The customer has an existing fabric switches installed from one manufacturer. They have decided to add a redundant fabric using switches from a different manufacturer. Interoperability is their main concern. What is important when considering interoperability in the SAN?

A. switch interoperability mode

B. HBA firmware/driver code

C. zone naming convention

D. virtualization engine

A customer has deployed redundant switched fabrics in a HA environment which also includes nonHA, singleattached test servers. A new project requires additional connectivity for new HA servers to be placed into production, but there are not enough free ports avalable in one of the existing fabrics to complete the HA deployment. Which option would allow for the addition of the new hosts while maintaining the redundant infrastructure at least cost?

A. Add a new switch to the problem fabric to increase available ports on the switches.

B. Add a new switch to both fabrics to increase available ports on the switches.

C. Add ISL's between the existing fabrics to leverage all available ports on the switches.

D. Cascade the existing switches into a new director class switch and add the hosts to the director.

A production cluster is attached to redundant disk fabrics and a tape fabric. Each fabric is contained within a single switch. Each cluster member has access to twelve (12) TB of RAID 5 production storage and twelve (12) TB of RAID 0 local replica accessed through eight (8) HBAs single initiator zoned to sixteen

(16)

storage ports on one storage subsystem. The tape fabric includes one (1) connection to each server and direct connections to ten (10) LTO II (35MB/s) tape drives. The standby cluster member performs multithreaded backups using the local replica. All HBAs and ports are 2Gb/s. If the recovery time is equal to backup time, where is the bottleneck?

A.

tape HBA

B.

disk HBAs

C.

tape drives

D.

subsystem contention

Which set of SCSI components are required to support SCSI command tag queueing?

A. adapter, adapter driver, device, device driver

B. adapter, device, device driver

C. adapter, device driver, controller, controller firmware

D. device, device driver

What is the next step after making a backup of your fabric configuration before making changes to the active zone set?

A. Create a new zones

B. Activate change tracking

C. Disable the active zone set

D. Copy the active zone set
