Storage Network Design

A network architect is designing an iSCSI-based storage area network solution. The iSCSI datastore must provide high availability, minimal downtime, and no single point of failure. I/O must fail over to alternate paths based on SCSI sense codes, without depending on network failures.

Which feature must be deployed to satisfy these requirements?

  • A hardware-based flow control
  • B port security
  • C iSCSI multipath
  • D NIC teaming
Explanation

iSCSI multipathing creates redundant storage paths to a SCSI logical unit and applies storage multipathing policies for path failover. This allows I/O to move to an alternate path in response to SCSI-level path conditions, rather than relying solely on detection of a network failure.
