Re: [ceph-users] OSPF to the host

Hi, regarding clustered VyOS on KVM: In theory this sounds like a safe plan, but will come with a great performance penalty because of all the context-switches. And even with PCI-passthrough you will also feel increased latency. Docker/LXC/LXD on the other hand does not share the

Re: [ceph-users] OSPF to the host

Hi, Regarding single points of failure on the daemon on the host I was thinking about doing a cluster setup with i.e. VyOS on kvm-machines on the host, and they handle all the ospf stuff as well. I have not done any performance benchmarks but it should be possible to do at least. Maybe even

Re: [ceph-users] OSPF to the host

We do the same thing. OSPF between ToR switches, BGP to all of the hosts with each one advertising its own /32 (each has 2 NICs). On Mon, Jun 6, 2016 at 6:29 AM, Luis Periquito wrote: > Nick, > > TL;DR: works brilliantly :) > > Where I work we have all of the ceph nodes

Re: [ceph-users] OSPF to the host

Nick, TL;DR: works brilliantly :) Where I work we have all of the ceph nodes (and a lot of other stuff) using OSPF and BGP server attachment. With that we're able to implement solutions like Anycast addresses, removing the need to add load balancers, for the radosgw solution. The biggest issues

[ceph-users] OSPF to the host

Hi All, Has anybody had any experience with running the network routed down all the way to the host? I know the standard way most people configured their OSD nodes is to bond the two nics which will then talk via a VRRP gateway and then probably from then on the networking is all Layer3.
