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.

VMware vSAN is an enterprise-class storage virtualization software that provides a simple path to hyperconverged infrastructure (HCI) and multi cloud. VMware vSAN is no longer sold as a standalone product and is now available as a part of VMware Cloud Foundation.
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 is a must for enterprise & SMB segments as this gives a good value for money and the licensing policy is very well defined and cost effective for the feature set it provides. This is very well suited for organization which have multiple brand storage systems and would like to consolidate them all together, thus providing a huge storage capacity for the organizations data growth. The product becomes less appropriate in organization where they have single storage platform as the service provider would have the ability to consilidate all the storage systems. Hence this products may be under utilized.

VMware runs VSAN certification programs to make sure the OEM sells validated nodes. It helps customers to select appropriate certified ready nodes like Lenovo ThinkAgile VX which comes factory configured and easy to set up.
Hyperconverged solutions reduce real estate space and networking costs when compare with shared storage. The host overhead also less.
Supports All-Flash (SATA and NVMe SSDs) and Hybrid vSAN with HDD and SSD. So customers can choose cost-effective solutions appropriate to their workloads.
Supports different storage policies, RAID and duplication, and compression features and it makes a complete storage solution.

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.

We were a fairly early adopter of VMware vSAN and as such experienced several growing pains.
We experienced a few bugs that took a few software versions upgrades to go mostly away.
The biggest issue we had overall was with host drivers. Even with vSAN ready node compatible hosts, you have to be very careful that the drivers for NIC and RAID controllers are right.

Deploying and configuring VSAN is a relatively simple process for people that are already used to working in virtual environments, primarily for those that are familiar with vSphere. The compatibility of those two products is amazing. You shouldn't really encounter any issues and if you do, you surely did something wrong.

Support is (as always forVMware) top notch and easy to work with. The majority of computer companies are outsourcing their tech staff, and it seems they do as well. But their guys know the product well and are quick to respond to your ticket (if the severity is right!).

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.

Our VMware solution is built in-house for the organization's private application, we don't want to put our data on cloud premises. Also, vSAN is a cost-effective solution for our environment. We have done the POC with both products to understand the Flexibility, Management, and cost. After the successful POC, we have chosen the VMware vSAN.
