存储空间直通(仅限 Windows Server 2019)Storage Spaces Direct (Windows Server 2019 only)

Windows Server 2019 中的存储空间直通有很多改进(存储空间直通不包含在 Windows Server 中,半年频道):There are a number of improvements to Storage Spaces Direct in Windows Server 2019 (Storage Spaces Direct isn't included in Windows Server, Semi-Annual Channel):

  • 用于 ReFS 卷的重复数据删除和压缩Deduplication and compression for ReFS volumes

    对 ReFS 文件系统的重复数据删除和压缩,最多可存储同一个卷上的10倍多的数据。Store up to ten times more data on the same volume with deduplication and compression for the ReFS filesystem. 只需单击一下即可打开 Windows 管理中心。)具有可选压缩的可变大小的区块存储最大限度地提高了节约率,而多线程后处理结构则会使性能影响降至最低。(It's just one click to turn on with Windows Admin Center.) The variable-size chunk store with optional compression maximizes savings rates, while the multi-threaded post-processing architecture keeps performance impact minimal. 支持最大为 64 TB 的卷,并将删除重复每个文件的前 4 TB。Supports volumes up to 64 TB and will deduplicate the first 4 TB of each file.

  • 持久性内存的本机支持Native support for persistent memory

    利用针对持久性内存模块的本机存储空间直通支持释放前所未有的性能,包括 Intel® Optane™ DC PM 和 NVDIMM-N。Unlock unprecedented performance with native Storage Spaces Direct support for persistent memory modules, including Intel® Optane™ DC PM and NVDIMM-N. 将持久性内存用作缓存以提高活动工作集的速度,或用作容量以保证一致的微秒数量级低延迟。Use persistent memory as cache to accelerate the active working set, or as capacity to guarantee consistent low latency on the order of microseconds. 就像在 PowerShell 或 Windows Admin Center 中管理任何其他驱动器一样管理持久性内存。Manage persistent memory just as you would any other drive in PowerShell or Windows Admin Center.

  • 边缘处双节点超融合基础设施的嵌套复原Nested resiliency for two-node hyper-converged infrastructure at the edge

    利用从 RAID 5+1 获得启发的全新软件复原选项,一次可承受两个硬件故障。Survive two hardware failures at once with an all-new software resiliency option inspired by RAID 5+1. 利用嵌套复原,两个节点的存储空间直通群集可以提供应用和虚拟机的连续访问存储,即使一个服务器节点出现故障并且其他服务器节点中一个驱动器出现故障也可继续工作。With nested resiliency, a two-node Storage Spaces Direct cluster can provide continuously accessible storage for apps and virtual machines even if one server node goes down and a drive fails in the other server node.

  • 使用 U 盘作为见证的双服务器群集Two-server clusters using a USB flash drive as a witness

    使用连接到路由器的低成本 USB 闪存驱动器在两个服务器群集中充当见证服务器。Use a low-cost USB flash drive plugged into your router to act as a witness in two-server clusters. 如果服务器关闭然后备份,则 USB 驱动器群集将知道哪个服务器具有最新的数据。If a server goes down and then back up, the USB drive cluster knows which server has the most up-to-date data. 有关详细信息,请参阅Microsoft 博客上的存储For more info, see the Storage at Microsoft blog.

  • Windows Admin CenterWindows Admin Center

    利用新的专门构建的仪表板和 Windows Admin Center 中的体验,管理和监视存储空间直通。Manage and monitor Storage Spaces Direct with the new purpose-built Dashboard and experience in Windows Admin Center. 只需单击几下,即可创建、打开、展开或删除卷。Create, open, expand, or delete volumes with just a few clicks. 监视从整体群集到单个 SSD 或 HDD 的性能,例如 IOPS 和 IO 延迟。Monitor performance like IOPS and IO latency from the overall cluster down to the individual SSD or HDD. Windows Server 2016 和 Windows Server 2019 上均提供,并且无需支付额外费用。Available at no additional cost for Windows Server 2016 and Windows Server 2019.

  • 性能历史记录Performance history

    通过内置历史记录可轻松了解资源利用率和性能。Get effortless visibility into resource utilization and performance with built-in history. 将自动收集跨越计算、内存、网络和存储的 50 多个基本计数器并将其存储在群集上,存储时间长达一年。Over 50 essential counters spanning compute, memory, network, and storage are automatically collected and stored on the cluster for up to one year. 最重要的是,无需安装、配置或启动,只需运行即可。Best of all, there's nothing to install, configure, or start – it just works. 在 Windows Admin Center 中可视化或在 PowerShell 中查询和处理。Visualize in Windows Admin Center or query and process in PowerShell.

  • 纵向扩展到每个群集 4 PBScale up to 4 PB per cluster

    实现多 PB 的扩展 – 非常适合介质、备份和存档用例。Achieve multi-petabyte scale – great for media, backup, and archival use cases. 在 Windows Server 2019 中,存储空间直通支持每个存储池多达 4 拍字节 (PB) = 4,000 太字节的原始容量。In Windows Server 2019, Storage Spaces Direct supports up to 4 petabytes (PB) = 4,000 terabytes of raw capacity per storage pool. 还增加了相关容量指南:例如,你可以创建两倍多的卷(64 而不是 32),每个都是之前的两倍大(64TB 而不是 32TB)。Related capacity guidelines are increased as well: for example, you can create twice as many volumes (64 instead of 32), each twice as large as before (64 TB instead of 32 TB). 将多个群集汇聚到一个群集集中,甚至能在一个存储命名空间内扩大规模。Stitch multiple clusters together into a cluster set for even greater scale within one storage namespace. 有关详细信息,请参阅Microsoft 博客上的存储For more info, see the Storage at Microsoft blog.

  • 镜像加速奇偶校验速度是原来的 2 倍Mirror-accelerated parity is 2X faster

    使用镜像加速奇偶校验,你可以创建存储空间直通卷,这些卷一部分是镜像,另一部分是奇偶校验(如混合使用 RAID 1 和 RAID 5/6),从而充分利用两者的优势。With mirror-accelerated parity you can create Storage Spaces Direct volumes that are part mirror and part parity, like mixing RAID-1 and RAID-5/6 to get the best of both. (它比你在 Windows 管理中心中想像的更容易。)在 Windows Server 2019 中,由于优化,镜像加速奇偶校验的性能比 Windows Server 2016 更多两倍。(It's easier than you think in Windows Admin Center.) In Windows Server 2019, the performance of mirror-accelerated parity is more than doubled relative to Windows Server 2016 thanks to optimizations.

  • 驱动器延迟异常检测Drive latency outlier detection

    通过主动监视和内置离群值检测,轻松识别具有异常延迟的驱动器,这是 Microsoft Azure 的长期方法和成功方法。Easily identify drives with abnormal latency with proactive monitoring and built-in outlier detection, inspired by Microsoft Azure's long-standing and successful approach. 无论是平均延迟还是更微妙的内容(如 99% 百分位的延迟),都将在 PowerShell 中自动标记慢速驱动器,并在 Windows 管理中心中自动标记为 "异常延迟" 状态。Whether it's average latency or something more subtle like 99th percentile latency that stands out, slow drives are automatically labeled in PowerShell and Windows Admin Center with ‘Abnormal Latency' status.

  • 手动分隔卷的分配以提高容错能力Manually delimit the allocation of volumes to increase fault tolerance

    这使管理员能够在存储空间直通中手动分隔卷的分配。This enables admins to manually delimit the allocation of volumes in Storage Spaces Direct. 这样做可能会在某些情况下显著增加容错能力,但会带来一些额外的管理注意事项和复杂性。Doing so can significantly increase fault tolerance under certain conditions, but imposes some added management considerations and complexity. 有关详细信息,请参阅分隔卷的分配For more info, see Delimit the allocation of volumes.

存储副本Storage Replica

存储服务质量Storage Quality of Service

现在可以使用存储服务质量 (QoS) 来集中监控端到端存储性能,并使用 Windows Server 2016 中的 Hyper-V 和 CSV 群集创建策略。You can now use storage quality of service (QoS) to centrally monitor end-to-end storage performance and create management policies using Hyper-V and CSV clusters in Windows Server 2016.

这一更改增添了什么价值?What value does this change add?
你现在可以在 CSV 群集上创建存储 QoS 策略,并将它们分配给 Hyper-V 虚拟机上的一个或多个虚拟磁盘。You can now create storage QoS policies on a CSV cluster and assign them to one or more virtual disks on Hyper-V virtual machines. 存储性能将随工作负载和存储负载波动自动重新调整以符合策略。Storage performance is automatically readjusted to meet policies as the workloads and storage loads fluctuate.

  • 每个策略可以指定保留(最小)和/或限制(最大),以应用于数据流集合,例如虚拟硬盘、单个虚拟机或虚拟机组、服务或租户的集合。Each policy can specify a reserve (minimum) and/or a limit (maximum) to be applied to a collection of data flows, such as a virtual hard disk, a single virtual machine or a group of virtual machines, a service, or a tenant.
  • 使用 Windows PowerShell 或 WMI 可以执行以下任务:Using Windows PowerShell or WMI, you can perform the following tasks:
    • 在 CSV 群集上创建策略。Create policies on a CSV cluster.
    • 枚举 CSV 群集上的可用策略。Enumerate policies available on a CSV cluster.
    • 将策略分配给 Hyper-V 虚拟机的虚拟硬盘。Assign a policy to a virtual hard disk of a Hyper-V virtual machine.
    • 监控每个流的性能和策略中的状态。Monitor the performance of each flow and status within the policy.
  • 如果多个虚拟硬盘共享同一策略,性能将进行公平分配,在策略的最小和最大设置内满足需求。If multiple virtual hard disks share the same policy, performance is fairly distributed to meet demand within the policy's minimum and maximum settings. 因此,策略可用于管理一个虚拟硬盘、一个虚拟机、构成服务的多个虚拟机或租户拥有的所有虚拟机。Therefore, a policy can be used to manage a virtual hard disk, a virtual machine, multiple virtual machines comprising a service, or all virtual machines owned by a tenant.

工作原理的不同之处是什么?What works differently?
此功能是 Windows Server 2016 的新增功能。This capability is new in Windows Server 2016. 管理最小预留,通过单个命令监视跨群集的所有虚拟磁盘流,在早期版本的 Windows Server 中无法实现基于策略的集中式管理。Managing minimum reserves, monitoring flows of all virtual disks across the cluster via a single command, and centralized policy based management were not possible in previous releases of Windows Server.

在到默认的 Active Directory 域服务 SYSVOL 和 NETLOGON 的 Windows 10 和 Windows Server 2016 客户端连接中,域控制器上的共享现在要求 SMB 签名和相互身份验证(例如 Kerberos)。In Windows 10 and Windows Server 2016 client connections to the Active Directory Domain Services default SYSVOL and NETLOGON shares on domain controllers now require SMB signing and mutual authentication (such as Kerberos).

这一更改增添了什么价值?What value does this change add?
此更改降低了中间人攻击的可能性。This change reduces the likelihood of man-in-the-middle attacks.

工作原理的不同之处是什么?What works differently?
如果 SMB 签名和相互身份验证都不可用,Windows 10 或 Windows Server 2016 计算机不会处理基于域的组策略和脚本。If SMB signing and mutual authentication are unavailable, a Windows 10 or Windows Server 2016 computer won't process domain-based Group Policy and scripts.

备注

这些设置的注册表值默认情况下并不出现,但在被组策略或其他注册表值替代前,强化规则仍然适用。The registry values for these settings aren't present by default, but the hardening rules still apply until overridden by Group Policy or other registry values.

工作文件夹Work Folders

改进了工作文件夹服务器运行 Windows Server 2016 和工作文件夹客户端时的更改通知。Improved change notification when the Work Folders server is running Windows Server 2016 and the Work Folders client is Windows 10.

这一更改增添了什么价值?What value does this change add?
对于 Windows Server 2012 R2,当文件更改同步到工作文件夹服务器上时,不向客户端通知这一更改并等待 10 分钟获取更新。For Windows Server 2012 R2, when file changes are synced to the Work Folders server, clients are not notified of the change and wait up to 10 minutes to get the update. 使用 Windows Server 2016 时,工作文件夹服务器会立即通知 Windows 10 客户端,文件更改会立即同步。When using Windows Server 2016, the Work Folders server immediately notifies Windows 10 clients and the file changes are synced immediately.

工作原理的不同之处是什么?What works differently?
此功能是 Windows Server 2016 的新增功能。This capability is new in Windows Server 2016. 这需要 Windows Server 2016 工作文件夹服务器和客户端必须是 Windows 10。This requires a Windows Server 2016 Work Folders server and the client must be Windows 10.

如果你使用的是较旧客户端或工作文件夹服务器为 Windows Server 2012 R2,则客户端将继续每 10 分钟轮询一次更改。If you're using an older client or the Work Folders server is Windows Server 2012 R2, the client will continue to poll every 10 minutes for changes.
