What are the benefits of an ISCSI hardware initiator over a software-based one? Choose two.
  1. Hardware initiators are significantly cheaper.
  2. Hardware initiators reduce CPU load on the ESX/i host.
  3. Hardware initiators are supported by VMware, whereas software initiators are not.
  4. Hardware initiators reduce memory load on the ESX/i host.
Explanation
Answer: B and D - An ISCSI hardware initiator reduces CPU and memory load on an ESX/i host because it offloads the entire TCP/IP and SCSI stack to the adapter. These benefits, however, may or may not be relevant for modern-day processors.
