PS4100xv with VMware ESXi 5.1
Hi,
I got a Dell PowerEdge server R420 connected to an EQL. Installed is ESXi 5.1 U1 (free version).
One VM runs Windows 2008 R2 STD with MS SQL 2008 R2 STD. The change in database size per day is around 5 to 10 MB base on my daily full backups.
However, when I initiate a replication session between my PROD EQL and DR EQL that delta size is ranging from 1 GB to 50 GB each time I executed a replication to occur? Interval is around 5 to 10 minutes. I tried 20 mins also the size to be replicated is erratic.
Hope someone can help me on this.
Thanks,
Paul

Replication is not like a backup. As SQL writes to the physical disk, these writes can be spread across multiple storage blocks. Replication will replicate the changed blocks to the partner. Backups only copy files with the archive bit set, so it is possible that only a few files are touched, but the files are spread across many blocks.
You may want to open a case with support so they can review the array(s) diags to see if anything unusual is taking place.
