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

"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."
"Apart from time-saving, CTERA Enterprise File Services Platform provides secure file access and centralized control, which are measurable benefits for me."
"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 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."
"CTERA is a very scalable product, allowing us to grow."
"The best feature is the migration tool within CTERA."
"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 performance is outstanding, and customers are very happy with it."
"The DDN Exascaler uses a parallel file system, Lustre, which is proven for HPC and AI workloads."
 

Cons

"There’s an issue with permissions, they aren’t always as transparent for customers as Microsoft’s, for example."
"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."
"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."
"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."
"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."
"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."
"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."
"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."
"There are challenges with the operation cost and upgrading process, which is disruptive, especially with the node."
 

Pricing and Cost Advice

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