From my experience, there are areas in Amazon FSx where more performance is needed, as they will be looking for higher IOPS. Sometimes we go with Weka or other solutions due to this need, so it should have more IO capacity when there is a demand. More performance is needed specifically in the IO area.

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."
"I rate the stability of Amazon FSx ten out of ten."
"FSx operates as an independent service, not tied to any server, which eliminates dependencies between applications for storage."
"We used it for disaster recovery perspective behind a number of resources, like batch services and RDS."
"I can see who is logging in on files from all over the globe. For example, if a file is locked, maybe a user in Shanghai has locked files or something, I can see that from the Management Console, then unlock the file."
"Nasuni gives us a single platform with a 360-degree view of our file data, which is very important to us. We have everything that we need to look at in a single pane of glass."
"We have one platform to manage all of our data, to see it and to quickly access it, and that is huge."
"Nasuni is tremendously easy to manage. It eliminates many of the administrative challenges associated with physical hardware storage, and you don't need to worry about any hardware failure or products reaching the end of their lives."
"The company and its technology are solid and their solution architects and support teams are EXCELLENT!!"
"The most valuable feature is the simplicity of the backup and restore functions."
"Its dependability and auditing capabilities are very important to us to be able to maintain a chain of custody of the information."
"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."
 

Cons

"Amazon FSx is more costly compared to other storage solutions like EBS or EFS."
"Amazon FSx is more costly compared to other storage solutions like EBS or EFS."
"I've been facing a challenge when doing a failover from FSx side. AWS console does not refresh within a half hour."
"From my experience, there are areas in Amazon FSx where more performance is needed, as they will be looking for higher IOPS."
"A direct FTP feature would be beneficial instead of relying on transmission services."
"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."
"We forecasted that the data at my client's organization would grow by about ten percent annually, but we are migrating more data because we are bringing in some servers that had not previously been within the scope of our license. We expected it would take us two years to reach a specific amount of data, but we hit that mark in one year. The licensing cost skyrocketed, so we need to renegotiate. It puts us in a bind because we are reliant on Nasuni for our service strategy. We can't deny our customers, but we also struggle to pay for that."
"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."
"When we first set up our bandwidth limiting, we had a few problems when it came to managing it."
"The only issue we face with Nasuni is from the performance perspective. Sometimes, when we deploy a Nasuni device, it doesn't meet our requirements. It's a capacity-planning issue."
"Room for improvement would be the speed of replication of new files. I would also like to see cloud mirroring."
"The speed at which new files are created is something that could be improved. For example, if you create a new file in another country, I won't see it for between 10 and 15 minutes."
"One area that we've recently spoken to Nasuni about is single sign-on."
 

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."
"Nasuni should provide small-scale licenses, like a 20 TB license. Currently, the smallest is a 30 TB license."
"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."
"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 pricing is fair. It's an enterprise-level solution so it's not inexpensive... The cost is pretty stable year over year."
"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."
"The cost is based on the capacity, which is approximately $100 USD per terabyte."
"They could lower the cost, but it saves so much money when you go into it (by losing all the backup)."
"The pricing is on par with everybody else, and fair."
