Maintaining a persistentconnection between host and storage, ESXi must support multipathing. Which of the following statements is incorrect regarding multipathing for VMware vSphere 5.5?

A.

In addition to path failover, multipathing also provides load balancing. Load balancing is the process of distributing I / O load across multiple physical paths.

B.

In the event of a path failover, the virtual machine I / O delays Nintendo pump by 60s.

C.

If the failover takes a long time to complete, the windows virtual machine may interruptthe I / O and eventually fail. To avoid this, set the windows virtual machine timeout to at least 30 seconds.

D.

When coordinating vmware NMP and any installed third-party MPP, the PSA (Pluggable Storage Architecture) performs load and unload multipathingplug-ins and handles physical path discovery and removal.

In a Huawei OceanStor 18000 the engine, SVP, diskenclosure, and PCIe switch interconnections must be in accordance with certain rules and order. Which of the following statement is incorrect?

A.

The SVP needs to connect multiple engines through two PCI-e switches, and each engine's controller needs to be connected to a PCIe switch to ensure that the link redundancy provides reliability.

B.

When the control plane is connected to the network, when the engine and the PCIe switch are interconnected, the port P0 of the A3 slot and the PCI switch PCI port canbe used pick up.

C.

Huawei OceanStor 18000 can be used to install SAS interface modules and interconnect disk enclosures in slot 0 and slot 5 of the Huawei OceanStor 18000.
