| 18 | | * Rider 的 GPU on Xen 課程： |
| 19 | | * VMGL 再 VM 上的應用 -> domU 不需分配到顯卡資源，所有的 3D 加速都是透過 dom0來計算，再將結果傳給 domU 的 vmgl 來畫出，彼此間的溝通訊息是透過 VMGl 開啟的通道 (有點像 X server/Client 的概念，dom0 的 VMGL 負責處理影像資料，domU的 VMGL 負責描繪出畫面) |
| 20 | | * CUDA 再 VM 上的應用 -> domU 需得到顯卡資源，再透過 dom0 的 backed driver 來操作顯卡硬體 |

| 22 | | * 裡面有段談到Cloud和Virtualization的關係，原文如下-> Cloud Computing isn’t virtualization or vice versa but '''Cloud Computing creates an excellent platform for virtualization'''. Amazon’s EC2 (Elastic Compute Cloud), for example, is a __Cloud Computing environment (as the name implies) built using Xen__. Alternatively, __Google bases its Cloud environment almost entirely upon physical hardware__. Providers who create Cloud-based environments for public consumption, like Amazon’s EC2, will do so using virtualization due to its '''low cost, flexibility, and high performance'''. |

| 36 | | 2. A Site->mgs*1,oss*3 ， B Site->mgs*1(Second),oss*3 |
| 37 | | 3. A Site->mgs*1,oss*3 ， B Site->mgs*1(獨立),oss*3 ， A和B Site 的 oss 之間用 DRBD 同步，理論上空間最小但效能應該最佳 |
