10.2 Requirements for ShoreTel Enterprise Systems The ShoreTel Enterprise Edition system is scalable. For economy, ShoreTel Enterprise customers provide their own server hardware, allowing them to build the optimum phone system for their environment. To assist in creating the optimum system, ShoreTel has defined a tier system based on the number of users the system is to support and set minimum server requirements for each tier. The tiers defined by ShoreTel are: Small servers that support up to 500 users. Medium servers that support up to 2,500 users. Large servers that support up to 10,000 users. Very large servers that support up to 20,000 users. NOTE Customers upgrading from Small Business Edition (SBE) or Small Business Edition 100 (SBE 100) to Enterprise Edition can reuse their servers; however, this implementation scenario will invoke restrictions. See Section 10.3.2.3 on page 186 for more information. NOTE If a planned upgrade to the current release means that the current server cannot adequately support the new release of ShoreTel software, upgrade the server to a model with greater capacity before attempting to upgrade the server software. 10.2.1 Capacity and Hardware Requirements for Headquarters Servers Table 10-1 shows the system capacity for each tier of the headquarters (HQ) servers. Table 10-2 shows our recommendations for each tier. Use these tables to determine the needs for headquarters servers in your ShoreTel deployment. You can mix servers of different capacities. Be sure to choose the right servers for the telephony environment 180

NOTE 2 BHCC per server is based on the number of calls actually handled by the server during the busy hour, including workgroup calls in menus and queues, auto-attendant calls, and calls to the voicemail service. NOTE 3 By default, the ShoreTel report-generation tools that run on the server have a lower priority than other, more critical services. Low-demand reportgeneration should have little or no effect on a server with adequate performance specifications. If you generate a high volume of reports or experience any degradation of voicemail or other server prompts on an underpowered server, you must move up to the next tier level of servers. Note that report generation has an impact on system performance. ShoreTel recommends that customers run reports outside of business hours. If a customer needs reports during business hours, the supported calls per server for the medium and large server tiers is reduced as noted in the table. NOTE 4 For very large system deployments (10K to 20K users), the number of ShoreTel Communicator for Windows users is 500 per server. The number of ShoreTel Communicator for Web and Mobile users is 1000 per server. ShoreTel 13.3 181

Table 10-4 shows the minimum equipment capacities for each tier for DVSs. Use these tables to calculate the requirements for the DVSs in the ShoreTel deployment. You can mix servers of different capacities. Be sure to choose the right servers for the entire telephony environment.

Planning and Installation Guide 10.2.3 Operating System Requirements for All Servers This section lists the operating systems that ShoreTel 13.3 supports on the headquarters server and distributed voice servers. If you are upgrading a system to ShoreTel 13.3, refer to the Release Notes for special instructions that might apply. ShoreTel 13.3 supports the following operating systems in enterprise environments: Windows Server 2008 32-bit, SPx (Standard, Enterprise). NOTEPrioritization of traffic type is not supported on this platform. Windows Server 2008 R2, 64-bit, SPx, (Standard, Enterprise).
