Categories of storage:
Block Storage:
Hard disk
Lvm
DAS (Direct Attach Storage)
is a direct connection to the host server, a storage method, each host server has a separate storage device, each host server storage device can not be interoperable.
In a single network environment, the data exchange volume is not high, the performance requirements are low, can be said to be an application of earlier technology implementation
SAN
1, Fc-san
2, Ip-san
Distributed Storage-ceph
Ceph is a PB-level Distributed file system implemented by open source, and its distributed object storage mechanism provides a file interface, block storage interface, and object storage interface for the upper layer.
DAS (Direct Attach Storage)

Cinder components:

Chnder-api. Accept the API request and route the request to Cinder-volume to execute.
Cinder-volume. The corresponding request, read or write to the block storage database, is maintained state, interacts with other processes through the information queuing mechanism (such as cinder-scheduler), or interacts directly with the hardware or software provided by the upper block storage. By driving the structure, he can interact with a multitude of storage providers.
Cinder-scheduler. Daemon process. Type in Nova-scheduler, selecting the optimal block storage provisioning node for the instance of the storage volume.

There is no cinder when the virtual machine disk storage location;

To install the Cinder control node:
[[email protected] ~]# yum -y install openstack-cinder python-cinderclient

See if the cinder database has been created and I have created it here at Keystone installation time;
