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?

Your customer has upgraded to faster tape technology and the backup is now taking longer. No other changes have been made. What is a possible cause of the performance degradation?

A two fabric merge has failed leaving you with segmented fabrics. Which could be the the cause of the segmented fabrics?

An application administrator seeks to improve the I/O performance of the server’s SAN-attached storage. Which HBA parameter setting change can affect the performance?

What enables a virtual machine to have a unique World Wide Port Name?

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

A customer has a database server that processes a great deal of data very quickly. They have identified a bottleneck in the storage subsystem and requested a change to the RAID configuration. How would you configure the new RAID group? (Choose two.)

Two servers have been connected to a SAN with redundant fabrics and the zone configuration needs to be changed. How can you safely change the zone configuration?

You have a single fabric with four servers connecting to an edge switch in a core edge configuration with single 2Gb/s ISLs to the core. Each server has an average throughput requirement of 40MB/s. Under which circumstance would you need to add a second ISL?

What two (2) benefits does SCSI Command Tag Queueing provide? (Choose two.)
