I have three identical servers, let's call them server1, server2 and server3. RAM, CPUs everything but the storage is identical.
Currently server1 has a RAID 10 of 8 SSDs. This is a development server that hosts in progress VMs and LXCs until they are ready to move to production.
Server2 and server3 each have a single SSD (300GB) using DRBD for VMs. They also each have 2x64GB SSDs mirrored for LXC containers. These are the production servers.
Would you set it up any differently? The virtual machines and containers are internal services (dns, dhcp, etc. ) and webservices (websites, web applications, etc. ).
I'm confident with how I have development setup. Production I'm not so sure.
The idea is to keep production high availability. Assume redundant powers supplied, circuits, UPS and regular backups (which we have).
Hopefully this explains clearly the setup. Any feedback is appreciated.
