English to Chinese Tech/Engineering IT (Information Technology) Hyper-V

The final piece of the puzzle of high-speed file sharing is SMB Direct, where Remote Direct Memory Access-capable NICs can provide phenomenal performance for storage access. Improvements inside of Hyper-V -- such as having one I/O channel per 16 vCPUs in the VM (Windows Server 2008 R2 only offered one for entire VM), one I/O queue per SCSI disk (limited in 2008 R2 to one per controller) and I/O Interrupts scaling dynamically across vCPUs instead of using {only one} in previous versions -- all contribute to high levels of performance. Microsoft has demonstrated one million IOPS from a single VM.

高速文件共享方面的最后一部分是SMB Direct，具有远程直接内存访问（RDMA）功能的网卡可提供异常出色的存储访问性能。Hyper-V里面的种种改进都帮助提高了性能级别，比如虚拟机里面每16个虚拟处理器有一条输入/输出通道（Windows Server 2008 R2只为整个虚拟机提供一条输入/输出通道），每只SCSI磁盘一个输入/输出队列（2008 R2中局限于每个控制器一个队列），以及跨虚拟处理器实现输入/输出中断动态扩展，而不是在之前版本中只使用一个XX。微软演示了单个虚拟机可以达到每秒100万次输入/输出操作。

具体是指only one XX？
