Bridging SAN islands

VSAN implementations Brocade SilkWorm AP7420 LSAN technology is implemented on a standalone 16-port switch. It allows storage area networks (SANs) to share storage devices without merging the SAN fabrics. By deploying two AP7420s, the security and integrity of existing fabrics is maintained, the headaches of merging them is avoided and the benefits of gaining access to underutilized storage devices may be realized. Deploy this technology when looking to share resources while maintaining existing installations. Cisco MDS 9000 series VSAN technology supports up to 256 VSANs on a single director, and any port can be assigned to any created VSAN. The switch also supports moving ports between VSANS, so when ports are freed up, they can be moved nondisruptively between VSANs. Consider deploying the MDS 9000 in environments that are consolidating to one director where resources may need to be shared and one administrator will manage the switch. McData DS10000 Hard Partitioning technology is targeted at environments that are looking to ...

Features in this issue

  • Mobile Drives, Portable Backups

    Do mobile disk drives have a future in disk-based backup?

  • Bridging SAN islands

    To help ensure that a change made to one part of the SAN doesn't interfere with the entire storage network, some new products claim to have developed a new switch-based intelligence that segregates the SAN and protects SAN data.

  • WAN Links gain speed

    Can't get past the cost of doing high-speed remote replication? Latency problems driving you nuts? New TCIP/IP accelerators for IP storage promise some relief.
