What should be monitored to determine the root cause?
Five out of 4S servers using one particular enterprise storage system are experiencing
performance degradation during normal working hours. All 48 servers have similar workload
characteristics. There are multiple disk groups that make up your enterprise storage.
What should be monitored to determine the root cause?
What is a possible cause of the performance problem?
A customer in the medical services industry is having performance issues with the database that
maintains patient records. Recently the hospital expanded the SAN and added the fibre channel
directors in a core-edge topology which included moving the server from the core to the edge.
After determining the TCP/IP network is functioning correctly with no over-utilization of network
resources, the system administrator is attempting to determine what possible causes there are for
the degradation. What is a possible cause of the performance problem?

What is the amount of permissible downtown per week?
A line of business (LOB) executive informs you that a new application requires 99.999% (five 9s)
of up-time from both planned and unplanned outages before a service level objective (SLO) will be
breached.
What is the amount of permissible downtown per week?
What is the most likely cause?
Infrastructure parameters include a small core edge design with all peripherals (disk and tape)
located in the core and all hosts connected to edge switches. Each host includes two HBAs, in
fabric A and B respectively, with all disks visible on both fabrics and tape devices divided between
fabrics. The tape devices are single initiator zoned to LTO II tape drives. You are recovering a 200
GB journaling file system, 70% utilized; spread over eight mirrored spindles using a 32K stripe
element. During recovery of one host, other hosts on the same edge report SCSI errors. What is
the most likely cause?
