剛好有個PROJECT要為ESXi準備NAS Storage，所以返復測試了兩者。</p>
<p>今次測試的版本<br />
Openfiler 2.3<br />
FreeNAS 0.7</p>
<p><strong>在驅動方面, 如終是LINUX的Openfiler佔優。</strong><a href="http://www.stephenyeong.idv.hk/wp/wp-content/uploads/2010/01/System-Update.png" rel="lightbox[440]" title="System Update"><img class="size-thumbnail wp-image-446 alignright" title="System Update" src="http://www.stephenyeong.idv.hk/wp/wp-content/uploads/2010/01/System-Update-150x150.png" alt="" width="150" height="150" /></a><br />
因為Openfiler 的Kernel 可以在Web介面上更新，而且想自己Compile Driver 也比較易。<br />
無論在ESX下使用VMXNET3、還是ATOM NanoITX用RTL8111C的JUMBOFRAME支援上，比起使用FreeBSD 7.2的FreeNAS好。</p>
<p>FreeBSD 對於Realtek 8111的jumboframe支援應該要到 FreeBSD 8.0 才能解決。</p>
<p><strong>論功能，FreeNAS 佔優</strong><br />
兩者皆有 iSCSI Target, iSCSI Initiator, NFS, SMB, FTP</p>
<p>但在FTP方面, FreeNAS 佔優。<br />
FreeNAS用proftpd 1.31, 而Openfiler只是proftpd 1.30。雖然版本號相差很少，但可用性就大有不同。<br />
FreeNAS是可以用UTF8的. 用UTF8支援的FTP CLIENT可以見到完整的檔名。而proftpd 1.30 就會出亂碼。</p>
<p>還未計FreeNAS原生有Bittorrent client，基本上可以選定FreeNAS了。</p>
<p><strong>RAID管理，Openfiler LVM+XFS vs FreeNAS ZFS。</strong><br />
在RAID管理方面，Openfiler較強</p>
<p>用到電腦做家用NAS，差不多一定會用RAID。</p>
<p>在空間擴展方面，單以WEB面介面來比較，FreeNAS 較好。因為FreeNAS能用WEB介面使ZFS不斷以Stripe方法擴展。當然Stripe不是真正的RAID。<br />
而Openfiler的Software RAID 只有建立array及加HDD入array為HOT SPARE功能。而且新建的array也不能加到現有的share folder入面。</p>
<p>但Openfiler的優勢是LVM可以在console用指令擴展array.<br />
例如把4碟RAID5加多2碟成為6碟RAID5。</p>
<p>返而FreeNAS的ZFS未能做到。</p>
<p><strong>Finally, LINUX WIN</strong><br />
餘下來的問題是選擇，要功能強大的Openfiler，但沒有UTF8 FTP支援。還是要簡單好用，但RAID未能逹標的FreeNAS?<a href="http://www.stephenyeong.idv.hk/wp/wp-content/uploads/2010/01/proftpd-1.32-on-openfiler.png" rel="lightbox[440]" title="proftpd 1.32 on  openfiler"><img class="size-medium wp-image-445 alignright" title="proftpd 1.32 on  openfiler" src="http://www.stephenyeong.idv.hk/wp/wp-content/uploads/2010/01/proftpd-1.32-on-openfiler-292x300.png" alt="" width="292" height="300" /></a></p>
<p>其實最簡單就要令Openfiler入面的proftpd升給就可以。</p>
<p>設定方法、待續..</p>
