VMWare Virtual Infrastructure Management

Snapshots
- Must be temporary
- cannot vmotion a guest with snapshot(s)
- might take several hours to commit a 100G snapshot
Networking
- In order to enable iSCSI:
- iSCSI requires both a service console portgroup and a vmkernel portgroup. The SC portgroup handles communication with the "storage processor" or equivalent while the vmkmernel will handle the data transfer.
- sample commands to enable iSCSI:
esxcfg-vswitch --add vSwitch2 esxcfg-vswitch --add --link=vmnic2 vSwitch2 esxcfg-vswitch --add-pg=iSCSI vSwitch2 esxcfg-vmknic --add --ip 192.168.1.15 --netmask 255.255.255.0 iSCSI esxcfg-vswitch --add-pg="iSCSI Service Console" vSwitch2 esxcfg-vswif --add --ip 192.168.1.16 --netmask 255.255.255.0 --portgroup "iSCSI Service Console" vswif1 esxcfg-swiscsi --enable /etc/init.d/mgmt-vmware restart
VMware HA
- HA will fail and general environment performance will be reduced if there is not sufficient free space on each storage volume shared among ESX hosts. My general rule is to maintain at least 10 - 15% free space.
