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.

Solution enables exceptional performance and immense scalability for AI cluster training
I am a system integrator, and my customers are using EXAScaler as the de facto parallel file system for Google Cloud. They primarily use it for large AI cluster training EXAScaler provides amazing performance in terms of sequential read and random access, and it has a significant scalability…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"I like that the glass is always half full with CTERA file services. It keeps the data hot for users on location and then tiers off older data. If you need it, the stub is still there. You can click on it, and it's back on the device."
"CTERA stood out due to its ease of use and superior security features."
"It is a three-in-one solution for us. It is a file-sharing platform, an archiving solution, and also a backup solution."
"The CTERA Enterprise File Services Platform is a hybrid solution that supports both on-premises and cloud environments."
"The support is awesome. It is top-notch. I would rate their support a ten out of ten."
"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."
"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."
"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 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."
 

Cons

"One of the bigger things that I would like to see is additional logging. There are logs in there. They provide us with the initial logs on what is happening on our CTERA device. I appreciate that, but they do not give us any further information. I would like to have more information on the logs themselves."
"However, in some cases, they could improve performance."
"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."
"Stability-wise, we just went through one issue that they addressed. We were having cloud sync issues."
"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."
"I am looking for a process where version upgrades do not impact the customers. There is no downtime."
"The new Edge filer that they have comes with a lot more features than what we purchased. It would be better if we are able to add those extra features without having to swap out the hardware. A clear upgrade path for legacy customers would be beneficial."
"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."
"One challenge with EXAScaler is during upgrade time, as it can be problematic when upgrading node by node."
"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."
 

Pricing and Cost Advice

"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 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."
"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."
"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."
