Hello,

I have an Emc Unity 300 controller (12x7.68 SSD 4x16 base + 2 extra 16g I/O modules) and I use 2 16 SAN switches.

A and B controllers are connected to SAN-A and SAN-B with 4 Om4 16 Gb FC cables each. There are 3 hosts, and each host is connected to SAN-A and SAN-B via 16G FC.

When I initiate a simultaneous disk read/write speed test from 2 hosts, the total speed does not exceed 2.4GB/s.

It seems as though the total speed is limited to 16G. I am using ESX8 as the operating system. What could be causing this issue?
