We used a different approach to this. Our CPU is a quad. We do not run VSE's turbo dispatcher in multi-engine mode as little of our workload is able to benefit. This limits each VSE guest to dispatch on a single CP and minimizes one VSE's ability to dominate the entire box. Note that each

2008-04-24 Thread Brian Nielsen
VSWITCHes are very nice for isolating the Linux guests from external VLAN requirements. The Linux guests can be VLAN unaware and the VSWITCH handles tagging and untagging all the frames. They are also very nice for failover to an alternate OSA. No need to burden the Linux guests with that.

Right, for redundancy, you'd want to have 2 different OSAs cards - each on a different physical switch. We have lost OSA cards here physical switches go down too (planned and unplanned). The vswitch will provide failover for all of the Linux servers. Dedicating OSA addresses and having failover
