Featured Reviews

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.

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 solution uses newer technology for deduplication and compression."

"It offers competitive performance, and the Evergreen storage model of Pure fits well with my organization."

"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."

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

"The solution is scalable."

"It has benefited my organization because it has reduced time to insights."

"The database workloads are pretty fast because I frequently move data from here to there."

"Pure Storage has signature security technology, which cannot be deleted, even if you are an administrator."

More Pure FlashArray X NVMe pros

"The solution's initial setup process is easy."

"Lenovo ThinkSystem DE Series is quite an elementary box, no frills. It does not have all the functionality of the DM but it is acceptable, it does its task. It integrates pretty well."

"ThinkSystem's storage performs well, and the price per gigabyte is good, especially on SSD solutions. It's also easy to use."

"Lenovo ThinkSystem DE Series is highly reliable, especially for block-level storage. It is stable, with minimal downtime and no issues beyond user errors."

"The most valuable features of the Lenovo ThinkSystem DE Series are the dual controllers, available installation documentation, and the option of multiple host bus adapter interfaces."

"The solution is very easy to set up."

"This solution is good for virtualization and meets the need for CPU and RAM requirements."

"Lenovo ThinkSystem DE Series is simple to use"

More Lenovo ThinkSystem DE Series pros

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

"I like the unlimited snapshotting."

"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."

"Continuous File Versioning is one of the best features because it helps you to restore at any point in time. That means you don't have to worry about a ransomware attack. Even if that attack happens, you can restore all the data to five minutes ago and save everything."

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

"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."

"We've used it to provide file source capacity for VDI environments. The security of it is important and the fact that it's object storage, it's immutable and that it can't be held for ransom. It's a lot smoother than our previous processes that weren't Nasuni-based. A lot of it is done automatically just by the system being in place."

Cons

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

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

"Adding some functions to the product would be beneficial."

"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."

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

"There are some challenges with data encryption and reduction."

"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."

"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."

More Pure FlashArray X NVMe cons

"There could be a snapshot feature in the solution."

"The features are limited."

"Improvements can be made to the product's performance."

"It would be useful to have structured solutions replicated to other sites."

"The type of connection that is used in Lenovo ThinkSystem DE Series should be improved."

"The difficult part comes when dealing with the host. You have to enable multi-pathing and other aspects that are needed for proper configuration. I don't know if there is room for a more hyper-conversion structure to work with, but this would be easier."

"The solution could be more scalable, although it suits our present needs."

"In the next release, I would like to see more functionality. But, again, it is an entry-level product."

More Lenovo ThinkSystem DE Series cons

"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."

"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."

"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."

"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 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."

"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."

"When we have to rebuild a filer or put a new one at a site, one of the things that I would like to be able to do is just repoint the data from Azure to it. As it is now, you need to copy it using a method like Robocopy."

"One thing to consider is that Nasuni will have the same limitations that a traditional file storage solution will have, although that is because they are taking the place of a traditional architectural model. For example, Office 365 supports collaboration on documents such as Excel files and Word documents, but because Nasuni is a traditional file server, in that sense, it can't make use of that functionality."

Pricing and Cost Advice

"The product is expensive."

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

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

"The licensing is on a yearly basis."

"The tool is an investment that we've budgeted for. While the prices may be higher than those of other vendors, we see it as a market leader with benefits. We don't regret purchasing it."

"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."

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

"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

"We have a five-year contract for providing support."

"The pricing for this solution is good compared to HP or Dell EMC."

"The solution's price could be better."

"The pricing is fair and low compared to other products in this category."

"All of the features are bundled together, and you can renew the bundle with all of the features included."

"It is an expensive solution."

"The best thing about this solution is its price, which reduces our costs."

"The price of the Lenovo ThinkSystem DE Series is a one-time purchase. There is a global price list available to find the price of the solution."

More Lenovo ThinkSystem DE Series 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."

"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."

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

"Its pricing can get a tad expensive. When we first took Nasuni out, we were just paying for the service. We got storage at a reduced rate. It has now changed, and they're now more of an all-in-one type of thing. It can be quite expensive, but it works out. Apart from that, licensing-wise, it's very simple."

"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."

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

"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."

Lenovo

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.
