I would like to get in touch with any Storage experts to assist me with this peculiar issue.

I am getting serious replication lags on some servers (Exchange, SAP, SUN) when using asynchronous snapmirror replication.

I have a riverbed device at both sites but still no success.

Are they specific settings need to be done on Riverbird for netapp snapmirror traffic to assist improve data transfer across WAN.

    how much lag do you have?  Have you seeded both units prior to taking the DR Netapp offsite?

    You will need to figure out:

    1.  How much data is changing
    2.  What type of compression you're getting
    3.  Calculate whether your compressed data has enough bandwidth to support your RTO
