Featured Reviews

Jaehoon Oh

Chief Technology Officer at Lambda256

Supports efficient storage management through volume snapshots and offers reliable non-disruptive upgrades

I have no specific improvements to suggest for Pure FlashArray X NVMe at this time. The performance statistics could be enhanced. I can see the performance statistics in the Pure Storage console, but it does not show the performance by 4K byte unit. It displays IOPS and bandwidth, but IOPS is about real use, and I want to know how many IOPS are currently running in 4K byte units. I cannot see that IOPS because most storage systems report their performance by 4K byte unit. I want to see Pure Storage performance by 4K byte unit to compare with other storage or other internal NVMe SSD.

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

"The most valuable features of Pure FlashArray X NVMe are its superior performance compared to other flash tiers, as well as its ease of use, with an intuitive user interface that is simple to deploy and use."

"I appreciate the performance."

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

"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 solution is scalable."

"The latency is good."

"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."

"It is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."

More Pure FlashArray X NVMe pros

"We use Nasuni's continuous file versioning feature and it fully protects us. With the ability to version files and have continuous recovery, it helps in terms of resiliency. If we have an incident then we would be able to easily recover from it by using the technology."

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

"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 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."

"Its dependability and auditing capabilities are very important to us to be able to maintain a chain of custody of the information."

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

"The solution gives us a breakdown and summary of every resource and each volume within every resource. It tells us the code within a given volume, so I can go in there and look at the size of the files that are stored there. Nasuni gives me the big picture and allows me to connect things like Power BI to any endpoint. I can take that tabular information from Nasuni and look at it in a graph."

"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

"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

"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."

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

"It is on the expensive side."

"It's more multi-tenant functionality in their Pure1 manage portal that is lacking."

"The software layer has to improve."

"We need better data deduplication."

"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."

"They could add more support for file storage and different types of storage."

More Pure FlashArray X NVMe cons

"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 customer portal could be improved, but it has been a while since I've used it. They might already have improved it."

"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 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."

"Some of their cross-platform features are really good, but it could always use more."

"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 performance monitoring could be improved."

"The only thing that I'd like to see is more support for platforms like OneDrive or Box.com."

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

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

"Pretty much everything that you need is licensed when you buy the product. Licensing to me is different than the maintenance cost, but they can bleed into one another. We buy the product, and we expect three years of support bundled into what we negotiate on our storage arrays. I would start to see maintenance costs going into the fourth year, but we're not there yet."

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

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

"We pay approximately $50,000 USD per year in licensing fees."

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

"The product is expensive."

"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."

More Pure FlashArray X NVMe pricing and cost advice

"They could lower the cost, but it saves so much money when you go into it (by losing all the backup)."

"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."

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

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

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

"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."

"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."

"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."

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.
