I was recently involved with planing an ESX server deployment for a client. The client had no windoze in house and was not willing to do so. So the 18 ESX servers were scraped for another VM solution.

This is the third ESX server implementation that I have seen flushed because VMware seems to be a windoze centric solution.

Good study case published at http://searchnetworking.techtarget.com.au/articles/35270-Case-study-Forget-1-GE-on-VMware-unless-you-can-do-without-vMotion-high-availability-and-fault-tolerance

"An attempted direct connection of NIC to VM eventually delivered close to 10GE performance, but with the unfortunate side effect of being possible only under VMDirectPath, a product that is not currently compatible with vMotion or VMware tools that offer high availability and fault tolerance."

Checklist for would-be users of 10GE under VMware:
* Check which PCI slot your NIc uses and make sure it can deliver the speed you need
* Turn on VT-X, NUMA, SMT and VTD in your server BIOS
* Use the vmxnet3 driver (or its successors) and not the e1000 driver"

NOTE - If VMware recommends vmxnet3 driver for 10GE Fault Tolerance will not work.

In adittion to PVSCSI devices VMware FT cannot be enabled on a virtual machine using VMXNET3

Sort of? Nope. That's still vSphere on Windows.

*Ensure that the virtual machines are NOT using more than 1 vCPU. (SMP is not supported.)

not good point .. it's hard to implement this FT for critical Machine (VM) .. especially at our environment min vCPU for our critical machine are 2 ..

This isn't a client, but it's the closest thing I found. Kinda sad really, I was hoping to stop using a second box to administer my servers. A true client would be nice.

A Linux, BSD, MacOSX client for esx/esxi has been "is coming", "coming soon" or the like for over 3 years. Meanwhile, some of us have gone to KVM, VirtualBox, etc. It's exceptionally sad really, that VMware couldn't pump out a Linux client BEFORE a windows client. Apparently, it works on vista/7. Just f#cking sad.
