- Introduction to Hitachi Content Platform
- No image available
- Hitachi Content Platform (HCP) is a distributed data storage system designed to support large, growing repositories of fixed-content data. An HCP system comprises hardware (physical or virtual) and software.
- HCP administration
- No image available
- As an HCP system-level administrator, you play a role in ensuring the continued viability and accessibility of the HCP system. The primary tool for these purposes is a web application called the System Management Console.
- Account administration
- No image available
- As an HCP security administrator, you are responsible for creating and managing HCP system-level user and group accounts. These accounts give users permission to access the HCP System Management Console, the Tenant Management Console for the default tenant, the HCP management API, the HCP metadata query API, and/or the HCP Search Console for the default tenant. For the System Management Console and Tenant Management Consoles and the management API, these accounts also determine which actions the user is allowed to perform through the applicable interface.
- System-level administration
- No image available
- To monitor the HCP system as a whole, you use the Overview page in the System Management Console. You use this page to view system activity, including service runs, repository usage, and search facility indexing progress. Additionally, this page notifies you of conditions that may require intervention, such as physical drive failures and low storage capacity.
- Hardware administration
- No image available
- The System Management Console offers both a summary view of all the nodes in the HCP system and a detailed view of each node on the Hardware and Storage Node pages, respectively. The Hardware page also provides a view of other hardware components used in the system. Using these pages, you can monitor both system hardware and system storage.
- Storage administration
- No image available
- By default, HCP stores all objects in a repository on primary running storage. However, you can use HCP S Series Nodes as an alternative to primary running storage. HCP also supports the use of primary spindown storage (SAIN systems only), HCP S Series storage (storage provided by S Series Nodes), and extended storage for tiering purposes.
- Network administration
- No image available
- An HCP system can be configured to support virtual networking. Virtual networking enables the segregation of network traffic between clients and different HCP tenants, between management and data access functions, and between system-level and tenant-level traffic. This segregation enhances the privacy and security of communications over the HCP front-end network.
- Tenant administration
- No image available
- Tenants are the administrative entities that own and manage namespaces. When an HCP system is first installed, no tenants exist. You use the HCP System Management Console to create them as needed.
- Search administration
- No image available
- HCP supports two search facilities: the metadata query engine and the Hitachi Data Discovery Suite (HDDS) search facility.
- HCP policies
- No image available
- An HCP policy is one or more settings that influence how transactions and services work on objects in namespaces. Policies ensure that objects behave in expected ways.
- HCP services
- No image available
- HCP services are responsible for optimizing the use of system resources and maintaining the integrity and availability of the stored data.
- System security
- No image available
- Through the HCP System Management Console, you can set various options that affect HCP system security.
- System monitoring
- No image available
- HCP maintains a system log in which it records messages about events that happen within the system. You can view this log in the HCP System Management Console. You also have the option of sending system log messages to syslog servers, SNMP managers, and/or email addresses. Additionally, you can use SNMP to view and, when allowed, change HCP system settings.
- Licensing
- No image available
- A license specifies the amount of storage and the HCP features that you can use. The storage can either be on HCP and S Series Nodes or on an extended storage tier. Licenses are available for all system configurations (RAIN, SAIN, and HCP Virtual Machine).
- Troubleshooting
- No image available
- From the system console for any HCP node, you can run selected diagnostics that can help with analyzing and resolving issues with interactions between the node and other components in the HCP environment.
- System Management Console Alerts
- No image available
- The HCP System Management Console uses icons with hover text, called alerts, to provide high-level health status reports for specific elements of the HCP system and to identify problems that need your attention.
- HCP system log messages
- No image available
- HCP maintains a log that records messages about system events. The following table lists each possible event, provides an explanation of the event and a recommended action plan, and categorizes the event severity. The events are listed in ascending order by ID.
- Zero-copy failover behavior
- No image available
- In a SAIN system, zero-copy failover is the process of one node automatically taking over management of storage previously managed by another node that has failed. Support for zero-copy failover is configured at the storage tier and enabled in the HCP system configuration.
- SNMP MIB support
- No image available
- You can use SNMP with HCP to view and modify system settings and receive notifications of certain types of events. HCP comes with a MIB, defined in the HCP-MIB.txt file, that includes fields and traps specific to the system. HCP also supports many of the standard Linux-based MIBs available with SNMP.
- Configuring DNS for HCP
- No image available
- Domain name system (DNS) is a network service that translates, or resolves, domain names (for example, example.com) into IP addresses for client access. The service is provided by one or more servers, called name servers, that share responsibility for resolving client requests.
- Configuring Active Directory to support HCP
- No image available
- An HCP system can be configured to support Active Directory. With the system configured this way, you can create HCP group accounts that correspond to AD groups at both the system and tenant levels. AD users in those AD groups then have access to HCP through the various HCP interfaces, subject to the roles and permissions associated with the HCP group accounts.
