[c-nsp] SLB Question

[Paul Stewart]

Thanks Arie... a quick look at the pricing makes this option prohibitive ...
nice option though...;)  If this was for a large scale rollout then the ACE
would be ideal....

This is pretty much just for two servers which are mirrored/redundant to one
another - looks like doing it on the server level is going to be best option
or go with something like Barracuda's load balancer appliance (can get a
pair of them redundant for under $10k) but we like to standardize on Cisco
as much as possible...

Thanks Arie and everyone for your input as usual....

Paul

Paul,

I recommend that you look at the ACE module. It's the latest and greatest HW
based SLB solution (a blade on the 6500):
http://www.cisco.com/en/US/products/ps6906/index.html

If you really need to be able to provide access to the VIP from the same
L2 domain where the real servers are located, I would recommend moving to
dispatched mode.
Just disable "nat server", and configure the VIP as a loopback interface on
the real servers (easily done on any OS). This would allow the servers to
use the VIP as a source, so both remote and local clients would be able to
access the VIP on the SLB instance, but the return traffic would not require
a translation back...

Cisco still makes some of the CSS line, but not sure that fits the bill.

  I'd actually take a look at the Foundry ServerIrons.  If you want a good
laugh, the Foundry ServerIrons are  more IOS like than Cisco's own CSS's.
;-)  The ServerIrons are solid and are quite reasonably priced...

vs what's left in the CSS line.  (I believe the CSS 11501's are EoSale).
