The HCP G10 nodes use eth2 and eth3 ports for back-end network connections. These ports are configured for communication between the nodes and storage or within the HCP cluster itself. Back-end networks typically handle internal data traffic, replication, and synchronization, and therefore use specific dedicated ports to ensure optimal performance and separation from front-end client traffic.

The back-end network is crucial for internal HCP operations, and using eth2 and eth3 aligns with standard configurations as defined in the installation guidelines for maintaining proper data flow and redundancy.

The default password for logging into the S10 or the S30 management console is 'Chang3Me!'. This default password is provided to ensure initial access to the management console, but it is strongly recommended to change this password immediately upon first login to maintain system security. Information regarding default credentials can be found in the 'Hitachi Vantara HCP S10 and S30 Management Console User Guide.'

When performing an online upgrade of an HCP G10 and the upgrade fails, the Arc-deploy logs are the relevant logs available to assist with troubleshooting. These logs contain detailed information about the deployment and upgrade processes, including errors or issues encountered during the upgrade. Accessing these logs allows administrators to diagnose the failure and take corrective actions.

The Arc-deploy logs are essential for understanding the sequence of events and identifying the exact step or component that caused the failure during an online upgrade of the HCP G10.

The HCP back-end network is specifically designed to handle internal cluster traffic such as inter-node communication. This traffic type is critical for maintaining cluster synchronization, managing metadata, balancing loads, and ensuring consistent data storage and retrieval across the nodes in the cluster. Other types of traffic, like BMC access (A), tenant management console access (B), and replication traffic (D), typically occur over separate management or front-end networks. The 'HCP Network Configuration and Management Guide' provides detailed information on network segmentation and the roles of different network types in an HCP environment.

The most cost-effective solution for a customer requiring 2 PB of usable capacity is HCP G10 with local storage and one S30 node (B). This configuration leverages the local storage of the G10 along with the large storage capacity provided by the S30 node, which is optimized for large-scale, cost-effective storage. The S30 node can store a significant amount of data, making it a suitable choice for achieving the required capacity with fewer nodes, reducing costs. The 'HCP G10 and S30 Configuration and Sizing Guide' provides more details on cost-effective configurations for various capacity requirements.
