Hi all,
I need advice for redundancy with CRS125. Didn’t use CRS much, but in this case it is mandatory to use CRS.
I have the following topology (there are more servers, but it is same prinicple for all):
With classical switch I’d turn on stp on all ports, but as I notice the CRS doesn’t have STP in switch mode only in bridge mode. I’ve read that maximum throughput in that case (CPU processing) is aprox 1GB for whole CRS. Is this true?
If i put all ports in bridge and turn on rstp I will be limited with 1GB throughput.
I’m not sure about server and NIC configuration (done by the client). Is there a way to configure two NICs for the failover without me needing to use STP?
What about aggregation protocol between CRSs, which one should I use? I’m confused with the wiki and comments I’ve read. It supports 802.3ad but only on bridge (CPU processing again). What is recommended aggregation protocol in switch mode?
