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.

QoreStor facilitates the adoption of most storage types, uniquely including cloud object storage like native object storage. QoreStor’s advanced compression and deduplication algorithms aim to slash storage requirements and costs anywhere QoreStor is deployed, even in the cloud. QoreStor includes ransomware protection capabilities to protect backup data.
QoreStor replaces the Quest DR Series the former Dell / Quest backup and recovery solution, featuring data deduplication.
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.

The product can be run on-premises or in the cloud. It is a fantastic option to reduce the size and storage requirements of backup jobs. If your backup system can already produce a reliable reduction in storage up to 75% then I would say the QoreStor appliance would be irrelevant in your case. It does not perform backups itself. It is simply an extra step to reduce size, encrypt and offload backups to the cloud. this reduces the load on a backup system to handle other tasks while the QoreStor takes over.

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.

The support team is the main reason I am sticking to Quest/KACE products. They are stellar to work with and always responsive when I need help. The team listens to the user's recommendations for added features and tends to add the ones that really have merit. Support is everything when it comes to working with such a company

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.

When I evaluated the Dell system it was an entirely new server on-site, with licensed levels of inlocking the storage it had on board. For a smaller organization, the Dell system was not cost-effective with a large upfront payment, and additional hardware to manage on-site. The QoreStor system was a virtual machine that could pop into my current system and just use allocated storage already in place. In addition, the upfront cost was dramatically less than the Dell option and no additional hardware
