|
<p>嗯哼，也就是一般技術支援的信件內容啊，有啥奇怪的？？</p>
|
|
|
|
|
|
<p>重點是，這封信件根本就不是我發出的技術支援申請啊！</p>
|
|
|
|
|
|
<p>一開始我沒當一回事，想說他們自己搞錯了，應該會發現吧</p>
|
|
|
|
|
|
<p>結果三天後，又發了一封信來跟我確認問題是否已經解決。</p>
|
|
|
|
|
|
<p>這次我受不了了，所以有回信給他們說這不是我發出的信件！</p>
|
|
|
|
|
|
<p>我回信後隔天，群暉的人回信致歉了，想說事情告一段落了。</p>
|
|
|
|
|
|
<p>結果，5/31 又來一次，這次是不同的客戶反應的問題。

I think in this configuration there is no possibility to try something with a spare HDD, since all 4 drives are already parts of the one array that exists. We have used exactly the same configuration with the previous Firmware, where the speeds has been in the 35-40 MB range for the block based LUNs.

Prior to the upgrade i achieved “normal” write rates to the 1 TB block based LUN. With DSM 4.0 however the write speed seems to be very limited, also read rate is not the best (or as it was with DSM 3.2). The volume is formatted as VMFS 3.46. When i create another LUN, this time a file based one (no thin provisioning) the write speed seems to be “normal” again, for a file based LUN.Read and write speeds with ESX server are as following:
|
|
|

|
|
|

|
|

|

|

|
|
|
> file based LUN read: 36 MB/sec
|
|
|
>
|
|
|
> file based LUN write: 39 MB/secFurthermore i detected another similar problem: when i use a disk based LUN formatted as NTFS on a Windows 2003 R2 server the write speeds also seem not to be very good. I did another test with a file based and a block based LUN:Read and write speeds with Windows server 2003 R2, NTFS:

|

|
|
|

|
|

<p>6/4才又收到信件說抱歉。然後，6/18我又收到這種信件了。</p>
|
|

<p>接下來總算都沒收到類似的郵件，我也就慢慢忘了這個問題。</p>

<p>我實在很難接受這樣規模的一家公司，可以一而再再而三的發生這種錯誤。</p>
