if prevent vm's from being powered on selected
- HA restarts vm's on hosts with most capacity
- HA enforces failover capacity defined by cluster
Definition
Term
move virtual disks to another datastore by:
- migrating suspended machine

Definition
Term
functions of zoning:

Definition
Term
load balancing policies:
- explicit failover

- Originating Port ID

NOT SOURCE IP!!!! - it is Destination IP.
Definition
Term
to migrate from standard to distributed switch:
- edit virtual adapter settings for ESXi host and select dvPort Group

Definition
Term
Vmware iSCSI uses
CHAP
***NOT***
MSCHAPv2
Definition
Term

(Host specific things)
Definition
Term
To support jumbo frames, must modify
- vmkernel port
- virtual switch
Definition
Term
default size for / is 5GB
Definition
Term
use ESXi vs Server 2 because:
- can patch servers with zero downtime
- gives centralized management option
Definition
Term
remote console performance degraded - problem could be:
