Dell Technologies presents Dell PowerScale (replacing EMC Isilon) as a scale-out NAS solution and server technology that provides the flexibility of a software-defined architecture with accelerated hardware innovations to harness the value of data.
Isilon Systems was acquired by EMC in 2010; some EMC Isilon NAS appliances are still available and supported under the PowerScale brand.

EMC Isilon Scale-Out NAS is well suited for larger files (greater the 128 Kb) and where you need to have everything in one common name space. Where it is less appropriate is for many small files (millions of files less than 128 Kb in size) - this causes the protection level to becoming mirroring, which will cost more space.
Well suited if you have a lot of data that doesn't need to be stored and read right away. I think even if you don't have much data, you can still use it for it's intended purpose to great effect, but think of it as the more data you have, the even better it will work. I don't think it would be particularly useful if you already have a slick file restore system in place and you don't need to store your data elsewhere with redundancy.
The management console is extremely simple and easy to navigate, making common tasks easy to do.
Our storage appliance is configured to snapshot data several times an hour, making the risk of data loss very low.
Data restores are very intuitive, and take seconds to initiate regardless of whether it is one file or 300GB of data. We have successfully restored many Gigs of data in minutes.
Some upgrades require the entire cluster to be rebooted simultaneously. In this day and age, that should not be necessary. This is my biggest disappointment with Isilon to date.
When using multiple storage pools you have to be very careful with your capacity management. Filling up one pool can cause an overflow of data to a pool that is less performance driven. Do not underestimate your capacities or you will find yourself in a tight spot.
Block size is almost always an issue with Isilon. It does not handle all types of data well. In many cases PACS and VNA data is best to be stored on a different storage platform that will utilize the capacity more efficiently that Isilon is capable of.
Deduplication seems to be less efficient on Isilon than on other platforms for similar types of data.
As I mentioned, the user interface is amazing and straight forward. It's very easy to learn how to configure and restore files. I would like a bit more reporting, especially in terms of live reporting and monitoring. The support is great when you have a question on how to do something, which helps with usability.
Again, it may have a little to do with the size and speed of your own environment, but we've been nothing but pleased with the speed of access of the files - even pulling old files from the cloud storage. Recovery of huge and many data files is a bit slow if you don't have the specs of the filer up to snuff.
Raw disk space vs. logical disk space ratio was significantly better on the Isilon. Fast cache using SSD drives for faster searching is available on the Isilon but not available on the Overland solution. Isilon solution included faster backend switching between nodes.
The technical support and escalation path for Nasuni is much more reliable and efficient. No getting transferred to various teams. Often times, the person who answers your call is able to resolve your issue. If they cannot, they get the case assigned to the appropriate engineer right away. Time to close has always been very good.
Dramatically reduced time spent managing our storage platform. Quotas and reporting tools take all the guesswork out of data growth. Updates are easy to deploy. Time freed up can be used for more user-facing activities that we consider more valuable to the organization.
The overall stability of the platform has been very good. We have been running on the same hardware for the past four years without any performance issues.
