Testing oracle I/O performance on 2 node SCale IO for proof of concept

Hello,

My organization is doing a proof of concept for evaluating Scale IO for database workloads   . Here is the setup for  POC.

All three components  (MDM,SDS and SDC) have same specs

We are using 1 MDM  server , 2 SDS servers and 1 SDC server

The SDS servers each has 160 GB HDD SATA DISK , so we will be getting an aggregate of  320 GB for Storage pool.

Which oracle I/O performance testing tools. should we use , ORION or SLOB  for this poc ?

The attachment provides  the basic spec of node.

Thanks,

Amjad
