Use Cases for NetScaler SDX Appliances
Jun 03, 2014
For networking components (such as firewalls and Application Delivery Controllers), support for multi-tenancy has
historically involved the ability to carve a single device into multiple logical partitions. This approach allows different sets of
policies to be implemented for each tenant without the need for numerous, separate devices. Traditionally, however it is
severely limited in terms of the degree of isolation that is achieved.
By design, the NetScaler SDX appliance is not subject to the same limitations. In the SDX architecture, each instance runs
as a separate virtual machine (VM) with its own dedicated NetScaler kernel, CPU resources, memory resources, address
space, and bandwidth allocation. Network I/O on the SDX appliance not only maintains aggregate system performance but
also enables complete segregation of each tenant's data-plane and management-plane traffic. The management plane
includes the 0/x interfaces. The data plane includes the 1/x and 10/x interfaces. A data plane can also be used as a
management plane.
The primary use cases for an SDX appliance are related to consolidation, reducing the number of networks required while
maintaining management isolation. Following are the basic consolidation scenarios:
Consolidation when the Management Service and the NetScaler instances are in the same network
Consolidation when the Management Service and the NetScaler instances are in different networks but all the instances
are in the same network
Consolidation across security zones
Consolidation with dedicated interfaces for each instance
Consolidation with sharing of a physical port by more than one instance
