[SOLVED] Ceph Networking Optimization on Gig

Building a small home lab HA Proxmox/Ceph cluster with 3 Dell 210ii boxes. I'm trying to do it on the cheap and have decided to forego a 10Gb ring in favor of LACP'd 1Gb based network with quad port intel cards in each of the three boxes and an HP 1810G-24 switch. Due to ignorance I was originally thinking I could bond all four ports and have 4Gb of network capacity, but now that I'm doing the proper research to setup the cluster correctly I'm seeing that the LACP algorithm is going to force all connections from a specific MAC/IP through the same port. That effectively limits my total available bandwidth to 2Gb per box on the ODS network.

In an effort to sidestep this limit I'm wondering if Ceph can be configured to utilize an individual network interface (or bond) on a per OSD basis.
