Virtual Input-Output Pools
A virtual I/O pool is a collection of one or more virtual I/O identity types that are required for network communication. A virtual I/O
pool can contain a combination of any of the following virtual I/O identity types:
• Ethernet identity which is dened by the Media Access Control (MAC) address. MAC addresses are required for Ethernet (LAN)
communications.
• Fibre Channel (FC) identity which is dened 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.
• iSCSI identity which is dened by the iSCSI Qualied Name (IQN). IQN identities are required to support boot-from-SAN using
the iSCSI protocol.
OpenManage Essentials utilizes the virtual I/O pools to automatically assign virtual I/O identities to the device conguration template
that is used for deploying a server.
NOTE: A virtual I/O pool can be associated with one or more compute pools.

Creating a Virtual Input-Output Pool
You can create a virtual I/O pool that contains one or more virtual I/O identity types.
To create a pool of virtual I/O identity types:
1. Click Deployment.
The Deployment Portal is displayed.
2. Perform one of the following:
• On the left pane, under Common Tasks, click Create Virtual I/O Pool.
• On the left pane, under Virtual I/O Pools, right-click Virtual I/O Pools → Create Virtual I/O Pool.
The Create Virtual I/O Pool wizard is displayed.
3. On the Name and Description page, type a unique name for the virtual I/O pool and an appropriate description, and then click
Next.
4. On the Ethernet Identities page, perform one of the following:
NOTE: If you do not want to include MAC addresses in the virtual I/O pool, clear the Include MAC addresses in this
pool option, and then click Next.
a. To specify the start address and the number of identities, perform the following:
1. In the Specify the start address box, type the start address that you want to predene in the MAC addresses that will
be generated.
NOTE: The input address range (start address + number of identities) is validated against the existing
address ranges for overlap when you are creating or editing a virtual I/O pool. The number of identities
requested cannot be guaranteed in case the requested address range is overlapping with an existing virtual
I/O pool address range.
2. In the Number of Identities box, type the identity values that you want to dene, and then click Next.
