IP Storage
 iSCSI storage and NIC drivers provide NAS/FC
alternative
 Block I/O storage access over 10 G Ethernet to iSCSI storage
 Replaces NAS/FC for single network architecture
 New switches with high-end FPGA, optional FC ports

Future Is Bright for Storage Networking!

Backup/restore
 Backup to tape devices in remote locations
Today’s
Applications
 Eliminates manual handling and transportation to offsite
location
 Secure archiving and timely retrieval

Data replication
 Real time data mirror to multiple storage disks
 Connection of disks over geographically separate locations
 Reduces risk of disasters, improves business continuity
Future
