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

"EXAScaler provides amazing performance in terms of sequential read and random access, and it has a significant scalability advantage as it is scalable to petabytes."
"The customers who use DDN EXAScaler are happy, especially when using large AI clusters for training."
"The snapshot functionality and the unified file system are definitely the most valuable features for us. The UFS allows everybody across the organization to see the exact same data at the same time, instead of having different file servers with different structures on them, and that's mission-critical. We have different branches throughout our organization that have to act on that data."
"We have less downtime and fewer trouble tickets from users who cannot access their shared files. Nasuni has reduced the friction and noise associated with file management because the devices are more reliable."
"Nasuni is tremendously easy to manage. It eliminates many of the administrative challenges associated with physical hardware storage, and you don't need to worry about any hardware failure or products reaching the end of their lives."
"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."
"I can see who is logging in on files from all over the globe. For example, if a file is locked, maybe a user in Shanghai has locked files or something, I can see that from the Management Console, then unlock the file."
"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."
"My clients are happy with Nasuni because the transmission is seamless, and it consolidates all the existing file servers into one location. Also, Nasuni has no boundaries. It's infinitely expandable. They don't have to rely on the service provider for backup and restoration. It's self-serve."
"The most valuable feature is the simplicity of the backup and restore functions."
 

Cons

"One challenge with EXAScaler is during upgrade time, as it can be problematic when upgrading node by node. Additionally, it is not multi-protocol by nature, requiring additional hardware to support various protocols like NFS or object storage."
"One challenge with EXAScaler is during upgrade time, as it can be problematic when upgrading node by node."
"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."
"We would like to have a user desktop agent to help improve the end-user experience."
"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."
"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."
"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."
"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."
"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."
 

Pricing and Cost Advice

Information not available
"The pricing is on par with everybody else, and fair."
"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."
"They could lower the cost, but it saves so much money when you go into it (by losing all the backup)."
"It's cheaper than a lot of alternatives but it's not cheap."
"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."
"Nasuni should provide small-scale licenses, like a 20 TB license. Currently, the smallest is a 30 TB license."
"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."
"The cost is based on the capacity, which is approximately $100 USD per terabyte."
