In the previous chapter, you learned about the Fibre Channel storage architecture. Now you will learn how to troubleshoot problems with FC SAN. In FC SAN, general problems occur in storage throughput. The general problems that can occur include storage throughput and latency in read and write operations. Storage stack, follow the stack to troubleshoot the latency, and so on.

The ESX architecture has lots of components. Here, we will see the physical components at the bottom: CPU, memory, networking, and storage devices. Then, on the upper layer, we have the ESXi VMkernel software layer, and in it, we have various components, such as the scheduler that schedules the VMs on the physical CPUs, and the memory allocator that divides the physical memory and allocates it to the VMs. We also have various drivers for connecting to physical devices, such as networking and storage drivers. The most important part of the VMkernel is the monitor...
