vCenter Server is the centralized management utility for VMware,
and is used to manage virtual machines, multiple ESXi hosts, and
all dependent components from a single centralized location.
VMware vMotion and svMotion require the use of vCenter and ESXi hosts
vCenter Server – Application or Virtual Appliance
-Manages – vSphere/ESI hosts, High Availablity(Cluster)
Network, heart beats, VMs, Storage – SAN,NAS
FC Switch, ..VSAN,DRS
VMware vSphere® Distributed Resource Scheduler™ (DRS) is the
resource scheduling and load balancing solution for vSphere.
DRS works on a cluster of ESXi hosts and provides resource
management capabilities like load balancing and virtual machine (VM) placement
