Dv3 和 Dsv3 系列Dv3 and Dsv3-series

Dv3 系列在采用超线程配置的 Intel® Xeon® Platinum 8272CL (Cascade Lake)、Intel® Xeon® 8171M 2.1GHz (Skylake)、Intel® Xeon® E5-2673 v4 2.3 GHz (Broadwell) 或 Intel® Xeon® E5-2673 v3 2.4 GHz (Haswell) 处理器上运行,为大多数常规用途工作负荷提供更好的价值定位。The Dv3-series run on Intel® Xeon® Platinum 8272CL (Cascade Lake), Intel® Xeon® 8171M 2.1GHz (Skylake), Intel® Xeon® E5-2673 v4 2.3 GHz (Broadwell), or the Intel® Xeon® E5-2673 v3 2.4 GHz (Haswell) processors in a hyper-threaded configuration, providing a better value proposition for most general purpose workloads. 在磁盘和网络限制已基于核心进行了调整以适应超线程技术的同时,内存已扩展(从 ~3.5 GiB/vCPU 到 4 GiB/vCPU)。Memory has been expanded (from ~3.5 GiB/vCPU to 4 GiB/vCPU) while disk and network limits have been adjusted on a per core basis to align with the move to hyperthreading. Dv3 系列不再具有 D/Dv2 系列的高内存 VM 大小,那些已移至内存优化的 Ev3 和 Esv3 系列The Dv3-series no longer has the high memory VM sizes of the D/Dv2-series, those have been moved to the memory optimized Ev3 and Esv3-series.

示例 D 系列用例包括企业级应用程序、关系数据库、内存中缓存和分析。Example D-series use cases include enterprise-grade applications, relational databases, in-memory caching, and analytics.

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 ReadOnlyReadWriteFor 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 NoneFor 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).
