I'm mostly using freebsd, but there are a few cases where it's
impossible to do, and because of these, i'm not using fbsd there.
These reasons are mostly are:
- Lack of a working infiniband/OFED stack, with all its utils,
mellanox connectX3 drivers, RDMA, iscsi-over-RDMA, nfs-over-RDMA,
and such things.
- Lack of proper support for a decent hypervisor for virtualisation.
We can't make a hypervisor out of freebsd, if there are no such
virtualisations available like XEN, kvm or something similar, that
just works out of the box.
- Lack of decent OCI support (oracle client lib). Sometimes we need
OCI libs, for things like monitoring oracle databases. Without the
client libs, this becomes kinda problematic.
