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

"The customers who use DDN EXAScaler are happy, especially when using large AI clusters for training."

"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."

"A big advantage is having the data exist in the cloud, which has certainly relieved a lot of pressure from our IT department in regards to having a backup as well as preventing some ransomware in all of our offices."

"The most valuable feature is disaster recovery. We can fully recover a site in two hours."

"Nasuni reduced our overall storage footprint at our sites by 70 to 80 percent."

"The most valuable feature is the simplicity of the backup and restore functions."

"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."

"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."

"With Nasuni, we have been able to replace multiple data silos and toolsets with a single global file system, which is important to us because we have been able to consolidate several different products and solutions."

More Nasuni pros

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."

"The only thing that I'd like to see is more support for platforms like OneDrive or Box.com."

"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."

"Its pricing can get a tad expensive."

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

"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."

"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."

"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."

"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."

Pricing and Cost Advice

Information not available

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

"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."

"The pricing is on par with everybody else, and fair."

"Nasuni pricing is average; it's not too high or too low."

"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."

"It's cheaper than a lot of alternatives but it's not cheap."

"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."

"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."
