Proxmox requirement : 2*10gb, why ?

[larsislars]

Hello,

2*10 gb/s it's for aggregation ? it is to have 20gb/s bandwidth ?

Or it's for backup (if a link is down another take over) ?

I don't understant that...

It's not a requirement, it's a recommendation written for enterprise in mind.

2*10Gb/s links is both for redundancy and bandwidth. You can get by just fine for small loads with a few bonded Gig cards, or even a single gig if you're feeling risky.

With the cost of 10gb dropping drastically though, it won't be long until we see it everywhere.

You only need 10 GBit if you're using iSCSI. If you have FC (or any other dedicated shared storage network), 1 GBit is sufficient if you do not want to migrate a lot of machines in parallel.
