The most valuable feature for us is the combining of HA and SnapMirror.This solution provides us with easy management and great vendor support.One of the most valuable features offered is double-parity RAID, which guarantees that your data will stay intact. We're also able to provision storage and monitor which ones are really consuming storage.It is good to have a unified storage where you can have block and file level protocols.The initial setup was so straightforward. It was well-documented.It is very flexible. It integrates well with the public cloud and other components, so everything can be API driven. Therefore, it is very easy to automate it.Using the built-in Snapshots and SnapMirror technology, we were able to have better working data protection locally and off-site.The storage efficiency provided a maximum savings in our storage utilization.

The solution isn't suitable for small environments or small customers.

Currently, the newest release is not HCI friendly.Dedicated storage efficiency accelerators could improve the overall performance of the system.I would like to see less latency and higher IOPS.It lacks automatic tiering, When you use data, some of it goes cold. It is not hot data, so the system should automatically move that data to the SATA, while the hot data is kept on tier-one, the SaaS or SSD drives.The only downside is in ease in management; it is not easy to use.It's not a cheap system. It is very expensive. The pricing has been ridiculous every time that we had to renew the support.We would like to have further integration with some backup products. They have some of them already, but there could be more.The AutoSupport could be improved to be more proactive in certain cases.

Isilon is Scale-out storage, while NetApp is Active-Standby storage.

Regarding the performance issue based on the field engineer’s experience, Isilon is better than NetApp in case of a huge amount of io, while NetApp is better than Isilon in case of a medium amount of IO.

I think you need rewiew more than only performance or capacity, I have installed both machines, Netapp FASS have many options Hibrid or only objects, in Netapp Objects is StorageGrid where can obtain 720 TB in SG5760 but you can select SG6060 or SG5712 and Isilon is similar you have many options where could be ALL FLASH or SATA but Isilon is only NAS, and Isilon have many reference too, 8 reference F810 have 924 TB and up 250.000 I/Ops.

Actually I recommend one arquitecture where no focus only in one purpose, Scale up or Scale out all vendors have different alternatives and deppend the machine offer more I/O or Capacity, Midrange and High end, I don´t like Isilon because is only for NAS I dont like Hibrid or Unified Machines as FAS or VNX, I need to know which is the prupose for have a NAS because actually I can have a Storage for all protocols no only to CIFS and NFS and with prices cheaper than NAS, in conclusion I don´t like one Storage for NAS other for SAN other for Virtualization... Is better only one Storage where I can do it all, It reduce TCO.

My recommendation is to take a close look at our CS Concerto Scale-Out Cluster system.
