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

"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."

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

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

"The most important feature is that things are backed up automatically in AWS. We have a lot of remote sites where there is a tiny server onsite and, in a lot of cases, we really don't have to back them up because the data is automatically copied to AWS. The cloud replication is the most useful functionality for us."

"The ability to access anywhere, the ease of deployment, and the security are the most valuable features."

"The most valuable feature is the simplicity of the backup and restore functions."

"Its dependability and auditing capabilities are very important to us to be able to maintain a chain of custody of the information."

"We like Nasuni's snapshot technology. The snapshot and recovery features are the things we use most frequently. Ideally, I would recommend NFS or CFS, which gives you more benefits for clients or anyone who wants to access FTP protocol, FTP utilities, SAN, and MSS."

"I particularly like the restore process. Our financial teams make changes to spreadsheets and other files, and we've got teams using Photoshop files. They make mistakes and need to recover files, and we can do that instantly. We also have users who manage to delete folders, and we can bring them back instantly within a few seconds."

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

"It has the ability to do end-user recovery, or a user can simply contact an admin who can perform a recovery from the management console. The versioning has simplified everything. Now we don't have to worry about those components."

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 performance of the filesystem could be improved."

"There is some room for improvement when it comes to monitoring. Nasuni can provide better monitoring capabilities for us to monitor all the filers and NMC so that we don't have to use a third-party tool."

"There have been small shortcomings with support so it isn't perfect, although I don't think that any supplier I have dealt with has support that I would rate a ten out of ten."

"One area that we've recently spoken to Nasuni about is single sign-on. Another is integrating Nasuni with Azure Active Directory. In our particular case, that would allow for third-party consultants to access our Azure Active Directory environment as opposed to coming to our on-premises environment."

"When users from one office save their changes, their peers in another office can see the changes within minutes. Of course, this is an area for constant improvement and we hope that they can still reduce the amount of time it takes to replicate changes."

"The customer portal could be improved, but it has been a while since I've used it. They might already have improved it."

"The user-friendliness of its access needs improvement. When I log into the console, I see all the files that we handle globally. There are hundreds of Nasuni files that I can see on the console, but no way that I can filter them down. While this is a small thing, I need to scroll down and select the ones that I want. "Control F" doesn't work nor is there a dropdown menu that I can click on and select the ones that I want."

"Nasuni is not a stable solution."

Pricing and Cost Advice

"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."

"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."

"Its pricing can get a tad expensive. When we first took Nasuni out, we were just paying for the service. We got storage at a reduced rate. It has now changed, and they're now more of an all-in-one type of thing. It can be quite expensive, but it works out. Apart from that, licensing-wise, it's very simple."

"It is around $850 per terabyte per year. Any additional costs that you would incur are for the local caching devices that you'll need to access Nasuni. You kind of provide your own virtual machines or compute to access the data. You also pay for the object storage. So, there are three parts to it. There is the Nasuni license per terabyte. You would also pay for the actual object storage in the cloud, and then you would pay for virtual machines to access the storage."

"Our agreement is set up such that we pay annually per terabyte, and we buy a chunk of it at a time. Then if we run out of space, we go back to them and buy another chunk."

"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."

"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."

"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."

"The pricing is fair. It's an enterprise-level solution so it's not inexpensive... The cost is pretty stable year over year."

The Nasuni File Data Platform is a suite of cloud-based services designed to enhance user productivity, ensure business continuity, provide data intelligence, offer cloud options, and simplify global infrastructure. This platform and its auxiliary services are projected to replace conventional file infrastructure such as network attached storage (NAS), backup, and Disaster Recovery (DR), with an expandable cloud-scale solution. By storing file data in scalable cloud object storage from multiple providers, Nasuni positions itself as a cloud-native alternative for traditional NAS and file server infrastructure. Based in Boston, Massachusetts, USA, Nasuni serves sectors like manufacturing, construction, technology, oil and gas, financial services, and public sector worldwide, offering its services in more than 70 countries.

Reviews from Real Users

James J., IT Manager at a marketing services firm, says Nasuni’s management dashboard is helpful because he's able to view all of the different filers at once rather than check each one of them individually. He values the software’s security, reliability, good performance, helpful alerting, and responsive support.

According to a Server Engineering Services Lead at a mining and metals company, Nasuni offers good OR and DR capabilities, performs well, offers data security, and continuous file versioning helps recover from hardware failures.

The Managing Director of IT at a construction company appreciates Nasuni because it eliminates a lot of work that was previously done when managing backing up and restoring data files.
