内存优化虚拟机大小Memory optimized virtual machine sizes

内存优化 VM 大小提供适用于关系数据库服务器、中到大型规模的缓存和内存中分析的高内存 CPU 比率。Memory optimized VM sizes offer a high memory-to-CPU ratio that are great for relational database servers, medium to large caches, and in-memory analytics. 本文介绍了此分组中各个大小的 vCPU 数、数据磁盘数、NIC 数、存储吞吐量及网络带宽的相关信息。This article provides information about the number of vCPUs, data disks and NICs as well as storage throughput and network bandwidth for each size in this grouping.

  • M 系列提供高 vCPU 计数(最多 128 个vCPU)和大量内存(最高 3.8 TiB)。The M-Series offers a high vCPU count (up to 128 vCPUs) and a large amount of memory (up to 3.8 TiB). 它非常适用于极大型数据库或受益于高 vCPU 计数和大量内存的其他应用程序。It's ideal for extremely large databases or other applications that benefit from high vCPU counts and large amounts of memory.

  • Dv2 系列和对应的 DSv2 系列是要求更快速 vCPU、更佳临时存储性能或具有更高内存需求的应用程序的最佳选择。Dv2-series, and the DSv2 counterparts are ideal for applications that demand faster vCPUs, better temporary storage performance, or have higher memory demands. 它们为许多企业级应用程序提供强大的组合。They offer a powerful combination for many enterprise-grade applications.

  • Dv2 系列是原 D 系列的后续系列,其特点是 CPU 功能更强大。Dv2-series, a follow-on to the original D-series, features a more powerful CPU. Dv2 系列 CPU 比 D 系列 CPU 快大约 35%。The Dv2-series CPU is about 35% faster than the D-series CPU. 它基于最新一代的 2.4 GHz Intel Xeon® E5-2673 v3 2.4 GHz (Haswell) 或 E5-2673 v4 2.3 GHz (Broadwell) 处理器,通过英特尔睿频加速技术 2.0 可以达到 3.1 GHz。It is based on the latest generation 2.4 GHz Intel Xeon® E5-2673 v3 2.4 GHz (Haswell) or E5-2673 v4 2.3 GHz (Broadwell) processors, and with the Intel Turbo Boost Technology 2.0, can go up to 3.1 GHz. Dv2 系列的内存和磁盘配置与 D 系列相同。The Dv2-series has the same memory and disk configurations as the D-series.

  • Ev3 系列在超线程配置中采用 E5-2673 v4 2.3 GHz (Broadwell) 处理器,针对最常规用途的工作负荷提供了更好的价值主张,因此 Ev3 适用于大多数其他云的常规用途 VM。The Ev3-series features the E5-2673 v4 2.3 GHz (Broadwell) processor in a hyper-threaded configuration, providing a better value proposition for most general purpose workloads, and bringing the Ev3 into alignment with the general purpose VMs of most other clouds. 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,内存也得到了扩展(从 7 GiB/vCPU 到 8 GiB/vCPU)。Memory has been expanded (from 7 GiB/vCPU to 8 GiB/vCPU) while disk and network limits have been adjusted on a per core basis to align with the move to hyperthreading. Ev3 是 D/Dv2 系列的高内存 VM 大小产品的后继产品。The Ev3 is the follow up to the high memory VM sizes of the D/Dv2 families.

  • Azure 计算提供独立于特定硬件类型并专用于单个客户的虚拟机大小。Azure Compute offers virtual machine sizes that are Isolated to a specific hardware type and dedicated to a single customer. 这些虚拟机大小非常适合于与其他客户的工作负载(涉及符合性和法规要求等元素)高度隔离的工作负载。These virtual machine sizes are best suited for workloads that require a high degree of isolation from other customers for workloads involving elements like compliance and regulatory requirements. 客户还可以选择利用对嵌套虚拟机的 Azure 支持,对这些独立的虚拟机资源进一步细分。Customers can also choose to further subdivide the resources of these Isolated virtual machines by using Azure support for nested virtual machines. 请参阅下面的虚拟机系列表,了解独立 VM 选项。Please see the tables of virtual machine families below for your isolated VM options.

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)为单位的磁盘和以 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 comparing 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 GBFor 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 2 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. 不保证能够达到上述预期上限,但目的是提供相关指导,以便为目标应用程序选择适当的 VM 类型。Upper limits are not guaranteed, but are intended to provide guidance for selecting the right VM type for the intended application. 实际的网络性能将取决于许多因素,包括网络拥塞、应用程序负载和网络设置。Actual network performance will depend on a variety of 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 Windows 和 Linux 优化网络吞吐量For information on optimizing network throughput, see Optimizing network throughput for Windows and Linux. 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, it may be necessary to select a specific version or optimize your VM. 有关详细信息,请参阅如何针对虚拟机吞吐量进行可靠的测试For more information, see How to reliably test for virtual machine throughput.
