- In this sample, Renovations, Inc. maintains a regional data center in North America and in Europe. EMEA and AP users (38% of the total population) will use the EMEA datacenter.
- Renovations, Inc. leases 155Mb circuits for their WAN. This bandwidth is not enough to support the peak A/V from a single data center, and so distinct Media Managers will be maintained in each data center.
- Renovations, Inc. is going to leverage the proxy server for their customer portal; there is no high availability requirement for this component.
- Renovations, Inc. has asked for a highly available infrastructure supporting peak load plus tolerance for the failure of any single component in the system (with the exception of the Sametime Proxy Server)
The following are the server requirements for peak rates and high availability for Renovations, Inc.
