Users Guide

uniquely identify a server on a network and also determine how the server communicates with a network resource using a
specific protocol. Using OpenManage Enterprise, you can automatically generate and assign virtual identity attributes to the I/O
interfaces of a server.
Servers deployed by using a device deployment template that contains virtual I/O identities are known as 'stateless.' Stateless
deployments enable you to create a server environment that is dynamic and flexible. For example, deploying a server with virtual
I/O identities in a boot-from-SAN environment enables you to quickly do the following:
● Replace a failing or failed server by moving the I/O identity of the server to another spare server.
● Deploy additional servers to increase the computing capability during high workload.
The OpenManage Enteprise > Configuration > Identity Poolspage allows you to create, edit, delete, or export virtual I/O
pools.
NOTE:
● To perform any tasks on OpenManage Enterprise, you must have necessary role-based user privileges and scope-based
operational access to the devices. Role and scope based access control in OpenManage Enterprise on page 15
● Scope based restrictions don't apply to identity pools, therefore, all identify pools can viewed and used by all user types.
However, once the identities are assigned by a device manager, then only those identities can be viewed and used by
that device manager.
Create Identity Pool - Pool Information
Identity pools are used for template-based deployment on servers to virtualize the network identity for the following:
● Ethernet
● iSCSI
● Fibre Channel over Ethernet (FCoE)
● Fibre Channel (FC)
You can create a maximum of 5000 identity pools in each of these categories.
The server deployment process fetches the next available identity from the pool and uses while providing a server from the
template description. You can then migrate the profile from one server to another without losing access to the network or
storage resources in your environment.
You can edit the number of entries in the pool. However, you cannot reduce the number of entries less than those assigned or
reserved. You can also delete the entries that are not assigned or reserved.
Identity pools
An identity pool is a collection of one or more virtual identity types that are required for network communication. An identity
pool can contain a combination of any of the following virtual identity types:
● Ethernet identities
The Identities which are defined by the Media Access Control (MAC) address. MAC addresses are required for Ethernet
(LAN) communications.
● iSCSI identities
The Identities which are defined by the iSCSI Qualified Name (IQN). IQN identities are required to support boot-from-SAN by
using the iSCSI protocol.
● Fibre Channel (FC) identities
The Identities which are defined by the World Wide Node Name (WWNN) and World Wide Port Name (WWPN). A WWNN
identity is assigned to a node (device) in an FC fabric and may be shared by some or all ports of a device. A WWPN identity
is assigned to each port in an FC fabric and is unique to each port. WWNN and WWPN identities are required to support
boot-from-SAN and for data access using FC and Fibre Channel over Ethernet (FCoE) protocols.
● Fibre Channel over Ethernet (FCoE) identities
Identities that provide a unique virtual identity for FCoE operations. These identities are defined by both MAC address and
the FC addresses (that is WWNN and WWPN). WWNN and WWPN identities are required to support boot-from-SAN and for
data access using FC and Fibre Channel over Ethernet (FCoE) protocols.
