for calculating an backup server wich should be in worst case
additionaly an virtualisation server we thougth about a setup with
HDDs and for ZFZ chaching NVMes.
We plan all with enterprise products,...
I guess following Setup:
A 12 3,5 '' bay Server, 6 PVEe sockets, maybee with an 2,5'' Rear
entension kit for the OS
4 (or6) HDDs, 6 (or 8) TB without chaching
For virtualisation enviroment:
4 (or6) HDDs, 6 (or 8) TB with NVMe chaching
I think, for the backup enviroment there shouldn't be a chaching
neccessary, cause here is the network the limitation.
The VE part should be a little performer, but how big should the NVMe
cache? As I read, it is for the ZFZ log.
And how much is the performance increasemnt?
