儲存空間直接存取的硬體需求Storage Spaces Direct hardware requirements

適用於︰Windows Server 2016Applies To: Windows Server 2016

本主題說明測試儲存空間直接存取的最低硬體需求。This topic describes minimum hardware requirements for testing Storage Spaces Direct. 建議為生產環境取得 Windows Server 軟體定義硬體/軟體供應項目,其中包括生產環境部署工具和程序。For production environments we recommend acquiring a Windows Server Software-Defined hardware/software offering, which includes production deployment tools and procedures. 這些供應項目經過設計、組合和驗證,符合 Microsoft 的私人雲端環境需求,因此有助於確保作業的可靠性。These offerings are designed, assembled, and validated to meet Microsoft's requirements for private cloud environments, helping ensure reliable operation. Windows Server 軟體定義供應項目在我們的合作夥伴網站中取得。Windows Server Software-Defined offerings are available are our partner websites. 如需我們合作夥伴網站連結及計畫的詳細資訊,請瀏覽:Windows Server 軟體定義資料中心More information about the program and links to our partner websites can be found at: Windows Server Software Defined.

如果您想要評估 Windows Server 2016 的儲存空間直接存取而不投資硬體,可以使用 Hyper-V 虛擬機器,如使用 Windows Server 2016 虛擬機器測試儲存空間直接存取 (英文) 中所述。If you would like to evaluate Storage Spaces Direct in Windows Server 2016 without investing in hardware, you can use Hyper-V virtual machines, as described in Testing Storage Spaces Direct using Windows Server 2016 virtual machines.

基本需求Basic requirements

依照 Windows Server 類別目錄,所有系統、元件、裝置及磁碟機都必須是「Windows Server 2016 認證」。All systems, components, devices, and drivers must be "Certified for Windows Server 2016" per the Windows Server Catalog.

完全設定的叢集 (伺服器、網路及儲存空間) 必須通過容錯移轉叢集嵌入式管理單元中精靈的所有叢集驗證測試,或在 PowerShell 中使用 Test-Cluster Cmdlet。The fully configured cluster (servers, networking, and storage) must pass all cluster validation tests per the wizard in the Failover Cluster snap-in or with the Test-Cluster cmdlet in PowerShell.

此外,亦適用下列需求。In addition, the following requirements apply.

儲存空間直接存取的其他需求Additional requirements for Storage Spaces Direct

伺服器Servers

  • 至少 2 部伺服器,最多不超過 16 部Minimum of 2 servers, maximum of 16 servers
  • 所有伺服器都應該是同一個製造商與型號All servers should be the same make and model

CPUCPU

  • 至少是 Intel Nehalem 或更新版本的相容處理器Minimum of Intel Nehalem or later compatible processor

記憶體Memory

  • 每部伺服器上快取磁碟機容量的每一 TB 有 4 GB RAM,儲存「儲存空間直接存取」中繼資料。4 GB of RAM per terabyte (TB) of cache drive capacity on each server, to store Storage Spaces Direct metadata.
    請注意,RAM 大小使用以 2 為底數的數字 (1 GB = 1024 MB),而磁碟機的通知使用以 10 為底數的數字 (1 TB = 1,000 GB)。Note that RAM sizes use base-2 numbering (where 1 GB = 1,024 MB), while drives are advertised using base-10 numbering (where 1 TB = 1,000 GB). 例如,如果每個伺服器有 2 x 1.6 TB(通告容量)快取磁碟機,您應該保留 2 x 1.6 x 4096 MB = 13,107 MB (12.8 GB) 的記憶體,供儲存空間直接存取內部使用。For example, if each server has 2 x 1.6 TB (advertised capacity) cache drives, you should keep 2 x 1.6 x 4096 MB = 13,107 MB (12.8 GB) of memory available for Storage Spaces Direct internal use.
  • Windows Server、VM,以及其他 app 或工作負載所使用的記憶體。Any memory used by Windows Server, VMs, and other apps or workloads.

網路功能Networking

  • 至少 10 Gbps 網路介面用於叢集內通訊Minimum of 10 Gbps network interface for intra-cluster communication
  • 建議:兩張網路介面卡用於備援及效能Recommended: Two NICs for redundancy and performance
  • 建議:能夠遠端直接記憶體存取 (RDMA) 的 NICS,iWARP 或 RoCERecommended: NICS that are remote-direct memory access (RDMA) capable, iWARP or RoCE

磁碟機Drives

如需選擇磁碟機的說明,請參閱選擇磁碟機主題。For more help choosing drives, see the Choosing drives topic.

  • 使用本機連接的 SATA、SAS 或 NVMe 磁碟機。Use local-attached SATA, SAS, or NVMe drives.
  • 每部磁碟機必須只能實際連接一部伺服器。Every drive must be physically connected to only one server.
  • 所有伺服器必須都具有相同的磁碟機類型 (如果一個伺服器有 NVMe,請參閱,它們都需要 NVMe。All servers must have the same drive types (if one server has NVMe, they all require NVMe. 如果一個有 HDD,它們都需要 HDD)If one has HDD, they all require HDD)
  • 建議:所有伺服器都有相同的磁碟機設定(類型、大小、韌體)Recommended: All servers have the same drive configuration (type, size, firmware)
  • SSD 必須有斷電保護,亦即為「企業級」。SSDs must have power-loss protection, i.e. they are "enterprise-grade"
  • 建議:快取磁碟機必須具有相當高的寫入耐力:每日至少 3 次磁碟機寫入 (DWPD),或每日至少 4 TB 寫入 (TBW)。Recommended: Cache drives must have high write endurance: at least 3 drive-writes-per-day (DWPD) or at least 4 terabytes written (TBW) per day. 若要深入了解,請參閱了解儲存空間直接存取的磁碟機每日寫入 (DWPD)、TB 寫入 (TBW) 和最低建議 (英文)。To learn more, see Understanding drive writes per day (DWPD), terabytes written (TBW), and the minimum recommended for Storage Spaces Direct.
  • 建議:以 NVMe 或 SSD 快取裝置數目的倍數新增容量磁碟機。Recommended: Add capacity drives in multiples of the number of NVMe or SSD cache devices.
  • 磁碟機可以是 512n、512e 或 4K 原生 - 皆運作良好。Drives can be 512n, 512e, or 4K native - they all work equally well.
  • 將獨立的專用磁碟機或 RAID 1 鏡像用於 Windows Server(200 GB 是建議大小下限)。Use a separate, dedicated drive or RAID 1 mirror for Windows Server (200 GB is a recommended minimum size).
  • 不支援:多重路徑 IO (MPIO) 或透過多重路徑實際連接磁碟機。Not supported: Multi-path IO (MPIO) or physically connecting drives via multiple paths.

磁碟機數量下限Minimum number of drives

  • 如有磁碟機用為快取,每部伺服器至少必須 2 部If there are drives used as cache, there must be at least 2 per server
  • 每部伺服器至少必須有 4 個容量 (非快取) 磁碟機There must be at least 4 capacity (non-cache) drives per server

注意

此表格提供裸機部署所需的磁碟機數目下限。This table provides the minimum number of drives required for bare-metal deployments. 如果您正在使用虛擬機器和模擬儲存空間 (例如在 Azure) 部署儲存空間直接存取,則免除此要求,因為「磁碟機」應該永不失敗。If you're deploying Storage Spaces Direct using virtual machines and virtualized storage, such as in Azure, this requirement is waived because your "drives" aren't expected to ever fail. 此時,需求為每部伺服器有兩個「磁碟機」。In this case, the requirement is just two "drives" per server. 在 Azure,我們建議使用 Premium 資料磁碟以獲得較佳的效能。In Azure, we recommend using premium data disks for better performance.

最大值Maximum

  • 每儲存集區不超過 1 PB (1,000 TB) 的未經處理容量Maximum of 1 petabyte (1,000 TB) of raw capacity per storage pool
