NetScaler Topologies Comparison

Source: Understanding Common Network Topolgies

Topology	Two-Arm (inline)		One-Arm
	Multiple Subnets	Transparent	Single Subnet	Multiple Subnets
Client/Server IP	on the different subnets	on the same subnet	on the same subnet	on the different subnets
VIP	public subnet	no VIP	on the NetScaler	on the NetScaler
SNIP	private subnet	n/a	n/a	private subnet
NSIP	private subnet	public subnet	public subnet	private subnet
MIP	n/a	public subnet	public subnet	n/a
Server IP	private subnet	public subnet, configure the default gateway as the MIP	public subnet	private subnet
Layer 2 Mode	n/a	must enable	n/a	n/a
Use SNIP Option	must enable	n/a	n/a	must enable
Others	the most commonly used topology	if the clients need to access the servers directly NetScaler is placed between the client and the server	connect one of the NICs to switch	connect one of the NICs to switch
