HQT-4420 Hitachi Vantara Qualified Professional - Content Platform Installation Questions and Answers

The minimum RAM capacity installed in an HCP G10 server is 64 GB. This amount of memory is required to handle the workload associated with managing large datasets, metadata operations, indexing, data deduplication, and compression processes, all of which are essential functions of the HCP platform. The "HCP Hardware Specification Guide" outlines the minimum hardware requirements necessary to ensure optimal performance and scalability of the platform.

The HCP Data Protection Level setting identifies the number of copies of an object that the system maintains. This setting allows administrators to specify how many redundant copies of each object are stored across the system's nodes or storage devices, ensuring data durability and protection against hardware failures. The number of copies can be adjusted to meet the desired level of data protection according to the organization’s policy. This is explained in detail in the "HCP System Management and Configuration Guide."

The most cost-effective solution for a customer requiring 2 PB of usable capacity isHCP 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.

To configure an HCP S31 to its maximum capacity, the combination of1 x 4U100 and 8 x 4U106 traysis used. The 4U100 is a 4U enclosure that can hold 100 drives, while the 4U106 is another 4U enclosure that holds 106 drives. This combination allows for the highest possible storage density and capacity, leveraging the different tray sizes to maximize the total available storage.

The configuration maximizes the storage capacity supported by the HCP S31 system, as specified in the installation and hardware configuration guidelines.

For a running HCP (Hitachi Content Platform) system to maintain quorum for cluster operations, a majority of nodes must be operational. Specifically, this means that at least50% of the nodes + 1 nodemust be available to achieve quorum. Quorum is necessary to maintain consistency, availability, and coordination among the nodes in the cluster, ensuring that the cluster can continue operating correctly in case of node failures. This configuration avoids split-brain scenarios where multiple parts of the cluster operate independently.

The quorum requirement is designed to ensure that a majority of nodes are always participating in cluster operations, providing a safeguard against data corruption and ensuring high availability.

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.

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."
