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

"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."
"The shared storage capability is highly valuable."
"We used it for disaster recovery perspective behind a number of resources, like batch services and RDS."
"My advice for anybody who is considering this product is that it works great."
"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."
"The Nasuni management dashboard is helpful because, on the administration side, I'm able to view all of the different filers that we have in the UK, rather than check each one of them individually."
"We use Nasuni's continuous file versioning feature and it fully protects us. With the ability to version files and have continuous recovery, it helps in terms of resiliency. If we have an incident then we would be able to easily recover from it by using the technology."
"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."
"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."
"This solution has done a fantastic job of meeting all our needs."
"Nasuni has helped to replace multiple data silos with a single global file system, providing a single platform with a 360-degree view of our data so we can secure it properly, ensure resiliency, and maintain the visibility required for strict regulations like GDPR."
 

Cons

"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."
"A direct FTP feature would be beneficial instead of relying on transmission services."
"From my experience, there are areas in Amazon FSx where more performance is needed, as they will be looking for higher IOPS."
"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."
"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."
"Nasuni is not a stable solution."
"When we have to rebuild a filer or put a new one at a site, one of the things that I would like to be able to do is just repoint the data from Azure to it. As it is now, you need to copy it using a method like Robocopy."
"Some of their cross-platform features are really good, but it could always use more."
"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."
"Part of the problem seems to be that Nasuni currently is not set up to do 24/7 support; they said that they were going to do that, so that was a little disappointing."
"Its pricing can get a tad expensive."
 

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."
"It's cheaper than a lot of alternatives but it's not cheap."
"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."
"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."
"The pricing is on par with everybody else, and fair."
"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."
"The cost is based on the capacity, which is approximately $100 USD per terabyte."
"Nasuni pricing is average; it's not too high or too low."
