Integrated Virtualization 虛擬伺服器

Virtualization虛擬伺服器是世界上最老的多工運算方式.

最早發現於1960年運行於大型主機,然而這樣的技術在現在卻被用在 高可用性的系統備援與效率提昇上

其中在 Xen 一個Linux Open Source為開發基礎的虛擬伺服器. Xen 虛擬伺服器可運行於市面上幾乎所有的硬體都能夠支援,並且在建置Xen虛擬伺服器架構後立即獲得不可思異的投資報籌率.

Xen虛擬伺服器能夠帶給企業那些好處呢:

• 有效發揮現有硬體的投資與效率
• 增加資源可用性,即使面臨服務移轉也不需要有所中斷
• 增加平衡負載率,有效的提昇各關鑑服務的運作效能
• Xen可以作為實體與虛擬的伺服器資源轉換
• 讓應用程式跨過不多平臺的支援

SUSE Linux Enterprise Server 10 is the first enterprise-class Linux server to:

• Fully support Xen 3.0 virtualization on both 32- and 64-bit x86-based architectures
• Offer support for both paravirtualization through the Xen hypervisor and full virtualization support through partners like VMware for Xen 3.0
• Support both Intel* VT and AMD-V chipsets. In fact SUSE Linux Enterprise Server 10 is the first operating system of any type to support Intel VT and AMD-V.
• Offer fully graphical and command-line virtual machine management tools for easy VM administration and configuration.
