Compare NAS with SAN. Introduction to Wolfman. What is Scyld from Penguin. NAS vs. SAN Presentation www.inventecesc.com
Traditional Mode DAS Direct Attached Storage www.inventecesc.com
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. www.inventecesc.com
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) Major Differences (NAS vs. SAN) www.inventecesc.com
SAN NAS Integrated Storage Device Today – Total Solution • 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 www.inventecesc.com
Future iSCSI • internet SCSI • IETF Standard Please refer to RFC3347… • Enhances with SAN’s original Infrastructure www.inventecesc.com
