VMware just uploaded a cool PDF about configuring an iSCSI SAN. This particular PDF is created by EMC and deals about an EMC Celerra iSCSI SAN but there’s more than enough useful info in there for those who don’t own an EMC iSCSI SAN.
The cool thing about the Celerra is the possibility to use “network load balancing”. Where most iSCSI SAN’s work with a group address, which forces ESX to always walk the same path, the Celerra SAN’s use multiple interfaces with multiple ip-adresses. Would like to see this in real life…
