前几代虚拟机大小Previous generations of virtual machine sizes
本部分提供了有关先前几代虚拟机大小的信息。This section provides information on previous generations of virtual machine sizes. 这些大小仍可使用，但有新的大小可供使用。These sizes can still be used, but there are newer generations available.
F 系列F-series
F 系列基于 2.4 GHz Intel Xeon® E5-2673 v3 (Haswell) 处理器，该处理器使用 Intel Turbo Boost 技术 2.0，可实现高达 3.1 GHz 的时钟速度。F-series is based on the 2.4 GHz Intel Xeon® E5-2673 v3 (Haswell) processor, which can achieve clock speeds as high as 3.1 GHz with the Intel Turbo Boost Technology 2.0. 此 CPU 性能与 Dv2 系列的 VM 相同。This is the same CPU performance as the Dv2-series of VMs.
对于需要更快的 CPU，但是每个 vCPU 不需要太多内存或临时存储的工作负荷来说，F 系列 VM 是一个极佳选择。F-series VMs are an excellent choice for workloads that demand faster CPUs but do not need as much memory or temporary storage per vCPU. 诸如分析、游戏服务器、Web 服务器和批处理等工作负荷从 F 系列的优势中获益。Workloads such as analytics, gaming servers, web servers, and batch processing will benefit from the value of the F-series.

Mbps = 每秒 10^6 字节，GiB = 1024^3 字节。MBps = 10^6 bytes per second, and GiB = 1024^3 bytes.
1 Fs 系列 VM 可能的最大磁盘吞吐量（IOPS 或 Mbps）可能受限于附加磁盘的数量、大小和条带化。1 The maximum disk throughput (IOPS or MBps) possible with a Fs series VM may be limited by the number, size, and striping of the attached disk(s). 有关详细信息，请了解如何为 Windows 或 Linux 进行面向高性能的设计。For details, see designing for high performance for Windows or Linux.
大小表定义Size table definitions
存储容量的单位为 GiB 或 1024^3 字节。Storage capacity is shown in units of GiB or 1024^3 bytes. 比较以 GB（1000^3 字节）为单位的磁盘与以 GiB（1024^3 字节）为单位的磁盘时，请记住以 GiB 为单位的容量数显得更小。When you compare disks measured in GB (1000^3 bytes) to disks measured in GiB (1024^3) remember that capacity numbers given in GiB may appear smaller. 例如，1023 GiB = 1098.4 GB。For example, 1023 GiB = 1098.4 GB.
磁盘吞吐量的单位为每秒输入/输出操作数 (IOPS) 和 MBps，其中 MBps = 10^6 字节/秒。Disk throughput is measured in input/output operations per second (IOPS) and MBps where MBps = 10^6 bytes/sec.
数据磁盘可以在缓存或非缓存模式下运行。Data disks can operate in cached or uncached modes. 对于缓存数据磁盘操作，主机缓存模式设置为 ReadOnly 或 ReadWrite。For cached data disk operation, the host cache mode is set to ReadOnly or ReadWrite. 对于非缓存数据磁盘操作，主机缓存模式设置为 None。For uncached data disk operation, the host cache mode is set to None.
若要获得 VM 的最佳性能，应将数据磁盘数限制为每 vCPU 2 个磁盘。If you want to get the best performance for your VMs, you should limit the number of data disks to two disks per vCPU.
预期的网络带宽是指跨所有 NIC 为每个 VM 类型分配的最大聚合带宽，适用于所有目标。Expected network bandwidth is the maximum aggregated bandwidth allocated per VM type across all NICs, for all destinations. 有关详细信息，请参阅虚拟机网络带宽。For more information, see Virtual machine network bandwidth.
无法保证上限。Upper limits aren't guaranteed. 限值用于在为目标应用程序选择适当的 VM 类型时提供指导。Limits offer guidance for selecting the right VM type for the intended application. 实际的网络性能将取决于多种因素，包括网络拥塞、应用程序负载和网络设置。Actual network performance will depend on several factors including network congestion, application loads, and network settings. 有关如何优化网络吞吐量的信息，请参阅为 Azure 虚拟机优化网络吞吐量。For information on optimizing network throughput, see Optimize network throughput for Azure virtual machines. 若要在 Linux 或 Windows 中达到预期的网络性能，可能需要选择特定版本，或者需要优化 VM。To achieve the expected network performance on Linux or Windows, you may need to select a specific version or optimize your VM. 有关详细信息，请参阅带宽/吞吐量测试 (NTTTCP)。For more information, see Bandwidth/Throughput testing (NTTTCP).
