The Cluster service controls server cluster operations and manages the cluster database. A cluster is a collection of independent computers that act as a single computer. Managers, programmers, and users see the cluster as a single system. The software distributes data among the nodes of the cluster. If a node fails, other nodes provide the services and data that were formerly provided by the missing node. When a node is added or repaired, the cluster software migrates some data to that node.
Some Windows Server 2008 R2 Failover Cluster Notes
MySQL with Windows Failover Clustering requires at least 2 servers within the cluster together with some shared storage (for example FCAL SAN or iSCSI disks). For redundancy, 2 LANs should be used for the cluster to avoid a single point of failure and typically one would be reserved for the heartbeats between the cluster nodes.
Since Microsoft Windows 2012, Microsoft have reconfigured the way in which you can manage High Availability with print services. They introduced the ability to use Hyper-V and failover clustering to make your print server a highly available virtual machine. This solution provides full server failover options and can be implemented with the PaperCut NG/MF Application Server, Secondary Server, and/or Site Server.
Windows Server 2008 includes a variation of installation called Server Core. Server Core is a significantly scaled-back installation where no Windows Explorer shell is installed. It also lacks Internet Explorer, and many other non-essential features. All configuration and maintenance is done entirely through command-line interface windows, or by connecting to the machine remotely using Microsoft Management Console (MMC). Notepad and some Control Panel applets, such as Regional Settings, are available.
A Server Core installation can be configured for several basic roles, including the domain controller (Active Directory Domain Services), Active Directory Lightweight Directory Services (formerly known as Active Directory Application Mode[13]), DNS Server, DHCP server, file server, print server, Windows Media Server, Internet Information Services 7 web server and Hyper-V virtual server roles. Server Core can also be used to create a cluster with high availability using failover clustering or network load balancing.
In Windows Server 2008, the way clusters are qualified changed significantly with the introduction of the cluster validation wizard.[19] The cluster validation wizard is a feature that is integrated into failover clustering in Windows Server 2008. With the cluster validation wizard, an administrator can run a set of focused tests on a collection of servers that are intended to use as nodes in a cluster. This cluster validation process tests the underlying hardware and software directly, and individually, to obtain an accurate assessment of how well failover clustering can be supported on a given configuration.
SAS Enterprise Guide and the SAS Add-In for Microsoft Office do support fail-over for initial connections. However, SAS Enterprise Guide and the SAS Add-In for Microsoft Office do NOT currently support complete active fail-over. Meaning, some level of SAS metadata server session failover does exist.
People get creative in how to achieve things due to inconsistencies, differences in functionality between Hyper-V Manger and SCVMM 2008R2 (in the latter especially the lack of complete control over naming, files & folders, export/migration behavior) as well as the needs of the failover cluster can lead to some confusing scenarios.
(Windows OS specific question) built_in SAS HDDs in RAID1 + 5 isn't possible to add to the pool in Windows Server failover cluster (members are empty) but is possible to create a pool for each of noded in Server view, e.g. then to create iSCSI. Why those two options seems like as not doing the same things; specific server can see available HDD for pool, from Windows failover is/are member empty. 2ff7e9595c
