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.

IBM Spectrum Accelerate is an enterprise software defined block storage solution.
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.

I recommend this product in cases when we have to Deploy scale-out storage grids in automated environments; it can be done in minutes rather than days. Another exciting point is the quality of service that it allows for establishing different performance tiers without a need for physical tiering. A point against, from my point of view, is connectivity because it only provides a connection by iscsi.

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.

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.
