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

"It has snapshot capabilities. We take advantage of those."
"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."
"With Nasuni, the simplicity of management is light-years ahead of our previous processes because the old backup and recovery was so slow, and we had to keep growing the SAN as the business grew."
"We have absolutely seen an ROI, and we are super happy with our ROI."
"Nasuni offers us a single platform with a 360-degree view of our file data, which is definitely important to us. It simplifies IT operations tremendously. Because it is taking continuous snapshots, it eliminates a lot of work that was done previously when trying to manage backing up and restoring data files."
"The system has so far been doing an awesome job and working as advertised."
"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."
"The most valuable feature is that we have redundancy in our data. It's nice to know that it is cached both locally on the filters, as well as stored on that cloud."
"With Nasuni Management Console (NMC), we get a single, centralized view of our entire internal structure and data center structure. This is very important because this caters to remote locations. One of the main care center teams is dependent on this solution. As it is directly connected to customers for the calls that they receive and troubleshoot, they can then help customers out in case they are not able to place an order."
"Another helpful feature, in addition to restoring a file that was deleted within 24 to 48 hours, is that we have the ability to restore a file or a folder that was deleted, going all the way back to the inception of that file or folder. That means we actually have unlimited backups to the inception point of data with Nasuni."
 

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."
"It would be helpful to have more built-in analytics tools to compare the storage costs between the various cloud providers. I would also like some graphing capabilities. We had a tool called Grafana that we used for graphing. I think some more visual analytics like that would be nice."
"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."
"One area that we've recently spoken to Nasuni about is single sign-on."
"I would say that they need to make their technical support quicker."
"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."
"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."
"There are some issues with multiple users accessing the same file simultaneously. There would be times when the global file would lock when several people tried to access it, so that could be optimized more."
"When we have to rebuild a filer or put a new one at a site, one of the things that I would like to be able to do is just repoint the data from Azure to it. As it is now, you need to copy it using a method like Robocopy."
 

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."
"The cost of licensing is negotiated and billed annually per terabyte."
"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 pricing is on par with everybody else, and fair."
"Nasuni should provide small-scale licenses, like a 20 TB license. Currently, the smallest is a 30 TB license."
"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."
"There are cheaper forms of storage, but Nasuni is fairly priced for the functionality it offers. I can get basic file shares provisioned in Azure and pay for the storage and the CPU. The overall cost would be much less than Nasuni, but I would need to build the management console and encryption process, so it would cost a lot to develop that kind of functionality."
"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."
"It's cheaper than a lot of alternatives but it's not cheap."
