Study Notes
Storage Basics
- Storage is any medium that allows for data to be written and retrieved.
- Examples of long-term storage include: USB memory sticks, CDs/DVDs, and hard disk drives (HDDs).
- Solid State Drives (SSDs) utilize flash memory without any moving parts.
- There are four categories of storage access methods:
- Local storage: Only the system where it's installed can access the storage.
- Direct-attached storage (DAS): Refers to HDDs in an enclosure with its own power supply.
- Network-attached storage (NAS): Used for file sharing via standard network protocols.
- Storage area network (SAN): Uses technologies such as Fibre Channel and iSCSI for fast data access.
Disk Storage Properties
- Physical disk properties include: capacity, physical speed, and interface.
- Formatting a disk initializes it with a file system for organizing and storing data.
- Partitioning divides a disk into logical units, each of which can be formatted.
- Boot volume holds the Windows folder, while the system volume contains files for loading the Windows OS.
- The Master Boot Record (MBR) partitioning method limits disk capacity to 2 TB.
- GUID Partitioning Table (GPT) supports disks up to 18 exabytes.
- A simple volume is located on a single disk, whether it's basic or dynamic.
- A mirrored volume (RAID 1) duplicates data on two disks for fault tolerance.
- RAID 5 combines striping and parity information for data recovery in case of disk failure.
File Systems
- NTFS (New Technology File System) is the primary file system used on Windows Servers.
- Windows Server 2012/R2 supports FAT, NTFS, and ReFS.
- FAT32 restricts file size to 4 GB.
- ReFS is primarily used for large file-sharing applications with Storage Spaces.
