For Server and Client Network Access
An access switch enables the server to access the network, the Internet or other servers for data or storage for data. The access-layer network infrastructure consists of modular switches, fixed-configuration 1 or 2 RU switches, and integral blade server switches.
Switches provide both Layer 2 and Layer 3 features fulfilling the various server broadcast domain or administrative requirements. Dell recommends deploying access switches in pairs to provide redundant connectivity to servers.
When designing an access layer, consider the following features:
- Connectivity of 1 or 10 Gigabit Ethernet (GbE) — 10GbE connectivity can future-proof your investment as the demand on your network grows.
- Stacking — The ability to stack your access switches can simplify management and improve reliability.
- Performance/Reliability — Redundant power and fans can provide greater reliability; line-rate performance is critical, especially in virtualized environments.
