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.

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

"On a scale of one to ten, I would rate Amazon FSx a ten."
"The shared storage capability is highly valuable."
"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 rate the stability of Amazon FSx ten out of ten."
"The replication workflows have replicated content to our branch offices and cached that content, which makes that content accessible to our regional offices around the globe and makes accessing that data much easier and much faster."
"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 user interface of CTERA Enterprise File Services Platform is fantastic, providing a centralized console where we can manage all our Edge Filers and configure them through a very user-friendly interface."
"It makes people think I have my superhero cape on because they're thinking it's all lost, they're doomed, and we're able to quickly and effectively go back and say, 'Here you go,' and it's not hours, it's minutes."
"It makes people think I have my superhero cape on because they're thinking it's all lost, they're doomed, and we're able to quickly and effectively go back and say, 'Here you go,' and it's not hours, it's minutes."
"CTERA has out-of-the-box data protection capabilities."
"CTERA's instantaneous and redundant file replication, available across multiple geographical locations, ensures easy and user-friendly recovery."
"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."
 

Cons

"A direct FTP feature would be beneficial instead of relying on transmission services."
"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."
"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."
"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."
"There are some micro-level loggings that would have been better in improvising, and all those details are in the pipeline."
"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."
"I am looking for a process where version upgrades do not impact the customers. There is no downtime."
"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."
"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."
"There needs to be improvements, particularly regarding real-time sync conflict resolution and cloud latency."
"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."
 

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."
"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."
"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 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."
"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."
"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."
"I am not directly involved in the pricing aspects, but I understand that CTERA's pricing is competitive and within industry standards."
