<div class="post__content"><p>前幾天公司的一台 Synology DS 415+ 發生異常</p>
|
|
|
|
|
|
<p>注意到的時候,四顆硬碟燈號都不斷的在閃爍</p>
|
|
|
|
|
|
<p>但是已經無法登入系統</p>
|
|
|
|
|
|
<p>重開機之後更慘,四顆硬碟燈號全部橘燈恆亮</p>
|
|
|
|
|
|
<p>底下的電源藍燈不斷的在閃爍</p>
|
|
|
|
|
|
<p>雖然我一再表示不希望送修了</p>
|
|
|
|
|
|
<p>一來是已經過保,二來是DS415+ 本身就有intel bug,三來是因為對synology的NAS 實在沒有愛…</p>
|
|
|
|
|
|
<p>不過主管還是希望能夠先問群暉維修的費用多少</p></div>

<div class="post__content"><p>想做一個 10G 的 LAB 環境出來已經很久了。</p>
|
|
|
|
|
|
<p>只是礙於10G RJ45的卡太貴了,然後光纖的種類又太複雜</p>
|
|
|
|
|
|
<p>如果直接在淘寶購買,很怕會買錯(什麼LC/FC LC/LC 多模單模 單芯雙芯 SFP/SFP+ 又是什麼光模塊的一大堆規格)</p>
|
|
|
|
|
|
<p>所以一直沒有付諸行動。</p>
|
|
|
|
|
|
<p>硬體的工作很久沒碰了,剛好在蝦皮看到有個賣家在賣 mellanox 的X2網卡,以在台灣的價格來說,算很便宜的 (550)</p>
|
|
|
|
|
|
<p>聊了一下,跟他請教了關於線材、光纖模塊的問題,回答也都很快很到位</p>
|
|
|
|
|
|
<p>就直接下訂了兩張網卡、兩個光纖模塊、一條LC/LC 光纖線</p>
|
|
|
|
|
|
<p>就是到貨有點久,等了兩個禮拜左右,一直到昨天東西才寄到</p>
|
|
|

|
<p>今天就花了點時間測試一下</p></div>

<p>他用圖書館/書本的概念,讓使用者可以建立自己的”圖書館”</p>

|
|

<p>其他的方式像是在nextcloud上編輯 md檔案(字體太小)</p>

<p>Bookstack則是沒有這些問題,不過就是系統「大」了點…</p>

<p>不過還好有人做成docker的方式來啟動,大大的降低了建置的難度(其實也沒有很難啦,只是要裝個PHP、弄個DB而已)</p></div>
