A pair of SAN-attached servers will be clustered using host clustering, which of the following should the storage administrator do to support that configuration?

The correct answer is D. Shared volumes should be mapped to both servers via multiple storage interfaces.. To support host clustering with SAN-attached servers, shared volumes must be mapped to both servers, and this should be done via multiple storage interfaces to ensure high availability and fault tolerance.

Question

A pair of SAN-attached servers will be clustered using host clustering, which of the following should the storage administrator do to support that configuration?

Options

  • AVolumes should be mapped to one server and then the second server will provide redundancy
  • BShared volumes should be mapped to both servers via a single storage interface.
  • CStorage volumes from separate storage arrays should be mapped to each server via separate
  • DShared volumes should be mapped to both servers via multiple storage interfaces.

Why each option

To support host clustering with SAN-attached servers, shared volumes must be mapped to both servers, and this should be done via multiple storage interfaces to ensure high availability and fault tolerance.

AVolumes should be mapped to one server and then the second server will provide redundancy

Mapping volumes to only one server prevents the other server from accessing the shared data directly, making a host cluster setup impossible.

BShared volumes should be mapped to both servers via a single storage interface.

Mapping shared volumes via a single storage interface creates a single point of failure, undermining the redundancy and high availability goals of a cluster.

CStorage volumes from separate storage arrays should be mapped to each server via separate

Mapping storage volumes from separate storage arrays to each server means the servers are not accessing the *same* shared data, which is fundamental for host clustering.

DShared volumes should be mapped to both servers via multiple storage interfaces.Correct

For host clustering, all servers in the cluster must have simultaneous access to the same shared storage volumes. Mapping these shared volumes to both servers through multiple, redundant storage interfaces (e.g., dual HBAs and multiple SAN paths) ensures fault tolerance and high availability, critical for clustered environments.
