主要優點Key benefits

簡單。Simplicity. 請從業界標準伺服器執行 Windows Server 2016 到儲存空間直接存取您第一次叢集在 15 分鐘的時間。Go from industry-standard servers running Windows Server 2016 to your first Storage Spaces Direct cluster in under 15 minutes. System Center 使用者部署是一個核取方塊。For System Center users, deployment is just one checkbox.
Unrivaled 的效能。Unrivaled Performance. 是否所有-flash 或混合,儲存空間直接存取輕鬆超過150000 混合 4k 每個伺服器隨機 IOPS使用一致且低延遲感謝其 hypervisor embedded 的架構、建讀取/寫入快取,並支援尖端 NVMe 磁碟機連接上 PCIe 直接。Whether all-flash or hybrid, Storage Spaces Direct easily exceeds 150,000 mixed 4k random IOPS per server with consistent, low latency thanks to its hypervisor-embedded architecture, its built-in read/write cache, and support for cutting-edge NVMe drives mounted directly on the PCIe bus.
容錯。建恢復處理持續可用的磁碟機、伺服器或元件發生問題。 Fault Tolerance. Built-in resiliency handles drive, server, or component failures with continuous availability. 大部署也可以設定為底座及架容錯Larger deployments can also be configured for chassis and rack fault tolerance. 硬體失敗時,只要立即出;軟體治療本身不複雜的管理步驟。When hardware fails, just swap it out; the software heals itself, with no complicated management steps.
資源效率。Resource Efficiency. 清除編碼提供最多 2.4 x 更可以提升儲存效率,例如本機重建驗證碼與 ReFS 即時層延伸到硬碟這些獲得唯一創新功能與混合寒冷熱工作負載所有 CPU 消耗提供降到最低資源回所需之處最-Vm。Erasure coding delivers up to 2.4x greater storage efficiency, with unique innovations like Local Reconstruction Codes and ReFS real-time tiers to extend these gains to hard disk drives and mixed hot/cold workloads, all while minimizing CPU consumption to give resources back to where they're needed most - the VMs.
管理性。Manageability. 使用儲存 QoS 控制項讓過於忙碌 Vm 中檢查下限和上限每一位 VM IOPS 限制。Use Storage QoS Controls to keep overly busy VMs in check with minimum and maximum per-VM IOPS limits. 健康服務提供連續建監視和警示,以及新的 Api 讓您輕鬆收集豐富、整個叢集效能和計量容量。The Health Service provides continuous built-in monitoring and alerting, and new APIs make it easy to collect rich, cluster-wide performance and capacity metrics.

部署選項Deployment options

儲存空間直接存取是設計用兩個不同部署選項:Storage Spaces Direct was designed for two distinct deployment options:


儲存空間及在不同叢集運算。Storage and compute in separate clusters. [聚合型的部署] 選項,也就是 'disaggregated',層級延展檔案伺服器 (SoFS) 在 [儲存空間直接存取網路上的儲存空間提供透過 SMB3 檔案共用。The converged deployment option, also known as 'disaggregated', layers a Scale-out File Server (SoFS) atop Storage Spaces Direct to provide network-attached storage over SMB3 file shares. 這可讓運算日工作負載獨立的儲存空間,例如 HYPER-V IaaS(基礎結構即服務)的大規模部署服務提供者和企業不可或缺的縮放比例。This allows for scaling compute/workload independently from the storage cluster, essential for larger-scale deployments such as Hyper-V IaaS (Infrastructure as a Service) for service providers and enterprises.

儲存空間直接存取可使用另一部伺服器或叢集 HYPER-V Vm 延展檔案伺服器功能的儲存空間


一個叢集運算與儲存空間。One cluster for compute and storage. 超匯集部署選項執行 HYPER-V 虛擬電腦或 SQL Server 資料庫直接提供存放裝置,並儲存在本機磁碟區他們檔案伺服器上。The hyper-converged deployment option runs Hyper-V virtual machines or SQL Server databases directly on the servers providing the storage, storing their files on the local volumes. 這就不需要設定檔案伺服器存取和權限],並減少硬體或成本的小型媒體--商務用 office 日分公司遠端部署。This eliminates the need to configure file server access and permissions, and reduces hardware costs for small-to-medium business or remote office/branch office deployments. 查看使用儲存空間直接存取匯超-集方案See Hyper-converged solution using Storage Spaces Direct.

它的運作方式How it works

儲存空間直接存取是進化版的儲存空間,第一次在 Windows Server 2012 中導入了。Storage Spaces Direct is the evolution of Storage Spaces, first introduced in Windows Server 2012. 它會運用許多您目前在 Windows Server,例如容錯、叢集共用磁碟區 (CSV) 檔案系統、伺服器訊息區 (SMB) 3 當然儲存空間知道的功能。It leverages many of the features you know today in Windows Server, such as Failover Clustering, the Cluster Shared Volume (CSV) file system, Server Message Block (SMB) 3, and of course Storage Spaces. 它也引進了新的技術,尤其是最軟體儲存匯流排。It also introduces new technology, most notably the Software Storage Bus.

以下是儲存空間直接存取堆疊的概觀:Here's an overview of the Storage Spaces Direct stack:


網路功能的硬體。Networking Hardware. 儲存空間直接存取使用 SMB3,包括 SMB 直接與 SMB 多頻道,乙太網路通訊之間的伺服器上。Storage Spaces Direct uses SMB3, including SMB Direct and SMB Multichannel, over Ethernet to communicate between servers. 建議使用的記憶體遠端直接存取 (RDMA),10 + GbE iWARP 或 RoCE。We strongly recommend 10+ GbE with remote-direct memory access (RDMA), either iWARP or RoCE.

儲存空間的硬體。Storage Hardware. 從到本機連接 SATA 16 伺服器 2 SAS 或 NVMe 磁碟機。From 2 to 16 servers with local-attached SATA, SAS, or NVMe drives. 每個伺服器必須至少 2 固態磁碟機,以及至少 4 個額外的磁碟機。Each server must have at least 2 solid-state drives, and at least 4 additional drives. SATA 以及 SAS 裝置應該背後的主機匯流排介面卡 (HBA) 和 SAS 展開工具。The SATA and SAS devices should be behind a host-bus adapter (HBA) and SAS expander. 建議的精心打造且持久工程及廣泛驗證平台從我們的合作夥伴(即將推出)。We strongly recommend the meticulously engineered and extensively validated platforms from our partners (coming soon).

容錯。Failover Clustering. Windows Server 的建叢集功能用來連接伺服器。The built-in clustering feature of Windows Server is used to connect the servers.

軟體儲存匯流排。Software Storage Bus. 儲存空間匯流排軟體中的新儲存空間直接存取。The Software Storage Bus is new in Storage Spaces Direct. 它擴展叢集,並建立軟體定義存放區結構所有伺服器,都查看所有其他的本機磁碟機。It spans the cluster and establishes a software-defined storage fabric whereby all the servers can see all of each other's local drives. 您可以將它替換光纖或共用 SAS 高和嚴格纜。You can think of it as replacing costly and restrictive Fibre Channel or Shared SAS cabling.

儲存空間匯流排層快取。Storage Bus Layer Cache. 軟體儲存匯流排動態繫結的最快速的磁碟機向 (例如 SSD) 提供伺服器端讀取/寫入快取,加速 IO 提升輸送量慢磁碟機 (例如 HDDs)。The Software Storage Bus dynamically binds the fastest drives present (e.g. SSD) to slower drives (e.g. HDDs) to provide server-side read/write caching that accelerates IO and boosts throughput.

儲存集區。Storage Pool. 該從的儲存空間基礎稱為儲存集區的磁碟機的集合。The collection of drives that form the basis of Storage Spaces is called the storage pool. 它就會自動建立,並自動發現並將它所有符合資格的磁碟機。It is automatically created, and all eligible drives are automatically discovered and added to it. 建議一集區每個叢集,使用預設設定。We strongly recommend you use one pool per cluster, with the default settings. 朗讀我們到儲存集區深度剖析以深入了。Read our Deep Dive into the Storage Pool to learn more.

儲存空間。Storage Spaces. 儲存空間提供容錯 virtual,「磁碟」使用鏡像、清除程式設計,或兩者Storage Spaces provides fault tolerance to virtual "disks" using mirroring, erasure coding, or both. 您可以將它按照,軟體定義 RAID 集區中使用的磁碟機。You can think of it as distributed, software-defined RAID using the drives in the pool. 在 [儲存空間直接存取、這些 virtual 磁碟通常有兩個同時磁碟機或伺服器失敗(例如 3 向鏡像,與每個不同的伺服器中的資料複本)恢復但底座,架容錯也會提供。In Storage Spaces Direct, these virtual disks typically have resiliency to two simultaneous drive or server failures (e.g. 3-way mirroring, with each data copy in a different server) though chassis and rack fault tolerance is also available.

使用復原檔案系統 (ReFS)。Resilient File System (ReFS). ReFS 是特殊用途模擬的首要檔案系統。ReFS is the premier filesystem purpose-built for virtualization. 它包括變化萬千加速建立、擴充,並檢查點合併,和建總和檢查偵測及修正的錯誤元.vhdx 檔案作業。It includes dramatic accelerations for .vhdx file operations such as creation, expansion, and checkpoint merging, and built-in checksums to detect and correct bit errors. 也引進了即時層旋轉資料,microsoft 之間「快速鍵」和「冰凍「儲存空間層即時根據使用量。It also introduces real-time tiers that rotate data between so-called "hot" and "cold" storage tiers in real-time based on usage.

叢集共用磁碟區。Cluster Shared Volumes. CSV 檔案系統到所有伺服器,透過單一命名空間統一 ReFS 磁碟區,使每個伺服器,每磁碟區看起來就像是它已在本機裝載。The CSV file system unifies all the ReFS volumes into a single namespace accessible through any server, so that to each server, every volume looks and acts like it's mounted locally.

延展檔案伺服器。Scale-Out File Server. 這一最後的層才能在只聚合型部署。This final layer is necessary in converged deployments only. 它可以使用 SMB3 存取通訊協定,以戶端,例如執行於 HYPER-V 的網路,另一個叢集有效關閉儲存空間直接存取網路上的儲存空間 (NAS) 到遠端檔案存取。It provides remote file access using the SMB3 access protocol to clients, such as another cluster running Hyper-V, over the network, effectively turning Storage Spaces Direct into network-attached storage (NAS).
