Karim,
Depends on KS hardware. For example, single c7200 is able to support up to
2000 GMs (for Phase 1.0) and more (in latter phases).
This depends on two factors:
1. registration speed (c7200 can handle ~12 registrations/sec for PKI and 30
reg/sec for PSK)
2. registration window (different for each GETVPN Phase, for 1.0 this is
30sec, for Phase 1.2 this is 150sec by default)
As Tyson said, you should contact your Cisco representative to scale it
right.
HTH,
