Comparison of Storage Architectures: Traditional, SAN, NAS PPT

This PPT slide, part of the 91-slide Computer Industry Analysis Training PowerPoint presentation, presents a comparative analysis of 3 distinct storage architectures: Traditional (server-attached storage), Storage Area Network (SAN), and Network Attached Storage (NAS). Each architecture is visually represented, highlighting their structural differences and key components.

In the traditional approach, storage is directly attached to servers, which can limit scalability and flexibility. This model typically involves a straightforward setup with servers connected to storage devices via a switch. The diagram indicates the use of WAN and Ethernet hubs, suggesting a more localized network structure that may not efficiently handle large data volumes.

The SAN model introduces a more sophisticated architecture. It employs a Fibre Channel switch, which allows multiple servers to access a shared pool of storage. This design enhances performance and scalability, making it suitable for environments with high data demands. The SAN configuration is depicted with connections to both WAN and LAN, indicating its capability to manage data across broader networks.

On the other hand, NAS offers a different approach by connecting storage devices directly to a network. This architecture is designed for ease of access and file sharing among multiple users. The slide illustrates how NAS integrates with existing network infrastructure, utilizing routers and switches to facilitate data flow.

Overall, the slide effectively outlines the strengths and weaknesses of each storage architecture, providing valuable insights for decision-makers considering their storage options. Understanding these differences can guide organizations in selecting the right solution based on their specific needs and growth projections.
