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.

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."
"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."
"Nasuni has replaced multiple data silos and toolsets with a single, global file system."
"The most valuable feature is the simplicity of the backup and restore functions."
"The ability to access anywhere, the ease of deployment, and the security are the most valuable features."
"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."
"Overall, it has been straightforward and we're very pleased with the Nasuni system."
"My advice for anybody who is considering this product is that it works great."
"The company and its technology are solid and their solution architects and support teams are EXCELLENT!!"
"The OR and DR capabilities have been a very big help for us, reducing what used to take weeks to fix and bring back up and running for people down to a matter of minutes while keeping their experience seamless, no matter how much trouble the hardware is in at the site."
 

Cons

"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."
"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."
"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."
"One area that we've recently spoken to Nasuni about is single sign-on."
"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."
"One thing to consider is that Nasuni will have the same limitations that a traditional file storage solution will have, although that is because they are taking the place of a traditional architectural model. For example, Office 365 supports collaboration on documents such as Excel files and Word documents, but because Nasuni is a traditional file server, in that sense, it can't make use of that functionality."
"Nasuni recently implemented a health system for filers. However, it needs better visibility because it lacks data and an explanation, or reasoning as to why a particular filer may be unhealthy."
"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."
"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."
"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."
"Room for improvement would be the speed of replication of new files. I would also like to see cloud mirroring."
 

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."
"They could lower the cost, but it saves so much money when you go into it (by losing all the backup)."
"Nasuni pricing is average; it's not too high or too low."
"The pricing is on par with everybody else, and fair."
"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."
"The cost of licensing is negotiated and billed annually per terabyte."
"It's cheaper than a lot of alternatives but it's not cheap."
"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."
"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."
