Hello, have a lot of (useless, most of them) posts on this issue here. Problem was always end up with the same problem: the storage. This is all solved now, managed to get a NetApp filer with 12 300GB 15k SAS disks, raidDP, snapshots, deduplication and so on. It is gorgeus.
Problem is I cannot get any hints from Cloudmin GPL as some of these features are PRO.
Now, my gear is:
-1 Cisco SG30028 L2/L3 switch, working in L2 now;
-1 IBM X3650 M2, 24GB DDR3, dual Quad Xeon, 6 10k SAS disks;
-2 HP DL385 G5, 32GB DDR2, dual Quad Opteron, 2 10k SAS disks;
-1 NetApp FAS2020;
- lot of other machines/devices, maybe important I will set a backup NAS storage with 6 x 1TB 7,2k running FreeNAS
I have 2 connections from 2 ISP (no BGP, 3IPs for each one). ns1.xxx.ro (the IBM) on one provider and ns2.xxx.ro (a virtual machine for now) on the other.
Now I am thinking something like this:
-use NFS on the filer, CentOS 6.4 as the OS, KVM for virtualization;
-have to aggregate some nics to get, failover&speed in the internal LAN;
-use the IBM as the machine running all the services and domains with Virtualmin Pro (4 of the drives are a raid5 /home partition, the other 2 in raid1 = the OS);
-use the IBM as the Cloudmin controller, and the HPs as the hosts for a few virtual machines, their /home partitions on the filer; also in case of IBM fail I should be able to quickly (automatically?) to move the domains on the HPs (on the physical host or in a VM, doesn’t matter;
-how can I achieve some Internet connection redundancy in this setup? If one goes down the other connection to take over (DNS involved);
-are there any issues now between the Intel and AMD CPUs regarding the virtual machines? A few years ago all hypervisors had problems migrating a vm from one host to another with a different CPU. Anyway can I keep the IBM out of the VM stuff, just to controll it?
-what should I do (how to setup things to help me) in the case of a controller meltdown ie IBM fail?
-recommended DNS setup?
What would be your thoughts on a “Perfect Cloudmin&Virtualmin Pro Setup with CentOS 6.x”? A “How to Forge” this step-by-step guide would be welcome
