[!INCLUDEappliesto-ss-xxxx-xxxx-xxx-md] This topic describes the options of the Specify Availability Group Name page. This topic is used by both the [!INCLUDEssAoNewAgWiz] and [!INCLUDEssAoAddDbWiz] of [!INCLUDEssCurrent].
Availability group name
Specify the name of the availability group. For a new availability group, specify a valid [!INCLUDEssNoVersion] identifier that is unique across all availability groups in the Windows Server failover cluster (WSFC). The maximum length for an availability group name is 128 characters.
Cluster type Next, specify the cluster type. The possible cluster types depend on the [!INCLUDEssNoVersion] version and operating system. Choose one from the following list:
-
Windows Server Failover Clustering
Use when the availability group is hosted on instances of [!INCLUDEssNoVersion] that belong to a Windows Server failover cluster for high availability and disaster recovery. Applies to all supported versions of [!INCLUDEssNoVersion].
-
EXTERNAL
Use when the availability group is hosted on an instance of [!INCLUDEssNoVersion] that is managed by an external cluster technology for high availability and disaster recovery, for example Pacemaker on Linux. Applies to [!INCLUDEsssqlv14] and later.
-
NONE
Use when the availability group is hosted on an instance of [!INCLUDEssNoVersion] that is not managed by a cluster technology for read scale and load balancing. Applies to [!INCLUDEsssqlv14] and later.
Database level health detection Check this box to enable database level health detection (DB_FAILOVER) option for the availability group. The database health detection notices when a database is no longer in the online status, when something goes wrong and will trigger the automatic failover of the availability group. See SQL Server Always On Database Health Detection Failover Option.
