  27. 27. HW Platform alternatives • Platform independent architecture • The pre-tested platforms are based on current Charging Gateway (HP Itanium rx series) platforms • High Availability for different needs – Either high volume mediation (HA based on clustered architecture) – Or charging gateway function (HA based on GTP’ protocol, N+1) – Redundant network connections • Scalable and distributed architecture – The HW can be placed in separate sites, however a cluster needs to be located in the same site – It is possible to extend a basic configuration by adding new machines or components 29 © Nokia Siemens Networks charge@once mediate marketing set / MSa / 19.09.2007
  28. 28. charge@once mediate HP rx server models • There are 3 possible HP rx HW models used in charge@once mediate : HP rx2660 – For new deliveries – With High-Availability or Stand-Alone resilience solutions – With internal or external disks for data storage HP rx2620 – For migration cases only (from CG4.x) – Requires some component extensions HP rx6600 – For high capacity mediation – Availability earliest in rel2.2 30 © Nokia Siemens Networks charge@once mediate marketing set / MSa / 19.09.2007
  29. 29. charge@once mediate Storage Options • In charge@once mediate there can be two possibilities for data storage*: – Using internal disks – Using an external disk storage system • Internal storage: – Capacity per server: 273GB (for both input & output data) • External storage: – EMC CX3-20 capacity: From 0.9TB up to 3.2TB (6 different options) *Note: In the clustered solution, external storage is mandatory 31 © Nokia Siemens Networks charge@once mediate marketing set / MSa / 19.09.2007
  30. 30. High-Availability • Clustered High Availability option for mediation cases • In a high-available (HA) solution there is no single point of failure in the HW configuration. • The collection and processing of UDRs is done without any downtime, even if there is a malfunction in one of the servers. • The HA HW is clustered and the solutions are built with an EMC CLARiiON external disk storage system and Veritas cluster server SW solution. • All the critical HW components are redundant. • Upto 8 servers within one cluster 32 © Nokia Siemens Networks charge@once mediate marketing set / MSa / 19.09.2007 Veritas controls the processing, making sure there is no downtime. When it detects a server failure, it brings the processing up on a different node in the cluster. It virtualizes IP addresses and system names, so that the sending network elements continue to access the servers and are unaware of which one they use.
  31. 31. GTP’ based n+1 redundancy • N+1 redundancy for CGF/packet core cases • The GTP’ protocol takes care of the redirection of the CDR traffic to another server, in case of a communication failure • To ensure that no CDRs are lost in communication failure situations, a minimum of 2 servers are needed (1 active + 1 backup) • The performance of the ’backup’ server has to be as high as the highest active server Note1: it is not recommended to have more than 4 active servers with only 1 backup. N active server 1 server waiting for Redirection 33 © Nokia Siemens Networks charge@once mediate marketing set / MSa / 19.09.2007
