Open-source with great disk management and task synchronization

The system itself allows you to add any feature. The only bad thing is that this maybe depends on FreeBSD, and sometimes finding documentation is difficult. For example, we knew that previous versions automatically enabled the Linux kernel, yet with the recent version, this was no longer the case. Now, there was the possibility of being able to create Debian-based jails, and finding the documentation was not easy or fast. That said, in the end, we succeeded. If you find the documentation, it is always incomplete and fragmented.

Cloud data management that achieves cost efficiency with advanced data protection features

I am currently using Nasuni for seismic data. We have a huge data size, and we want to reduce costs. Nasuni acts as a caching solution, so we put some data into the cache, and the rest goes to the blob, which helps us save on costs. We use it for applications like Petrol and Tech Log, where 3D…

Quotes from Members

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

Pros

"The stability is quite good; our system is in production and we have not had any problems with it, and when a drive fails, we don't really have any disruption because we can easily rebuild the disk, even if it is very large."

"After using FreeNAS I will never spend money for commercial products like Dell or 3Par."

"The program is fast, fun to work on and easy."

"The fact that no data are lost when a hard drive fails is extremely reassuring, as I have had two of five drives fail at one time and no data were lost."

"It integrates well into either Windows or Linux environments."

"It has the best storage capacity."

"The solution has been very stable so far."

"The ease of use of the 'jail', the management of backups, and copies to easily create test and pre-production scenarios have speeded up the development and distribution of business apps."

More FreeNAS pros

"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."

"The global file locking feature is valuable. The ability to quickly deploy new sites is also valuable."

"The disaster recovery capabilities are very easy because their virtual appliances are just like OVFs or images. You put in a code and it collects all the configuration from the cloud and then builds up the cache. But that doesn't preclude the device from easily being restored or recovered at short notice."

"My advice for anybody who is considering this product is that it works great."

"The most valuable feature is that we have redundancy in our data. It's nice to know that it is cached both locally on the filters, as well as stored on that cloud."

"I can't say anything other than good things about it."

"Nasuni reduced our overall storage footprint at our sites by 70 to 80 percent."

"Snapshot backup is most valuable. It's quick and easy to use. It's controlled only by an administrator, which is very good. It takes 10 seconds to back up a spreadsheet of three or four megabytes."

More Nasuni pros

Cons

"The latest version of the dashboard doesn't work as good as the previous version. Sometimes we change our dashboard back to the previous version because the latest version just doesn't work as good."

"They should include clustering for the solution."

"If you find the documentation, it is always incomplete and fragmented."

"Make it easier to find out how to fix things when something goes wrong."

"The one thing that I find difficult to do which is very time-consuming is that I like to have a backup of the important files."

"Its support for Hyper-V clusters."

"FreeNAS should be better prepared for clustering."

"One of my hard drives has failed and the documentation that I've been able to find has not helped."

More FreeNAS cons

"The speed at which new files are created is something that could be improved. For example, if you create a new file in another country, I won't see it for between 10 and 15 minutes."

"Customer support and response time on issues should be improved because their support can be hard to get in touch with and we have to wait for a long time to get a call back."

"Nasuni could improve cloud integration and documentation of various ways we can leverage the product. It integrates with Azure, but the native Azure File Sync solution lets you divide data into tiers like hot, cool, and archived. Nasuni doesn't allow you to break the data apart into those tiered categories."

"Part of the problem seems to be that Nasuni currently is not set up to do 24/7 support; they said that they were going to do that, so that was a little disappointing."

"Migration from existing systems, specifically StorSimple, could be improved, but that solution will be end-of-life by the end of the year. Also, the documentation could be more accessible."

"There is some room for improvement when it comes to monitoring. We are not using Nasuni monitoring. We are using our own monitoring through Xenos. Nasuni can provide better monitoring capabilities for us to monitor all the filers and NMC so that we don't have to use a third-party tool."

"We can recover if data and a Filer are lost because of a possible ransomware event, but even that takes time to recover."

"The performance of the filesystem could be improved."

More Nasuni cons

Pricing and Cost Advice

"We use the free version of the program."

"Its licensing cost is based on the hardware capacity."

"Its price is okay. It suits our needs."

"For our configuration, we pay a little bit less than €10,000 ($12,000 USD) per year."

"It is around $850 per terabyte per year. Any additional costs that you would incur are for the local caching devices that you'll need to access Nasuni. You kind of provide your own virtual machines or compute to access the data. You also pay for the object storage. So, there are three parts to it. There is the Nasuni license per terabyte. You would also pay for the actual object storage in the cloud, and then you would pay for virtual machines to access the storage."

"The cost of licensing is negotiated and billed annually per terabyte."

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

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

"I would not say it is economically priced, but it is affordable. If you can afford to pay for it, it is worth the money, but it is definitely not overpriced. It is priced about where it needs to be in the market. We were satisfied with the way they did their licensing and how they handled it. I believe they actually license by data size. It is based on how much data is being held on the machine and replicated, and that's completely understandable. So, for us, their pricing was as expected and affordable."

"Nasuni should provide small-scale licenses, like a 20 TB license. Currently, the smallest is a 30 TB license."

"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."

"Our agreement is set up such that we pay annually per terabyte, and we buy a chunk of it at a time. Then if we run out of space, we go back to them and buy another chunk."
