本主题简要概述了 iSCSI 目标服务器,这是 Windows Server 中的一项角色服务,可让你通过 iSCSI 协议提供存储。This topic provides a brief overview of iSCSI Target Server, a role service in Windows Server that enables you to make storage available via the iSCSI protocol. 这对于不能通过本机 Windows 文件共享协议 SMB 进行通信的客户端提供对 Windows server 上存储的访问很有用。This is useful for providing access to storage on your Windows server for clients that can't communicate over the native Windows file sharing protocol, SMB.

iSCSI 目标服务器适合于以下情况:iSCSI Target Server is ideal for the following:

  • 网络和无磁盘启动    通过使用支持启动的网络适配器或软件加载程序,你可以部署数百台无盘服务器。Network and diskless boot   By using boot-capable network adapters or a software loader, you can deploy hundreds of diskless servers. 借助 iSCSI 目标服务器,部署可快速进行。With iSCSI Target Server, the deployment is fast. 在 Microsoft 内部测试中,256 台计算机可在 34 分钟内进行部署。In Microsoft internal testing, 256 computers deployed in 34 minutes. 通过使用差异虚拟硬盘,可以将用于操作系统映像的存储空间节省高达 90%。By using differencing virtual hard disks, you can save up to 90% of the storage space that was used for operating system images. 对于大规模部署完全相同的操作系统映像,如在运行 Hyper-V 的虚拟机上或高性能计算 (HPC) 群集中,这是理想之选。This is ideal for large deployments of identical operating system images, such as on virtual machines running Hyper-V or in high-performance computing (HPC) clusters.

  • 服务器应用程序存储    某些应用程序需要块存储。Server application storage   Some applications require block storage. iSCSI 目标服务器可以为这些应用程序提供连续可用的块存储。iSCSI Target Server can provide these applications with continuously available block storage. 由于此存储可远程访问,它也可以为总部或分支机构办公室位置整合块存储。Because the storage is remotely accessible, it can also consolidate block storage for central or branch office locations.

  • 异类存储    iSCSI 目标服务器支持非 Microsoft iSCSI 发起程序,使你可以轻松地在混合软件环境中的服务器上共享存储。Heterogeneous storage   iSCSI Target Server supports non-Microsoft iSCSI initiators, making it easy to share storage on servers in a mixed software environment.

  • 开发、测试、演示和实验室环境    启用 iSCSI 目标服务器后,运行 Windows Server 操作系统的计算机将成为可通过网络访问的块存储设备。Development, test, demonstration, and lab environments   When iSCSI Target Server is enabled, a computer running the Windows Server operating system becomes a network-accessible block storage device. 这对于在存储区域网络 (SAN) 中进行部署之前测试应用程序非常有用。This is useful for testing applications prior to deployment in a storage area network (SAN).

块存储要求Block storage requirements

使 iSCSI 目标服务器能够提供块存储,从而利用现有以太网网络。Enabling iSCSI Target Server to provide block storage leverages your existing Ethernet network. 不需要额外的硬件。No additional hardware is needed. 如果高可用性是一项重要标准,则考虑设置高可用性集群。If high availability is an important criterion, consider setting up a high-availability cluster. 需要将共享存储用于高可用性群集(光纤通道存储的硬件或串行连接 SCSI (SAS) 存储阵列)。You need shared storage for a high-availability cluster—either hardware for Fibre Channel storage or a serial attached SCSI (SAS) storage array.

如果启用来宾群集,则需要提供块存储。If you enable guest clustering, you need to provide block storage. 运行具有 iSCSI 目标服务器的 Windows Server 软件的任何服务器都可以提供块存储。Any servers running Windows Server software with iSCSI Target Server can provide block storage.
