Presentation Transcript

  1. Chapters 1-3Concepts • NT Server Capabilities • Alternative Server Systems • Web • Windows Functions • Configurations • Protocols • Topology • Server Hardware

  2. NT Server Capabilities • Scalable • MS window interface • Different OS in workstations • E-mail, sharing resources, network communication • Microsoft backoffice products • Microsoft Mail Server, Internet Information Server, System Management Server, SQL Server • Secure • Reliable (fault tolerance)

  3. Alternative Server Systems • Novell - NetWare • DEC - PATHWORKS

  4. Web • Internet - Intranet (Internet Information Server) • Index Server for intranet access • HyperText Markup Language (HTML) - Microsoft’s FrontPage

  5. Windows Functions • Folder • Mapped drive • Menu bar • Microsoft Exchange - e-mail • My Computer • Network Neighborhood (logged on computers) • Windows Explorer

  6. Configurations - LANs • Severs and workstations • Network operating system • Cabling • Coaxial (10BASE2) • Twisted-pair • Shield twisted-pair • Unshield twisted-pair (10BASET) • Network interface card (NIC) • Punch down

  7. Protocols - I • Packet • Ethernet (Carrier Sense Multiple Access with Collision Detection - CSMA/CD) • Token Ring (Token-pass) • Multistation access unit (MAU - hub) • Transmission Control Protocol/Internet Protocol (TCP/IP) • Session, addressing, routing • NetBEUI - NetBIOS Extended User Interface • No routing • Use TCP/IP

  8. Protocols - II • IPX - Internet Packet Exchange protocol • Xerox • Novell

  9. Topology • Bus • Ring • Star • For Ethernet or token ring • Hub or concentrator for line management • UTP wire

  10. Hardware for NT Server • Compatibility • CPU sizing • Bus speed and expansion slots • Disk storage • SCSI-2 adapters • Memory requirements • Network interface card • CD-ROM drive • Tape drive

  11. Types of Computers • 80486 computers with 25 MHz • Pentium computers -32 bits • Multithreading (one program) • Multitasking (more than one program) • Single-processor computers • Multiprocessor computers • Reduced instruction set computer (RISC) computers - 64-bits

  12. Compatibility • Processor (CPU) • Bus • SCSI adapters and drivers • Video adapters • Network adapters • Audio adapters • Modems • Printers • UPS (uninterrupted power supplies)

  13. CPU Sizing and Bus Speed • CPU speed - Hz (25MHz or higher) • BUS speed - 32-bit to 64-bit • Internal (instruction) and external bus (data) • Bus mastering (I/O processing activities) • Types • Extended Industry Standard Architecture (EISA) 32-bit • Microchannel Architecture (MCA) 32-bit • Peripheral Computer Interface (PCI) 32-bit or 64-bit

  14. Disk Controllers • Interface between disk drives and computer • Data transfer rate • Types • Integrated Device Electronics (IDE) • Enhanced Small Device Interface (ESDI) • Small Computer System Interface (SCSI) • SCSI-1, SCSI-2 narrow, SCSI-2 wide, SCSI-3 wide

  15. Disk Storage • Disk capacity • Disk contention • Speed of individual disks • Speed of disk controllers • Speed of data pathway (bus) to the disks • Number of disk pathway • Disk caching • Disk redundancy • Redundant array of inexpensive drives (RAID)

  16. Memory Requirement • Memory • Server OS - 16 MB • Number of simultaneously access • Amount of memory required by each access • Calculation error • Error checking and correcting (ECC) memory chips • reserved memory for problems • Auto correction for parity error

  17. Network Interface Card • Well-known vendor • IBM, Intel, HP • Ethernet (10 Mbps) or fast Ethernet (100 Mbps) • Auto-configuring cards • No jumpers or dip switches • Hardware interrupts and memory location to use

  18. CD-ROM • SCSI CD-ROM • SCSI-based CD-ROM “jukebox” (hold multiple CD-ROM) • Speed 2X to 8X • 6X or 8X CD-ROM drive • X=150Mbps

  19. Tape Drive • For back up • Types • Quarter-inch cartridge cassette (QIC) • 2-4 GB • Digital audio tape (DAT) • 4-25 GB • Digital linear tape (DLT) • 10-40 GB, damage resistance, longer shelf life, faster

  20. Assignment • Review chapters 1-3 • Read chapters 4-8
