If things like dual NIC capability, dual PSUs, hot-swap media (line) cards are things that are important to you then CM is the beast.
Indeed, hold your horses!!!
I saw this on a doc on the avaya partner portal so i can share without violation the NDA
Avaya Proprietary and Confidential Revision 2, May 22, 2012 Page 15 of 59
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
Avaya Proprietary and Confidential Revision 2, May 22, 2012 Page 16 of 59
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
This is from the 8.1 product upate doc!!!
I'm not insane, my mother had me tested!
