Helps to save money and resources with the data compression feature

One point I'd like to improve is that the tool should start selling small boxes again. It discontinued some products and is focusing on bigger, more capable boxes, neglecting the SMB market. Even though it's not a big market, it shouldn't have removed them. One way to improve the product is to add an operational assistant that doesn't depend on VMware. It could also establish more alliances with other operational systems.

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.

Stability-wise, a device that has been up and running for years

The failover capability and resiliency are some of the solution's valuable features. The big thing is resilience because it has richer coding in it, so multiple devices can't fail. Also, one can still access a number of CBoxes that can allow one to access their file system. Once a device fails, it fails the transparency of the end-user, and it just starts using another resource. The encryption capability, the snapshots, along with a whole bunch of features make the tool valuable. VAST Data keeps adding more and more features all the time.

Quotes from Members

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

Pros

"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."

"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."

"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 most valuable feature of this solution is reliability."

"The tool's valuable features are speed, security, data compression, and reliability. Its data compression feature is the best that we have ever seen. It helps us to save money and resources."

"The most valuable features of this solution are its ease of use and performance."

"What I really like about this program, is that it is easy to use and easy to configurate."

"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."

More Pure FlashArray X NVMe pros

"The most valuable feature is disaster recovery. We can fully recover a site in two hours."

"The features I find most valuable in Nasuni are the unlimited snapshots, antivirus capabilities, auditing, and ransomware protection."

"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."

"Nasuni has helped to eliminate on-premises infrastructure. We were using about eight to 10 different types of vendors or small storage boxes for provisioning and shared access for users. We got rid of all those. That has eliminated operational overhead and footprint at our data center. We don't have to worry about any hardware or monitoring particular devices, and hundreds of devices have been decommissioned. Now, for provisioning, everything is on Nasuni. I assume this has made a big difference in costs."

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

"The most valuable feature is the simplicity of the backup and restore functions."

More Nasuni pros

"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."

Cons

"Managing data isn't difficult for me. The performance is usually perfect, but we sometimes have capacity problems."

"In the next release, I would like to see real-time analytics for further insight into consumption models."

"The UI for this solution needs to be improved."

"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."

"One point I'd like to improve is that the tool should start selling small boxes again. It discontinued some products and is focusing on bigger, more capable boxes, neglecting the SMB market. Even though it's not a big market, it shouldn't have removed them."

"Adding some functions to the product would be beneficial. Storage replication should be essential, and the analytics should not incur extra charges."

"I would like to see some AI features that would allow arrays to intelligently identify threats or unusual behavior in the data pattern and give an alert."

"Our use cases require more multi-tenant capabilities and additional VLAN interfaces for separating different customers. We currently use it to provide storage, sometimes shared storage, to different customers, but it is less flexible in comparison to a dedicated solution."

More Pure FlashArray X NVMe cons

"Its interface design or the graphic user interface design can be slightly tweaked in some areas. Some built-in setup wizards would be very beneficial. Rather than having to go in and configure it by hand, there should be more setup wizards for onboarding new data shares and getting it set up the way you want. I don't know if these are on their roadmap, but I sat down and talked to them about some of the work concerns, some of the things that we liked, and some of the things that we didn't like. They are probably working on that."

"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."

"Nasuni recently implemented a health system for filers. However, it needs better visibility because it lacks data and an explanation, or reasoning as to why a particular filer may be unhealthy."

"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 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."

"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."

"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."

"When we first set up our bandwidth limiting, we had a few problems when it came to managing it. This is something that could be made easier; however, we were able to make the changes that we needed to for our environment."

More Nasuni cons

"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."

Pricing and Cost Advice

"As far as the licensing costs, everything is included in the license."

"With Pure Storage, we would like to continue seeing price reductions with flash storage. I don't think we're any different than anybody else when we continue to look to the industry for price reductions of both NVMe and traditional SSD storage. We would like to see these prices continue to decline and erode, even displacing large spinning disks."

"Pure FlashArray X NVMe’s pricing is cheaper than other products."

"The tool's pricing is cheap; I rate it a six to seven out of ten. Most of our sales are not subscription-based. We sell the hardware, and customers keep using it. They only renew the service part annually. The support can be a bit pricey, but the solution is more cost-effective than anything else out there."

"The support cost per array is about $20,000 a year for 24/7 support."

"The licensing is on a yearly basis."

"Our licensing fees are $500,000+ USD."

"With VMware, we pay $300,000 annually."

More Pure FlashArray X NVMe pricing and cost advice

"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."

"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."

"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."

"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."

"There are cheaper forms of storage, but Nasuni is fairly priced for the functionality it offers. I can get basic file shares provisioned in Azure and pay for the storage and the CPU. The overall cost would be much less than Nasuni, but I would need to build the management console and encryption process, so it would cost a lot to develop that kind of functionality."

"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."

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

More Nasuni pricing and cost advice

"We acquired VAST Data as a one-time, capital purchase."

"Price-wise, VAST Data is not the cheapest, not the most expensive one."

Overview

Pure Storage FlashArray//X is the world’s first enterprise-class, all-NVMe flash storage array. It represents a new class of storage – shared accelerated storage, which is a term coined by Gartner – that delivers major breakthroughs in performance, simplicity, and consolidation.

Pure Storage

Nasuni is a file data services enterprise focused on assisting firms with their digital transformation, global expansion, and information awareness. The Nasuni File Data Platform is a suite of cloud-based services designed to enhance user productivity, ensure business continuity, provide data intelligence, offer cloud options, and simplify global infrastructure. This platform and its auxiliary services are projected to replace conventional file infrastructure such as network attached storage (NAS), backup, and Disaster Recovery (DR), with an expandable cloud-scale solution. By storing file data in scalable cloud object storage from multiple providers, Nasuni positions itself as a cloud-native alternative for traditional NAS and file server infrastructure. Based in Boston, Massachusetts, USA, Nasuni serves sectors like manufacturing, construction, technology, oil and gas, financial services, and public sector worldwide, offering its services in more than 70 countries.

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.
