Which two statements are correct regarding hardware upgrades on an HCP G10 system? (Choose two.)
A . Mixed clusters consisting of both G10 servers and CR servers are not allowed
B . Node additions are performed using the Configuration menu of the HCP setup program
C . Upgrades can be performed online or offline
D . Data is automatically rebalanced after upgrade

View Answer

Answer: C, D

Explanation:

Upgrades can be performed online or offline (C):

Hitachi Vantara’s HCP G10 system supports both online and offline upgrades, allowing administrators flexibility in how they choose to perform hardware upgrades. This capability ensures that the system can be updated with minimal disruption to operations. In an online upgrade, the system continues to run with full service availability, while an offline upgrade typically requires bringing the system down. This flexibility is critical for ensuring high availability and maintaining service level agreements. Data is automatically rebalanced after upgrade (D):

After a hardware upgrade, such as adding new nodes, HCP automatically rebalances the data across the cluster. This data rebalancing process is necessary to ensure that data is evenly distributed across all nodes, maintaining efficient storage utilization and performance. Rebalancing occurs as a background task without impacting the normal operation of the platform. HCP’s intelligent data placement algorithms manage this process, ensuring optimized performance and data integrity. These two statements accurately reflect how hardware upgrades and data management are handled in the HCP G10 system, as per Hitachi Vantara’s architecture.
