Chapter 1: Introduction
This document provides information on how to install and configure the Leostream™ Connection Broker for
use with Red Hat Enterprise Virtualization for Desktops. See the associated sections of the complete
Connection Broker Administrator’s Guide for more information pertaining to each step.
Leostream™ Components
The Leostream Connection Broker consists of the following four components.
Connection Broker: The Connection Broker is the central management layer for configuring your
deployment, including: inventorying desktops, applications, printers, and other resources; assigning
these resources to users; defining the end-user experience. Connection Broker version 7.5 is
available as a virtual appliance that installs directly on to the Red Hat Enterprise Virtualization
Hypervisor, and can be upgraded to the most recent Connection Broker release.
Leostream Agent: When installed on the remote desktops, the Leostream Agent provides the
Connection Broker with insight into the connection status of remote users. The Leostream Agent
also performs functions related to the Leostream printing and USB management features. Although
optional, the Leostream Agent is a critical component when scaling out deployments to a large
number of end users. For users connecting to desktops using the SPICE protocol, the Leostream
Agent can also be used to provide single sign-on to Microsoft® Windows® desktops.
Leostream Connect: Leostream Connect is a software client provided by Leostream that allows
users to log into desktops from fat or thin clients. Using Leostream Connect, you can repurpose
existing fat desktops and laptops, lowering the cost of VDI deployments. Some thin clients provide
built-in Leostream Connect clients. Leostream Connect is required for users connecting to desktops
using the SPICE protocol.
Database: By default, the Connection Broker stores all information in an internal database. A typical
installation requires one Gbyte of disk space for the internal database. Large scale deployments
that require Connection Broker clusters must use an external Microsoft SQL Server® 2012 or 2014
database.
What is the Connection Broker?
A connection broker lies at the heart of any VDI deployment, and is the key component for assigning
resources to end users. The Leostream Connection Broker runs as a virtual appliance within the Red Hat
Enterprise Virtualization Hypervisor, making it easy to install, maintain, and update.
The Connection Broker provides end users with consistent, reliable access to data and desktops from a wide
range of fat and thin clients. The Connection Broker also allows you to manage:
Desktop usage, to optimize resource and power consumption
USB device redirection, to ensure data security
