Networking, Hardware Issues, SQL Server and Terminal Services Session VII

What is a computer network ?

Computer Network: A group of two or more computers linked together electronically.

Common Types of Networks: Fast Ethernet Gigabit Ethernet Wireless – B Wireless – G

100mbit Data Packet Transfer Requires Fast Ethernet Network Adapters and Switches Most common type of network Fast Ethernet :

Gigabit Ethernet : 1000mbit data packet transfer Requires Gigabit Network Adapters and Switches Gaining popularity with affordability

Wireless: B Capable of 11mbit Data Transfer G capable of 54mbit or 108mbit No Wires!! Ad-Hoc / Access Point Network Bridge to Wired Network Data Encryption Recommended

Types of Networking: Peer to Peer –Workstations linked to other workstations –“Share” resources to create network devices –Basic security of password protection Client / Server –Workstations linked to dedicated servers –More advanced networking capabilities –Enhanced security of Active Directory –More versatile and capable of higher production

Networking Hardware: Switches / Hubs / Routers Desktop / Server Network Adapters Network Operating System Software Mass Storage Media Back Up System Fault Tolerant Devices Security Components

Hardware Issues: Redundancy –Server hard drives (RAID) –Scanners –Any other mission critical pieces? How long can you afford to be down?

Most Important Considerations: Reliability Fault Tolerance Security Speed / Performance Usability Scalable Adaptability

Recommendations: Implement and upgrade to the latest hardware devices Implement and upgrade to the latest software versions Maintain comprehensive documentation Implement and test effective backup solution Utilize qualified support individuals Evaluate needs annually

SQL Server Latest Service Packs –SQL 2000 SP3a –SQL 7 SP4 Microsoft Free Tools –Microsoft Baseline Security Analyzer (MBSA) –Best Practices Analyzer Tool for MS SQL Server SQL Server 2005 coming next summer

Terminal Services Ports needed for access tcp/3389 Licensing Issues –Windows 2003 Server –Small Business Server –Terminal Server Other issues
