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

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)

Alternative Server Systems Novell - NetWare DEC - PATHWORKS

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

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

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

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

Protocols - II IPX - Internet Packet Exchange protocol Xerox Novell

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

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

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

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

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

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

Disk Storage Disk capacity Disk contention Disk redundancy 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)

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

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

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

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
