磁碟機Drives

儲存空格直接適用於直接附加 SATA、 SAS 或 NVMe 磁碟機的實體附加至只要一部伺服器。Storage Spaces Direct works with direct-attached SATA, SAS, or NVMe drives that are physically attached to just one server each. 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.

以下是如何磁碟機可以進行連線的儲存空間直接:Here's how drives can be connected for Storage Spaces Direct:

  1. 直接連接的 SATA 磁碟機Direct-attached SATA drives
  2. 直接連接 NVMe 磁碟機Direct-attached NVMe drives
  3. 具有 SAS 磁碟機 SAS 主機匯流排介面卡 (HBA)SAS host-bus adapter (HBA) with SAS drives
  4. 具有 SATA 磁碟機 SAS 主機匯流排介面卡 (HBA)SAS host-bus adapter (HBA) with SATA drives
  5. 不支援: RAID 控制器卡或 SAN (光纖通道 iSCSI、 FCoE) 存放區。NOT SUPPORTED: RAID controller cards or SAN (Fibre Channel, iSCSI, FCoE) storage. 主機匯流排介面卡 (HBA) 卡必須實作簡易的傳遞模式。Host-bus adapter (HBA) cards must implement simple pass-through mode.

支援的磁碟機的圖表連接

磁碟機可以是內部伺服器,或在外部圍繞符號,是連線至只要一部伺服器。Drives can be internal to the server, or in an external enclosure that is connected to just one server. SCSI 圍繞符號服務 (SES) 是必要的插槽對應及識別碼。SCSI Enclosure Services (SES) is required for slot mapping and identification. 每個外部圍繞符號必須呈現的唯一識別碼 (唯一識別碼)。Each external enclosure must present a unique identifier (Unique ID).
