| Table 4.3 outlines hardware requirements for SQL Server 2005 installations. The following is the terminology used in relation to the 64-bit platform: -
IA64 refers to Itanium-compatible hardware architecture. This architecture can run IA64 software and 32-bit software using the Windows-On-Windows (WOW64) software emulator. The Itanium CPU cannot natively run 32-bit x86-compatible instructions and uses instruction emulation as a part of WOW64 processing. -
x64 refers to Extended Memory Technology support compatible architecture and includes systems, based on Opteron, Athlon 64, Intel Xeon EM64T, and Intel Pentium EM64T. x64 architecture can run classic 32-bit x86 compatible instructions natively on the CPU. One of the advantages of this architecture is an ability to support both 32- and 64-bit code. To ease an adoption of the 64-bit platform and optimize a hardware purchase, some companies might first deploy a 32-bit operating system and software on x64 hardware and then upgrade to 64-bit software on the same hardware. Table 4.3. Minimum Hardware Requirements | Hardware | Minimum Requirements 32-Bit | Minimum Requirements 64-Bit | | CPU | Intel or compatible Pentium III or higher Minimum: 600MHz Recommended: 1GHz or higher | IA64 recommended: 1GHz X64 minimum: 1GHz | | Memory (RAM) | 512MB minimum, 1GB or more recommended, 4GB maximum per a Report Server instance Report Server will utilize a maximum of 3GB (with /3GB switch in boot.ini). | 512MB minimum, 1GB or more recommended | | Hard disk space | A combination of hard drive requirements for the installed component: Report Server, Report Manager, and so on. A set of SSRS- related components is shown in Table 4.1. Full SQL Server Install is approximately 1.5 GB. | Approximately 2-3 times of the size of 32-bit components | | Monitor (Visual tools will function at a lower resolution, such as 640x480) | VGA or higher resolution 1024x768 or higher resolution recommended for SQL Server graphical tools. | VGA or higher resolution 1024x768 or higher resolution recommended for SQL Server graphical tools | | Pointing device | Microsoft Mouse or compatible pointing device. | Microsoft Mouse or compatible pointing device | | CD-ROM drive | Required for CD installation. | Required for CD installation | Note System Configuration Check blocks setup from running if the CPU type (Pentium III or higher) requirement is not met. Setup issues a warning, but allows you to proceed, if the CPU speed or minimum memory requirement is not met . |
