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 defined by the Media Access Control (MAC) address. MAC addresses are required for Ethernet (LAN) communications.
  • Fibre Channel (FC) identity which is 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.
  • iSCSI identity which is defined by the iSCSI Qualified 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 configuration template that is used for deploying a server.
  • NOTE: A virtual I/O pool can be associated with one or more compute pools.
