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."Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"We're able to get higher-density workloads on the same infrastructure, and we have a smaller physical footprint. The performance is excellent – during our test the bottlenecks are never on the X array, it just keeps picking up the pace to match what you need. The real-time visibility is a differentiator in my opinion."
"The high availability of the product is the most valuable feature."
"The Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."
"The initial setup was extremely simple and straightforward."
"It's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."
"The duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."
"Pure has signature security technology, which cannot be deleted, even if you are an administrator."
"The most valuable feature is the simplicity of the backup and restore functions."
"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 Management Console (NMC) is super valuable, and both physical and virtual filers are also valuable. NMC is the one-stop place for all our filers, both virtual and physical filers. They are definitely doing a great job in housing all our documents and surveillance videos."
"Nasuni is tremendously easy to manage. It eliminates many of the administrative challenges associated with physical hardware storage, and you don't need to worry about any hardware failure or products reaching the end of their lives."
"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 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."
"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."
"The Nasuni management dashboard is helpful because, on the administration side, I'm able to view all of the different filers that we have in the UK, rather than check each one of them individually."
"This has been one of the most reliable storage systems that I have ever used."
"The solution is useful for machine learning and scientific applications, including computer simulations."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"We've seen that when we create a POD in synchronous mode, it increases the latency."
"The tool's pricing is higher than competitors."
"The software layer has to improve."
"I'd like to see the product implement active replication for vehicles such as VMware."
"In terms of what needs improvement, the dashboard and management could be simplified."
"The tool's portfolio is minimal. It is expensive."
"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."
"Some of their cross-platform features are really good, but it could always use more."
"I would like to see them improve their tools in regards to accessing data using smartphones, tablets, and iPads. I think the Nasuni app could be improved to make access to the data cleaner and more efficient."
"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."
"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."
"There are some issues with multiple users accessing the same file simultaneously. There would be times when the global file would lock when several people tried to access it, so that could be optimized more."
"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 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."
"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."
"The read/write ratio is an area in the solution with some flaws and needs improvement."
"The write performance could be improved because it is less than half of the read performance."
Nasuni is ranked 1st in Cloud Storage Gateways with 35 reviews while VAST Data is ranked 17th in All-Flash Storage with 2 reviews. Nasuni is rated 8.8, while VAST Data is rated 10.0.
