Actual exam question from Cisco's 300-610
Question #: 128
Topic #: 1
[All 300-610 Questions]

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?

  • A. iSCSI storage with Cisco UCS Fabric Interconnect in the virtual port-channel mode
  • B. iSCSI storage with Cisco UCS Fabric Interconnect using an appliance port
  • C. iSCSI storage appliance on Cisco UCS Fabric Interconnect uplink trunk port
  • D. iSCSI storage appliance on Cisco UCS Fabric Interconnect in the storage end-host mode

How about vpc mode, A? Why can't this be the answer? Virtual Port-Channel (vPC) mode on Cisco UCS Fabric Interconnects allows multiple physical links (in this case, the four 10 Gbps interfaces) to be aggregated and logically appear as a single connection to the storage appliance. This increases bandwidth and provides redundancy by allowing multiple physical paths to be used for iSCSI traffic without the complexity of Spanning Tree Protocol (STP) blocking certain links. vPC enables load balancing and failover across multiple paths, addressing issues related to storage contention and network delays. The increased bandwidth and path redundancy will alleviate contention issues by ensuring there is enough capacity and reliability for storage traffic between the UCS servers and the iSCSI storage.
