NIC
|
Monitors a configured NIC. If a network link fails or if a problem arises with the NIC, the resource is marked FAULTED. You can use the NIC agent to make a single IP address on a single adapter highly available and monitor it. No child dependencies exist for this resource.
For the NIC agent, VCS supports Linux bonded interface.
|
IP
|
Manages the process of configuring a virtual IP address and its
subnet mask on an interface. You can
use the IP agent to monitor a single IP address on a single adapter.
The interface must be enabled with a physical (or administrative) base IP
address before you can assign it a virtual IP address.
For the IP agent, VCS supports Linux bonded interface.
|
MultiNICA
|
Represents a set of network interfaces and provides failover capabilities between them. You can use the MultiNICA agent to make IP addresses on multiple adapter systems highly available and to monitor them. If a MultiNICA resource changes its active device, the MultiNICA agent handles the shifting of IP addresses.
For the MultiNICA agent, VCS supports Linux bonded interface.
|
IPMultiNIC
|
Manages a virtual IP address that is configured as an alias on one interface of a MultiNICA resource. If the interface faults, the IPMultiNIC agent works with the MultiNICA resource to fail over to a backup NIC. The IPMultiNIC agent depends upon the MultiNICA agent to select the most preferred NIC on the system.
For the IPMultiNIC agent, VCS supports Linux bonded interface.
|
DNS
|
Updates and monitors the mapping of host names to IP addresses and canonical names (CNAME). The DNS agent performs these tasks for a DNS zone when it fails over nodes across subnets (a wide-area failover). Use the DNS agent when the failover source and target nodes are on different subnets. The DNS agent updates the name server and allows clients to connect to the failed over instance of the application service.
|
AWSIP
|
Manages the networking resources in an Amazon Web Services
(AWS) cloud environment. The agent uses AWS CLIs to create IP resources in an AWS cloud environment. The agent does the following:
Assigns and configures private IP address
Associates public IP address and configures private IP along with elastic IP
Manages route table for overlay IP for failing over across subnets
|
Route53
|
Amazon Route 53 is a highly available and scalable cloud Domain Name System
(DNS) web service. The Route53 agent updates and monitors the host name to IP
address mapping. The agent does the mapping for the AWS Route 53 domain when
failing over nodes across subnets. Use the Route53 agent if the Resource Records need to be dynamically added and
deleted from the Route 53 domain during failover. The agent updates the name
server with the new resource record mappings while failing over and allows the
clients to connect to the failed over instance of the application.
