iSCSI

iSCSI is an evolution of the SCSI protocol, which allows SCSI commands to be sent over a network. It allows two hosts to negotiate and then exchange SCSI commands using IP networks. The result is that a remote device with iSCSI capabilities can be seen to be a local disk drive but the commands and data for that device are being sent over the network rather than down a cable in the machine.

There are two parties involved in iSCSI, the iSCSI target and the iSCSI initiator.

An iSCSI target acts as a remote SCSI disk and it can receive SCSI commands and apply them to a local disk, this similar to a 'server'. An iSCSI initiator connects to an iSCSI target and uses the designated disk as a local disk. This is akin to a 'client'.

iSCSI disks behave in exactly the same way as local disks in that you can only have one computer controlling that disk. Therefore, it is important to ensure that only one iSCSI initiator uses any particular iSCSI target. If two (or more) iSCSI initiators use an iSCSI target, there will be data corruption.

Learning FreeNAS: Configure and manage a network attached storage solution

FreeNAS is free software that turns a PC into a Network Attached Storage (NAS) server. It supports client connections from Microsoft Windows, Apple OS X, Linux, and FreeBSD. It has a web interface for administration and includes support for RAID (0, 1, 5), iSCSI, drive encryption, and UPnP. Based on FreeBSD, it has modest system requirements but is scalable for the enterprise.

This book will show you how to work with FreeNAS and set it up for your needs. You will learn how to configure and administer a FreeNAS server in a variety of networking scenarios. You will also learn how to plan and implement RAID on the server as well as how to use Storage Area Network technologies like iSCSI. The standard FreeNAS documentation walks you through the basic configuration, but this book will tell you exactly what you should do to plan, work, and deploy FreeNAS. This book has a comprehensive troubleshooting section that will point you in the right direction whenever you need help.
