It helped us save 40 to 45 percent on some types of data

It can provide a 360-degree view of your data, depending on how you implement it and whether you're storing your data in Nasuni. However, if you're working with multiple cloud providers, I don't think it's mature enough to provide a 360-degree view of what's in AWS, Azure, and Google Cloud. I think it can do it, but it's still a lot of scope and range fitting. Given that Nasuni storage is actually cheaper in some areas, it made sense for us to move a lot of our data away from Microsoft. Nasuni gave us more of a 360 view of that particular data type. Other data types are a little different because the company went in a direction where they wanted to store some stuff in an AWS S3 bucket rather than a file storage system. An S3 bucket has its advantages, but if you were to store more of your data in Nasuni, you would get a wider 360-degree view of it rather than on several cloud providers. I have data in AWS, Google, and Azure, and I would like to see a wider view of all the data stored across these three top providers. Currently, I use it for AWS and Azure, but I couldn't use both of them at the same time. I think Nasuni could have better visibility across these different areas. I had to take my data out and then do some analysis to get the costs. It would be helpful to have more built-in analytics tools to compare the storage costs between the various cloud providers. I would also like some graphing capabilities. We had a tool called Grafana that we used for graphing. I think some more visual analytics like that would be nice.

Quotes from Members

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

Pros

"The most valuable feature is the storage in that it only keeps the last-used data locally, while everything else is backed up to the cloud. That way, we never really have to worry about file space in each office or the replication to the other file servers for DR."

"The most important feature is that things are backed up automatically in AWS. We have a lot of remote sites where there is a tiny server onsite and, in a lot of cases, we really don't have to back them up because the data is automatically copied to AWS. The cloud replication is the most useful functionality for us."

"Nasuni gives us a single platform with a 360-degree view of our file data, which is very important to us. We have everything that we need to look at in a single pane of glass."

"I like the unlimited snapshotting."

"My clients are happy with Nasuni because the transmission is seamless, and it consolidates all the existing file servers into one location. Also, Nasuni has no boundaries. It's infinitely expandable. They don't have to rely on the service provider for backup and restoration. It's self-serve."

"The nice thing about Nasuni storage is that it is immutable. This means the data is only written once. So, you never modify the files. When you write a file out to the storage, it doesn't modify it when you change it. The technology knows how to figure out what the difference is between the original file write and what the changes are. Therefore, it only saves the changes."

"The biggest and most impressive thing for us is the operational recovery (OR) and disaster recovery (DR) capabilities that Nasuni has. If a filer goes down, or an ESX server goes down, then we can quickly recover."

"I can see who is logging in on files from all over the globe. For example, if a file is locked, maybe a user in Shanghai has locked files or something, I can see that from the Management Console, then unlock the file."

More Nasuni pros

"The replication capability and data security have been the most valuable features."

"It is not necessarily for the fastest storage or cluster storage, but just for pure storage, it's really hard to beat. It's just been around as long as anything else."

"Oracle ZFS is very fast and it is efficient. It has outperformed any hardware array controller that I've ever come across. With Oracle ZFS on my NAS, which is running five, four terabyte drives, when I've had a drive failure and changed one out, it'll rebuild that array in two hours, or maybe less. When you think you're rebuilding almost four terabytes of data redundancy, that's pretty good using an old AMD Turion hardware, that's nothing to complain about."

Cons

"Nasuni does not support different retention policies within the same volume, so you have to keep creating volumes for retention policies. When you create a new volume, it means you're starting from zero all over again. You can't move data between two volumes. You have to move them from your physical device to Nasuni or your cloud device to Nasuni."

"I would like to see Nasuni provide the ability to mirror a Nasuni appliance from one site to another. They could maybe have a standby appliance that is mirrored in a different location for disaster recovery purposes. We can recover if data and a Filer are lost because of a possible ransomware event, but even that takes time to recover. If we had the ability to have a mirrored appliance, we could flip over to that mirrored device and resume instantly rather than repopulate the local appliance with data from the snapshot history in the cloud. This is another feature that we would really like to see, if possible."

"I would like to see improvement in the training Nasuni provides. Compared to some of the other vendors out there, like Microsoft, where you can find how-to videos, Nasuni only has a lot of PDF documents that you have to go hunting for. It's workable, it certainly isn't a problem, but video walkthroughs would always be helpful."

"Some applications may not be suited for the Nasuni environment. You may need something with better performance. Otherwise, if you want to run daily operations or some file system, it's a good bet."

"The Nasuni file storage platform doesn't work well when there are a high number of small files. This is the case when a directory structure contains more than 10,000 or 20,000 small files, e.g., 5 KB, 10 KB, or 15 KB. When the user is accessing these files from another geographical location, they might face a slow response or timeouts when connecting to the shares, and then to the files. This is because the file size is small. There is a scope of improvement with this solution when it comes to accessing a large number of small files."

"As administrators, we are used to having control equal to managing an on-prem device. In terms of log analysis and other things we want to do, Nasuni has some limitations limitation on what you do on the Nasuni. Nasuni could add some features to the GUI that make administration a little easier. It's tough when I have to move from one filter to another because there is no way to search it. We have to scroll up and down to find the name of it."

"We forecasted that the data at my client's organization would grow by about ten percent annually, but we are migrating more data because we are bringing in some servers that had not previously been within the scope of our license. We expected it would take us two years to reach a specific amount of data, but we hit that mark in one year. The licensing cost skyrocketed, so we need to renegotiate. It puts us in a bind because we are reliant on Nasuni for our service strategy. We can't deny our customers, but we also struggle to pay for that."

"The only issue we face with Nasuni is from the performance perspective. Sometimes, when we deploy a Nasuni device, it doesn't meet our requirements. It's a capacity-planning issue."

More Nasuni cons

"ZFS is great for just mass storage, but if you're trying to make fast storage – something like a SAN-type delivery network where you wanted to do any type of RAM disc over the network – it falls flat. ZFS does not do that. It is kind of limiting."

"Oracle ZFS does what I've asked it to do, and it has done it very efficiently. The only time I'm running into issues is with Proxmox. If I run ZFS drives, I find my RAM usage is very high. However, I don't have that problem with the TrueNAS system, where I'm running an old N36 Turion with four gigabytes of RAM, and that's running 24/7. There have been no issues with such a low-powered environment there, it works fine, but with Proxmox it seems to go slow."

"When retrieving data from the replication of remote sites, it does not give you immediate results. The RPO and RTO rates could be improved."

Pricing and Cost Advice

"With this solution, the license renewal is pretty swift. With the virtual appliance, you just need to take care of the OS versions and patches. In a way, we don't have to struggle much with renewals because the only thing that we need to take care of are the licenses. We renew it every three years. This aspect goes with infrastructural costs because it doesn't cost us too much to maintain the solution."

"Its price is fair and reasonable. I don't have anything negative about its pricing and licensing. For us, there is also the cost of monitoring. We are monitoring through Xenos and not through Nasuni. That is another cost for us from the monitoring perspective, but as far as Nasuni goes, we don't have any other cost apart from the licensing fee."

"The pricing is fair. It's an enterprise-level solution so it's not inexpensive... The cost is pretty stable year over year."

"The cost is based on the capacity, which is approximately $100 USD per terabyte."

"Nasuni pricing is average; it's not too high or too low."

"The pricing is on par with everybody else, and fair."

"It's cheaper than a lot of alternatives but it's not cheap."

"It has a license fee as well as hardware costs, which we would incur if we want to use Nasuni Cloud Storage Gateway for upgrades."

Reviews from Real Users

James J., IT Manager at a marketing services firm, says Nasuni’s management dashboard is helpful because he's able to view all of the different filers at once rather than check each one of them individually. He values the software’s security, reliability, good performance, helpful alerting, and responsive support.

According to a Server Engineering Services Lead at a mining and metals company, Nasuni offers good OR and DR capabilities, performs well, offers data security, and continuous file versioning helps recover from hardware failures.

The Managing Director of IT at a construction company appreciates Nasuni because it eliminates a lot of work that was previously done when managing backing up and restoring data files.
