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

"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."

"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."

"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."

"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."

"The Nasuni management dashboard is helpful because, on the administration side, I'm able to view all of the different filers that we have in the UK, rather than check each one of them individually."

"We use Nasuni's continuous file versioning feature and it fully protects us. With the ability to version files and have continuous recovery, it helps in terms of resiliency. If we have an incident then we would be able to easily recover from it by using the technology."

"The most valuable feature is the storage in that it only keeps the last-used data locally, while everything else is backed up to the cloud. That way, we never really have to worry about file space in each office or the replication to the other file servers for DR."

"I would recommend Nasuni because it's a proven product that has delivered results for us even in the worst-case scenario. If you're still using a traditional cloud solution like native Azure products, you are still susceptible to human error. Also, you would need to architect your backup and DR solutions, then integrate, maintain, and administer them."

"We have absolutely seen an ROI, and we are super happy with our ROI."

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."

"I would like to see Nasuni provide the ability to mirror a Nasuni appliance from one site to another. They could maybe have a standby appliance that is mirrored in a different location for disaster recovery purposes. We can recover if data and a Filer are lost because of a possible ransomware event, but even that takes time to recover. If we had the ability to have a mirrored appliance, we could flip over to that mirrored device and resume instantly rather than repopulate the local appliance with data from the snapshot history in the cloud. This is another feature that we would really like to see, if possible."

"Migration from existing systems, specifically StorSimple, could be improved, but that solution will be end-of-life by the end of the year. Also, the documentation could be more accessible."

"We forecasted that the data at my client's organization would grow by about ten percent annually, but we are migrating more data because we are bringing in some servers that had not previously been within the scope of our license. We expected it would take us two years to reach a specific amount of data, but we hit that mark in one year. The licensing cost skyrocketed, so we need to renegotiate. It puts us in a bind because we are reliant on Nasuni for our service strategy. We can't deny our customers, but we also struggle to pay for that."

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

"Some of their cross-platform features are really good, but it could always use more."

"I would like to see them improve their tools in regards to accessing data using smartphones, tablets, and iPads. I think the Nasuni app could be improved to make access to the data cleaner and more efficient."

"There is some room for improvement when it comes to monitoring. We are not using Nasuni monitoring. We are using our own monitoring through Xenos. 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."

"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."

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."

"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."

"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."

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

"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."

"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."

"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."

"Nasuni should provide small-scale licenses, like a 20 TB license. Currently, the smallest is a 30 TB license."
