Storage and data management are critical components of IT infrastructure, ensuring that data is stored, organized, protected, and accessible efficiently. Here’s an overview of key concepts:
- Direct Attached Storage (DAS): Storage directly connected to a single server (e.g., HDDs, SSDs, NVMe).
- Network Attached Storage (NAS): Storage connected to a network, accessible by multiple devices via file-level access.
- Storage Area Network (SAN): A high-speed network of storage devices providing block-level access to multiple servers.
- Cloud Storage: Remote storage solutions offered by providers like AWS S3, Azure Blob Storage, and Google Cloud Storage.
- Fibre Channel (FC): High-performance SAN storage protocol.
- iSCSI (Internet Small Computer System Interface): Block storage over TCP/IP networks.
- NFS (Network File System): File-sharing protocol for Linux/Unix environments.
- SMB/CIFS (Server Message Block/Common Internet File System): Windows-based file-sharing protocol.
- Data Lifecycle Management (DLM): Managing data from creation to archival.
- Backup & Recovery: Ensuring data protection through snapshots, replication, and backups.
- Tiered Storage: Categorizing data into different storage classes based on access frequency.
- Deduplication & Compression: Optimizing storage usage by removing duplicate data and reducing file sizes.
- Software-Defined Storage (SDS): Decoupling storage hardware from management, providing flexibility.
- Hyper-Converged Infrastructure (HCI): Combining compute, storage, and networking in a single solution.
- Hybrid Storage: Combination of on-premises and cloud storage.
- Multi-Cloud Storage: Using multiple cloud providers to enhance availability and redundancy.
