Can SIOC and Powerpath be used at the same time?

[ngerasim]

I have looked everywhere and ther eis no clear answer. Can SIOC and PowerPath be used at the same time on ESXi 4.1 Hosts?

Also, is there a new EMC PowerPath release supported for ESXi 5.0?

SIOC and Powerpath can be used both together, no problem.

Powerpath is just a Mulitpathing-Plugin that controls the usage of the available SAN paths for a LUN.

Storage IO Control is a mechanism to fairly distribute IO shares among VMs by controlling their queues' depth.

There is no interference between both.

According to the release date of an ESXi 5 compatible Powerpath version, I don't know, but I do not expect a great delay here.

I can confirm without a doubt they work together. I'm running PowerPath VE to both VMAX and DMX-4 and have SIOC running on both.

For PP for vSphere 5.0 just follow powerlink.

And be sure to check EMC AND VMware HCL.

I have been unable to find anythnig documented showing if PP is supported on ESXi 5.0

Powerpath will support ESXi 5.0 on day of release.

[ngerasim]

YAY!

Note, while we will have day 1 support, you will also likely need to install a PP update that day.

Thats understandable and expected. We have most of our DEV environment using 5.0 currently and are using MRU and RR. This is leading to performance limitations. I have adjust the queue dpeths of the HBAs and we are using SIOC to balance the loads, but PP makes a huge difference in overall performance.
