vDS switch design - one vds with all port groups or many vds with same functionality port group

[myoth]

Hi All,

Assuming: I have 8 physical uplinks.4 Vlans and go to 4 different switches.

2x Management

2x vMotion

2x VM network

2x Backup

scenario 1: create 1vds switch with 4 port groups (all uplinks go to 1VDS)

scenario 2: create 4 vds switches and each port group under them. ( different uplinks go to different vds)

What is the best practice?

My thinking is creating 4vDS makes easier to identify uplinks and their usage. Apart from that, is there any pro can cons?

regards,

Max

design best practice says, try to have less number of virtual switches, preferably one.

but then requirements coming from customer would definitely be ultimate goal.

scenario 1: create 1vds switch with 4 port groups (all uplinks go to 1VDS)

I would go with this and do Virtual Switch Tagging (VST)

scenario 2: create 4 vds switches and each port group under them. ( different uplinks go to different vds)

if there's a specific need to achieve complete physical separation, and I am not allowed to do VST, then I will go with this scenario, here I still have leverage to do External Switch Tagging (EST).
