AGENDA

Vitalizing the DC network for Virtualized servers

How do we design DC network with QFabric


NETWORK & RESOURCE POOLS IN DATA CENTER

USERS/TENANTS

Tenant-1

Tenant-2

Tenant-3

Tenant-450

Compute & data pools Virtualized workloads

Servers & compute capacity outpacing infrastructure growth Network needs to enable flexible resource pools and scale on the same time
