Study Notes
Data Center Fundamentals
- A data center's primary purpose is to provide a secure and efficient environment for storing, processing, and distributing data.
Storage Security and Access
- Storage administrators ensure secure access to storage devices by implementing zoning, which restricts initiators' connectivity to targets in a SAN fabric.
- Secure access to storage devices is also achieved through the use of authentication, authorization, and accounting (AAA) protocols.
Protocols and Technologies
- VRRP stands for Virtual Router Redundancy Protocol, which provides redundancy for virtual routers in a network.
- FCoE (Fiber Channel over Ethernet) is a technique that encapsulates Fibre Channel frames over Ethernet networks, employing a technique called encapsulation.
- FCoE encapsulates Fibre Channel protocol.
- iSCSI is a protocol that encapsulates storage requests into a protocol that can be routed over a LAN.
- Block-based storage protocols include Fibre Channel Protocol (FCP) and iSCSI.
Nexus Switches and FabricPath
- During the initial setup of a Nexus 7000 switch, virtual device contexts (VDCs) and VLANs are configured.
- Universal ports on a Nexus switch support multiple protocols, including Fibre Channel, FCoE, and Ethernet.
- FabricPath is a technology that reduces the cost, power, and cooling requirements in the data center by providing a scalable and flexible network architecture.
- The primary function of FabricPath is to provide a scalable and flexible network architecture.
Data Center Model and Service Modules
- Data center service modules connect at the aggregation layer of the data center model.
- The purpose of a Data Center service module is to provide a modular and scalable approach to building data center infrastructure.
Converged and Unified Fabric
- FCoE and iSCSI are part of a converged fabric.
- FCoE and Ethernet are part of a unified fabric.
Redundancy Protocols
- VRRP is a standards-based First Hop Redundancy Protocol that serves as a Cisco-supported alternative to Hot Standby Router Protocol (HSRP).
