[PVE-User] re HBA raid, storage best practices - NFS & iSCSI

We need apparently a block device for online snapshots.
We are by own decision using (by own trial and error) iSCSI under LVM
for our webservers virtual hard drives etc where we need 100% uptime.
This is working fine but is less dynamic for us than NFS.
We did use NFS and the VMs will then by same backup spec use suspend
instead of online meaning they will freeze for like 5 minutes while
backup runs. I don't like that for the less uptime.
For all other storage, for end users, for webhosting space etc we use
NFS for the simplicity of mgmt.
