A production cluster is attached to redundant disk fabrics and a tape fabric. 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 HBAs single initiator zoned to sixteen storage ports on one storage
subsystem. The tape fabric includes one connection to each server and connections to four (4) 1Gb
FC to SCSI gateways connected to ten (10) LTO II (35MB/s) tape drives. The standby cluster member
performs multi-threaded 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.
FC to SCSI Gateway
