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."

"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."

"Nasuni has helped to eliminate on-premises infrastructure. We were using about eight to 10 different types of vendors or small storage boxes for provisioning and shared access for users. We got rid of all those. That has eliminated operational overhead and footprint at our data center. We don't have to worry about any hardware or monitoring particular devices, and hundreds of devices have been decommissioned. Now, for provisioning, everything is on Nasuni. I assume this has made a big difference in costs."

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

"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."

"This solution has done a fantastic job of meeting all our needs."

"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."

"Nasuni has eased our job because we don't have to worry about the user requests for additional space anymore."

"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."

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."

"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."

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

"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."

"Its pricing can get a tad expensive."

"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."

"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."

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

Pricing and Cost Advice

Information not available

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

"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."

"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."

"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."

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

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

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

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