The PowerConnect™ 5448 le brinda a los clientes importantes beneficios en cuanto a la relación precio/rendimiento. Además de ofrecer una plataforma de red segura y de alto rendimiento y de brindar características avanzadas de administración de red, el PowerConnect 5448 es el primer conmutador del mundo en autooptimizarse para el tráfico de almacenamiento iSCSI. Estas características les permiten a los administradores de red optimizar y proteger efectivamente su tráfico de red.
PerformanceThe PowerConnect 5448 delivers 48 ports of wire-speed Gigabit Ethernet with advanced security and enterprise management features to meet the needs of organizations of all sizes. Providing 96 Gbps for switching capacity and 71.2 Mbps forwarding rate, the PowerConnect provides ample performance for server aggregation, wiring closets and iSCSI storage. Combo ports — four ports of either small form-factor pluggable (SFP) Fiber support or 10/100/1000 Copper support — provide for connectivity flexibility and long-haul connections.
iSCSI OptimizationThe PowerConnect 5400-series is the world’s first switch portfolio to automatically optimize itself for iSCSI storage. The switches automatically detect whether traffic flows are iSCSI-based and, if so, assigns that traffic flow a high-level quality of service. This helps ensure that iSCSI storage traffic is prioritized in the event of resource contention. The 5400-series also provides information about all active iSCSI sessions to allow for easier management and optimization.
SecurityThe PowerConnect 5448 offers multiple options and levels of security. Industry-standard features include Secure Shell (SSH)/Secure Sockets Layer (SSL) management encryptions, Dynamic Host Configuration Protocol (DHCP) snooping, IP- and Media Access Control (MAC)-based access control lists (ACLs) access password protection, and port-based MAC address alert and lockdown. Higher level security is provided through Remote Authentication Dial-In User Service (RADIUS) for switch management access, 802.1x authentication and Terminal Access Controller Access-Control System Plus (TACACS+), and management access filtering using management access profiles.
Quality of ServiceThe PowerConnect 5448 Ethernet switch supports open industry standards, including quality of service (L3-aware), multicast support, link aggregation and dynamic virtual LAN (VLAN) configurations.
Voice over IP (VoIP) Functionality
Voice-VLAN functionality helps ensure VoIP traffic is prioritized in the event of resource contention. Link Layer Discovery Protocol-Media Endpoint Discovery (LLDP-MED) provides detailed network topology information, emergency call service using IP phone location information and troubleshooting information.
ManagementPowerConnect provides numerous management options, including an industry-standard command line interface (CLI), remote management using an embedded Web server and support for Simple Network Management Protocol (SNMP)-based management applications.
