FT not working due to CPU compatibility and EVC mode

Hi guys,

 

1) can you explain me why FT doesn't work? even if I have running EVC mode. I thought, EVC ensure CPU compatibility for FT.

 

I have two servers with NFS and vSphere 55 in my lab. One server is

Intel Core i7-4770 Haswell 3.4GHz LGA 1150 84W

and second one is

Intel Xeon E3-1275 V2 Ivy Bridge 3.5GHz (3.9GHz Turbo) 8MB L3 Cache LGA 1155 77W

 

EVC is running in "Sandy Bridge" mode.

 

FT is enabled and first is on i7 and second is on E3, when I try start vm tu run this error is issued:

 

Cannot power on the Fault tolerance Secondary VM for virtual machine.

- 192.168.1.200 The CPU pair is not compatible for fault tolerance:

CPU model does not match

See KB 1008027.

- 192.168.1.201 Virtual machines in the same Fault Tolerance pair cannot be on the same host.

 

 

2) what do you thing if I change first CPU (i7) for Intel Intel Xeon E3-1230V3 Haswell 3.3GHz LGA 1150 80W Quad-Core Server Processor

 

should it work?

 

 

Thank you,

 

Tomas
