Provisioning levels
- nominal: what's needed, additional as needed
- minimum: what's needed, no additional resources
- dedicated: take everything, one module only
Elements
- node = ip addres of physical device
- pool member = node + service port
- pool = group of related pool members for load balancing
- virtual server = web listerner (often associated with a pool)
Processing order
- Existing connection in conn table
- Packet filter rule
- Virtual Server
- SNAT
- NAT
- SelfIP (check lockdown)
- Drop
Types of Virtual Server
- Standard Virtual Server
- Forwarding IP
- Forwarding L2
- Performance HTTP
- Performance L4
- DHCP Relay
Virtual Address Status
- green circle - enabled
- yellow triangle - unavailable (conn limit)
- red diamond - offline due associated object
- black circle - disabled
- blue square - unknown (no monitors associated)
Pool Status
- green circle - any pool member available
- yellow triangle - no pool member available (conn limit)
- red diamond - offline due monitor
- black circle - disabled
- blue square - unknown (no monitors associated or unreachable)
Pool Member Status
- green circle - enabled
- yellow triangle - unavailable (conn limit)
- red diamond - unavailable (pool/node down)
- black circle - disabled (monitor detects up)
- black diamond - disabled
- blue square - unknown (no monitors associated or unreachable)
Pool member disabled still process persistent/active connections (but not when Down)
Pool member Forced Offline no new connections (just active)
Virtual Server disabled still process persistent/active connections
Opening support tickets
- Severity 1 - 1 hour - preventing execution of critical business activities
- Severity 2 - 1 hour - preventing / impairing high level business activities
- Severity 3 - 4 hour - conditions degradating service
- Severity 4 - 24 hour - requests for new functionalities
