A customer has provided the pSeries technical specialist with details of an HACMP solution that they would like validated.  The solution is for two POWER4+ p630 servers directly attached to a FAStT600 storage server as the shared storage.  Each system has the following：
？ 2 integrated network ports ？  
2 fibre channel adapter cards  
？ 1 power supply and redundant cooling  
？ HACMP v5.1  
In addition to a second power supply， what further requirements， if any， are needed to validate this solution and ensure no single point of failure？ （）

A.Use eConfig to configure and validate each pSeries and p5 system.
B.Engage Advanced Technical Support to review any outstanding technical issues.
C.Confirm with the customer that the solution design meets their requirements.
D.Perform a Pre-Install Solution Assurance Review to validate required power requirements.

A.Direct the customer to the Installation Guide for each system to identify the power requirements.
B.Direct the customer to engage their site personnel to ensure the proper power connectors are provided to support the systems.
C.Direct the customer to the Site and Hardware Planning Information and review the system requirements for each new pSeries system.
D.Direct the customer to the Site and Hardware Planning Information to confirm that enough space is available in the rack to allow for proper airflow.

A、Order a new HMC to support the p5 system.
B、Attach the new p5 system to the existing HMC.
C、Upgrade the existing HMC to accommodate both the POWER4 and p5 systems.
D、Do nothing.  This system does not require an HMC.
