Re: Bandwidth and latency requirements

[Karan Sandha <ksandha@xxxxxxxxxx>]

Hi Collin,

During our arbiter latency testing for completion of ops we found the below results:-  an arbiter node in another data centre and both the data bricks in the same data centre,

1) File-size 1 KB (10000 files ) 

2) mkdir   

	Latency	5ms	10ms	20ms	50ms	100ms	200ms
Ops	Create	755 secs	1410 secs	2717 secs	5874 secs	12908 sec	26113 sec
	Mkdir	922 secs	1725 secs	3325 secs	8127 secs	16160 sec	30079 sec

 

Thanks & Regards

Hi all

I've googled but can't find an answer to my question.

I have two data centers.  Currently, I have a replica (count of 2 plus arbiter) in one data center but is used by both.

I want to change this to be a distributed replica across the two data centers.

There is a 20Mbps pipe and approx 22 ms latency. Is this sufficient?  

I really don't want to do the geo-replication in its current form.

Thanks
