This article describes how to install FreeBSD on ZFS from installation CD-ROM, with ZFS as root partition.

PREPARATION

You need to prepare a ‘disc1’ of FreeBSD, as well as a ‘LiveFS’ disc. Also, you should be familiar with daily operation of FreeBSD system administration.

In order to use ZFS on FreeBSD, one has to use FreeBSD 7.0 or better. For better stability and performance, you should have at least 1GB of RAM, and preferably running on a CPU which is capable to run FreeBSD/amd64, fortunately, most modern CPUs does support this.

因为我用的网卡多数都是em(4)，所以在最近的升级中也就利用了它提供的TSO功能。TSO是一项减少服务器负载的技术，其原理是将TCP相关的一部分计算交给网卡去做。

被Grim Reaper嚷了40多次，其实有时候觉得这个机制也有它的一些不足。
