I've had the AppSpeed demo setup and running in one of my clusters. When you get the demo temporary license, its for 16 cores worth. My smallest environment to test in is 160 cores deep.
I figured no issue, I'll just see what I get for a couple different apps to see how it works. That didn't work out so well either. Any actually interesting app is multi-tier which happens to bounce across multiple cores/hosts in the environment.
So I haven't forgotten and I'm not ignoring the statement. I've put in a request for a temporary license of 160 cores worth and I'm waiting for that to come through. 3 weeks and waiting now.

In one of the environments I work in, we use Emulex drivers on all Windows systems. Along with that we use HP hardware. HP provides this nice Proliant Support Pack (PSP) that makes things really nice and bundled together. Along with that one can configure the PSP release around some parameters such as "Don't Install the Qlogic drivers" or "Configure these mgmt agents with this as their master management server to send traps to" and so forth.
In the past we would configure the HP enhanced drivers "Do Not Install". As these drivers don't work real well with non-HP Emulex devices.
Today I found out that you can not configure the Emulex Drivers in the PSP 8.25A release. If you are using the Emulex supplied HBAs and are running the HP PSP pack, don't use 8.25A.

Once again I'm reminded that going in and doing /etc/init.d/mgmt-vmware restart and then /etc/init.d/vmware-vpxa restart is fairly dangerous and should only be done as a LAST resort.
A co-worker was removing old NFS mounts and replacing them with new ones. So same named NFS mount was being used. He did an esxcfg-nas -d and then an esxcfg-nas -a and per our instructions, restart the mgmt agents so VirtualCenter would see them properly. In doing this with U4 plus a month of patches, VirtualCenter lost connectivity with the host agent with a vim.fault.NotAuthenticated.
The fix is to disconnect and reconnect as you can't put these systems into Maintenance Mode since VMotion doesn't work. Together we figured out a nicer way to do the mount point cleanup.
- esxcfg-nas -d
- esxcfg-nas -a ...
- vimsh -n -e "internalsvc/refresh_datastores"
- vimsh -n -e "hostsvc/datastore/refresh "

For the first time in a while I've found a "gotcha" between the CLI & the VMware Infrastructure Client.
When we did the updates the the latest ESX patches as of middle of June 09, the version # from running vmware -v and checking in the VIC client.
CLI version: 3.5.0 build-169697
VIC Client Version: 3.5.0, 163429
A friendly warning that build numbers don't match to any scheduled release anymore.

VMware vCenter AppSpeed product has just been officially released. For some reason I'm actually really hyped about this product. Guess its time to see if all the marketing foo really pays off and shows me a couple problem children and reasons in my environment. I'll start testing this soon and post my results.
