Planning to implement SRDF/A and our network group is giving 2x400mb/s redundant links.They were saying that the bandwidth utilization is up to storage devices means we can throttle 800 out of this.I have this basic question.If we connect these links to two adapter each 400mb,how does Symm distributed the load?Is it going to do load balancing? or is it going to use only one link?
I have no further details .. I've simply experienced this behaviour in the last few hour .. my customer removed 4 DWDM link, breaking half of our SRDF links .. SRDF handled the issue using only available links .. ..
Now the customer replaced the DWDM link and all RF adapters are spreading the workload between all paths
SRDF have a "PowerPath" inside, spreading the workload and balancing it on every available link .. and resuming paths when links comes back
Absolutely ! I've seen 2 RA's of 2Gb each pushing data over 1.2Gbps (1 x 800Mb and 1 x 400Mb using Cisco 9216i's and FCIP) at 400 MegaBytes per second ("some" compression was involved), so if you have a true SAN between the 2 Arrays (not FCIP or something) you theoretically should be able to do 2 x 2Gb on 2Gb ports and 2 x 4Gb on the latests models, so 800MBps. Only 80 is "nothing"....
