Question
A storage administrator receives reports of network delays when database software attempts to access the storage array. The virtual machines that host the database software are installed on different rack servers connected to the Cisco UCS Fabric Interconnect domain. The existing SAN switches are connected to the Fabric Interconnects using two 8 Gb port-channel interfaces to connect the storage array. The storage administrator has decided to deploy iSCSI storage with four 10 Gbps interfaces connected to the Cisco UCS Fabric Interconnects. Which deployment type resolves the problems with storage contention?
Options
- AiSCSI storage with Cisco UCS Fabric Interconnect in the virtual port-channel mode
- BiSCSI storage with Cisco UCS Fabric Interconnect using an appliance port
- CiSCSI storage appliance on Cisco UCS Fabric Interconnect uplink trunk port
- DiSCSI storage appliance on Cisco UCS Fabric Interconnect in the storage end-host mode

Explanation
Cisco UCS Fabric Interconnect supports different Ethernet port modes for connecting external storage, including "appliance port" mode. Appliance port mode is designed for connecting external storage devices such as iSCSI storage appliances. It allows the Fabric Interconnect to connect in a clear upstream manner, treating the external storage as a separate entity rather than as a server or host. This mode helps avoid traffic contention and ensures proper handling of iSCSI traffic paths, especially when replacing or supplementing existing SAN switch connections.
