We performed a comparison between Nasuni and VAST Data based on real PeerSpot user reviews.
Find out what your peers are saying about Dell Technologies, NetApp, Pure Storage and others in All-Flash Storage."The most valuable feature of Pure Storage FlashArray is the complete set of functions it provides."
"It is fast and reliable. It works."
"It is all-flash. This makes it a lot faster than the rest of what we have, as it is able to drive high I/O loads, which is big for us."
"The most valuable feature of this solution is the support."
"The stability and performance are the best things about the solution."
"Most of the problems that we had in the past with the performance in IOPS have disappeared. It has been a great improvement for our customers' services."
"It worked flawlessly."
"The data reduction technology part of the scalability has been impressive, like its ability to host additional workloads, volumes of data, and databases."
"We have less downtime and fewer trouble tickets from users who cannot access their shared files. Nasuni has reduced the friction and noise associated with file management because the devices are more reliable."
"The snapshot functionality and the unified file system are definitely the most valuable features for us. The UFS allows everybody across the organization to see the exact same data at the same time, instead of having different file servers with different structures on them, and that's mission-critical. We have different branches throughout our organization that have to act on that data."
"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 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 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."
"Another helpful feature, in addition to restoring a file that was deleted within 24 to 48 hours, is that we have the ability to restore a file or a folder that was deleted, going all the way back to the inception of that file or folder. That means we actually have unlimited backups to the inception point of data with Nasuni."
"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."
"The solution is useful for machine learning and scientific applications, including computer simulations."
"This has been one of the most reliable storage systems that I have ever used."
"The solution could improve by having a multi-tenant feature."
"On a couple of occasions, the waiting time for an upgrade has been pretty substantial."
"The price of the solution can improve."
"Beyond a certain amount of petabytes, you have to have a separate system. Basically, it's not infinitely scalable."
"Automation could be simplified."
"The system has dual controllers but does not have a high level of resiliency built-in."
"The price of Pure Storage FlashArray could be better."
"I would love to see a true one click upgrade solution. Right now, you have to click and schedule an appointment with Pure Storage to be able to upgrade. I would love for it to automatically download, install, and fall-over every controller as it updates."
"It is difficult to configure Nasuni. Adding a filer is an easy task, but deciding where to add them, how many to add, and what size to add takes a lot of time. I have to analyze my existing storage to understand how many users are going to access which folders. I have to design the Nasuni architecture accordingly."
"We would like to have a user desktop agent to help improve the end-user experience."
"I would like to see Nasuni create a Dropbox or Box alternative. One of the things that people like about those tools is that they are very easy to implement. They look just like a file server. With Nasuni, you have to be online to get your file storage. With Dropbox, there is a thing running on your PC that downloads the files to it when you need them, i.e., an agent."
"The user-friendliness of its access needs improvement. When I log into the console, I see all the files that we handle globally. There are hundreds of Nasuni files that I can see on the console, but no way that I can filter them down. While this is a small thing, I need to scroll down and select the ones that I want. "Control F" doesn't work nor is there a dropdown menu that I can click on and select the ones that I want."
"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."
"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."
"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."
"The only thing that I'd like to see is more support for platforms like OneDrive or Box.com."
"The write performance could be improved because it is less than half of the read performance."
"The read/write ratio is an area in the solution with some flaws and needs improvement."
