完整验证过的架构 完成了很多复杂的软件和硬件集成的可用性可靠性的验证 * * * SRE Virtualization (SRE-V) is VMware vSphere Hypervisor, formerly known as ESXi, optimized for the SRE blades. As a bare-metal hypervisor it provides the following functions: It runs directly on the SRE hardware, there is no other software layer in between It acts as virtual hardware to operating systems running on the hypervisor. The abstraction is transparent and the operating systems do not know they are running on virtual hardware The hypervisor can run multiple operating systems concurrently by controlling hardware resource allocation Each virtual machine is assigned specific amount of disk, CPU, and memory and the hypervisor enforces these allocations The hypervisor can capture entire point-in-time operating system and application state in few flat files and can restore the operating system from these files Because entire state of the system is encapsulated in simple files and the hardware is virtual, these files can be copied and run on any other physical machine with the same hypervisor Following are the specific details on the vSphere Hypervisor: The first release of SRE-V is equivalent to vSphere Hypervisor 4.1, subsequent releases will follow VMware release schedule The hypervisor has been optimized for the SRE blade to allow features like management through a serial console From feature perspective, the hypervisor has been tailored for the branch environment that have only few servers – advanced features like vSphere Distributed Resource Scheduling (DRS) have been disabled to reclaim hardware resources SRE-V is equivalent to the vSphere Essentials license provided by VMware By default SRE-V comes without vCenter management agent support, however this can be enabled through a separate license Unlike many other branch virtualization solutions, SRE-V powered by VMware vSphere Hypervisor Is enterprise- and production-class virtual server platform powering thousands of data centers Provides the most widely-deployed
