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 detailedinformation on network segmentation and the roles of different network types in an HCP environment.

When installing an HCP G10 and setting up front-end connectivity, two critical actions must be performed on each node:

Set the BMC IP Address (A):The Baseboard Management Controller (BMC) IP address must be set to allow for remote management and monitoring of each node. This is crucial for out-of-band management, especially in large data center environments where physical access to servers may be limited. Configuring the BMC IP address is typically done during the initial setup of the operating system on the HCP node.

Set the Front-End IP Address (C):The front-end IP address, which is used for client network traffic, must be configured as provided by the customer. This IP address allows each node to communicate with the client network, and it is a key part of the configuration during OS installation.

These configurations are detailed in the "HCP G10 Network Configuration Guide" and the "HCP G10 Installation and Configuration Manual," which provide step-by-step procedures for setting up both the BMC and front-end IP addresses.

To convert the installation media ISO image to a bootable USB drive, the "Rawrite32" tool from the "HCP-G10-Tools" package should be used. Rawrite32 is specifically designed to write ISOimages to USB drives, creating a bootable medium for installing or upgrading the HCP system. This tool is commonly used for preparing installation media in Hitachi Vantara environments and is documented in the "HCP G10 Installation Preparation Guide."

If the pre-upgrade check procedure fails due to insufficient capacity on node 103 to perform the upgrade, the service procedure to run isFree Space On Nodes. This procedure helps to identify and clear unnecessary files or redistribute data, freeing up the required capacity on the node to proceed with the upgrade.

The "Free Space On Nodes" procedure is specifically designed to manage and optimize storage capacity across HCP nodes, ensuring that upgrades and other operations have adequate space to execute successfully.

To configure host group security on a new HCP G10 with attached storage, the World Wide Port Name (WWPN) is required. The WWPN is a unique identifier for each Fibre Channel port in a storage area network (SAN) environment. It is used to configure access control and define which hosts can communicate with specific storage resources. This setting ensures that only authorized hosts can access the storage, enhancing the overall security of the HCP system. This requirement is documented in the "Hitachi Vantara HCP G10 Storage Configuration Guide."

To upgrade a four-node HCP G10 cluster to an eight-node cluster, the customer can use additionalG10orG11node models. The HCP platform supports the addition of both G10 and G11 nodes in the same cluster, as they are compatible with each other in terms of architecture, management, and functionality. This allows the cluster to be scaled up by adding more nodes of either model to meet growing storage and performance needs.

When expanding an HCP G10 cluster, it is crucial to use node models that are supported and compatible with the existing cluster configuration, such as G10 and G11.

For the HCP G10 SSD option:

Two SSD disks are installed at the rear of the server (A):This is correct. The SSDs in the HCP G10 server are typically installed at the rear of the server to provide fast access to critical system data, such as metadata and indexes.

Software RAID1 is used to mirror the disks (C):This statement is also correct. Software RAID1 provides mirroring of the SSD disks, ensuring redundancy and data protection in case of a disk failure. RAID1 is chosen for its simplicity and reliability in providing redundancy without requiring additional hardware. Details can be found in the "HCP G10 Hardware Configuration and Maintenance Guide."
