3. What philosopher can tell
Storage is the NETWORK
transferring data along
time dimension.
-- Professor Xie, NUDT

4. So many terminologies around
Server SAN
Distributed
storage Software defined

NFS/CIFS
SCSI
NAS:
Data sharing
SAN:
Resource Sharing

7. Clustered file system
RAID
CFS
App
SCSI
CFS provide data
sharing capability
in SAN
Typical products:
Symantec VCFS
Oracle OCFS2
VMware VMFS
……

SCSI

8. Virtual storage
RAID
Virtual storage is
just additional
block level
aggregation on
top of SAN
Typical products:
IBM SVC
EMC VPLEX

9. Switched disk array
RAIDCTL
Disk array with
internal-linked
multi controllers
Typical products:
EMC VMAX
HDS VSP
IBM XIV

10. Distributed file system / clustered NAS
LocalFS
The earliest approach
to distributed storage
Typical products:
GlusterFS
EMC ISILON
IBM GPFS/SONAS
Lustre/OpenSFS
pNFS
PVFS/OrangeFS

11. Server SAN (distributed block storage)
App
Server SAN provides
resource sharing like
SAN, but no physical
SAN devices needed
Typical products:
EMC ScaleIO
VMware vSAN
HP VSA
IBM Spectrum-
Accelerate
AppApp

12. Web scale distributed storage
Typical products:
Ceph
HDFS
GoogleFS
MooseFS
MogileFS
