    \n
    \n

    Clean installation \u2013 on a computer that either has no OS or on a computer that has an OS that will be overwritten by the installation<\/p>\n

    Upgrade installation \u2013 on a computer that already has an earlier version of the operating system<\/p>\n<\/p>\n

    Most OSs have the Plug and Play (PnP) feature that automatically configures internal and external devices as part of the installation<\/p>\n

    Even with PnP-capable OSs<\/p>\n

    You may have to configure devices to work optimally with the OS<\/p>\n<\/p>\n

    Preparing for installation involves <\/p>\n

    Making sure the computer meets or exceeds the minimum requirements<\/p>\n

    The speed and type of CPU<\/p>\n

    The amount of memory<\/p>\n

    The amount of free disk space<\/p>\n

    Ensuring that all equipment is operating correctly<\/p>\n

    Having all OS installation media available<\/p>\n

    Understanding the general features of the OS you are installing so you can decide which modules to install or omit<\/p>\n

    Having device drivers that might not be included with the OS installation files<\/p>\n

    Having accurate information available about your computer and peripheral devices<\/p>\n

    Being aware of network environment in which you are installing the OS<\/p>\n<\/p>\n

    Installing an OS<\/p>\n

    Where (in which drive, folder, or path) to install the OS and what to name the folder that contains the OS<\/p>\n

    What type of installation you wish to perform (Custom or Upgrade)<\/p>\n

    Information about you, your company, and your computer (computer or workgroup name)<\/p>\n

    Licensing information verifying your right to install the OS<\/p>\n

    Which components of the OS you want to install<\/p>\n<\/p>\n

    Post Install\/Upgrade:<\/p>\n

    After installation, keep the product key, ID number or activation number in a safe place<\/p>\n

    The installation consists of some of the following general functions:<\/p>\n

    Running the installation program<\/p>\n

    Gathering system information<\/p>\n

    Determining which elements of OS to be installed<\/p>\n

    Copying OS files to your computer<\/p>\n

    Configuring devices and drivers<\/p>\n

    Restarting the system and finalizing configuration of devices<\/p>\n<\/p>\n

    3<\/p>\n<\/p>\n<\/div>\n

    Preparation<\/p>\n<\/p>\n

    Installation<\/p>\n<\/p>\n

    Configuration<\/p>\n<\/p>\n

    \n

    Preparing to install Client OS<\/p>\n

    Verify Minimum OS Requirements: CPU, RAM, Storage & Network<\/p>\n

    Confirm Hardware is properly functioning (e.g. keyboard, mouse)<\/p>\n

    Installation Media on hand (e.g. DVD or USB drive)<\/p>\n

    Device Drivers: You may need to install if you have unusual peripherals<\/p>\n

    Storage Configuration: Make sure you install OS on target partitions<\/p>\n

    Username\/Password: local admin or superuser credentials are good<\/p>\n

    Network Environment: IP address connected to LAN for automatic updates or PnP<\/p>\n<\/p>\n

    Virtual Machine Installs: Use similar checklist after you create the VM on your workstation, but no need to check hardware functionality and most installs are performed from network resources.<\/p>\n<\/p>\n<\/div>\n

    \n
    \n

    Preparing for an Upgrade or Migration<\/p>\n<\/p>\n

    Deciding to Upgrade or Migrate<\/p>\n

    Do you or your organization need new functionality that may come with an upgrade?<\/p>\n

    Objective analysis of the situation may show that an upgrade or migration might not be cost effective<\/p>\n

    However, you may want to upgrade to newer hardware for warranty, performance, and reliability; your old OS may not support the new hardware features<\/p>\n

    Experience has also shown that it is best not to upgrade\/migrate shortly after a new OS is released<\/p>\n<\/p>\n

    A migration may be necessary:<\/p>\n

    When you find that your current OS version does not support new software or certain devices you want to use<\/p>\n

    Older OSs don\u2019t have new security features required for safer network and Internet access<\/p>\n<\/p>\n

    4<\/p>\n<\/p>\n<\/div>\n

    \n

    Preparing to install Server OS<\/p>\n

    WINDOWS SERVER: <\/p>\n

    Server Role: determines required services such as DNS, DHCP, Active Directory, etc)<\/p>\n

    Hardware Requirements: CPU, Disk Subsystem, Memory, Hot-add\/Host-add features<\/p>\n

    Design: ServerName, IP Addressing scheme, timezone, Domain\/Workgroup setup<\/p>\n

    WindowServer Edition: Datacenter, Standard, Essentials editions<\/p>\n<\/p>\n

    LINUX\/UNIX SERVER: <\/p>\n

    Similar to Windows: Role, Hardware, Design components<\/p>\n

    Distribution: Choose which LINUX kernel and software package to meet Server role<\/p>\n<\/p>\n

    MacOS SERVER: <\/p>\n

    Apple no longer provides MacOS Server Add-on after OSX 10.6 Snow Leopard (2009)<\/p>\n<\/p>\n<\/p><\/div>\n

    \n
    \n

    Installing Operating Systems<\/p>\n

    Make a Backup Prior to Migrating to new OS <\/p>\n

    Close all open windows and save files to DVD, an external drive or other media<\/p>\n

    Ensure you have the software to restore the backups under the new and old OS<\/p>\n

    LINUX upgrades overwrite config files such as (email, print, windows & network), backups are important.<\/p>\n<\/p>\n

    Perform operating system installations or upgrade:<\/p>\n

    Clean installation \u2013 on a computer that either has no OS or on a computer that has an OS that will be overwritten by the installation<\/p>\n

    Upgrade installation \u2013 on a computer that already has an earlier version of the operating system<\/p>\n<\/p>\n

    Post Install\/Upgrade:<\/p>\n

    Reboot OS: Confirm functionality<\/p>\n

    Check for Updates\/Patches: Apply OS bug fixes, security patches and device drivers<\/p>\n

    \n
    \n

    Input\/Output Devices<\/p>\n

    An OS handles input and output device communications through device drivers (software) and hardware usually provided by device manufacturer<\/p>\n

    Device drivers are often provided with an OS, but the most up-to-date device drivers come directly form each device manufacturer<\/p>\n<\/p>\n

    I\/O Device Categories<\/p>\n

    Random-Access: Allows access to any location of device storage (Disk Drives & RAM)<\/p>\n

    Sequential-Access: Must access storage from start of register (Serial Ports, tape drives, NICs)<\/p>\n

    Character-Stream: Device that transfers data one byte at a time (keyboards, mice, serial ports, sound cards)<\/p>\n

    Block Device: Transfers data in blocks, usually at a fixed size (storage devices, disk drives)<\/p>\n<\/p><\/div>\n

    \n
    \n

    CompTIA Objective 1.12 Install and configure common peripheral devices.<\/p>\n<\/p>\n

    A bad device driver could not only render your device useless, but it can lock up your system.<\/p>\n

    7<\/p>\n<\/p>\n<\/div>\n

    \n
    \n

    Driver & Printer Installations<\/p>\n

    Windows OS<\/p>\n

    Plug and Play (PnP): usually first option for \u201ccheck updates\u201d<\/p>\n

    Windows Wizard: Use when PnP fails<\/p>\n

    Device Manager: Use to install, update, or rollback a device driver<\/p>\n

    Printers: Use the Add Printer Wizard to walk through printer driver install process<\/p>\n<\/p>\n

    Linux Driver Installs<\/p>\n

    Device Special Files: Add file to the \/dev folder using the mknod command<\/p>\n

    3 Special Files: Block special files, Character special files, Named pipes (internal communications)<\/p>\n

    Printers: printtool (Fedora Linux) is common tool\/module to install Printers<\/p>\n<\/p>\n

    MacOS Driver Installs<\/p>\n

    PnP: MacOS comes with drivers for most hardware so simply attach hardware and reboot system<\/p>\n

    DVD\/Software download: When PnP fails<\/p>\n

    Printers: Printer Setup Utility<\/p>\n<\/p><\/div>\n

    Using & Configuring Storage Devices<\/p>\n

    Most uses of computer storage: <\/p>\n

    Operating system files User applications User documents Shared file systems<\/p>\n

    Virtual memory Log files Virtual machines Database storage<\/p>\n<\/p>\n

    Four categories of storage access methods:<\/p>\n

    Local storage \u2013 HDD v SSD \u2013 Direct connectivity computer system board<\/p>\n

    Direct-attached storage (DAS) \u2013 Device connected via external bus interface<\/p>\n

    Network-attached storage (NAS) \u2013 Stand-alone appliance on the Network<\/p>\n

    Storage area network (SAN) \u2013 Large Storage array with high-speed network<\/p>\n<\/p>\n

    Cloud storage<\/p>\n

    Some or all of an organization\u2019s data is stored on servers located offsite and maintained by a storage hosting company<\/p>\n

    Customers can manage storage by assigning permissions for user access<\/p>\n

    Details of managing and backing up storage on local servers are offloaded to a third party<\/p>\n<\/p>\n

    Figure 7-1 A storage area network<\/p>\n<\/p>\n<\/div>\n

    \n
    \n

    CompTIA Obj 1.5 Install and configure storage devices and use appropriate media.<\/p>\n<\/p>\n

    Local storage \u2013 storage media with a direct, exclusive connection to the computer\u2019s system board through a disk controller<\/p>\n

    Almost always inside the computer\u2019s case<\/p>\n

    Usually refers to HDDs or SDDs instead of CD\/DVDs (Hard Disk Drive v Solid State Drive)<\/p>\n

    Provides rapid and exclusive access <\/p>\n

    Disadvantage: only the system where it\u2019s installed has direct access to the storage medium<\/p>\n<\/p>\n

    Direct-attached storage (DAS) \u2013 similar to local storage but can also refer to one or more HDDs in an enclosure with its own power supply<\/p>\n

    A DAS device with its own enclosure and power supply can usually be configured as a disk array<\/p>\n

    Such as a RAID configuration<\/p>\n

    Some DAS have multiple interfaces so that more than one computer can access the storage medium simultaneously<\/p>\n<\/p>\n

    Network-attached storage (NAS) \u2013 has an enclosure, power supply, slots for multiple HDDs, a network interface, and a built-in OS tailored for managing shared storage<\/p>\n

    Sometimes referred to as a storage appliance<\/p>\n

    NAS is typically dedicated to file sharing<\/p>\n

    NAS shares files through standard network protocols such as: Server Message Block(SMB), Network File System (NFS), and File Transfer Protocol (FTP)<\/p>\n<\/p>\n

    Storage area network (SAN) \u2013 uses high-speed networking technologies to give servers fast access to large amounts of shared disk storage<\/p>\n

    Most common network technologies used in SANs are Fibre Channel and iSCSI<\/p>\n

    SANS use the concept of logical unit number (LUN) to identify a unit of storage<\/p>\n

    LUN is a logical reference point to a unit of storage that could refer to an entire array of disks, a single disk, or just part of a disk<\/p>\n<\/p>\n

    Cloud Storage: Examples: Dropbox, Microsoft OneDrive and Google Drive<\/p>\n<\/p>\n

    9<\/p>\n<\/p>\n<\/div>\n

    \n

    Tape Storage \u2013<\/p>\n

    Often used for Disaster Recovery or Business Continuity Purposes with offsite storage<\/p>\n

    Tape backup systems are a traditional choice for backing up large amounts of data<\/p>\n

    With disk drives growing into terabytes, tape drive technology is continuing to evolve in order to keep up<\/p>\n<\/p>\n

    \n
    <\/div>\n
    \n
    \n

    Tapes and Tape Drives<\/p>\n<\/p>\n

    Use magnetic storage and record data in sequential order<\/p>\n

    Disadvantage \u2013 to find a file near the end of the tape, drive must first go through all of the data recorded prior to that file<\/p>\n

    Most popular for long-term storage<\/p>\n

    With disk drives growing into terabytes, tape drive technology is continuing to evolve in order to keep up<\/p>\n<\/p>\n

    DAT Drives \u2013 4mm Digital Audio Tape for archival up to 10 years<\/p>\n

    Uses digital data storage (DDS) format<\/p>\n

    Current standard is DDS-5 \u2013 storage capacity of 36 GB (72 GB compressed)<\/p>\n

    Still used for audio recordings, but use for data storage is mostly replaced by other technologies<\/p>\n<\/p>\n

    DLT Drives \u2013 Half-inch wide Digital Linear Tape<\/p>\n

    Record data in tracks <\/p>\n

    Offers a high-speed search capability <\/p>\n

    Used in many automated tape backup systems<\/p>\n<\/p>\n

    SDLT Drives \u2013 Super digital linear tape<\/p>\n

    Use both magnetic and optical recording methods<\/p>\n

    Laser technology can more accurately write data to the tape and allows for greater density of information<\/p>\n

    DLT\/SDLT have an archival life of up to 30 years<\/p>\n<\/p>\n

    AIT Drives \u2013 Advanced intelligent tape (AIT)<\/p>\n

    Used mainly in midrange servers<\/p>\n

    Tapes have an erasable memory chip inside the cartridge that stores information normally written at the beginning of the tape<\/p>\n

    Can fast forward and pinpoint information faster<\/p>\n

    S-AIT Drives \u2013 Super advanced intelligent tape Has a capacity of 500 GB\/1.3 TB (native\/compressed)<\/p>\n

    Both of these drives can sustain up to 30,000 tape passes and have an archival life of 30 years<\/p>\n<\/p>\n

    LTO Drives \u2013 Linear tape open<\/p>\n

    Most widely accepted in high-end servers (because of high-speed performance)<\/p>\n

    Standards are open to the public and are nonproprietary<\/p>\n

    Fast data transfer speed up to 240 MBps (noncompressed data) and 120 MBps (compressed data)<\/p>\n

    Can sustain up to 260 tape passes and have an archival life of 15-30 years<\/p>\n<\/p>\n

    Ch 8 Virtualization & Cloud Computing<\/p>\n

    Virtualization \u2013 Process that creates a software environment to emulate a computer\u2019s hardware and BIOS, allowing multiple OSs to run on the same physical computer at the same time<\/p>\n

    Common Terms:<\/p>\n

    Virtual Machine (VM) \u2013 virtual environment that emulates a physical computer<\/p>\n

    Virtual Disk \u2013 consists of files on host computer that represents VM hard drvie<\/p>\n<\/p>\n

    HyperVisor \u2013 software that enables multiple VMs to share physical hardware resource:<\/p>\n

    Type 1 -Bare-metal virtualization products are targeted mainly for production virtualization in data centers using products such as Citrix XenServer or VMware vSphere.<\/p>\n

    Type 2 -Hosted virtualization products are installed on a desktop OS and include VMware Workstation, Virtual PC, and VirtualBox<\/p>\n<\/p>\n

    <\/div>\n
    \n
    \n

    CompTIA Objective 2.2 \u2013 Given a scenario, setup and use client-side virtualization <\/p>\n<\/p>\n

    Hosted Virtualization<\/p>\n<\/p>\n

    Has an advantage of supporting a wider variety of guest OSs because there are few incompatibility problems between the guest OS and hardware<\/p>\n

    Easy and straightforward to use<\/p>\n

    Just install the software on your computer and begin creating virtual machines<\/p>\n

    Only hardware requirement is enough memory to support the host and guest OSs, adequate CPU power, and enough space to store the virtual disk <\/p>\n

    Well known hosted virtualization products:<\/p>\n

    VMware Workstation Pro<\/p>\n

    VMware Workstation Player<\/p>\n

    Microsoft Virtual PC<\/p>\n

    VirtualBox<\/p>\n<\/p>\n

    Bare-Metal Virtualization Applications<\/p>\n

    Consolidate servers<\/p>\n

    Retire old or unreliable hardware: converting physical machines to VMs<\/p>\n

    Make optimal use of multicore, high-performance servers<\/p>\n

    Maintain application separation<\/p>\n

    Reclaim rack or floor space<\/p>\n

    Reduce cooling and power requirements<\/p>\n<\/p>\n

    Bare-Metal Virtualization Products<\/p>\n

    Citrix XenServer \u2013 Uses Linux as a management OS on the host<\/p>\n

    A XenServer host computer requires a 64-bit CPU with virtualization extensions to run Windows guest OSs<\/p>\n

    VMware vSphere \u2013 includes VMware ESX Server, which is installed directly on the physical server without a management OS<\/p>\n

    Most configuration tasks are performed from a remote client OS using vSphere Client<\/p>\n<\/p>\n

    Cloud Computing<\/p>\n

    Benefits:<\/p>\n

    Reduced physical plant costs<\/p>\n

    Reduced upfront costs<\/p>\n

    Reduced personnel costs<\/p>\n<\/p>\n

    Three main categories of cloud computing: <\/p>\n

    SaaS \u2013 also called \u201chosted applications\u201d or \u201con-demand applications\u201d<\/p>\n

    Most well-known example is Google Apps and Microsoft Office 365<\/p>\n

    Usually offered as a subscription based on the number of users<\/p>\n

    Customers can take advantage of new software editions much faster<\/p>\n

    Available anywhere the customer has a connection to the Internet<\/p>\n<\/p>\n

    PaaS \u2013 also called \u201chosted platform\u201d and is similar to SaaS, but customer develops applications with the service provider\u2019s tool and infrastructure<\/p>\n

    Customer develops and owns the application and then delivers it to a third party<\/p>\n

    The most common PaaS products are:<\/p>\n

    Salesforce.com\u2019s Apex<\/p>\n

    Azure for Windows<\/p>\n

    Google\u2019s AppEngine for Python and Java<\/p>\n

    WaveMaker for Ajax<\/p>\n

    Engine Yard for Ruby on Rails<\/p>\n<\/p>\n

    IaaS \u2013 also called \u201chosted infrastructure\u201d, it allows a company to use storage or entire virtual servers<\/p>\n

    If a customer needs another 100 GB of storage space they can pay for the space without worrying about how that space is actually provided<\/p>\n

    If a customer needs another server they pay for the amount of processing and storage the additional server actually requires <\/p>\n

    Customers rent the resources they are using<\/p>\n<\/p>\n

    Private Cloud Versus Public Cloud<\/p>\n<\/p>\n

    Private cloud services <\/p>\n

    When a company delivers cloud services to their own employees through the use of virtualization technologies<\/p>\n

    Deployed from the company\u2019s own data center<\/p>\n

    Examples of virtualization technologies:<\/p>\n

    VMware and Microsoft Hyper-V<\/p>\n

    Public cloud services<\/p>\n

    Cloud services delivered by a third-party provider<\/p>\n<\/p>\n

    11<\/p>\n<\/p>\n<\/div>\n

    \n

    Ch 8 Virtualization & Cloud Computing<\/p>\n

    Cloud computing is a computing model in which data, applications, and processing power are managed by servers on the Internet<\/p>\n

    Benefit: Lower physical plant costs, upfront deployment costs and ongoing personnel costs<\/p>\n<\/p>\n

    Three main categories of cloud computing: <\/p>\n

    Software as a Service (SaaS) \u2013 hosted or on-demand applications<\/p>\n

    Platform as a Service (PaaS) \u2013 hosted platform allows development on provider\u2019s tools\/resources<\/p>\n

    Infrastructure as a Service (IaaS) \u2013 hosted infrastructure (storage, desktops, etc)<\/p>\n<\/p>\n

    Private v Public Cloud<\/p>\n

    Private: Cloud services internal to a company through use of virtualization technologies that is NOT available to public domains.<\/p>\n

    Public: Cloud service provided by a third-party vendor and readily accessed via Internet connectivity.<\/p>\n<\/p><\/div>\n
