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.

Supports global file recovery and rapid data versioning across 80 nodes
When we implemented CTERA Enterprise File Services Platform early on, and we've been on the platform for three years, we have three different cloud portals. We have an EU portal, we have an Americas portal, and we have an APAC portal. It would be nice if we could combine that into one portal just for that global single pane of glass look. We've talked with them about that and they say it's challenging just because of some of the structure, but that would be something nice if we could get that. I integrated with Varonis, and because CTERA Enterprise File Services Platform didn't have initially a working relationship with that vendor, it would have been nice had that pre-existed us saying we need this. But that wasn't totally CTERA's fault. There was a lot of challenge working with the vendor to build out that interface. A single pane of glass for CTERA Enterprise File Services Platform would be beneficial. Everything else works fairly well. We've never had a point where we couldn't get to something that caused us to have a serious outage, and that to me is the mark of a good software package. It's never really caused us serious issues. We have our issues, that's true, and every software package does. However, we've always been able to meet the needs of the business, and we drive hard on security, stability, and scalability. From the scalability standpoint, that's one of the most important things to us. We're on their capacity-based licensing, so if I need to ramp up another CTERA Enterprise File Services Platform NAS, if we have an M&A, I can easily and quickly spin up another NAS and start doing that data transition fairly quickly. The biggest maintenance issue with CTERA Enterprise File Services Platform is firmware upgrades. We've done a lot of transition from hardware solution to virtualized infrastructure in order to minimize that hardware lifecycle portion of it. We have to upgrade the firmware and sometimes that can be challenging in the nature of business of our size with 80 CTERA Enterprise File Services Platform nodes around the globe. The issue we've had with CTERA Enterprise File Services Platform happened recently in a firmware upgrade where there was a major database back-end upgrade and that took some time. For our smaller sites, it would be an hour or two, and I can build that into a fairly easy change window. But in our larger sites where we may have hundreds of terabytes of data, that database update process took maybe a day or a day and a half. That becomes more challenging, especially in a manufacturing environment where people are wanting to access configuration files. We had to pin the data locally because the data would be available on the local edge filer, but the cloud sync, while it was updating the database, the cloud files weren't available. That would be the other thing I'd like to see an improvement on: some way to do those database upgrades either in a more segmented fashion or in some type of offline environment. I understand the logistics behind that sounds easy, but I'm sure it's not.

Quotes from Members

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

Pros

"We used it for disaster recovery perspective behind a number of resources, like batch services and RDS."
"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."
"CTERA Enterprise File Services Platform has positively impacted our organization as it has allowed us to shrink our on-premise file system footprint, moving out from data centers and adopting a cloud-first strategy, which brings cost savings."
"The CTERA Enterprise File Services Platform is a hybrid solution that supports both on-premises and cloud environments."
"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 best feature is the migration tool within CTERA."
"CTERA's instantaneous and redundant file replication, available across multiple geographical locations, ensures easy and user-friendly recovery."
"CTERA Enterprise File Services Platform has positively impacted my organization in that it works as a file server, and centralizing things makes managing them in one location simpler than managing them everywhere else."
"CTERA Enterprise File Services Platform has positively impacted my organization by making our data management better, giving us greater security in our use, and letting us work easier with all the file services we need."
"I have seen a clear return on investment, and I would estimate that CTERA Enterprise File Services Platform saved about 50 to 60 percent of the costs tied to our old file storage and backup setup."
 

Cons

"I've been facing a challenge when doing a failover from FSx side. AWS console does not refresh within a half hour."
"A direct FTP feature would be beneficial instead of relying on transmission services."
"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."
"In my experience, CTERA Enterprise File Services Platform is not stable."
"It has a learning curve."
"There needs to be improvements, particularly regarding real-time sync conflict resolution and cloud latency."
"I am looking for a process where version upgrades do not impact the customers. There is no downtime."
"CTERA Enterprise File Services Platform could be improved by being a little faster in performance and having a timeline for new features and updates."
"There’s an issue with permissions, they aren’t always as transparent for customers as Microsoft’s, for example."
"AI and automation features could enhance the platform, such as AI-powered search, predictive storage analytics, and intelligent alerts for proactive monitoring. Predictive storage analytics will help with better capacity planning. There can be some sort of intelligent alerts for proactive monitoring."
"There are two things about CTERA Enterprise File Services Platform that I think they can improve. The first one is the reporting or maybe the monitoring solution because they lack reporting about the shares that we have, the used space, the total space, the permissions, or other relevant metrics."
 

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 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."
"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."
"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 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."
"So far, pricing seems to be fine."
"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."
