In the previous chapter, we discussed storage troubleshooting by different types of common tools in detail. Now we will focus on Fibre Channel storage. So, let's learn more about the FC storage architecture. A Fibre Channel storage area network is a specialized high-speed network that connects computer systems or host servers to high-performance storage subsystems. The SAN's components include host bus adapters (HBAs) in the host servers, switches that help route storage traffic, cables, storage processors (SPs), and storage disk arrays .A SAN topology with at least one switch present in the network forms a SAN fabric. To transfer traffic from host servers to shared storage, the SAN uses the FC protocol, which packages SCSI commands into Fibre Channel frames.
In the vSphere environment, the FC SAN—as shown in the following diagram—includes virtual machines, ISO images, and templates in a data store that supports 16 Gbps throughput:
