Call manager high availability

What is the difference between the callmanager high availability software and server hardware? Can you install the software on any server? Can you buy the high availability hardware without the software?

Please enlighten me.

Thanks,

Ohamien

Re: Call manager high availability

High availability can be built into Callmanager design using

** multiple servers in a cluster

** using servers that have redundant RAID controllers/hard drivers

** using servers with redundant power supplies

** high availability built into the network (Core, distribution, access)

Re: Call manager high availability

That's what I thought but the original poster made it sound as if there were specific high availability packages available, including software. I wanted to make sure that something new hadn't come out in that regard without me knowing about it. :-)

One of the issues I have with Cisco IPT is the lack of true high availability, and by that I mean redundant Publishers.

NO, you cannot install the CCM software in any machine, MUST be Cisco Supported platform (Technically you can do it but you are breaking the license agreement)

Re: Call manager high availability

That is what I know high availability to be, but I was told that the H1 in CM4.1-K9-7825-H1 also stood for high availability. I was just making sure that there is no difference between CM4.1-K9-7825= and CM4.1-K9-7825-H1

Re: Call manager high availability

H stands for HP.

I stands for IBM

Cisco OEM's HP and IBM servers

MCS-7825-H1-IPC1 - HP version

MCS-7825-I1-IPC1 - IBM version.

Depending upon the type of server you buy, you need to get Callmanager software thats bundled specifically for HP or IBM. The CM software is the same, but Hardware detection CDs are different for either servers.

CM4.1-K9-7825-H1 is for HP server and CM4.1-K9-7825-I1 is for IBM Server.

Those alphabets has nothing to do with HA.

Also, difference between CM4.1-K9-7825 and CM4.1-K9-7825-H1 is that hardware detction cd's are different in either bundles. These two bundles are for two different HP servers.
