Configuring COMSTAR to Provide Local iSCSI Storage

Oracle Solaris 11 introduced two storage capabilities that I wasn't aware of until Oracle ACE Alexandre Borges brought them to my attention.

A Solaris 11 system can serve as an iSCSI target that offers storage to other machines, or as an iSCSI initiator to access the storage offered by another iSCSI target. This capability is a real advantage, because any storage offered through the iSCSI protocol is available to an iSCSI initiator as local storage, without the need to use expensive technologies such as Fibre Channel (FC).

Solaris provides this service through a framework named Common Multiprotocol SCSI TARget (COMSTAR). Alexandre Borges shows you how to use it:

Tech Article: Using COMSTAR and ZFS to Configure a Virtualized Storage Environment

How to use COMSTAR to provide local iSCSI storage for any service that runs in Windows, Linux, or Mac OS. It also shows you how to configure authentication using the Challenge Handshake Authentication Protocol (CHAP) to secure the iSCSI storage against forbidden access. Part 1 of a series about ZFS.

Exploring Installation Options and User Roles in Oracle Solaris 11

Part 1 of a two-part series that describes how Alexandre installed Oracle Solaris 11 and explored its new packaging system and the way it handles roles, networking, and services. This article focuses first on exploring Oracle Solaris 11 without the need to install it, and then actually installing it on your system.
