HP 5900AF-48XG-4QSFP+ SWITCH CPNT .
Overview
The HP 5900 Switch Series is a family of high-density, ultra-low latency, top-of-rack (ToR) switches. It is part of the HP FlexFabric solution of the HP FlexNetwork architecture. Ideally suited for deployment at the server access layer of large enterprise data centers, the 5900 Switch Series is also designed for deployment at the data center core layer of medium-sized enterprises. With the increase in virtualized applications and server-to-server traffic, customers now require ToR switch innovations that will meet their needs for higher-performance server connectivity, convergence of Ethernet and storage traffic, the capability to handle virtual environments, and ultra-low latency all in a single device.
Features
Quality of Service (QoS)
⁍ Powerful QoS features: Flexible classification: Create traffic classes based on access control lists (ACLs), IEEE 802.1p precedence, IP, and DSCP or Type of Service (ToS) precedence; supports filter, redirect, mirror, remark and logging. Supports the following features: Strict Priority Queuing (SP), Weighted Fair Queuing (WFQ), Weighted Deficit Round Robin(WDRR), SP+WDRR together, configurable buffers, Explicit Congestion Notification (ECN) and Weighted Random Early Detection (WRED).
Data center optimized
⁍ Flexible 10 GbE high port density: the 5900 Switch Series enables customers to scale their server-edge 10 GbE ToR deployments to new heights with high-density 48 x 10GbE SFP+ ports delivered in a 1RU design; the high server port density is backed by 4 x 40GbE QSFP+ uplinks to deliver availability of needed bandwidth for demanding applications; the switch can also be configured as a 64 x 10 GbE port device by using a 40G-to-10 GbE splitter cable that turns each QSFP+ port into four 10-GbE ports
Manageability
⁍ Full-featured console: provides complete control of the switch with a familiar CLI
Resiliency and high availability
⁍ Intelligent Resilient Framework (IRF): HP IRF technology enables an HP FlexFabric to deliver resilient, scalable, and secured data center networks for physical and virtualized environments; up to four 5900 switches can be grouped together in an IRF configuration, which allows them to be configured and managed as a single switch with a single IP address; this simplifies ToR deployment and management, reducing data center deployment and operating expenses
Layer 2 switching
⁍ MAC-based VLAN: provides granular control and security; uses RADIUS to map a MAC address/user to specific VLANs
Layer 3 services
⁍ Address Resolution Protocol (ARP): determines the MAC address of another IP host in the same subnet; supports static ARPs; gratuitous ARP allows detection of duplicate IP addresses; proxy ARP allows normal ARP operation between subnets or when subnets are separated by a Layer 2 network
Layer 3 routing
⁍ Virtual Router Redundancy Protocol (VRRP) and VRRP Extended: allow quick failover of router ports
