Small and Midsize Business Computer Networks: Windows Server 2008 and 2008 R2 Failover Cluster Solutions
Clustering is a key technique to achieve maximum fault tolerance. A cluster is a collection of computer systems responsible for running a shared set of applications and services. The systems in the cluster are interconnected through hardware and software in such a way that in case any component in the cluster stops functioning, the workload will "failover" to, or be assumed by, another system in the cluster without a disruption of service.
Failover clustering clearly has an advantage in increasing network availability in the case of a hardware breakdown, but it also allows non-disruptive system maintenance for environments that have no time window when key applications such as email or web commerce can be taken offline without hurting business. For geographically dispersed environments, multi-site clustering provides insurance against natural disasters such as earthquakes or hurricanes.
The Enterprise and Datacenter editions of Windows Server 2008 included significant improvements in failover clustering such as easier deployment, management, and migration; enhanced support for multi-site clusters; improved security architecture and quorum models; stronger authentication and encryption; and more efficient tools for backup and recovery. Windows Server 2008 R2 offers even more advanced support for clustering through the addition of features that make clusters more secure, more available, and easier to manage. Major clustering improvements in Windows Server 2008 R2 include Live Migration support through Cluster Shared Volumes, enhanced support for IPsec security, and expanded cluster storage.
Progent offers a full range of Windows Server 2008 Server consulting services and Windows Server 2008 R2 expertise and can assist businesses of any size to maintain and troubleshoot failover clusters powered by Windows Server 2008. If you are considering an upgrade to Windows Server 2016, Progent can provide Windows Server 2016 failover clustering consulting to maximize the availability and performance of your system.
New and Improved Features of Windows Server 2008 Failover Clustering
The failover clustering capabilities incorporated into Microsoft Windows 2008 Server represents more than a decade of Microsoft's experience in developing clustering technology. The Enterprise and Datacenter Editions of Microsoft Windows Server 2008 offer a number of new clustering services and capabilities including:
More Convenient Management Interfaces
Windows Server 2008 includes Microsoft Management Console (MMC) 3.0, a new easy-to-use interface for controlling network resources. The new Failover Cluster Administration Console is task oriented rather than cluster resource oriented. To make a file share highly available, for example, the administrator no longer has to create a group, a disk resource, an IP address resource, Network Name, configure IsAlive/LookAlive, configure preferred services, and set dependencies. Instead, the wizard simply asks for the Network Name. You do not necessarily need to assign an IP address because Windows Server 2008 failover clustering now supports DHCP.
Windows Server 2008 also supports remote management via the Remote Server Administration Tools (RSAT). You can manage multiple clusters throughout the organization from a single MMC. Windows Server 2008 Failover Clusters are also fully scriptable with Windows Management Instrumentation (WMI).
Built-in Cluster Validate Tool
Windows Server 2008 clustering includes a cluster Validate Tool, an expanded and integrated version of the ClusPrep tool released for Windows Server 2003 server clustering. As a part of the cluster configuration process, Validate runs a set of tests to determine whether the selected servers, cluster networks, and storage meet the requirements for failover clustering. Validate performs an inventory that includes BIOS information, operating systems, adapters, drivers and software updates; verifies cluster topology for redundancy; checks IP configuration details; and makes sure that storage can correctly handle simulated cluster actions. The Validate Tool helps prevents configuration errors, which is one of the most common problems encountered in failover clusters.
Support for Windows Server 2008 Server Core
Windows Server 2008 offers a Server Core installation option that supports failover clustering and provides a bare-bones environment for running distinct server roles. By limiting the services that need to be maintained and updated, this minimalist installation reduces support and management expense and enhances security by shrinking the server's attack surface. Server Core supports a variety of important roles including DHCP server, file services, print services, DNS server, Active Directory Domain Services, streaming media services, and Windows Server 2008 virtualization.
Better Storage and Backup Support
Improvements in storage and backup offer increased stability and availability for failover clusters. Support for both Master Boot Record (MBR) and GUID Partition Table (GPT) disks allows the creation of disks greater than 2 terabytes. Built-in logic initiates self healing automatically as long as the system can find either the disk signature in the Master Boot Record or the SCSI inquiry page 0x83 data (VPD).
Support for Storage Area Networking (SAN) solutions is improved for storage hardware that supports SCSI-3 SPC3-compliant SCSI commands for persistent reservation/release. All multi-path solutions are Microsoft Multipath I/O (MPIO). The Device Specific Module (DSM) provided by the storage vendor is responsible for sending PR registration information down each path to the storage system. Closer integration with Volume Shadow Copy Service (VSS) makes the backup process easier. Failover clustering in Windows Server 2008 has its own VSS.
Greater Expandability
With Windows Server 2008, x64-based failover clusters support up to 16 nodes in a single cluster, as opposed to the maximum of 8 nodes in Windows Server 2003. Windows Server 2008 failover clusters also now support GPT disks, which use the GUID partition table (GPT) disk partitioning system. A GPT disk allows up to 128 primary partitions and a much larger volume size. In comparison, MBR disks can support up to four primary partitions and a volume size limit of up to 2 terabytes. For greater reliability, GPT disks offer replication and cyclical redundancy check (CRC) protection of the partition table. The increased number of nodes plus support for GPT disks dramatically extends the scalability of larger volumes in cluster environments.
A New Quorum Model
Windows Server 2008 introduces a new failover clustering quorum model that incorporates a combination of Microsoft's earlier shared disk and majority node set models. In Windows Server 2008 failover clustering there are now four ways to establish a quorum:
- No Majority - Disk Only (same as Windows Server 2003 shared disk quorum)
- Node Majority (same as the Windows Server 2003 majority node set)
- Node and Disk Majority
- Node and File Share Majority
An Improved Security Model
Windows Server 2008 failover clustering incorporates a new security model that enhances its security and dependability. Changes include:
- Elimination of the need for a domain user account for the Cluster Service Account (CSA)
- Better logging and event tracing
- Transition from unsecure datagram remote procedure call (RPC) communications to TCP-based RPC communications
- Default enabling Kerberos authentication on all cluster network name resources
- The ability to audit access to the cluster service via either the Failover Cluster Management snap-in or the cluster command-line interface
- Ability to secure Inter-Cluster communications.
New Networking Capabilities and More Flexible Dependencies
Windows Server 2008 failover clustering includes a new networking model. Major improvements include:
- Enhanced support for geographically distributed networks
- The ability to place cluster nodes on different networks
- The ability to use DHCP server to assign IP addresses to cluster interfaces
- Improvements in the cluster heartbeat mechanism
- Support for IPv6
Cluster IP address resources can now get their addressing from DHCP servers as well as from static entries. The cluster heartbeat mechanism has moved from a UDP broadcast health checking mechanism to a UDP unicast communication that it uses a Ping-like Request-Reply process. This allows better security and more reliable packet sequence numbering. Windows Server 2008 supports IPv6 IP Address resources and IPv4 IP Address resources either alone or in combination in a cluster. Clustering also supports 6-4 and Intra-site Automatic Tunneling Addressing Protocol (ISATAP).
Enhancements to Failover Clustering In Windows Server 2008 R2
Major enhancements to Failover Clustering available with Windows Server 2008 R2 include:
- Clustered Shared Volumes (CSV) with dynamic I/O redirection
- Geographically dispersed clustering for immunity from natural disasters
- Easier setup and migration through the new Best Practices Analyzer
- Redundant Quorum Resource to eliminate single-point failure for the cluster quorum
- Improved security through support for IPsec security between client and cluster nodes
- Supports for GPT disks that exceed 2 terabytes in capacity
