Hi,
I have 2 data centers with NetApp storage in each site. I am working in Asnc mode. between the sites I have an STM-1 Line with no latency (1-2ms).
when I replicate in a SnapMirror protocol i see that I get low BW utilization on my wan and a lot of TCP retransmissions.
I would like to optimize this situation with the WAAS RA mode.
few Q:
1.does the WAAS will optimize the traffic even if i have no latency ?, i know that the WAAS kicks-in in 4ms delay.
2. if it does, do i need to configure something special on the waas to work with the current delay i have ?
3. can i get the benefit of the DRE mechanism?, i understand that SnapMirror is replicating only the Changes.
Thanks,
