SnapMirror updates timing

Dear Netapp Gurus,

 

is there any recommendation for the minimal time gap between SnapMirror updates? In my case, it needs to be transmitted 50GB of data per update and there is 1Gbps Ethernet link. Roughly said, 50GB is transmitted in cca 7 minutes. Is it correct assumption?

So roughly you'd get 100 MB/s (Gigabit), so in a perfect world 7-9 minutes is about right. But not all things are equal, so I'd suggest testing. Another option is Synchronous SnapMirror, but make sure your WAN is really small and super low latency.

Hi @paul_stejskal , thank you so much for your reply. Indeed, I have the same assumption as you, which tells me that my guess is the right one.
