ASU-II/ASU-III Servers

The ASU-II/ASU-III is a card designed to be used in the MX-ONE chassis where the total number of extensions does not exceed 10,000 extensions (for ASU-III) or 7,500 extensions (for ASU-II).

The ASU-II/ASU-III can be used in Multi-Service Nodes systems, however the total number of users in the system shall not exceed 25,000 extensions.

A large system using ASU-II/ASU-III shall not have more than 20 Service Nodes without Cassandra DB or 10 Service Nodes with Cassandra DB in a single logical system. However, there is no limitation when the ASU- II/ASU-III board is used in a standalone Service Node using SIP tie-lines between Service Nodes.

It is strongly recommended to always include the additional hard disk and run SW RAID 1 when installing MX- ONE servers.
