Storage

The Ceph Dashboard offers a streamlined interface for configuring and managing NVMe-oF gateways and related services. Here's an overview of the key functionalities.

Managing NVMe-oF Services

The Ceph Dashboard enables the creation, configuration, and deletion of NVMe-oF services and their associated gateways:

1. Services:

• Set up NVMe-oF gateways and gateway groups.

• Enable mutual TLS (mTLS) for secure communication.

2. Best Practices:

• Ensure proper authentication and encryption for secure access.

• Configure resource limits based on workload requirements.

Accessing NVMe-oF Management

1. Navigation:

• Go to Block > NVMe/TCP in the Ceph Dashboard.

2. Tabs Overview:

• Subsystems Tab: Configure NVMe-oF subsystems, listeners, namespaces, and initiators.

• Gateways Tab: Manage gateway configurations and monitor statuses.

Subsystems Management

The Subsystems Tab allows comprehensive management of subsystems and their components:

1. Main Table:

• Displays basic subsystem information, such as:

• Subsystem NQN: Unique identifier for each subsystem.

• Number of Namespaces: Total namespaces configured.

• Max Allowed Namespaces: Capacity for additional namespaces.

2. Subsystem Details:

• Expand a specific subsystem to access tabs for:

• Details: View and edit subsystem configurations.

• Listeners: Manage listeners and their IP/port settings.

• Namespaces: Add, edit, or delete namespaces.

• Initiators: Add or remove initiator NQNs for subsystem masking.

3. Management Actions:

• View: Inspect subsystem configurations and performance.

• Create: Define new subsystems with specific parameters.

• Modify: Adjust existing subsystem settings, such as listeners or namespaces.

• Delete: Remove subsystems when no longer needed.

Gateways Management

The Gateways Tab provides a high-level overview of NVMe-oF gateways and their groups:

1. Information Displayed:

• Gateway ID: Unique identifier for the gateway.

• Hostname: Server name where the gateway runs.

• Status: Active or inactive state of the gateway.

2. Gateway Group Management:

• View gateway group details by selecting from the Selected Gateway Group list.

• Manage gateway configurations, including group-level settings.

Business Benefits

1. Simplified Operations: A centralized dashboard to manage NVMe-oF services reduces complexity.
2. Enhanced Scalability: Easy creation and management of subsystems and namespaces enable seamless scaling.
3. Improved Security: Features like mTLS and initiator masking enhance data protection.
