Hi!

At the moment, I am thinking about a new system using DRBD (Xenserver with VMs using databases).

To get higher throughput and lower latencies, I wanted to stop using 1 Gbit Ethernet as replication link and started to read posts about DRBD with alternative connections like:

- 10 Gbit/s Ethernet
- Infiniband (IPoIB)
- Dolphin

10 Gbit Ethernet would be the "easiest" an cheapest solution, but is it a good idea to use it?

What are your expiriences?

Best wishes,
Phil
