You are asked whether the redundancy and bandwidth of the Remote Copy setup can be improved while retaining the current host-connectivity resources. What action is appropriate to meet the customer’s request?

  • A Install additional four port 32/64Gb FC adapter to slot 1 and use ports 0:1:3 and 1:1:3.
  • B Utilize ports 0:4:3 and 1:4:3 as additional ports for RCIP.
  • C Install additional four port 10/25Gb ethernet adapter to slot 2 and use ports 0:2:3 and 1:2:3.
  • D Utilize ports 0:4:1 and 1:4:1 as additional ports for RCIP.
Explanation

Slot 4 ports 3 and 4 are dedicated 10/25Gb Ethernet ports for RCIP, while slot 4 ports 1 and 2 are dedicated iSCSI ports. Configuring ports 0:4:3 and 1:4:3 as additional RCIP interfaces adds a second Remote Copy IP link on each controller node, improving bandwidth and redundancy without changing the existing host connectivity. HPE supports up to four RCIP links per node.
