Chapter 10. Setting Up iSCSI, NFS, and
IdM Directory Services for RHEV
In this chapter, we are going to discuss setting up various storage services and directory
services to use with Red Hat Enterprise Virtualization. Generally, in any IT enterprise, a
storage type of either
Network Attached Storage
(
NAS
), iSCSI, or Fiber Channel is used
to store critical application data and virtual machine images of the virtual infrastructure.
From the point of view of directory services, they use either Active Directory Services in a
Windows-dominated infrastructure and
Identity Management
(
IdM
) for Red Hat or
OpenLDAP in a Linux-based infrastructure. Though you can use the local storage of the
host to store virtual machine images for noncritical workloads with limited virtualization
functionalities, such as the live migration of a virtual machine from one host to another,
you can also turn your Red Hat Enterprise Linux server to
Network Attached Storage
(
NAS
) server, such as
Network File Server
(
NFS
) or iSCSI Server. Moreover, you can
configure and set up the Red Hat IdM software to make the server act as a directory server
for your Linux environment.
In this chapter, we are going to learn the following topics:
• How to set up iSCSI for the data domain
• How to set up NFS for the export domain
• How to install and configure IdM
In the forthcoming sections of the topic, we are going to set up and configure NAS services
on RHEL, such as iSCSI and NFS, for RHEV data and the export storage domain. We will
also learn how to install and set up the IdM server for directory services to be attached with
RHEV for user and group management.
