This chapter describes how to configure storage resources in a storage system and allocate the resources to application servers for read and write operations.
Creating a Block Storage Pool
This section describes how to create a block storage pool from which application servers can use block storage space.
Creating Hosts
This section describes how to create a virtual host to establish a connection between a storage system and an application server, and add an initiator to the host to establish a mapping relationship between the host and application server.
Creating an Initiator
This operation enables you to create an initiator for a storage device.
Creating CHAP Authentication
To ensure the security of storage devices, you can configure CHAP authentication to restrict application servers' access permissions on storage devices.
Creating a Host Group
To allow hosts to use volumes, you must add hosts to host groups. Then, establish mappings between volume groups and host groups. By doing so, hosts in host groups can use volumes in volume groups. A host group can contain one or more hosts.
Creating a VBS
This operation enables you to create a VBS for new nodes and existing nodes.
Creating a Volume
The storage space of a newly created storage pool cannot be identified by a host. The host can use the storage space only after the storage space of the storage pool is divided into volumes and the volumes are mapped to the host.
Creating a QoS Policy
A QoS policy is a group of I/O performance targets. This operation enables you to dynamically allocate storage resources to meet a specified performance objective of a certain application.
Managing Storage Pools
A storage pool consolidates the storage space of different nodes for centralized management.
Managing Hosts
This section describes how to manage hosts so that storage resources can be allocated to the hosts and the storage system can connect to application servers.
Managing Initiators
This section describes how to add an initiator for the host to establish a mapping relationship between the virtual host and physical application server.
Managing CHAP Authentication
This section describes how to add CHAP authentication for an initiator when the initiator is being created.
Managing VBSs
This section describes how to manage the metadata of volumes through Virtual Block Systems (VBSs).
Managing Volumes
Volumes are logical disks accessible to application servers. They are allocated by controllers to enable the application servers to make full use of storage resources.
Managing a QoS Policy
This operation enables you to adjust the data flow performance to properly allocate storage resources.
Managing the iSCSI Service
On a public network, any application server whose IP address resides on the same network segment as that of a storage device's iSCSI host port can access the storage device and perform read and write operations on the device. This section describes how to manage the iSCSI service.
