Correct answer: That the total amperage draw of the fully populated VSP E790 system does not exceed the capacity of the PDUs and the branch circuit.

The most critical power consideration is ensuring the total power draw (amperage) of the storage system does not overload the PDUs or the circuit breaker. While phase separation is a best practice for redundancy, exceeding the total capacity is a primary safety and operational risk that must be verified first. The number of outlets and network port availability are secondary concerns compared to the fundamental power capacity.

Correct answer: Alert Notification Settings

The Alert Notification Settings section of the initial configuration process is specifically designed for configuring methods of sending system alerts, including SNMP traps, email notifications, and Syslog forwarding. The installer must enter the IP address and port of the customer's Syslog server in this section. Network Settings are for the system's own IP, Date and Time is for NTP, and User Accounts is for local access.

Correct answer: The installer did not formally clear the fault in the maintenance utility after replacing the hardware.

For many component replacements in VSP systems, especially those related to memory or processing, the fault status must be manually cleared using the maintenance utility (like Storage Navigator) after the physical replacement is complete. The system does not always automatically clear the historical alert. This action confirms the repair and resets the component's status to normal. Rebooting the controller is a drastic step and usually not required.

Correct answer: RAID-1 (1D+1D) across multiple pairs to create a mirrored pool.

For high-transaction database applications, write performance is critical. RAID-1 (mirroring) provides the best write performance because it does not have the write penalty associated with calculating and writing parity bits like RAID-5 and RAID-6 do. While it has a 50% capacity overhead, it meets the primary requirement of maximizing write performance for the specified workload. RAID-5 and RAID-6 are better suited for read-intensive or capacity-focused applications.

Correct answers: It provides the primary web-based GUI (Storage Navigator) for managing the storage system.; It runs on an out-of-band management network, separate from host data traffic.

Correct answers: Verify the health of the system and ensure there are no existing hardware faults or alerts.; Save the current system configuration data to an external location.

Correct answer: False

VSP E-series systems support non-disruptive, online hardware upgrades, including the addition of new drive enclosures. The procedure involves carefully connecting the SAS cables to the existing back-end chain and then powering on the new enclosure. The system controllers will automatically detect the new hardware without requiring a system-wide outage.

Correct answer: False

The system serial number is factory-set and embedded in the system's hardware/firmware. It is not something that an installer sets or modifies using the System Option Mode (SOM) during a new installation. SOM is used for low-level configuration and recovery tasks, not for assigning fundamental system identifiers like the serial number.

Correct answer: Install and configure the Hitachi Remote Ops Monitor Agent and ensure it has secure outbound internet access.

The Hitachi Remote Ops Monitor Agent is the specific component responsible for 'call-home' functionality, proactive monitoring, and automatic support case creation with Hitachi Vantara. The installer must ensure this agent is configured correctly and can communicate securely with Hitachi's support infrastructure. SNMP and Syslog are for customer-facing monitoring, and creating local user accounts does not enable remote support.

Correct answer: Create one host group containing the WWPNs from all HBAs of all servers in the cluster and set the host mode to 'VMware Extension'.

For a VMware ESXi cluster, the best practice is to create a single host group that includes all the World Wide Port Names (WWPNs) from all Host Bus Adapters (HBAs) in the cluster. This allows any LUN presented to that host group to be visible to all hosts simultaneously. Additionally, setting the host mode to 'VMware Extension' or a similar VMware-specific option enables advanced VAAI (vStorage APIs for Array Integration) primitives, which offloads storage tasks to the array and improves performance.
