Increasing Server, Storage, and Network Availability: Scenario Overview


Updated: August 24, 2012

Applies To: Windows Server 2012

Server Availability in Windows Server 2012 provides a collection of experiences that are designed to improve availability, performance, and reliability at the single-server and multiple-server (scale-up and scale-out) levels.

The experiences in Server Availability include the following:

  • Improved NTFS availability   Install and configure large volumes that are resilient against downtime caused by potential file corruption.

  • File server for scale-out application data   Deploy server applications, such as Microsoft SQL Server and Hyper-V, on continuously available file servers.

  • Continuously available DHCP service   Improve network availability by using Dynamic Host Configuration Protocol (DHCP) failover services.

  • Network failure resilience   Use Load Balancing and Failover to aggregate bandwidth and maximize network reliability.

  • Continuously available block storage for server applications   Create continuously available block storage for server applications by using iSCSI Transparent Failover.

  • Fast and efficient file servers for server applications   Improve network and file performance by using Remote Direct Memory Access (RDMA) and SMB Direct.

  • Network performance and availability for Windows file servers   Take advantage of all available network bandwidth by using SMB Multichannel.

  • Storage spaces   Enable cost-effective and flexible storage solutions for business critical deployments.

  • Offloaded data transfers   Move data quickly between storage devices by using Offloaded Data Transfer.

  • Storage mobility for virtual machines   Move virtual hard disks to other locations with no downtime.

  • Direct connections for virtualized workloads to Fibre Channel-based storage   Provide server applications with access to Fibre Channel-based storage directly from a guest operating system.

  • Continuously available file servers for heterogeneous environments   Create continuously available Network File System (NFS) file shares by using NFS transparent failover.

  • Data protection   Protect your application data by using SMB Volume Shadow Copy for remote file shares.

  • Hyper-V over SMB   Enable virtual machines to reside on an SMB file shares, giving you the power to design new flexible storage solutions for your virtual or cloud infrastructure.
