SAN Storage Management

Storage Area Network (SAN) provides block-level storage to servers with high-performance network architecture.

SAN Components

SAN Zoning (Brocade)

ssh admin@san-switch01


Create alias


alicreate "server01_hba1", "21:00:00:24:ff:11:22:33"
alicreate "storage_port1", "50:00:00:00:00:00:00:01"


Create zone


zonecreate "zone_server01", "server01_hba1;storage_port1"


Enable config


cfgcreate "production_config", "zone_server01"
cfgenable "production_config"
cfgsave

Linux Multipath

sudo dnf install device-mapper-multipath
sudo mpathconf --enable


/etc/multipath.conf


defaults {
    user_friendly_names yes
    find_multipaths yes
}


sudo systemctl restart multipathd
sudo multipath -ll

Conclusion

SAN storage is ideal for high-performance workloads. Multipath provides redundancy.
