A file system is built using two BM.Standard2.52 Compute 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.
File system 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?

A. 3125 MB/s

B. 9600 MB/s

C. 4800 MB/s

D. 6250 MB/s
