Hi all ,
Here is my understanding about the stroage in the openstack, I am very
happy about that who can figure out the wrong meaning or add your comment
for this.
Right now, there are two main kinds of storage needed by Openstack. One is
for Image, the other one is for Volume. These two support many kinds of
storage.
Image ( Glance servicer ):
File
NAS
CIFS
NFS
FTP
...
SAN
ISCSI
AoE
...
Local
HTTP
RBD(Ceph)
S3
Swift
Volume (Cinder/nova-volume)
SAN
ISCSI
AoE
....
Local
LVM
RBD (Ceph)
Sheepdog
Questions:
1. What's the position for swift. It is just the image container for the
glance server?
2. Is there any rules when making choice?
2. What's your tend to choice in so many solution? and why?
