Subject: Re: Call Manager redundancy
Based on these comments, "The servers in Table 5 contain two network
interface cards (NIC), but Cisco CallManager supports only one NIC. When you
connect the server to the network, use the NIC connector listed in the table
because the other NIC is disabled during the installation.", from this page
(
http://www.cisco.com/en/US/products/sw/voicesw/ps556/prod_installation_guide
09186a00800f934d.html ) and a recent conference with Cisco engineers, using
both NICs (even with Compaq's Teaming Utility) is not supported by TAC. If
TAC logs into your box remotely, and finds a non-supported configuration,
they will require you to rebuild the CCM from scratch before providing any
assistance. We specifically asked them about redundant NICs, among other
changes, when we received that answer.
Just thought I should pass that on.

> Callmanager NIC redundancy is possible. Team utility of Compaq server
solves the problem. It creates a new card and you give IP address to that
card. In practice this new one is a virtual NIC that teams both physical
NICs. If you connect NICs to different switches you will have a redundant
Callmanager in case of a NIC failure or switch failure. I'm sure IBM servers
have this feature as well.
