Features
- The PowerConnect 6248 is one of Dell’s most advanced switch offerings with advanced core switching capabilities for the small to medium enterprise. This 48-port Giga bit Ethernet Layer 3 switch is stackable and offers optional 10 Gigabit Ethernet uplinks and supports the latest version of the Internet Protocol—IPv6—enabling broader worldwide scalability. High performance stacking is supported for up to twelve systems, and advanced security and Quality of Service (QoS) features make this switch ideal for applications such as Voice over IP, Layer 3 routing, High Performance Cluster Computing (HPPC), and iSCSI storage.
- High Density: Delivering significant rack density, the PowerConnect 6248 is designed to give users the flexibility to maximize server and workstation connectivity in a 1U form factor. Up to 576 servers and/or clients can be connected in a stack of twelve 62xx series switches to provide the maximum density, flexibility, and manageability, and the stack is built on a 10/100/1000BASE-T Gigabit Ethernet switch.
- High Performance Stacking: The PowerConnect 6248 supports high performance stacking for up to twelve systems (each running at 48Gbps), which allows increased throughput to be added as needed without affecting network performance. With each switch supporting up to 184Gbps in switch capacity, the customer can have almost 3 Tbps of capacity in a single stack of 12 switches.
- Optional 10 Gigabit Ethernet: The PowerConnect 6248 switch supports up to four 10 Gigabit fiber & two 10GBase-T copper Ethernet uplinks for connectivity directly to 10GE servers routers, enterprise backbones and data centers.
- Advanced Layer 3 Capabilities: The PowerConnect 6248 supports advanced Layer 3 routing and multicast protocols to help reduce congestion and manage traffic in the network. Frequently used LAN routing protocols such as RIPv1/v2, OSPFv2/v3, VRRP, IGMP, DVMRP, PIM and LLDP-MED, are also supported.
- Advanced QoS: The PowerConnect 6248 offers flexibility in Quality of Service (QoS) by giving network administrators the ability to prioritize time-critical network traffic based on a variety of user-defined criteria. Administrators can expedite traffic based on L2 or L3 information, such as IP QoS, and provide greater control over traffic flow within the network. Voice VLANs are provided specifically for VoIP applications.
-
- Advanced Security: Access Control Lists (ACLs) can be supported on the switch, allowing the user to perform deep packet inspection. 802.1x port authentication offers both single and multiple host access. Further security is provided through Denial of Service (DoS) Attack Prevention, whereby the switch can help protect against common network attacks and CPU attacks.
- IPv6 Certified: IPv6 is version six of the "Internet Protocol" that has been in development for over 20 years. IPv6 has been designed to address IP address limitations of previous version of the Internet Protocol, enabling an increased number of unique IP addresses for broader scalability worldwide now and in the future.
