Hi,
Our network administrator raise an interesting question as he want to consolidate multiple RAC private interconnect on to a (network) domain, i.e.,
Server A - NIC port A1
- NIC port A2
Server B - NIC port B1
- NIC port B2
Server C - NIC port C1
- NIC port C2
Server D - NIC port D1
- NIC port D2
He is wondering if we can bond/team both port and use VLAN tag (to split the public/private/ASM traffic)
Server A - > team0 (A1 + A2) -> VLAN0 (public) team
VLAN22 (private), team.22, 192.168.22.8.0/27
VLAN222(ASM), team.222
Server B - > team0 (B1 + B2) -> VLAN0 (public) team
VLAN22 (private), team.22, 192.168.22.8.0/27
VLAN222(ASM), team.222
Server C - > team0 (C1 + C2) -> VLAN0 (public) team
VLAN22 (private), team.22, 192.168.22.128.0/27
VLAN222(ASM), team222
Server D - > team0 (D1 + D2) -> VLAN0 (public), team
VLAN22 (private), team22, 192.168.22.128.0/27
VLAN222(ASM), team222
Now,
Server A and Server B make into RAC1
Server C and Server D make into RAC2
VLAN0 on RAC1 and RAC2 can be shared. no problem.
Can I share VLAN1 for both RAC1 and RAC2? (given the overlay (V)IP, 169.xxx/16) is assigned by clusterware) If it is do-able, should I be worry about and manually update the private overlay subnet mask? To prevent 2 independent cluster talking to each other?
