PowerShell Script To Check Memory And Disk Space
Over the next 12 months, your company will be installing several new internally developed software applications and upgrading several others. You have been assigned the task of planning the deployment of these applications throughout the network. Your task for this project is to develop a software deployment plan with a focus on how scripting can be used to minimize the labor required to complete the deployments. The tasks you will plan for are as follows: 1) Give all users on the network the ability to download and install Software Application A, Software Application B, and Software Application C, which are new, internally developed applications that have never been installed on any of the network workstation computers.
Users should only be allowed to download Application A if they are in the sales or marketing departments, Application B if they are in engineering or IT, or Application C for all others. Users who elect to download the software must first have their system checked to make sure it has at least 2 GB of memory and 250MB of free disk space, and then successful installations must be recorded in a network-based database. 2) Determine which users on the network do not have the latest version (3.0) of internally developed Software Application D. E-mail users in need of the update, providing them with a download link where they can install the update. Record successful updates in a network-based database.
3) Prepare a document to submit your work: A. Use Word. B. Title page a) Course number and name b) Project name c) Student name d) Date C. Task 1: Software installation: a) Identify each subtask. b) Discuss if and how scripting can be used to help complete each subtask. c) Select appropriate scripting languages for subtasks that can be scripted, and justify your selection.
D. Task 2: Software update: a) Identify each major subtask. b) Discuss if and how scripting can be used to help complete each subtask. c) Select appropriate scripting languages for subtasks that can be scripted, and justify your selection. E. Provide well-documented source code for at least 1 of the subtasks for Task 1 or Task 2.
Paper For Above instruction
The deployment and updating of software applications across a company network is a complex but manageable task that benefits significantly from automation strategies such as scripting. This paper explores a comprehensive plan to deploy new applications and update existing ones within an organizational infrastructure, emphasizing scripting techniques to streamline processes and reduce manual labor.
Task 1: Software Installation
Subtask Identification
The initial phase involves several key subtasks: user authorization based on department, system compatibility checks, software download, installation execution, and logging of installation success.
- Authorization control: Ensuring only authorized personnel can download specific applications.
- System requirement verification: Checking if each user's workstation meets minimum hardware specifications.
- Software download and installation: Facilitating user-initiated downloads and automated installations.
- Logging installation status: Recording successful installation events in a centralized database.
Use of Scripting and Justification
Scripting can be employed at multiple points in this process to automate repetitive tasks, enforce policies, and improve accuracy. For example, batch scripts or PowerShell scripts can handle the validation and deployment tasks transparently to users.
Selection of Scripting Languages
PowerShell is a prime candidate for Windows-based networks due to its extensive system administration capabilities, ease of use, and integration with Windows Management Instrumentation (WMI). PowerShell can perform hardware checks, manage downloads, execute software installations via silent modes, and record logs directly into database systems with appropriate modules or commands.
Task 2: Software Update
Major Subtasks Identification
- Version verification: Identifying users with outdated software (version 3.0)
- Notification and communication: Sending emails with update links.
- Update download and installation: Facilitating user updates through links or scripts.
- Logging update success: Recording completion in the network database.
Use of Scripting and Justification
Automated scripts enable mass verification of software versions across the network, bulk email notifications, and streamlined deployment processes. Scripting ensures prompt identification and communication, with minimal manual oversight, leading to efficient management.
Selection of Scripting Languages
PowerShell again serves effectively here because it can query installed software versions remotely, send emails via SMTP, and initiate downloads or silent updates. Its integration with Active Directory and Group Policy enhances centralized control.
Sample Scripting Code
PowerShell Script for Checking System Hardware Specifications
PowerShell script to check memory and disk space
$minMemoryGB = 2
$minFreeDiskMB = 250
$computerName = $env:COMPUTERNAME
Get total physical memory
$mem = Get-CimInstance Win32_ComputerSystem | Select -ExpandProperty TotalPhysicalMemory
$memGB = [math]::Round($mem / 1GB, 2)
Get free disk space on C:
$disk = Get-CimInstance Win32_LogicalDisk -Filter "DeviceID='C:'"
$freeSpaceMB = [math]::Round($disk.FreeSpace / 1MB, 2)
Check conditions
if ($memGB -ge $minMemoryGB -and $freeSpaceMB -ge $minFreeDiskMB) {
Write-Output "$computerName meets the system requirements."
} else {
Write-Output "$computerName does not meet the system requirements."
}
This script automates system checks before software installation, ensuring compliance with hardware specifications efficiently across the network.
Conclusion
Effective deployment and update strategies hinge on leveraging scripting languages, particularly PowerShell, due to their flexibility, power, and integration with Windows environments. Automating checks, downloads, installations, notifications, and logs minimizes manual effort, improves accuracy, and accelerates deployment timelines, thereby supporting organizational agility and technological advancement.
