MuhammadAzhar Khan - PeerSpot reviewer
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.
Igal Muginstein - PeerSpot reviewer
Offers flexibility, fast performance, and ransomware protection
The platform is releasing new features at a fast pace, which sometimes leads to version updates every three to six months. Although updates are generally not complex, it is challenging to stop the production environment during these updates, even if the downtime is just a few minutes. This is a common challenge across all NAS providers. From my perspective, the most important area for improvement is developing a method to perform updates without affecting customer production environments. Additionally, there are some cache size limitations that might become problematic for future use cases, though they don’t impact current applications. Collaboration for NFS and SMB protocols could also be enhanced. Although this issue isn't specific to CTERA, it is something we are working on together to improve. The quality of the versions has improved, but occasional issues still arise. All solutions face this challenge, but we hope to see a continued reduction in the number of bugs. That said, we haven't had any major production problems in the last four years, and we appreciate how responsive CTERA is to our issues. We engage in brainstorming sessions together, and we value this relationship.

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."
"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."
"On a scale of one to ten, I would rate Amazon FSx a ten."
"We used it for disaster recovery perspective behind a number of resources, like batch services and RDS."
"CTERA's instantaneous and redundant file replication, available across multiple geographical locations, ensures easy and user-friendly recovery."
"The CTERA Enterprise File Services Platform is a hybrid solution that supports both on-premises and cloud environments."
"CTERA is a very scalable product, allowing us to grow."
"The solution provides substantial flexibility, allowing the separation of workloads across various hardware platforms without vendor lock-in. This flexibility makes it adaptable to future infrastructure changes."
"The features I find most valuable are in the gateways themselves. They have done a great job over the years of providing insight into what is happening with our products, with the batches that come through that are scanned. I enjoy that part of it, and it is fairly easy to use from our standpoint once we get to know the product."
"CTERA has been particularly capable of keeping all of our workstations backed up. That became a critical feature for us during the pandemic when computers were rarely in the office. Everybody went off-site with their computers, and we were accustomed to working with a centralized storage infrastructure where people would come to the office and connect to the server to use, create, and modify files. Everything was done directly to that server."
"The support is awesome. It is top-notch. I would rate their support a ten out of ten."
"Our main reason for going for this solution was the uncontrollable growth of file data. It was unsustainable on our previous platform or technology. We needed something scalable like CTERA, so it was the scalability that we required."
 

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 area for improvement is the migration tool, which at times does not work as designed, necessitating the use of alternative solutions like Robocopy."
"One suggested improvement for the CTERA Enterprise File Services Platform is the ability to distribute data across multiple active backend storage nodes rather than the current limitation of a single active node."
"The web portal that our users access to view data and backups could be optimized. CTERA could apply some of the improvements made to their administrative interface on the user side. The administrators are a much smaller group of people than the users, so it would be helpful if they targeted user experience resources to them."
"They fixed all the requirements that we had in the beginning. The beginning was a little bit rough, but we tuned it nicely. However, in some cases, they could improve performance."
"It has a learning curve."
"More monitoring from the platform would be good. There is some monitoring, but it is paid. It is a chargeable service. It would be good for that to be included in the base."
"It would help to have a global single-pane-of-glass view of all my CTERA devices. We have different regions, and we must log in to each portal to see what's happening with those. It would be nice to have a single portal to see the health of the devices, versions, and firmware upgrades. Sometimes, we want to dive into something more complex, like investigating why CTERA storage usage grew from 2 terabytes to 4 terabytes in a week. That's a little challenging. It's something we would like to see on the road map."
"However, in some cases, they could improve performance."
 

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."
"CTERA's pricing model is competitive compared to other companies that achieve the same thing. Their closest rival is Nasuni, and CTERA is significantly more affordable than Nasuni."
"It is hard to compare the costs if we want to retain the same model of a separate high-performance storage or certain things, but it is one of the cheapest solutions available in Israel."
"I find the pricing reasonable. They offered us deals that helped us. Especially with the upgrade to a bigger unit last year, they were helpful with the deal."
"I am not directly involved in the pricing aspects, but I understand that CTERA's pricing is competitive and within industry standards."
"CTERA's pricing seems to be on par with some of the other players, such as Nasuni and Azure. They all have benefits, but CTERA is competitive for its features."
"So far, pricing seems to be fine."
"It is fairly priced. I am not too involved in the pricing of what we used to pay, but it would have reduced the cost of ownership. I cannot give a figure, but the EMC solution was very expensive compared to CTERA."
