Different CPU's in HA/DRS cluster

Hi,

we currently have two ESX servers in our HA/DRS cluster: HP ProLiant DL580 G4 with the following CPU info:

processor : 0

vendor_id : GenuineIntel

cpu family : 15

model : 4

model name : Intel(R) Xeon(TM) CPU 2.80GHz

stepping : 8

cpu MHz : 2793.134

cache size : 1024 KB

fdiv_bug : no

hlt_bug : no

f00f_bug : no

coma_bug : no

fpu : yes

fpu_exception : yes

cpuid level : 5

wp : yes

flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss tm nx lm

bogomips : 5570.56

Now we want to expand the cluster with a new server. If possible, we'd like to buy a DL380 G5 with quad core processor. Indeed, we're unsure, if this constellation will work without cpu masquerading!!! Sure, if the cpu flags are different, we have to do masquerading, but if possible we wanna avoid that (seems to be a complex topic!).

Does anyone of you have these informations?

Thanks and regards

Marco

It won't work without CPU masking.
