Hi,
I have question about optimal DRBD9 SSD setup.
Is HW RAID (with BBU) necessary for SSD pool and DRBD (LSI3108 on SuperMicro motherboard)? Will be performance far better than MDADM raid on normal mobo SATA controller?
I can 2x 800GB in raid1 or maybe 4x400GB raid10, 1x 10GB Base-T direct connection between two nodes.
SSD wil be Intel DC3610. Nodes wil be on UPS.
So HW RAID or MDADM? 1x 10Gbit or better 2x10Gbit for replication?
On this SSD pool I will run mainly DB (PostgreSQL) linux VM.
And I know that DRBD9 is marked as technology prewiev in Proxmox. Is there any chance for production ready state to end of year?
Is there any other recomendation for DRBD with SSD? I read wiki for DRBD9, there is note about hardware raid controller with BBU, but is this still valid for SSD pool?
Thanks,
ZS-Man
