CloudSystem Console provides the capability to manage and track the use of block storage drivers,
volumes and volume types.
Managing Storage
Block storage drivers deliver the technology or vendor-specific implementations for the OpenStack
Block Storage (Cinder) functionality. CloudSystem Foundation supports direct attached storage for
3PAR Fibre Channel and iSCSI drivers. These drivers are connected to the management console
of supported HP 3PAR storage systems.
Volume types are associated with block storage drivers. When creating volume types, the type of
driver along with other specified storage parameters help define the provisioning characteristics
of the storage volumes. This provides a template that the cloud users can use to create volumes.
A block storage driver and a volume type must be defined before creating a volumes in the
CloudSystem Portal. The CloudSystem Console provides the ability to view the statuses of the
volumes and to delete volumes that are detached from VM instances.
Managing block storage drivers
Authorized infrastructure administrators use the CloudSystem Console to manage block storage
drivers. Adding these drivers is the first step in configuring your storage solution. Before you can
add a volume type or a volume, you first must have a driver to associate with the volume type.
You can add multiple driver types (Fibre Channel or iSCSI) to a storage system. When adding one
FC driver type and one iSCSI driver type to the same storage system, both must reside in the same
domain. Also, when adding an iSCSI driver you must have connectivity from the targeted compute
node to the 3PAR storage system iSCSI port. If you do not configure the connection, block storage
volumes will not attach to virtual machine instances.
After you have added the block storage drivers, you can use the CloudSystem Console to edit them
or delete them from the storage system. You only can delete block storage drivers that are not
associated with a volume type. If a block storage driver is associated with a volume type, you must
first delete the volume type before you can delete the driver.
Understanding block storage drivers data
The driver name and type (Fibre Channel or iSCSI) are shown in the General section.
The number of volume types and volumes to which each driver is associated, and the storage area
network (SAN) data transfer standard (Fibre Channel or iSCSI) used by the volume type are
displayed in the Details section.
The capacity (in terabytes) of each driver is displayed in the Utilization section. The capacity is
displayed as the amount being used in relationship to the total available capacity. For example,
23.2 of 25 TB.
Block storage driver data is displayed on the Block Storage Driver overview screen. The displayed
data providess details for each of the drivers you added, including the driver name and type,
volume type and volume association, and the capacity of each driver.
