Chapter 3 - System Components <br />Approved Virtualization Product <br />TriTech has approved VMware's vSphere ESXi as a supported hypervisor for Production use with the Inform <br />CAD suite. Support for the vSphere Hypervisor will be through VMware. Customers should ensure that their <br />personnel have been trained in the installation and management of this software and that software support and <br />services has been purchased for this system. <br />httD://www.vmware.com/stinr)ort/ <br />The following servers are approved for virtualization <br />/ Inform CAD <br />/ Inform Archive & Reporting server(s) <br />/ Citrix server running Inform CAD <br />1 Business/Interface servers such as: <br />- ANI/ALI <br />- Paging <br />- Inform CAD Web Server <br />- Inform CAD Browser Server <br />- Inform CAD Mobile Server <br />During testing of a virtual Citrix server under simulated load, TriTech determined that a single Citrix user uses <br />approximately the resources of a physical or hyper -threaded processor on the physical host. For a small <br />deployment of Citrix users, a virtual Citrix server may be sufficient but for a large deployment of Citrix users, <br />physical hardware is recommended. <br />TriTech tested and approved Areserve HA as the Disaster Recovery software solution. Some TriTeeb clients <br />have opted to use VMware SRM in conjunction with SAN to SAN replication as their DR solution. TriTech will <br />work with our clients on a consulting basis to assist with the failover process and testing. Maintaining the <br />failover process and solution is the responsibility of the client. <br />The free version of vSphere ESXi is approved for Training/Testing systems. However please note there is no <br />support from VMWare available on the free version. <br />Customers electing to deploy vSphere ESXi in their Production environment should carefully assess server <br />capacity and should perform a limited rollout of VMware Server with a preplanned roll -back strategy. It should <br />be understood by the customer that when planning a virtual solution, performance for a VM is measured in MHz <br />and MB of RAM. Although a single virtual 2.26GHz CPU may be allocated to the VM, the server will only <br />consume the amount of vCPU resources needed to perform its task However, great care must be taken to not <br />over -subscribe host server resources to VMs as performance issues will likely be incurred. TriTech also <br />recommends the use of Shared Storage. <br />Customers should also be aware of software licensing models. Understand how VMware licenses their product as <br />well as the benefits of using Microsoft Data Center licensing 2012 VS Windows Server 2012 Standard licensing. <br />With proper planning and server capacity, vSphere ESXi can be used effectively in a Production environment. <br />TriTech has not tested Microsoft's Hyper-V Hypervisor solution. Customers who are comfortable with <br />Microsoft's Hyper-V solution can deploy it at their own risk. <br />The contents of this material are confidential and proprietary to TriTech Software Systems, Inc. and may not be reproduced, <br />published or disclosed to others without the prior written consent of TriTech Software Systems, Inc. <br />©2015 TriTech Software Systems <br />
