Subject RE: Improving SSVM performance
Date Thu, 05 Dec 2013 17:02:10 GMT
Deploying templates - copying from Secondary to Primary Storage - is handled by the Host and
not the SSVM

Exporting Templates is handled by the SSVM using its 'Storage Interface' to read from Secondary
Storage, and its 'Public Interface' to export it to the logged in user.


Improving deployment times would be best achieved by enabling Jumbo Frames on the Secondary
Storage Device and the NIC/Bond/vSwitch on the Host dedicated to Secondary Storage and obviously
the networks connecting them (this assumes you are using the Storage Network within CloudStack
and hence have dedicated NICs)

There is also a SSVM MTU Global Setting which will also enable Jumbo Frames on the 'Storage
Interface' of the SSVM, but this will not change the MTU on the Public Interface which will
probably be your bottleneck


So for optimal Deployment, use the CloudStack Storage Network, have dedicated NICs on the
Hosts, and use Jumbo Frames.

For optimal Exporting, the Public Network will be your bottleneck, and as this is typically
going over the Internet, using Jumbo Frames is not really an option.

Hey Simon,

Got round to testing this in my lab. Times to complete Export OVF commands didn't improve
massively:

10Gb template with SSVM on E1000:               03:21.18 (10GB)

10Gb  template with SSVM on VMXNET3:          03:17.18 (10GB)

60Gb  template with SSVM on E1000:      18:32.16 (60GB)

60Gb  template with SSVM on VMXNET3: 18:12.98 (60GB)


Any other thoughts on how to speed stuff up? Where would the bottleneck lie; storage for NFS
mount?
