最后，还支持在较旧的TL上使用新硬件。
Finally, there is also now support for new hardware on older TLs.
动态迁移(Live migration)允许操作系统及其应用程序迁移到新的服务器上，从而实现负载在可用硬件上的均衡。
Live migration allows an operating system and its applications to be migrated to a new server to balance the load over the available hardware.
在IE9上的硬件加速。
WindowsServer 2008就被设计成这样，因此它清楚何时作为虚拟机运行，何时在物理硬件上运行。
The Windows Server 2008 was designed enlightened so it would know when it is running as a virtual machine and it would know when it is running on physical hardware.
在裸硬件上运行的是系统管理程序(带有KVM模块的Linux内核)。
Running on the bare hardware is the hypervisor (the Linux kernel with the KVM module).
注意：以下更新固件的方法在您所在的地区或硬件上可能不受支持。
Note: The following method of firmware update might not be supported in your area or for your hardware.
如果发生硬件故障，那么部署在故障硬件上的所有服务器都将不能使用。
If a hardware failure occurs, all the servers that are deployed on the failed hardware become unavailable.
作为一个开发人员，这对您意味着在64位硬件上可能会有一些意外发生。
What this means for you as a developer is that you might have some surprises on 64-bit hardware.
在许多情况下，可以购买这些老游戏以在新的硬件上运行。
In many cases, these older games can be purchased to run on newer hardware.
这个游戏在快速的硬件上不会有问题，但你会浪费不少贵重的时钟周期。
The game will have no problems on fast hardware, but you are wasting so many precious clock cycles.
