SAN Configurations

This chapter introduces the components that you can include in your Storage Area Network (SAN). It also explains the different operating system environments and configurations that you can use in your SAN.

SAN Components

The following sections describe the various components in a SAN.

Servers

In a SAN, servers provide the attached client systems with access to high throughput, reliable storage systems. Servers also manage the storage systems and attached SAN appliances.

When you are installing, configuring, managing, or maintaining a server in a SAN, you must consider both the installed operating system, software, and storage that is being used on or by that server.

Server Software

The server software that is required on each server varies by the type of storage sys- tem it is using and by whether it is using a SAN Appliance.

Servers Accessing Storage Systems Directly

Ensure that each host server that is only accessing storage systems directly and not through a PowerVault 530F SAN appliance, such as the server in Figure 2-1, has the following software installed:

Dell OpenManage Data Managed Node Data Agent (for 650F and 651F only)

Dell OpenManage Storage Consolidation (for 650F, 651F and 660F)

Dell OpenManage Application Transparent Failover (ATF) (for 650F and 651F only)

QLogic QLdirect (for 660F only)

Dell OpenManage Array Manager (for 650F, 651F and 660F)

650F, 651F specifications

The Dell 651F and 650F are notable entries in the Dell family of networking switches, designed to meet the increasingly demanding requirements of modern enterprises. Built to enhance network performance and reliability, these switches embody a variety of features and technologies that cater to both small businesses and large organizations.

At the heart of the Dell 651F and 650F is their robust hardware architecture. Both models come equipped with high-performance processors, enabling them to efficiently handle substantial data traffic. The Dell 651F features a higher port density compared to the 650F, making it ideal for environments where connectivity and bandwidth are critical. Each switch supports multiple 10G and 25G SFP+ ports, providing flexibility for organizations that require scalable network solutions.

One of the standout characteristics of these switches is their advanced Layer 3 routing capabilities. This feature allows for more precise traffic management, enhancing overall network efficiency. Additionally, both models support various routing protocols, including OSPF, BGP, and RIP, enabling them to seamlessly integrate into existing IT infrastructures.

Security is a primary concern for any organization, and Dell has taken significant measures to address it in the 651F and 650F switches. They support 802.1X authentication and have built-in Access Control Lists (ACLs), helping to safeguard sensitive data while preventing unauthorized access. Furthermore, both models are compliant with various industry standards, ensuring that they can protect networks against emerging threats.

Management and monitoring features also play a crucial role in the functionality of these switches. The Dell Networking OS provides an intuitive interface, which simplifies configuration and management tasks. With features like simple command-line interface (CLI) access and a web-based GUI, network administrators can easily troubleshoot and optimize performance.

In terms of power efficiency, the Dell 651F and 650F are designed with energy-saving technologies that minimize operational costs. They support Power over Ethernet (PoE), allowing for the connection of various devices without the need for separate power sources.

In conclusion, the Dell 651F and 650F switches represent a powerful combination of performance, security, and efficiency. Their advanced features, versatile connectivity options, and user-friendly management tools position them as an excellent choice for organizations looking to enhance their networking capabilities. As businesses continue to evolve and demand more from their technology, Dell’s offerings remain ready to meet those needs.
