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.

Senior Manager at a manufacturing company with 10,001+ employees

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."

"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 shared storage capability is highly valuable."

"FSx operates as an independent service, not tied to any server, which eliminates dependencies between applications for storage."

"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 Enterprise File Services Platform helps us when they break something or lose things, and 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."

"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."

"CTERA stood out due to its ease of use and superior security features."

"The solution provides data eviction, where unused data is evicted from the local file, freeing up space. It also allows data to be rehydrated from the cloud when needed."

"It is a three-in-one solution for us. It is a file-sharing platform, an archiving solution, and also a backup solution."

"CTERA's instantaneous and redundant file replication, available across multiple geographical locations, ensures easy and user-friendly recovery."

More CTERA Enterprise File Services Platform pros

Cons

"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."

"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."

"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."

"It has a learning curve."

"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."

"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."

"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."

"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."

"However, in some cases, they could improve performance."

"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."

More CTERA Enterprise File Services Platform cons

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."

"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."

"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 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."

"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."
