read a lot in preparation for installing freebsd-10rc5:
preparing a GPT disk and booting into either UFS or ZFS filesystems (for FreeBSD on real hardware); also: what is TRIM on SSDs? and: is it supported i FreeBSD with either UFS (yepp) or ZFS (yepp).
preparing DRBDs and LVMs for clustering proxmox systems (for FreeBSD running as VM); the entire Proxmox "Storage_Model" page; iSCSI = RFC 3720; and a bit more (again) on ProxmoxVE Clustering.
