I am not offering other solutions. Hence, the prices are pretty competitive."

"I won't talk about specific numbers, but it is a little hard to compare it to other products out there because there is nobody out there that does exactly what they do. If you are just comparing it to another NAS box, it is probably going to look higher, but that's an unfair comparison because it does things that a NAS box can't do."

"It's cheaper than a lot of alternatives but it's not cheap."

"It has a license fee as well as hardware costs, which we would incur if we want to use Nasuni Cloud Storage Gateway for upgrades."

"I would not say it is economically priced, but it is affordable. If you can afford to pay for it, it is worth the money, but it is definitely not overpriced. It is priced about where it needs to be in the market. We were satisfied with the way they did their licensing and how they handled it. I believe they actually license by data size. It is based on how much data is being held on the machine and replicated, and that's completely understandable. So, for us, their pricing was as expected and affordable."

"The cost is based on the capacity, which is approximately $100 USD per terabyte."

"The cost of licensing is negotiated and billed annually per terabyte."

"There are annual costs that we pay for maintaining all of the snapshot history in the cloud. That is the primary cost that we pay. We occasionally buy newer Nasuni appliances or deploy them to new offices when the need occurs. That capital equipment expenses is less than the cost of buying new file storage systems. For the most part, you are trading a CapEx cost of storage equipment for an OpEx cost for management of all the snapshot data in the cloud."

"With this solution, the license renewal is pretty swift. With the virtual appliance, you just need to take care of the OS versions and patches. In a way, we don't have to struggle much with renewals because the only thing that we need to take care of are the licenses. We renew it every three years. This aspect goes with infrastructural costs because it doesn't cost us too much to maintain the solution."

"Its price is fair and reasonable. I don't have anything negative about its pricing and licensing. For us, there is also the cost of monitoring. We are monitoring through Xenos and not through Nasuni. That is another cost for us from the monitoring perspective, but as far as Nasuni goes, we don't have any other cost apart from the licensing fee."
