We performed a comparison between IBM FlashSystem and Nasuni based on real PeerSpot user reviews.
Find out in this report how the two NAS solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."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 high availability of the product is the most valuable feature."
"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."
"It has good, reliable, fast storage."
"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"The solution is very straightforward to set up."
"Pure has signature security technology, which cannot be deleted, even if you are an administrator."
"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."
"The solution allows for easy migrations from previous products or vendors via its embedded storage virtualization function."
"The most crucial feature of IBM FlashSystem is compression."
"IBM FlashSystem is a powerful effective storage solution. Additionally, it is user-friendly, anyone can use it."
"The speed, performance, and stability are the best features of IBM FlashSystem."
"The valuable features are high availability, compression, and a failover mechanism. It's a very highly available storage solution."
"The most valuable features are, of course, the virtualization of the storage, the performance, and the compression."
"The FlashSystem 900 consistently delivers performance below 1ms for read/write. This performance is essential for an effective SVC stretch-cluster configuration across two datacenters, and presenting active-active storage to the customer."
"The performance of IBM FlashSystem is very good. The new technology and high throughput have given us more confidence in the solution. The management of the system has improved and we can control the monitoring system alerts and multiple FlashSystems with the Enterprise Cloud Edition, which is free. The migration of recently stored data to a new flash is much easier. You can move your data because you can utilize it externally."
"The most valuable feature is the simplicity of the backup and restore functions."
"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 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."
"The global file locking feature is valuable. The ability to quickly deploy new sites is also valuable."
"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."
"One of Nasuni's best characteristics is its fully redundant system; we don't have to shift tapes or use other backup solutions. It's a good, full-featured product."
"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."
"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."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"The UI for this solution needs to be improved."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"The software layer has to improve."
"I would like to see replication and DR features in the next release of this solution."
"There is room for improvement in the pricing of the product."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"One area for improvement is in the GUI, where host clusters are not properly dealt with. With Hypervisor host clusters, all hosts must see the same volumes in the same order. Using the concept of a “host-group” has been around (even with IBM) for many years, so why not with the V7000?"
"The generic functionality of IBM FlashSystem, IBM always dismisses using file share or sharing protocols inside their storage hardware, and they only focus on the block-level storage."
"Sometimes the performance is effective but it gets resolved in the process."
"This solution needs a management console where we are alerted to issues and can report them, or escalate them through email or another method."
"I would like to have a larger disk. Right now, you can get 57 terabytes in a shelf. Once they get the larger disk and you get larger capacities, it'll be even better."
"With regards to the IBM V7000 storage system, where we have multiple tiers of storage, a heat map would show I/O distribution across the tiers of storage."
"It could be easier to implement."
"I know they have a flashcopy manager, but it is extra software, an additional license, and some customers don't like to add addition costs to their infrastructure. If IBM could create, or include snapshot management within the GUI, that would really be helpful."
"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."
"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."
"We forecasted that the data at my client's organization would grow by about ten percent annually, but we are migrating more data because we are bringing in some servers that had not previously been within the scope of our license. We expected it would take us two years to reach a specific amount of data, but we hit that mark in one year. The licensing cost skyrocketed, so we need to renegotiate. It puts us in a bind because we are reliant on Nasuni for our service strategy. We can't deny our customers, but we also struggle to pay for that."
"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 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."
"It is difficult to configure Nasuni. Adding a filer is an easy task, but deciding where to add them, how many to add, and what size to add takes a lot of time. I have to analyze my existing storage to understand how many users are going to access which folders. I have to design the Nasuni architecture accordingly."
"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."
"Some of their cross-platform features are really good, but it could always use more."
