<div>We already have implemented DR and HA for CUCM 4.1 but not Unity 4.2. We are plan to upgrade CUCM to 7.x and Unity to Unity connection 7.x. I have suggested our consultant about DR and HA for Unity connection but they didn't recommend it saying that data replication between two unity connection servers may take more than 100mb.</div>
<div>We have 100MB connection between two locations for data and voice. <br>I would like to know more information about this like QoS and service policies. is there any link I can find information?</div><div><div></div>

<p class="MsoNormal">Regardless of what your consultants say, please bear in mind the Cisco recommendations are also guidelines for them to support you. If you run into HA issues with unity or IPCC and you go to get TAC support, there's a good chance you're not going to get full support out of Cisco if the overall system design doesn't meet requirements.</p>

<p class="MsoNormal"><span style="color: rgb(31, 73, 125); font-size: 11pt;">We are trying to move our secondary HA Cisco unified servers to the Sun Guard DR site.</span></p>
<p class="MsoNormal"><span style="color: rgb(31, 73, 125); font-size: 11pt;"> </span></p>
<p class="MsoNormal"><span style="color: rgb(31, 73, 125); font-size: 11pt;">We are going to install 2<sup>nd</sup> CUCM subscriber server at the DR site and move Secondary Unity and CRS server to the DR site. Leave Primary Unity and CRS server at the Corporate Data Center.</span></p>
<p class="MsoNormal"><span style="color: rgb(31, 73, 125); font-size: 11pt;"> </span></p>
<p class="MsoNormal"><span style="color: rgb(31, 73, 125); font-size: 11pt;">Question is this: We are going to have ATT 10Mbps MPLS circuit to the Sun Guard. Per Cisco document you at least have to have 100Mbps connection to the High Availability Servers but per our consultant people, 10Mbps is sufficient. I think this design will work fine but want to hear second opinion.</span></p>
<p class="MsoNormal"><span style="color: rgb(31, 73, 125); font-size: 11pt;"> </span></p>
<p class="MsoNormal"><span style="color: rgb(31, 73, 125); font-size: 11pt;">Has anyone done this before… Do you see any issue with this design?</span></p>
<p class="MsoNormal"><span style="color: rgb(31, 73, 125); font-size: 11pt;"> </span></p>
<p class="MsoNormal"><span style="color: rgb(31, 73, 125); font-size: 11pt;">Thanks for your help.</span></p>
