Sentiment score
7.3
Nasuni offers scalable, user-friendly data storage, efficiently meeting diverse organizational needs and supporting physical or virtual deployments.
We started on PowerScale with around about 300 terabytes and are now two and a half petabytes, still on the same file system.

That's really saved us in certain areas as we didn't have funding to expand Dell PowerScale (Isilon) until next year, which is why we utilized the cloud pools functionality to offload.
Senior Infrastructure Specialist at a healthcare company with 10,001+ employees
As an unstructured data storage solution, writing into it and accessing it from the other nodes is highly scalable with no issues.
Senior Technical Engineer at a tech vendor with 10,001+ employees
I rated the scalability as seven because even though the solution can scale, load balancing must be done manually, as it's not automated.

If I could improve one thing on Dell PowerScale (Isilon), it would be better object storage as it recently breached into S3, and that capability could be broadened.
Senior System Engineer at a healthcare company with 10,001+ employees
I suggest Nasuni improve their syslog forwarders to support TCP protocol, as it's more secure than UDP, which is plain text and not protected at all.

Flexibility and reliability have supported seamless data growth
I cannot think of anything to improve about Dell PowerScale (Isilon). The hardest challenge we have is due to how we've bought things over time. The way that we moved to the PowerEdge platform for the newer systems creates a scale problem as I still buy the older style systems, which are more dense storage. They're different chassis, so the problem we run into in the data center is the depth of the actual equipment. The newer equipment, if we buy an FX910 or a 900, it's a lot shorter in scale than if I buy an 83,000, which is much bigger. This makes it more complicated for deployment.

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…
