6.7 IP Office Resiliency
IP Office resiliency can be divided into three distinct categories. The primary server and secondary server can each support up-to 1000 users in resilient mode
Note: The Primary and Secondary servers can c-located or can be on separate locations to support Geo-Redundancy.
1. Hardware Resiliency
a. RAID support
b. Dual PSU on Avaya sourced HP DL360 G7
2. Users and Application Resiliency
a. VMPro server – Primary + Backup in 1+1 redundant active/passive configuration. Manual or auto failback control (auto is new for R8.1)
b. IP Phones – 1:1 resilience to backup IP Office. Manual failback control (Phone reset). Avaya H.323 phones only. Note Expansion systems (gateways) cannot act as backup nodes for the Linux Servers.
c. Hunt groups - 1:1 resilience to backup Server. Auto failback control (device rediscovery – idle group).
d. Inter IP Office device links – Multi-Site Network (SCN) backup. Double star. 1:1 resilience. Auto failback control (device rediscovery)
e. Inter IP Office device links – PSTN backup. M:N resilience via Alternate Route Selection (ARS). Auto failback control (link availability)
IP Office Release 8.1 Regional Applicability: All

f. Trunks – M:N resilience via ARS. Auto failback control (trunk availability)
g. Incoming Call Routes – Incoming Call Routes are common to all devices hence persist on user failover.
3. Trunk Resiliency
a. PSTN Back-up
