Netra High Availability Suite
Datasheet
|
Today's competitive telecom industry is facing pressure to reduce CAPEX and OPEX while at the same time accelerate time to market. Network equipment providers (NEPs) and original equipment manufacturers (OEMs) must provide highly available and scalable systems to carriers so that services are available to end users all the time with little or no downtime.
Key Highlights
Sun's Netra High Availability (HA) SuiteSun's Netra High Availability (HA) Suite Foundation Services provide a reliable and scalable platform on which developers and system integrators can rapidly develop and deploy highly available applications. In addition, Netra HA Suite Foundation Services offer customers enhanced reliability for system services, increasing overall availability. Using Netra HA Suite Foundation Services 2.1 7/05, customers can build cost-effective, carrier-grade HA solutions for network infrastructures, blade computing, and embedded environments.Netra HA Suite benefitsNetra HA Suite Foundation Services help customers accelerate the deployment of highly available applications while lowering costs.Reduced development costs Leveraging Netra HA Suite Foundation Services, customers can create HA services on their highly available integrated environment with minimal development costs. Eliminating the burden of recreating HA middleware, customers can focus their resources on competitive services. Faster integration With Sun's Netra servers and board-level products, customers benefit from a complete preintegrated hardware and software platform, reducing final integration time. Quicker deployment Based on open standards, Netra HA Suite Foundation Services can easily be deployed into existing or new HA environments with minimal development effort.  Continuous availability of core servicesRedundancy for preventing failuresRedundant software and hardware components and communication links ensure that the Netra HA Suite Foundation Services cluster provides a reliable core platform and does not present any single point of failure. Reliable NFS service Netra HA Suite Foundation Services provide a reliable file system accessible through NFS. This reliable NFS service leverages the redundancy of the hardware platform, enabling failover of NFS data and services to the secondary node if the primary fails. Features include:
Enhanced reliability for standard boot and DHCP services helps ensure that diskless nodes can boot correctly despite hardware and software failures. Features include:
Cluster communication is duplicated over two high speed Ethernet links. In the event of an error on a single link, vital information continues to its destination on the second link without retransmission, eliminating latency in communication. Features include:
Netra HA Suite Foundation Services include reliable, Java Management Extension (JMX) API-compliant node management agents to monitor core services. Cluster-wide management statistics are accessible on the primary node, and are designed to failover to the secondary if the primary fails. Features include:
Reduction of planned outagesNetra HA Suite Foundation Services make it possible to replace nodes on a running cluster. Customers do not need to plan system outages for hardware replacements and upgrades.Mapping services to nodes With Netra HA Suite Foundation Services, IP addresses and software can be assigned to specific nodes for DHCP and boot services. If a node fails, it can be replaced and the new node will run the same software and service. Fault management Core fault management is provided by the cluster membership management service, which detects node failure, tracks cluster registration, and informs applications of cluster changes. Netra HA Suite Foundation Services also include a process monitor daemon and watchdog timer that contribute to fault management.
Enables Foundation Services version upgrade on a cluster without service interruptions. External management capabilities External access to the Netra HA Suite Foundation Services cluster enables customers to easily access cluster information and conduct management and administration tasks from outside the cluster. Easy to develop and deployOpen standardsTo ensure ease of integration into existing infrastructures and interoperability in multi-vendor environments, Netra HA Suite Foundation Services are based on open standards, such as IP, DHCP, NFS, SNMP, SA Forum CLM, and the JMX open specifications. Full Solaris OS compatibility Netra HA Suite Foundation Services are fully compatible with the Solaris Operating System (OS), leveraging all the benefits of this robust OS and utilizing the same APIs, protocols, and standards for easy development and deployment. It extends the Solaris OS with carrier-grade extensions. Similar extensions are also planned for carrier-grade (CG) Linux. Embedded solution Netra HA Suite Foundation Services are designed to be embedded inside the customer solution, eliminating the burden to create a specific HA platform. Higher availability for existing software Netra HA Suite Foundation Services can be integrated with certain non-HA-aware software, allowing the cluster to benefit from higher availability levels without additional development. Horizontal scalability Netra HA Suite Foundation Services are designed to scale horizontally, helping customers meet growing network demands by adding new nodes and applications for capacity on demand. Software installation and configuration Automated and manual installation enables a high level of flexibility in the software configuration. Features include:
Hardware platformsTo meet different customer needs, Netra HA Suite Foundation Services 2.1 is compatible with a range of Sun Netra hardware platforms.
