Hi there,
it's not a real project (yet), but I would love to build a three node Proxmox/Ceph cluster in my mind and share the design ideas with you to hear your opinion about it.
Here are the requirements:
About 50 server VMs (full virtualization) - most of them windows servers, but also a bunch of linux VMs - will need about 8 TB of fast storage and about 300 GB of RAM. CPU requirements are moderate. Storage and RAM should be easy scalable. A redundancy of 2 would be fine, so 1 out of 3 machines is allowed to die.
I love simple, small and powerful concepts, so this is my hardware suggestion (three identical nodes):
Basis
Thomas Krenn 1HE Intel Dual-CPU RI2108+ Server
https://www.thomas-krenn.com/de/produkte/rack-server/1he-server/intel-dual-cpu/ri2108-plus.html
CPU
1x Intel Xeon® Processor E5-2690 v4 (14 Cores, 2,6 GHz)
RAM
256 GB (8x 32 GB ECC DDR4)
Storage
1x M.2 SSD 128 GB for the operating system and the software
1x 240 GB SSD (Samsung PM863a) for ceph monitor
3x 1,92 TB SSD (Samsung PM863a) as ceph OSDs
Networking
1x Intel X710-DA2 SFP+ Dual Port 10 GBit (1x 10 GBit for the VMs, 1x 10 GBit for Ceph)
(These NICs would be connected to some Juniper EX-3300 switches)
The questions a have at the moment, are:
1. Do you think that the storage backend will perform well? Especially referring to two performance critical Oracle databases and one Windows application server.
2. The mainboard has got some SATA connectors. Would it be fine to connect the SSDs to them, or is it recommended to use an HBA between the SSDs and the mainboard?
3. If anyone knows reliable non-US network cards, let me know. So far I only have experience with Intel stuff.
I'm so curious about your opinion!
Thanks a lot and many greets
Stephan
