Shared storage capabilities provide enterprise value with good reliability

Amazon FSx is more costly compared to other storage solutions like EBS or EFS. The auto-scaling feature should be improved, as it currently includes downtime. I need to manually increase the storage, which is not ideal. Integrating FSx with Windows Server is challenging; it's a long process involving Active Directory (AD) setup and synchronization.

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 shared storage capability is highly valuable."

"On a scale of one to ten, I would rate Amazon FSx a ten."

"FSx operates as an independent service, not tied to any server, which eliminates dependencies between applications for storage."

"I rate the stability of Amazon FSx ten out of ten."

"We used it for disaster recovery perspective behind a number of resources, like batch services and RDS."

"Nasuni Management Console (NMC) is super valuable, and both physical and virtual filers are also valuable. NMC is the one-stop place for all our filers, both virtual and physical filers. They are definitely doing a great job in housing all our documents and surveillance videos."

"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."

"With Nasuni Management Console (NMC), we get a single, centralized view of our entire internal structure and data center structure. This is very important because this caters to remote locations. One of the main care center teams is dependent on this solution. As it is directly connected to customers for the calls that they receive and troubleshoot, they can then help customers out in case they are not able to place an order."

"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."

"The solution gives us a breakdown and summary of every resource and each volume within every resource. It tells us the code within a given volume, so I can go in there and look at the size of the files that are stored there. Nasuni gives me the big picture and allows me to connect things like Power BI to any endpoint. I can take that tabular information from Nasuni and look at it in a graph."

"With a shift to more remote work during this past year, we deployed a new instance of Nasuni in Azure, which allowed us to be more flexible and support remote work better, something we wouldn't have been able to do with legacy file storage."

"Nasuni is helping us replace multiple data silos and toolsets with a single global file system."

"Nasuni has helped decrease capital costs by 66% since we don’t need to buy as much excess capacity."

More Nasuni pros

Cons

"A direct FTP feature would be beneficial instead of relying on transmission services."

"I've been facing a challenge when doing a failover from FSx side. AWS console does not refresh within a half hour."

"Amazon FSx is more costly compared to other storage solutions like EBS or EFS."

"From my experience, there are areas in Amazon FSx where more performance is needed, as they will be looking for higher IOPS."

"One thing to consider is that Nasuni will have the same limitations that a traditional file storage solution will have, although that is because they are taking the place of a traditional architectural model. For example, Office 365 supports collaboration on documents such as Excel files and Word documents, but because Nasuni is a traditional file server, in that sense, it can't make use of that functionality."

"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."

"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 performance of the filesystem could be improved."

"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."

"Some applications may not be suited for the Nasuni environment. You may need something with better performance. Otherwise, if you want to run daily operations or some file system, it's a good bet."

"Its pricing can get a tad expensive."

"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."

More Nasuni cons

Pricing and Cost Advice

"The lowest price I have paid is $370 or $380 per month, while the highest can exceed $3,000 per month."

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

"It has a license fee as well as hardware costs, which we would incur if we want to use Nasuni Cloud Storage Gateway for upgrades."

"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."

"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."

"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."

"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."

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

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