You are configuring a single engine VPLEX Metro to support both local and distributed volumes.
The VPLEX will utilize 10Gb WAN-COM modules in a routed configuration.
According to EMC best practices, what is the minimum number of subnets and IPs required?
A.
7 subnets; 15 IPs
B.
5 subnets; 15 IPs
C.
3 subnets; 7 IPs
D.
3 subnets; 30 IPs
Explanation:
All of sudden, nobody is posting any comments for this one??? Thought so – everyones just copy pasting answers. For those that don’t know how to work this out;
– Single engine Metro has 4 directors.
– Considering 4 WAN-COM ports being used on each director in the ideal scenario, you will have 4×4 = 16 WAN-COM ports utilized in total which means you will need 16 different IPs. This means the answer can be A or B.
– Now, considering the subnets – two of the WAN-COM ports can be in the same subnet. This means, you have 16/2 = 8 subnets. Answer is A!
You are welcome.

I think, that here is the question about the total subnets and IPs for cluster (there will also be a Witness server, mgmt ports, WAN COM etc. So the answer is not so simple as 4 ports on 4 directors = 16…

VS2 have only 2 ports for WAN-COM per director.
