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."

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

"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 features I find most valuable in Nasuni are the unlimited snapshots, antivirus capabilities, auditing, and ransomware protection."

"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."

"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."

"The nice thing about Nasuni storage is that it is immutable. This means the data is only written once. So, you never modify the files. When you write a file out to the storage, it doesn't modify it when you change it. The technology knows how to figure out what the difference is between the original file write and what the changes are. Therefore, it only saves the changes."

"We've used it to provide file source capacity for VDI environments. The security of it is important and the fact that it's object storage, it's immutable and that it can't be held for ransom. It's a lot smoother than our previous processes that weren't Nasuni-based. A lot of it is done automatically just by the system being in place."

"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."

More Nasuni pros

Cons

"One challenge with EXAScaler is during upgrade time, as it can be problematic when upgrading node by node."

"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."

"Nasuni provides enough reporting to see what's happening. You can see the number of shares, total volume, issues, conflicts, etc., but it doesn't provide much visibility from a content perspective. For example, it doesn't tell you the data age. When you're trying to sort and filter information, the data creation date is a critical factor. Nasuni doesn't give you that. You can't get a count of all the file types, like the number of PDFs, Word docs, and PPT files."

"I would like to see improvement in the training Nasuni provides. Compared to some of the other vendors out there, like Microsoft, where you can find how-to videos, Nasuni only has a lot of PDF documents that you have to go hunting for. It's workable, it certainly isn't a problem, but video walkthroughs would always be helpful."

"Its interface design or the graphic user interface design can be slightly tweaked in some areas. Some built-in setup wizards would be very beneficial. Rather than having to go in and configure it by hand, there should be more setup wizards for onboarding new data shares and getting it set up the way you want. I don't know if these are on their roadmap, but I sat down and talked to them about some of the work concerns, some of the things that we liked, and some of the things that we didn't like. They are probably working on that."

"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."

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

"The performance of the filesystem could be improved."

"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."

"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

"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."

"They could lower the cost, but it saves so much money when you go into it (by losing all the backup)."

"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."

"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."

"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."

"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 is based on the capacity, which is approximately $100 USD per terabyte."

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

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.
