Hi all,
Our company is looking for a way to provide VMs and LXC containers to our research staff, and Proxmox looks like it may just be the perfect fit... So I am tasked with taking some spare servers and spinning up a PoC. This rig doesn't have to be very performant, just good enough to demonstrate the principles and do some testing with.
So, what I want to end up with is a 3-node HA cluster using shared storage. The three nodes I have to use were originally sold as "storage servers", each has the following specs:
- CPU: (2) Intel Xeon X5450 @ 3.00GHz (total 8 cores)
- RAM: 24 GB
- Disk: (1) 1TB RAID-1 array (Proxmox OS installed here); (2) 2TB hdd's; (8) 1TB hdd's.
- NICs: (4) 1Gbps
I want to do a "hyperconverged" setup, wherein the shared storage is provided on the hypervisor nodes. (I previously did this sort of setup using oVirt on these nodes, with a Gluster shared filesystem spread across the nodes.) In this case, was thinking of using Ceph as the basis of shared storage (from what I have been reading here, as far as for Proxmox use, Ceph is more commonly used for distributed storage over Gluster, correct?) I know that the lack of 10Gbps network infra is non-optimal as far a Ceph usage, but like I said, this is just a PoC rig, which if the concept proves itself, then we can acquire better hardware for the purpose.
Which brings me to my ask: Is there any "planning guides" etc available for doing this sort of thing? (HA with Ceph shared storage on the same nodes) I have found this on the wiki: https://pve.proxmox.com/wiki/Ceph_Server but I don't know yet (proxmox newb here, just digging in to all this now) if there's a broader overview available on how to lay out the hardware & networking, and then installation and configuration of Proxmox to support this scenario.
Thanks for any info provided,
Will
