Service Availability Forum (SA Forum ) Cluster Membership Service (CLM) API
|
Triggers fast failover, isolates faulty node and performs cluster membership
|
Standards based API functions, allows for heterogenous multivendor networks capability with ease of standardized management functions
|
|
Reliable NFS
|
Provides a reliable file system accessible through NFS, enabling failover of NFS data and services to backup in case of failure.
|
Limited loss of service or corruption of committed data in case of physical disk failure or NFS server failure.
|
|
Reliable Boot and DHCP Services
|
Enables node reboot regardless of potential hardware or software failures in the cluster
|
Reliable Support for diskless nodes (Solaris OS or other)
|
|
Reliable IP Transport
|
Helps ensure that a single network failure does not result in data loss and provides zero time failover IP
|
Continuous cluster communication: No latency when errors occur on a link or during failure of a single link
|
|
Rolling Upgrade
|
Allows for Netra HA software version upgrade on a node by node basis without taking the node out of service
|
Improves serviceability and continuous availability of application while nodes within cluster are undergoing software upgrade
|
|
External Address Management capability
|
Maintain a logical to physical IP address mapping for the
master and vise-master.
|
Application can relate to the NHAS service provider (machine)independent of where it currently is running.
|
|
High levels of horizontal scalability supported with dynamic clusters of loosely coupled nodes
|
Enables the dynamic addition of new nodes and applications
|
Helps customers meet growing network demands by adding new nodes and applications for capacity on demand.
|
|
Fault management capabilities
|
Detects node failure, tracks cluster registration, and informs applications of cluster changes
|
Fast detection of failure for fast reaction.
|
|
Based on open industry standards and stable Solaris Operating System compatible APIs
|
Be fully compatible with the Solaris Operating System (OS)
|
Easy integration into existing infrastructures and interoperability in multi-vendor environments
|
|
External connectivity to the Netra High Availability (HA) Suite cluster
|
Provides monitoring and software management
|
Cluster-wide management statistics are accessible on the primary node, and are designed to failover to the secondary if the primary fails.
|
|
Reliable connectivity to SNMP/JMX management agent
|
Provides failover access to monitoring information and statistics
|
Cluster management information are always available.
