Chapter 10: Manage Storage Service

10.1 Manage Storage Service - Configure Disk and Volumes

Skill Overview

• Manage disks and volumes: Settings for disk management involve creating or configuring partitions and volumes effectively.

• Configure volumes: Ensure that volumes are set up to be usable within systems for data storage.

Key Terms

• Partition: A logical division of a storage device (like a hard drive).

• Volume: A logical area within a file system where data is stored.

• Format: Prepares a volume for a file system, allowing data to be saved properly.

• Folder/Directory: A container in a volume that holds files or other folders.

• File: A logical unit of data treated as a single entity.

Partitions, Volumes, and File Systems

• Partitions: Divisions of a storage device prepared to save data.

• Volumes: Logical storage areas created within partitions.

Key Features of NTFS

• NTFS (New Technology File System) supports large disks and file sizes.

  • Offers features such as data compression, encryption, disk quota restrictions, and file/folder permissions.

MBR and GPT Partitioning

• MBR (Master Boot Record):

  • Consists of the first 512 bytes on a disk.

  • Limits to four primary partitions and a maximum of 2 TB per partition.

  • Supports only basic partitions with a limit of 128 per disk.

• GPT (GUID Partition Table):

  • Supports much larger disks and is more fault-tolerant.

Disk Preparation

• Steps include installing operating systems, initializing partitions, and using Disk Management tools.

Volume Management

• Includes types of volumes:

  • Simple Volumes

  • Spanned Volumes

  • Striped Volumes

  • Mirrored Volumes

  • RAID 5 Volumes

  • Features such as moving and resizing volumes or recreating them if needed.

Managing Storage Spaces

• Logical drives created from physical storage devices for user data storage.

• Storage Pools: Places where physical disks are grouped for use in storage spaces.

Storage Replica

• A Windows Server feature for replicating data between servers for disaster recovery, with synchronous and asynchronous options for different latency environments.

  • Synchronous Replication: Low-latency networks with immediate data replication.

  • Asynchronous Replication: Handles higher latency environments.

Data Deduplication

• A feature aimed at saving physical space by eliminating duplicate data using chunking and compression methods.

  • Benefits include optimized storage usage, reduced costs, improved performance, and data integrity.

Storage Performance Management

• SMB Direct: Enables efficient data transfers between servers with minimal CPU load.

  • SMB Multichannel: Facilitates multiple network connections for data operations.

  • Storage Quality of Service (QoS): Monitors and manages storage performance effectively.

Configuring File Systems

• Focus on NTFS permissions, quotas, and permission inheritance for effective file management.

• Permissions: Control access at various levels (explicit, inherited, etc.) and are critical for security.

NTFS Permission Troubleshooting

• Involves calculating effective permissions, understanding the impact of moving and copying files, and managing access control lists (ACLs).

• Understand how changes in permissions affect access levels to ensure proper data security and integrity.
