In the previous chapter, we discussed the details of FC storage troubleshooting. Now we will focus on iSCSI storage, so let's learn more about the iSCSI storage architecture. iSCSI, which stands for Internet Small Computer System Interface, works on top of the Transport Control Protocol (TCP) and allows the SCSI command to be sent from end to end over local area networks (LANs), wide area networks (WANs), or the Internet. It works by transporting block-level data between an iSCSI Initiator on a server and an iSCSI target on a storage device. The iSCSI protocol encapsulates SCSI commands and assembles the data in packets for the TCP/IP layer. Packets are sent over the network using a point-to-point connection. Upon arrival, the iSCSI protocol disassembles the packets, separating the SCSI commands so that the OS will see the storage as a local SCSI device that can be formatted as usual. Today, some of iSCSI's popularity in small- to medium-size businesses...

Overview of this book
<p>vSphere Storage is one of the three main infrastructure components of a vSphere deployment (Compute, Storage, and Network).</p>
<p>Mastering VMware vSphere Storage begins with an insightful introduction to virtualization and creating your own virtual machines. We then talk about VMware vCenter Server and virtual machine management, as well as managing vSphere 5 using vSphere Management Assistant (vMA) and esxcli and vmware-cmd commands. We then swiftly move on to a very interesting topic, reviewing the vSphere performance and troubleshooting methodology. We then configure VM storage profiles, Storage DRS, and Storage I/O control. More significantly, we will troubleshoot and analyze storage using the VMware CLI and learn how to configure iSCSI storage.</p>
<p>By the end of the book, you will be able to identify useful information to make virtual machine and virtual data center design decisions.</p>
