Test HA Setup for SIP & RM with VM

Voice & Telephony
1

Hi,

I want to setup & test the configuration for SIP Server HA & RM HA using NLB method.

Is it feasible to do the HA configuration & test it with the following components in a single physical host on VMWare Server running multiple Windows 2003 VM images as listed below:-

  1. 1 Physical Host Server with enough RAM & CPU, say 16 GB RAM and 16 core CPU and 4 NIC’s

  2. Run 6 VM on this host1 each with 2GB RAM and 2 core processors.

  3. Use 2 VM image for SIP Server HA

NIC1 192.168.1.2
NIC2 192.168.1.3
NIC3 192.168.1.4
NIC4 192.168.1.5
VIP 192.168.1.30

  1. Use 2 VM image for RM HA
    NIC1 192.168.1.6
    NIC2 192.168.1.7
    NIC3 192.168.1.8
    NIC4 192.168.1.9
    VIP 192.168.1.40

  2. Use 1 VM image for GVP components (MCP, CCP,RS,SSG)
    NIC1 192.168.1.10
    NIC2 192.168.1.11

  3. Use 1 VM image for Oracle DB
    NIC1 192.168.1.12
    NIC2 192.168.1.13

The objective is to be able to test the configuration steps in a test environment like this and be sure about all the steps before moving to prodn setup.

Thanks.
M.

And..what is the question or problem?

3

Will this test setup fine and a workable confign with all the elements that i described?
Note:- I dont have access to the local switch, hence I presume no switch confign (ARP etc) is required on my local switches.

4

Yes, it will.
I have tested similiar env (only on Linux (I hate WindowsNLB)) with worst HW and all what I need was OK.

5

One thing - NLB is no longer recommended for windows with release of 8.1.1 SIPS - I would recommend to use ip takeover. In general I don’t think it is need it to have more than 2 network cards in each virtual server

6

Or try to use active-active mode on RM with SIP server as a load-balancer. I know, that the documentation is not clear about it, but I have tested it and it works fine. I think better than IP takeover,at least on RM.

7

Yes it is good solution but than You have to use latest version of 8.1.1 because first release had some problems with active/active RM. And to fully remove NLB we can go into proxy for SIPS HA

8

I am using GVP 8.1.6 and I would definitely want to use the same approach for both SIP and RM.
Hence I would like to use NLB with both SIP & RM HA. My preferred HA method is Active - Standby.
With IP Address takeover, the documentation comments does not favour it, even though it is simpler.

9

I do not recommend to use IP takeover mechanism for RM, my experience is that it did not work properly.

10

can you tell me what feature license is required in order to test SIP HA & RM HA?
i.e. i need to verify what feature license should be in my license file in order to test the HA features of SIP & RM.

Is it only HA-VOICE in addition to the SIP & GVP licenses?

11

To tell the truth, I have to say “I do not know” … licensing is not my field of interest. But I hope and believe that others from this forum know this information. I think that you are right with “only” HA voice license.

12

in case of sip, ha-voice isn’t required. for full Hotstandby HA you’ll need:
cim, cim-ha
sip, sip-ha
gvp and gvp-ha

Smile, thanks for additional info about licensing (is not my cup of tea) :slight_smile:

Smile,
my setup is warm standby only for both sip & rm.
i have HA-Voice, HA-CIM and this feature “FEATURE ha_redundancy”.
i hope this should allow both RM & SIP server to support HA in warm standby option.
