Which two performance metrics can be used to trigger scaling actions In Autoscaling?

On Oracle Cloud Infrastructure (OCI), a customer wants to build a3TB filesystem for high IOPS workloads (like relational databases, small files, etc).
Which action provides the highest IOPS using OCI block volumes for storage?

You are building a RDMA cluster on a private network with 10000 cores. What CIDR will work in theVCN:
172.16.0.0/16?

A file system is built using two BM.Standard2.52Compute shapes for File servers. On each file server, one 25 Gbps (3125 MB/s) NIC/network card is used to connect to 10 Block Volumes of 1TB each (max. 480MB/s per volume) and other 25 Gbps NIC Is used for sending/receiving data to/from client nodes.
Filesystem client instances which mount the file system are provisioned using VM.Standard2.16 Compute shapes. (Network bandwidth: l6.4Gbps(2050 MB/s)) What is the max aggregate IO throughput (theoretical) of the file system?

What two types of workloads can benefit from Cluster Networking (RDMA)?
