vmax fa processor
Is there a single (quad core ) prosessor for Fa 7E0 & 7E1 in V-Max same as old DMX family one processor for 7a0 & 7a1 or its different processor ??

Single procesoor for the 2 ports 7A0 and 7A1

VMAX uses Intel quad core CPUs. There are 2 chips per director (8 cores total per director, 16 per engine). A single core is assigned to each emulation or slice. So 7E0 and 7E1 in your example are assigned one of the eight cores.
In DMX, the CPUs were physically seperate from one another, and they were PowerPC CPUs. The FA slice in DMX3/4 used two of these CPUs, one for link tasks and one for emulation tasks.

Still having the confusion. You say 2 quad core processor . So let say 8 processor for Director 7 . Now i got 8 FA's for Dir 7 namely 7E0,7E1,7F0,7F1,7G0,7G1,7H0,7H1 . So will i have one processor per FA port ??? or One processor for pair 7E0&7E1 then i just need 4 processors what rest 4 processors's going to do
About DMX yes they are PowerPc. can you please elobarate your line--> "The FA slice in DMX3/4 used two of these CPUs, one for link tasks and one for emulation tasks. " Or send me sone DOC where i can find the details .

For VMAX:
For director board 7 there are 4 CPU cores assigned to DA slices, and 4 cores assigned to front end slices, for a total of 8 CPU cores on the director board. Port 0 and port 1 on a slice (7F for example) share one CPU.
For DMX3/4 there are two CPU cores assigned to each DA slice and each FA slice. One core handles the Engunity tasks (emulation or internal operations) and the other handles the link transfer and protocol. This is how the work is divided up between the two CPUs. Logically they look like one CPU. Port 0 and 1 also share the same CPU complex on DMX.

Thanks for Brief & Happy New Year.
So that means V-Max are more powerfull as they got 4 core dedicated for FA while in DMX its just 2 core .

You have part of it right. The FA slice (two ports) on VMAX can do about twice the IOPs (small block) as as compared to DMX3/4.
However the FA slice (two ports, 0 and 1) have half the CPUs. On DMX 3/4 a FA director board has 8 CPUs. On VMAX, the equivalent is 4 CPUs. A FA slice (two ports) on DMX has 2 CPUs, on VMAX, the FA slice (two ports) has 1 CPU.
Happy new year to you too!
