Availability
Since the main function of MX-ONE is to offer telephony services, high availability and redundancy techniques are topics of the utmost importance. This section underlines some aspects related to availability and redundancy that need to be addressed in the planning phase.
All servers that are part of MX-ONE are based on industrial hardware platforms with extremely high availability standards. All servers are equipped with redundant fans units, and can be provided with additional hard disks in a RAID 1 configuration and additional Power Supply Units (PSU). It is strongly recommended to always include the additional hard disk (with RAID 1) and the additional PSU when choosing and configuring the MX-ONE servers.
SW RAID 1 is supported on ASU-II/ASU-III.
Particularly important when planning for availability is how to set up the power supply network. Each redundant network requires a separate power supply. For more information about power planning, see Power Planning.
