ACE One Arm Mode vs Routed Mode

Gents,

When is it required to use the One Arm Mode and one do I use the routed mode? Actually I am confused and would really like to know the pros and cons of each?

ACE One Arm Mode vs Routed Mode

Hi Hesham,

When you do not want to change the physical topology of your network then you usually go with ONE ARM mode.

Such as default gateway on server, IP addressing on servers. In this case client can access the server directly as well.

Its a flat network topology where your VIP and servers are in the same network ( VLAN ).

You use routed mode when you want to segregate the servers in seperate vlan and don't want to allow client to access it directly.

Client and VIP in same VLAN >>> ACE >>>>>> Server VLAN ( In this case we usually point the default gateway to ACE)

hope it helps.

regards,

Ajay Kumar
