Our client who we want to setup these VM's for is currently using only 50% of allotted resource so considering that fact we plan to setup nodes with below configuration. We plan to setup 4x Core, 16GB Ram, 150GB Disk Space for each VM. And as said earlier we will setup 16VM's on each node with...

Alex, We plan to setup Proxmox in just one one datacenter for now, our plan is to provide High Availability VM's and we are starting with 5x nodes initially with all SSD storage. We would like to create 16x VM's of 150GB Disk Space on each node. I assume if we use Proxmox with KVM we cannot...

Hello Alex, I have option of 2 hardware. Dell R620 with 10x 2.5" Drive Bays and Cisco UCS C240 M3 with 24x 2.5" Drive Bays. Can you suggest a drive configuration and the details of the drives of what they should be used for? Regards, K.Nizam

But many threads I read that Raid with Ceph is not a good option? That's why I was going JBOD route.

Thanks Antoine, so below drive configuration should work fine? 2x Samsung SM863a (Raid 1) for OS and I believe Ceph monitors are also installed here? 8x Samsung SM863a (JBOD Mode) for Ceph OSD's and Journals Regards, K.Nizam

Hello Antoine, We plan to use 2x Arista DCS-7050QX-32S-R in MLAG. I was referring to Proxmox/Ceph install video, which clearly specifies that they recommend fast NVMe SSD drives for OS and Ceph monitors/journals are installed there? Also I read somewhere that it's better to have max 8 OSD per...

Hello Everyone, Our final specs for Proxmox + Ceph cluster will be as below. 2x E5-2660v2 128GB Memory 1x Intel DC P3700 400GB NVMe SSD (For Proxmox OS/Ceph Monitors) 8x 400GB Intel DC S3700 SSD’s (OSD) LSI 9211-8i Controller in JBOD mode. 2x 40Gig Bonded for Ceph Storage Cluster 2x 40Gig...

When I asked production environment with 500+ VM's I didn't mean all 500VM's on a single sever, I meant on the whole proxmox cluster. If we have good CPU's and memory on the nodes there won't be issue to run Ceph and VM's on same node correct? Regards, K.Nizam

Thank you for your comments guys. We definitely would go with everything redundant. Right from power feeds, virtual chassis for switches, power supplies for servers and even network cards on the hypervisors. Some serious suggestion I need whether in production environment with 500+ VM's ceph...

Thank you guys for your feedback. So now we decided we would go with Ceph. When it comes to Proxmox with Ceph do you suggest we keep the Ceph and VM's on same node or should we have separate nodes for Ceph and for VM's? How many networks would we need in total? We would go with 2x 40GbE for...

Thanks Tim. I was under impression that we can do HA setup using ZFS? If we choose Ceph we are certain to go with 2x 40GbE (Bonded) for each node. When choosing Ceph are there any suggestions on type os SSD's to use? We were planning for Samsung Pro SSD's. Regards, K.Nizam

Hello, We are currently selling OpenVZ/KVM VPS to our clients using SolusVM. And its time for us to upgrade our offerings with high availability VPS with inbuilt incremental backup's for our customers. 100% uptime is very IMP for us. If we start with Proxmox we will narrow down our setup purely...
