what is meant by Synchronization rate in SRDF

Hi friends,

what is meant by Synchronization rate in the following output.Is it related to bandwidth of our SRDF link.

Re: what is meant by Synchronization rate in SRDF

Synchronization rate is a measure of the amount of time it would take for your data to reach from your primary Symm to your secondary Symm, it depends on the following factors:

1. Bandwidth of the SRDF Links

2. Mode of SRDF operation used

HTH

Hi Sreehari,

In my output synchronization rate it is showing 0 MB/S.How can it be 0 with very little amount of data pending to write.

And we have dedicated link of 100mbps for replication purpose.

Re: what is meant by Synchronization rate in SRDF

That is the actual send rate when the command is run; if you have almost no data to send then it will be very low, possibly to low to register.

If you run the command a few times or use the interval/count option to automatically run the command over time you will get better numbers in that field.

For instance

symdg -g name query -i 10 -c 5

query the symdg every 10 seconds for a count of 5 times
