  • Thread-topic: Block Alignment - Any XCP guidance?

At work I am having lots of discussion on block alignment with NetApp.  As I read various forums there is lots of advice on checking/fixing block alignment however it appears to be very VMware focused.  I note Win 2008 R2 and Centos 6 automatically start partitions at 4k block boundaries but Centos 5 does not. 

 

So my key Q is – as XCP uses Centos 5 as Dom0 and is therefore not block aligned is there a performance hit in using local ext3 storage repositories (my reading suggest LVM SRs should not be impacted)?  If yes is there a way to avoid/correct this? 

 

Regards,

 

Jon
