Why I moved to VMWare 為何我換成VMWare

I installed XenServer last year (2011/07), because it is fast and free. Before that, I had tried Hyper-V 2.0 Server,it's slower than XenServer.

Last month, I wanted to add a FreeBSD vm and got bad experience. Another problem, it is very hard to modify vm setting on XenServer.
My boss asked me to do server 100% virtualized, I had to search better solution.
After googling a few hours, I decided to move to VMWare vSphere.

Why? Because I need FreeBSD vm tools installed to get more control, besides I found VMWare Essentials Plus Kits,it's not as expensive as I thought.

Then I installed a test vm server, it's amazing! ESXi 5 Server gave me a whole new experience. It's fast and powerful, with so many APIs and 3rd party tools.

Now, I got very good vm hosts, a stable and fast environment.  Thanks VMWare, I can work easier.

去年評估虛擬化Server後採用XenServer,使用一年也沒有什麼大事,但是支援的作業系統太少始終是個遺憾。會採用XenServer而不用Hyper-V 2.0除了Hyper-V的Linux支援度差外,另一個重要原因是效能不夠好。

主管和我說要讓伺服器100%虛擬化,包括我目前使用的FreeBSD Mail Server,所以只好只找solution。

原本對Hyper-V 3.0滿心期待,但是經過測試後,雖然說功能很強,但是效能遠不如XenServer,所以還是出局。

目前市場上的VM Server,也只剩下VMWare vSphere ESXi支援FreeBSD,幾經探訪才知道有VMWare Essentials Plus Kits的套裝售價,廠商報價不到30萬台幣,對小公司來說還可以負擔,只是我對192GB的限制有些不滿,用ESXi 4.1還有256GB,怎麼到ESXi 5.0反而縮水了?

於是拿我原本測試Hyper-V 3.0的PC來安裝VMWare ESXi 5.0,結果還超出我的預期!免費版有1 CPU unlimited cores、32Gb的限制,但對測試機來說太夠了。

安裝簡單就不提了,看看我的測試環境:
主機不過是台Acer的商用PC,我自掏腰包加到8GB RAM,以及兩張Realtek 8169  1GB網卡。Storage是向JCNet借來的nexenta storage server,提供iSCSI服務。

由以下這兩個VM的資源圖可以看出,在閒置時Active的CPU和Memory其實很少。

另一個值得讚賞的是VMWare Converter,轉換後自動安裝VM Tools,之後要來測FreeBSD,成功後會再另外貼文。

我記得ESXi 5.0 還沒有 FreeBSD 9 的 vmtools, 須要的話要自已重編.

衝著你這句,我寫了一篇

後來 ESXi 5.1就支援FreeBSD 9
