[pve-devel] Question about of the future of DRBD9 in PVE

I would like to ask about of the future of DRBD in PVE, so please let me to
explain my setup, my concern, and finally ask a question.
This is my setup:
- I am using DRBD version 8.4.x in PVE.
- Dedicated network for DRBD in bonding "balance-rr" in pairs of network
interfaces, always connected NIC-to-NIC all interfaces of DRBD, several of
these NICs are of 10 Gb/s. for earn more speed.
- Some of these servers has DRBD and a RAID controller with BBU, RAID10,
several HDDs SAS 15K, a fast database in a VM (with a lot of RAM), etc.
These are my concerns:
- The possible problem that i will have (and maybe also much people will
have) is this:
If with the next release of PVE with DRBD9, i can not preserve this same
physical setup of net for DRBD9, perhaps will must to purchase a managed
switch of 10 GB/s for use exclusive in the network connections of DRBD (and
maybe should to purchase 2 managed switch stacked for obtain "HA" in this
net of DRBD).
- The problem is that Switches of 10 GB/s are very expensive.
As i don't have practice with DRBD9, i would like to ask you if can i
preserve this physical setup of net for DRBD9 with the next release of PVE?,
then, avoid the purchase of these expensive new switches, and get that DRBD
working properly in a similar mode to the old version that i was using,
speaking explicitly about of his synchronous replication only between pairs
Awaiting your reply, i say see you soon.
