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 B-Series Servers The Cisco UCS B-Series blade servers have also gone through multiple generations. At the time of writing this chapter, the current generations available are the fifth (M5) and the sixth (M6). The Cisco UCS servers either have a two-CPU socket mainboard or a four-CPU socket mainboard. To distinguish between them and […]
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 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 […]
Cisco Fibre Channel NPV Mode The Fibre Channel NPV is another SAN virtualization option available in the data center. It solves the challenge due to the limit on the domain IDs that can be used in a SAN fabric. The NPV is a mode in which a Fibre Channel switch operates. In this mode, the […]
Cisco HyperFlex Data Platform Hyperconverged infrastructure (HCI) combines compute, virtualization, storage, and networking in a single cluster. Starting with as few as three nodes, users can easily scale out to match computing and storage resource needs. Hyperconvergence brings cloudlike simplicity on-premises and within a single, easily managed platform. Nowadays, the organizations must meet the challenges […]
Fibre Channel Zoning The concept of using zones and zoning is the basic security mechanism in the Fibre Channel Protocol standard. With the many different types of servers and storage devices on the network, the need for security is crucial. For example, if a host were to access a disk that another host is using, […]
Cisco UCS Fabric Interconnect Product Overview The Cisco Fabric Interconnect is a core part of Cisco UCS. Here’s an overview of Cisco UCS Fabric Interconnect: The Cisco UCS Fabric Interconnects are now in their fourth generation. The Cisco UCS 6100 Fabric Interconnects were the first generation. They are no longer supported or sold. The second […]
DCBX Protocol The PFC and the ETS provide the means to divide, mark, and control the traffic and the bandwidth used, but there is still the need for these parameters and capabilities to be exchanged and negotiated between the devices in the converged infrastructure. The devices need to support the same standards. They need to […]
Fibre Channel IDs Besides the physical WWN addresses, there is also a second addressing mechanism. It can be called logical, as the addresses are not hard-coded in the hardware; instead, they are generated by the switched fabric and assigned to the FC devices. These addresses are called Fibre Channel IDs (FCIDs) and are used for […]
