Cisco Content Switch 11503

[snail945]

Directed towards any users of this product line out there.

I have a client who is on the older hardware platform (11100);. and is

looking to invest in a pair of new switches/balancers. I have the follwoing

outsntanding questions that i'm needing to confirm on the 11503

- Source NAT - is this required to always be on? for marketing, reporting and debugging purposes, we're wanting to ensure we can have the client's original ip address preserved once request hits web/app, not rewritten at the content switch.

- sessions - any concerns running up to 30 - 50k of simultaeous sessions on

the 11503? require the the addt'l session accel modeule?

thanks for the input.

An additional session accelerator module should be added if there are 30 - 50k sessions on the 11503.

Kindly refer the white paper in the following URl,

Byron,

source nat is not a requirement of the CSS.

It depends how you design your network and where you place the CSS.

If you do not want source nat, make sure the servers are placed behind the CSS and that the path from server to client always goes through the CSS.

For the amount of connections, each module can handle up to 200k concurrent connections.

So, the CSS with only 1 module should be ok.

Gilles.
