Servers
Introduction
This chapter describes how to create, manage, and monitor servers. Defining a server
enables Storage Center to pass IO through the ports on that server. Once a server is
created, volumes can be mapped to it. Storage Center automatically recognizes FC IO
cards within the network to which is connected. iSCSI IO cards must be configured either
during setup or as they are added to the network. A remote Storage Center can act as a
server to a local Storage Center for Replication, as described in Remote Instant Replay on
page 327.
Servers can be organized into server folders either to make them easier to manage or as
a means to restrict access to servers, as described in Users and Groups on page 261.
Several servers can be combined into a Server Cluster. The Storage Center views the
Server Cluster as one server. Volumes can be mapped to the Server Cluster or to a server
that is a member of the cluster. Refer to Creating a Server Cluster on page 32
One server or server cluster can be the host of one or more virtual servers. Each virtual
server can have a different operating system. The Storage Center views each virtual server
as a separate entity. Volumes mapped to one virtual server are not mapped to other virtual
servers residing on the same server. Refer to Creating a Virtual Server on page 42.
Server Icons
