Анализ и оценка систем адресации данных в современных ЭВМSergey Gerasimov
Часть операционной системы, которая «отвечает» за корректное хранение данных и предоставление доступа к ним пользователю и прикладным программам
Порядок, определяющий способ организации, хранения и именования данных на носителях информации ИТ-оборудования
Система адресации данных является одной из самых существенных составных частей файловой системы. Именно система адресации позволяет находить нужный файл среди множества как пустых, так и занятых блоков на диске.

NTFS is a file system introduced by Microsoft in 1993 for Windows NT operating systems. It improved on previous file systems with features like larger storage capacity support, redundancy, security, and performance improvements important for businesses. NTFS formats volumes with system files including the Master File Table that stores metadata for all files and folders. It provides security, compression, encryption and other advanced features through file attributes. NTFS also supports features like sparse files, recoverability, and alternate data streams.
ReFS is a new file system developed by Microsoft as an advancement to NTFS. It provides high data availability, prevents data corruption, and supports large volumes of storage up to petabytes in size. ReFS uses checksums and auto-repair to ensure data integrity and resilience. While it improves upon NTFS in areas like storage capacity and self-healing of data errors, ReFS lacks some features of NTFS like deduplication, compression, and hard links.

This presentation was given by Seema Kumar, Websphere Product Management and Surya V Duggirala, Websphere Performance Architect at IBM Impact 2012 at Mumbai on the 1st of June. It talks about Innovative Applications and Interactive Experiences
The document discusses file systems and their components. It describes how files are organized logically and mapped to physical storage. It covers key file system concepts like directories, file allocation schemes, file attributes, and file operations. It also summarizes common file systems like FAT, FAT32, and NTFS and compares their features such as supported drive sizes, cluster sizes, and compatibility with different operating systems.
This document discusses using Microsoft Azure to provide high availability and disaster recovery for SQL Server databases. It covers:
- Using Azure virtual machines, disks, and images to host SQL Server databases in Azure.
- Configuring availability sets, fault domains, and update domains to ensure SQL Server virtual machines are highly available.
- Implementing load balancing across SQL Server instances for availability and disaster recovery across multiple Azure regions.
- Demonstrating high availability and multi-datacenter disaster recovery for SQL Server using internal load balancers in Azure.
Dmytro IELKIN presented on developing a distributed Azure application alone. He discussed starting with a simple ASP.NET MVC website and database, using Azure Web Jobs for background tasks triggered by queues, implementing real-time notifications with SignalR and web sockets, scaling the website and SignalR with auto-scale, scaling out, CDN, and traffic manager, using deployment slots for deployment and database migration, and analytics with Application Insights for page views, exceptions, and custom event tracking. He concluded by encouraging the audience to visit azure.microsoft.com to get started.
This document provides examples of using PowerShell Desired State Configuration (DSC) to deploy and manage virtual machines (VMs) in Microsoft Azure. It demonstrates how to install DSC, configure a VM with DSC, upload the configuration to Azure storage, apply the configuration to a VM, and check the status. Key steps include selecting an Azure subscription, creating a storage account, publishing and applying the DSC configuration to a VM, and updating the VM. Additional examples show creating availability sets and load balancers when deploying the VM.
Better Together: Microsoft Azure Virtual Machines & PowerShell Desired State ...Oleg Chorny
In this session you'll be introduced to the modern way of configuring Microsoft Windows Server using Powershell Desired State Configuration (DSC) and learn how DSC could be applied to any Virtual Machine in the Microsoft Azure to gain more consistency and velocity.
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms.
