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.

Quotes from Members

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

Pros

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

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

"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."

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

"The high availability of the product is the most valuable feature."

"The latency is good."

"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."

"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."

More Pure FlashArray X NVMe pros

"The features I find most valuable include its use for storage and performance."

"The solution is more available for IOPS warehousing, resolving issues, and reporting than other products."

"The storage serves the virtual environment. Most of our applications run in the virtual environment, and it serves nearly 30% of the bank's capacity."

"A key feature is that compared to storage systems that we've been familiar with over decades, IBM simply does not fail. The reason is that IBM is the only manufacturer that engineers its own flash module, and there is a key architectural difference from everything else that we have seen in the market. The difference is that the flash module has the computational capability, which allows reliability and capacity enhancements to be uploaded from the main controllers and run in each module. So, each of the flash drives becomes its own little storage system, and that is extremely effective architecture. In this field, with this type of system, IBM has made a statement. They've never had one of these modules cause an outage. So, the failure rates on these things are just in a whole different universe from what we were accustomed to."

"Good performance with a user-friendly UI."

"Its ease of use, performance, and hardware compression is very useful feature."

"The most valuable feature of IBM FlashSystem 9100 NVMe is the snapshot. We use it daily for all of the storage units."

"The high performance and high availability improved our overall processes."

More IBM FlashSystem 9100 NVMe pros

"It has the ability to do end-user recovery, or a user can simply contact an admin who can perform a recovery from the management console. The versioning has simplified everything. Now we don't have to worry about those components."

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

"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."

"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 feature I have found to be most valuable is the revision control of the files. If somebody deletes or accidentally makes a wrong change to files, we can go back to the revision history and restore the previous versions. That is a very good feature that we rely on."

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

"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."

More Nasuni pros

Cons

"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."

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

"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."

"You cannot tag a LUN with a description, and that should be improved. What I like on the Unity side is that when I expand LUNs or do things, there is an information field on the LUN. This is the Information field that you can tag on your LUNs to let yourself know, "Hey, I've added this much space on this date". Pure lacks that ability. So, you don't have a mechanism that's friendly for tracking your data expansions on the LUN and for adding any additional information. That's a downside for me."

"We need better data deduplication."

"I'd like to see the product implement active replication for vehicles such as VMware."

"Right now, the box itself is just strictly working as a backend storage system. It would be fantastic if we could access it directly like a NAS device through network access or SIS drives. I think they have an interface, but I am not sure how good it is. If we could address a box directly on the network without having to go through a server, it would be great. The replication schemas could be improved. We are not using replication on the storage level right now. We use a different type of replication. If their replication would be as good as the one that we have, I would probably run the replication schema because it might be faster, but I don't know that for a fact. So, I cannot say that they have good replication. All I can say is that they need to inform us better."

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

More Pure FlashArray X NVMe cons

"The efficacy of the GUI in IBM FlashSystem 9100 NVMe could be enhanced, and it would be beneficial to include a feature that can prevent ransomware attacks."

"IBM FlashSystem 9100 NVMe is an expensive solution, and its pricing could be improved."

"Other vendors have included a block and file system. IBM doesn't include a file system. And yet, it's very necessary for all organizations' networks to have file systems. We have other systems for the file system, however, ideally, we would like to have one system with these features."

"In the future, the limitation is upgrading the same storage by adding a shelf to the desk. There is a limitation in the backend connection between the storage and extended shelf."

"I would like to see IBM products become more affordable because they can be quite expensive, which limits their accessibility to a broader customer base."

"In the FlashSystem 5200, there were only four ports of 32 fiber channels for the architecture. This has been resolved in the new generation."

"The support could be better."

"The solution's compression needs to be improved, as it's not the best."

More IBM FlashSystem 9100 NVMe cons

"The privilege settings need to be more granular, and alerts are an excellent example. If a user doesn't have access to them, they can't see them and access information such as what they may have done wrong, what's there, and when the last sync happened. However, the ability to view alerts also comes with permission to delete them, which is not good, so we need more customization options here."

"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."

"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."

"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."

"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."

"I would like to see improvement in the training Nasuni provides. Compared to some of the other vendors out there, like Microsoft, where you can find how-to videos, Nasuni only has a lot of PDF documents that you have to go hunting for. It's workable, it certainly isn't a problem, but video walkthroughs would always be helpful."

"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 provides enough reporting to see what's happening. You can see the number of shares, total volume, issues, conflicts, etc., but it doesn't provide much visibility from a content perspective. For example, it doesn't tell you the data age. When you're trying to sort and filter information, the data creation date is a critical factor. Nasuni doesn't give you that. You can't get a count of all the file types, like the number of PDFs, Word docs, and PPT files."

More Nasuni cons

Pricing and Cost Advice

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

"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."

"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."

"Given its price, Pure is not the first option."

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

"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."

"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."

More Pure FlashArray X NVMe pricing and cost advice

"Price-wise, the solution offers excellent pricing to its users. In short, the prices offered by the solution are competitive compared to similar solutions."

"The price of the FlashSystem 9100 NVMe is reasonable."

"The price of IBM FlashSystem 9100 NVMe is less than Dell. For upgrades, the Dell solutions are more expensive."

"The product has an average cost."

"On a scale of one to ten, where one is a low price and ten is a high price, I rate the pricing an eight."

"Compared to its competitors, IBM's offering is the most cost-effective."

"The tool's pricing is competitive."

"The solution is priced well."

More IBM FlashSystem 9100 NVMe pricing and cost advice

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

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

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

"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."

"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 has a license fee as well as hardware costs, which we would incur if we want to use Nasuni Cloud Storage Gateway for upgrades."

"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."

"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."

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.
