VNMC Hierarchical Policy
In cases in which multiple tiers of policy enforcement are required, the ASA 1000V may be combined 
with the VSG, the latter serving to provide additional security zoning within the tenancy container – i.e., 
below the “inside” interface of the ASA 1000V. This is illustrated in 
.
Unlike the physical ASA appliance, the ASA 1000V supports only active/standby failover. To maximize 
availability, active and standby systems should be placed on separate server blades. Heartbeats are 
exchanged between the failover pair over a failover link. When a failure is detected, the newly active 
ASA 1000V accepts all traffic destined for the ASA 1000V. Because of the failover link, the active ASA 
1000V already has connection state information for connections that were active before failover. 
Because only one context exists, preemption is not supported.
Cisco vWAAS
vWAAS is a key component of Cisco’s AVC (Application, Visibility and Control) product portfolio. 
Available in numerous form factors sized to fit a wide range of customer deployment requirements, from 
branch to HQ to data center, vWAAS provides end-to-end application performance optimization to 
improve response times and minimize the negative impacts of latency and limited bandwidth.
vWAAS 5.2 features enhanced integration with the Nexus 1000V, supporting vPath co-residency with 
virtual service appliances such as the VSG. In the VMDC VSA 1.0 architecture, release 5.2 version of 
the vWAAS-750 is used in tenant virtual private clouds with a router-integrated form-factor, the Cisco 
Services-Ready Engine module, on ISR G2s at remote customer premises. Resource requirements for 
vWAAS-750 are: 2 vCPU, 4 GB RAM, and 250 GB HD. In the data center Virtual Management 
Infrastructure (VMI), vWAAS Central Manager (vCM) provides domain management support for 100 to 
2000 devices. Out of band (OOB) management over the WAN to the vCM enables management of 
remote WAAS devices.
