Adapter Fault-tolerance Menlo and Palo-based mezz cards can automatically get rerouted to another IOM in the event of a failure of the active path if configured to do so: A given ethernet vnic uses one and only one active path at any given time (either through Switch A or B, but not both at the same time) 31

Backplane-based adapter failover As mentioned before, the chassis backplane provides Menlo and Palo adapters with both an active and a standby path for Ethernet vnics Here s a logical representation of a profile using the two vnics provided by Menlo: IOM 1 vnic 1 standby path vnic 0 active vnic 0 standby path Server 1 IOM 2 vnic 1 active 32

Linking a vnic and a pin-group When creating a vnic, you can attach it to any existing pin-group 35

Traffic Engineering vnics can be pinned to specific switches when created (with configurable failover to other switch) Depending on requirements, vnics could be pinned to one switch or distributed evenly vnic-1 vnic-2 FEX-1 2 Fabric Extenders in chassis, each with 1 link to the switch. vnic-3 Switch-1 Blade-1, Palo-1 Palo NIC with 3 vnics vnics in System Class C pinned to one switch vnic-1 Blade-2, Palo-1 vnic-2 2 switches, both with 1 connection to each FEX vnic-3 FEX-2 Class-A Class-B Class-C Switch-2 36

EHM: No locally attached devices In end-host mode there is no MAC learning on network ports. Servers are pinned to network ports directly.as such, attaching a device (NAS, etc.) locally does not work! NAS FC 39

Reverting back to Switching Mode 40

Why Switch Mode? Locally attaching devices to FI ports becomes an option Keep in mind though that with the FCS release only 10GE connections are available The Aptos release will allow ports to operate in 1GE mode User familiarity with well-known STP mode of operation Provides a somewhat easier transition to UCS to certain customers 41

Port Profiles in UCS vnics are dynamic and malleable Port Profiles in UCS capture several vnic properties vnic Type Network Configuration QoS Parameters Example Profile Name HR Type VLAN 5 Rate Ethernet 10 Mbits Security Policies* Port Profiles can be exported to VC and used as Port Groups in UCS DVS * Post-FCS 42
