configuration is designed to allow for continued network access to each server blade in case of a component or link failure. The switch redundancy and failover features include: • Up to eight separate switches per one HP c-Class BladeSystem server blade enclosure • Five Gigabit Ethernet uplink - HP GbE2c | HP GbE2c Ethernet Blade Switch for c-Class BladeSystem User Guide - Page 9
guide on the HP website (http://www.hp.com/go/bladesystem/documentation). Dual switches In a dual switch configuration, two switches in the server blade enclosure provide switch redundancy and redundant paths to the network ports on the server blades. Each switch has five external Gigabit Ethernet - HP GbE2c | HP GbE2c Ethernet Blade Switch for c-Class BladeSystem User Guide - Page 10
system, using a single uplink port for 32 Ethernet signals causes a traffic bottleneck. For optimum performance, HP recommends using at least one uplink port per switch. Supported technologies Layer 2 switching The switch uses Gigabit Layer 2 switching technology. Layer 2 refers to the Data Link - HP GbE2c | HP GbE2c Ethernet Blade Switch for c-Class BladeSystem User Guide - Page 11
remaining links in the group. TFTP support TFTP support allows the switch firmware to be upgraded by downloading a new firmware file from a TFTP server to the switch. Firmware images of the switch are also uploaded to a TFTP server, a configuration file is downloaded into a switch from a TFTP server - HP GbE2c | HP GbE2c Ethernet Blade Switch for c-Class BladeSystem User Guide - Page 12
configurable from the browser-based interface, but because the connection is based on an IP address for these interfaces, users will have to reconnect with the newly assigned IP address. NTP The switch maintains the current date and time. This information displays on the management interfaces and - HP GbE2c | HP GbE2c Ethernet Blade Switch for c-Class BladeSystem User Guide - Page 13
supports jumbo frames up to 9216 bytes, which help reduce server CPU utilization and increase application throughput. No configuration is required. The switch does not fragment frames as they exit, or assemble packets into jumbo frames as they enter the switch.
