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.

HPE BladeSystem is a brand of blade server, from Hewlett-Packard Enterprise. HPE blades include the ProLiant BL series and the ProLiant WS series.
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.

All nodes can be managed centrally through the ILO interface. Users and services alike benefit from the lightning-fast response time. Enable service continuity during VM migration between nodes. The purchase of a blade system is something we endorse as a viable alternative for your business. In order for the convergent system to work, the architecture can be adapted to accommodate new devices, and by applying new modules, both the technology and the system's responsiveness to demands for high availability can be enhanced.

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 small form factor of a blade server cannot accommodate expansion cards.
Shared infrastructure, like the interconnects, means a larger fault domain.
Firmware updates can be disruptive and administrators should pay close attention to firmware recipes and bundles to ensure compatibility between components.

We do not intend to make new investments in HPE BladeSystem as it is in the end-of-life phase and we have continued with the new HPE Synergy environment. It is therefore not a process of discarding, but of evolution. This environment will possibly continue to be used in the institution, but for less critical purposes and more related to the development of new solutions.

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.

It's been said that BladeSystem is very similar to the UCS B-Series. While the network fabric features of the UCS B-Series outshine those of the BladeSystem, HPE has created extensive orchestration within HPE OneView to provide feature parity with and even surpass those of the UCS B-Series. The fundamental distinction between the two is whether the focus is on the computing (BladeSystem) or the fabric (UCS). In contrast to UCS's tight fabric integration, BladeSystem's centralized focus on servers simplifies administration.
