What is NAS?
• High performance
for data access.
• Ease of installation
and management.
• Base on Ethernet
Infrastructure.
www.inventecesc.com
What is SAN?
• Customized network
device.
• Integrated storage
device.
• Base on Fiber
infrastructure.
• Isolated storage
device.

Major Differences
(NAS vs. SAN)
• NAS
Provide great spaces for application server to
be integrated.
(Like NFS, Mail, Web, FTP…etc)
• SAN
Separate servers and storage devices into
different units for management.
(Like Database, VoD, Backup…etc)

Today – Total Solution
SAN
NAS
Integrated Storage Device
– Combines the best of
both technologies
– Enhances NAS with
SAN scalability and
management
– Provides access to
storage network
backup, disaster
recovery and storage
management
– Reduces overall
management
complexity

Future  iSCSI
• internet SCSI
• IETF Standard
Please refer to
RFC3347…
• Enhances with
SAN’s original
