[ixpmanager] Advice me please

[Nick Hilliard (INEX)]

Hi Basil,

At INEX, we split services over different VMs to keep them as separate 
as possible.  This means we can perform maintenance on individual 
components relatively easily without affecting other components. 
Currently we have the following configured:

1. database VM
2. ixpmanager web front-end VM
3. monitoring VM (mrtg / nagios)
4. sflow VM
5. 2x rpki VMs
6. route collector VM
7. as112 server vm

We run route servers on different physical servers. They're kept 
separate (different hardware, different hypervisor, not attached to the 
orchestration system) because they're categorised as critical production 
servers, i.e. if they go down, production IXP traffic may be affected.

It doesn't really matter what hypervisor software you use.  We've used 
ESXi, Xencenter and XCP-ng and they all work fine.  Our current 
preference is for XCP-ng because it provides live migration of VMs on 
local disk storage without a license (XC and ESXi both need a license 
for this).

It would be a good idea to use two physically identical servers for the 
hypervisor, so that you can use services like VM migration and 
live-migration.  For disk storage, we'd recommend RAID with battery 
backup, so that you can add or replace physically failed disks easily.

One thing that does matter is disk I/O on the sflow server - if you have 
anything more than about 30 IXP participants, then you need SSD to 
handle the iops.
