All-in-one configuration (Figure 1)
In an all-in-one configuration, filtering
and management take place on the
same system.
High availability deployment (Figure 2)
For load balancing and redundancy, split
mode enables organizations to filter at
the network perimeter while providing
centralized control. Administrators can
easily synchronize Dell SonicWALL Email
Security across multiple LDAP servers in
distributed and hosted environments for
scalable deployment.

Dell SonicWALL Email Security
deployments
The highly flexible architecture of Dell
SonicWALL Email Security enables
deployments in organizations that
require a highly scalable, redundant and
distributed email protection solution that
can be centrally managed. Dell SonicWALL
Email Security can be deployed in either
all-in-one (Figure 1) or split mode
(Figure 2).
In split mode systems may be configured
as a remote analyzer or a control center.
In a typical split-mode setup, one or more
remote analyzers is connected to a
control center: The remote analyzer
receives email from one or more domains
and applies connection management,
email filtering (anti-spam, anti-phishing
and anti-virus) and advanced policy
techniques to deliver benign email to the
downstream email server. The control
center centrally manages all remote
analyzers and collects and stores junk
email from the remote analyzers.
Centralized management includes
reporting and monitoring of
all related systems. This paradigm allows
the solution to cost-eectively scale and
protect both inbound and outbound email
for growing organizations. Using Dell
SonicWALL Email Security Virtual
Appliances, split mode can be fully
deployed on one or multiple servers for
optimal eciencies of scale.
