The Virtual Supervisor Module (VSM) is responsible for managing and propagating configurations to the virtual Ethernet modules (VEMs) in a Cisco Nexus 1000V Series switch. The VSM acts as the control point and ensures that configurations are distributed across the switches, maintaining consistency and centralized management.
When configuring FCIP, the two types of acceleration that can be enabled to maximize WAN link utilization are SCSI write acceleration and SCSI tape acceleration. SCSI write acceleration improves the performance of write operations over a WAN by minimizing latency, while SCSI tape acceleration optimizes the performance of tape operations by improving data transfer rates. Utilizing these accelerations helps to enhance the efficiency and speed of data transfers over long distances.
Local policies are applied using Cisco UCS Manager, which allows for management of individual UCS domains. Global policies, on the other hand, are applied using Cisco UCS Central, which provides centralized management and policy implementation across multiple UCS domains.
