servers 2 1 2004 Pearson Education Inc Exam 70 297 Designing a Microsoft Windows Server 2003 Active Directory and Network Infrastructure Lesson 2 Examining the Current Services Infrastructure Skill 1 Examining the Current File Print and Application Servers 2 File servers Often the most overlooked type of server Disk subsystem performance and network connectivity are of primary importance 2 2 2004 Pearson Education Inc Exam 70 297 Designing a Microsoft Windows Server 2003 Active Directory and Network Infrastructure Lesson 2 Examining the Current Services Infrastructure Skill 1 Examining the Current File Print and Application Servers 3 File server disk subsystems Typically use some form of PCI bus Server motherboard determines which PCI specification the system is capable of using Performance of disk subsystem Cannot exceed bus performance Because all subsystems share the same bus the maximum achievable transfer rate is usually slightly less than half of the maximum theoretical rate for the bus 2 3 2004 Pearson Education Inc Exam 70 297 Designing a Microsoft Windows Server 2003 Active Directory and Network Infrastructure Lesson 2 Examining the Current Services Infrastructure Skill 1 Examining the Current File Print and Application Servers 4 File server disk subsystems For redundancy and fault tolerance must use some form of RAID RAID 5 with a hardware controller RAID 0 1 RAID 10 RAID 0 provides exceptional speed but no redundancy 2 4 2004 Pearson Education Inc Exam 70 297 Designing a Microsoft Windows Server 2003 Active Directory and Network Infrastructure Lesson 2 Examining the Current Services Infrastructure Skill 1 Examining the Current File Print and Application Servers 8 Print servers Disk space and performance are of primary concern Network adapter also an area of major concern to maximize performance RAM and processor needs while not unimportant are not as a major concern in comparison to storage and network connectivity needs Additional considerations include all integration and software configuration concerns 2 5 2004 Pearson Education Inc Exam 70 297 Designing a Microsoft Windows Server 2003 Active Directory and Network Infrastructure Lesson 2 Examining the Current Services Infrastructure Skill 1 Examining the Current File Print and Application Servers 9 Application servers Needs vary greatly depending on specific application Best to use a pilot to determine needs of server if at all possible If a pilot is not feasible do extensive research on the needs and limitations of the server check for vendor white papers 2 6 2004 Pearson

Infrastructure Skill 2 Examining the Current DNS Infrastructure 5 Versions of DNS server services in place Unix and Linux DNS servers typically run a version of Berkeley Internet Name Domain BIND BIND version 4 9 7 is minimum version capable of supporting SRV records so any earlier version cannot be used to host DNS domains for Active Directory BIND version 8 1 2 and higher versions are recommended as they include support for DNS dynamic updates BIND version 8 1 1 also supports DNS dynamic updates but is not recommended due to flaws BIND does not support Active Directory
