vmware srm - replicating over a wan - optimizations

Tue, 17 Aug 2010 00:00:00 +1200

I’ve been working through a SRM setup and have been looking at ways to optimize the amount of traffic that is sent over the WAN. The first obvious move is to move your vmware swap files off the replicated LUNS.

Another way is to reduce the sync window. i.e. how often is yoru replication technology trying to keep the source and destination in sync? – Increasing this window can sometimes help you out. But that all depends on your delta’s.

This is just a quick reference to create a multiplathing iSCSI setup…

Create two virtual kernel switches, one called “iSCSI-1” and the other called “iSCSI-2” (and so on if you have more nics)

Then per kernel portgroup ensure that only one of the nics is active. For the “iSCSI-1” portgroup configure it to override the virtual switch settings and move nic 0 to active and nic 1 to unused. For the “iSCSI-2” portgroup configure it to override the virtual switch settings and move nic 1 to active and nic 0 to unused.
