Cisco UCS 6248UP 48-Port Fabric Interconnect

The Cisco UCS 6248UP 48-Port Fabric Interconnect is the central backbone of the Cisco Unified Computing System, delivering high-density connectivity and unified management for modern data centers. Designed to support dense server deployments, virtualization, and cloud-ready workloads, this 1U appliance provides line-rate, low-latency, lossless 10 Gigabit Ethernet networking with Fibre Channel over Ethernet (FCoE) integration. With 48 fixed Fabric ports, the 6248UP consolidates LAN and SAN traffic, reduces cabling complexity, and streamlines operations under Cisco UCS Manager, enabling defender-grade security, policy-driven automation, and scalable performance for today’s enterprise applications.

• Unified management and policy-driven automation - The Cisco UCS Manager centralizes control of compute, network, and storage resources, enabling administrators to define and enforce policies across the entire UCS domain. Service profiles map hardware configurations to logical identities, so deploying new blades or rack servers with consistent settings becomes quick and repeatable. Firmware baselines and policy-based upgrades reduce downtime and compatibility issues; automated health checks, inventory tracking, and compliance enforcement ensure governance at scale. The 6248UP also integrates with CIMC for out-of-band management and with Cisco Intersight for cloud-based analytics, AI-driven insights, and proactive remediation, helping teams operate more efficiently while maintaining security and auditability through role-based access control and detailed logs.
• High-performance, low-latency fabric - This interconnect delivers line-rate, low-latency, lossless 10 GbE with Fibre Channel over Ethernet (FCoE) support, enabling converged networks that carry server, storage, and management traffic over a single fabric. It handles bursts from virtualization platforms and dense storage I/O without congestion, preserving application performance and reducing jitter for VMs, databases, and I/O-intensive workloads. Built-in QoS and traffic-engineering features allow prioritization of latency-sensitive workloads such as VDI and real-time analytics, while non-critical traffic like backups and management remains efficiently managed. Overall, the 6248UP supports scalable density without sacrificing performance or reliability in virtualized data centers.
• Reliability and resilience built in - Cisco UCS fabric interconnects are engineered for continuous operation, featuring redundant power supplies, hot-swappable fans, and fault-tolerant fabric interconnect clustering. In event of component failure, traffic automatically re-routes through alternate paths with minimal disruption, preserving data integrity and service uptime. Centralized health monitoring and proactive alerts in UCS Manager enable rapid identification and remediation of issues. Automatic firmware health checks, Non-Stop Forwarding behavior, and non-disruptive maintenance options help IT teams keep systems up-to-date while minimizing maintenance windows and business impact.
• Scalability and flexible deployment - The 6248UP is designed to scale with growing data centers and expanding virtualization footprints. It supports clustering with other fabric interconnects to form highly available, scalable fabrics that preserve policy consistency and network connectivity as you add servers. The unified fabric approach reduces cable sprawl by consolidating LAN and SAN traffic, enabling simpler topologies and easier cabling as you scale out. Whether deploying a private cloud, a virtualization-first infrastructure, or a hybrid cloud strategy, the 6248UP adapts to your topology, allowing non-disruptive growth and prudent, forward-looking capacity planning.
• Broad compatibility and ecosystem - As part of the Cisco UCS platform, the 6248UP integrates with a broad ecosystem of hypervisors, storage arrays, and cloud-management tools. It supports VMware vSphere, Microsoft Hyper-V, OpenStack, and Kubernetes through UCS Manager, standard APIs, and robust CLI. The UCS architecture promotes consistent policy enforcement across compute, network, and storage layers, enabling faster deployments and easier lifecycle management. With validated reference architectures and extensive Cisco ecosystem partnerships, organizations can align their infrastructure with best practices for virtualization, data center modernization, and hybrid cloud adoption.

How to Install Cisco UCS 6248UP 48-Port Fabric Interconnect

• Preparation: Confirm data center readiness, including rack space (1U), sufficient power (with redundancy), cooling capacity, and network topology aligned with UCS Manager design. Gather credentials, licensing, and firmware baselines required for deployment. Prepare the management networks and ensure access to UCS Manager or CIMC for initial configuration. Plan the service profile strategy and policy sets to be applied during the rollout.
• Rack mounting and cabling: Mount the 6248UP securely in a standard 19-inch rack, attach it to the rack rails, and connect redundant power feeds. Route cables cleanly to avoid blocking airflow and ensure stable, organized cabling for future maintenance. Verify that all network uplinks and service connections are correctly labeled to support straightforward management and troubleshooting.
• Initial configuration: Power on and access the CIMC or UCS Manager interface. Verify hardware health, configure management IPs, and establish basic policies. Set firmware baselines, define organization-wide standards, and ensure access controls are in place before proceeding with deeper network and server policy configuration.
• Policy and profile setup: Create service profiles for servers, define network policies (VLANs, NIC teaming, VLAN tagging, and QoS rules), and configure storage networking (FCoE or FC where applicable). Bind service profiles to the appropriate blade or rack servers, ensuring consistent hardware-to-identity mappings and rapid deployment capability for new workloads.
• Validation and maintenance: Validate connectivity with test workloads, monitor health dashboards, and enable alerting for critical metrics. Perform firmware updates as needed using policy-driven upgrades, and document changes for audit trails. Establish routine maintenance procedures and backup configurations to minimize risk during future upgrades or expansions.
