Describing Cisco UCS Components
Cisco UCS X-Series Modular System The Cisco UCS X-Series Modular system, shown in Figure 16-17, is the latest generation of the Cisco UCS. Here are the major new features: Figure 16-17 Cisco UCS X-Series Modular System The new Cisco UCS X9508 chassis provides a new and adaptable substitute for the first generation of the […]
Cisco UCS C-Series Servers and the Cisco IMC Supervisor Cisco UCS C-Series rack servers deliver unified computing in a rack-mount form factor. The Cisco UCS C-Series rack server family offers an entry point into unified computing. Cisco UCS C-Series rack servers offer the flexibility of standalone management or can be integrated as part of a […]
Cisco Fibre Channel NPIV Feature The first of the two storage virtualization technologies that will be discussed is the NPIV feature. What exactly is the challenge and why do you need to know about it? In a typical physical design, there is a server, or the initiator, that connects to a Fibre Channel switch through […]
Cisco UCS S-Series Storage Server The Cisco UCS S3260 storage server, shown in Figure 16-15, is a modular, high-density, high-availability, dual-node storage-optimized server that is well-suited for service providers, enterprises, and industry-specific environments. It provides dense, cost-effective storage to address your ever-growing data needs. Designed for a new class of data-intensive workloads, it is simple […]
PLOGI Process After a successful FLOGI process, the N_Port can communicate in the switched fabric. This means sending FC frames to another FC node. That other FC node (either an initiator or target) is connected to the fabric through an N_Port as well. As you already know, FCP is a protocol that is focused on […]
Fabric Shortest Path First The FC Protocol uses Fabric Shortest Path First (FSPF) to provide the routing functions. This protocol establishes communication with the other switches in the switched fabric using a Hello protocol. The Hello protocol is also used for the FC switches to exchange the FSPF parameters and capabilities. The FSPF protocol maintains […]
Cisco UCS Components As discussed in previous chapters, data centers are built using different components that represent the physical infrastructure, the layers of operating systems and virtualization, and the different software and applications that provide the needed services, as well as the components used to build and manage the needed level of security and to […]
Fibre Channel Physical Addressing Two types of physical addresses are used in the Fibre Channel Protocol. The World Wide Names (WWNs), also known as World Wide Identifiers (WWIDs), are the physical addresses used in FCP communication. The WWNs are similar in concept to the Media Access Control (MAC) addresses in the Ethernet communication. WWNs have […]
