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 Layer 2/3 Ethernet Blade Switch for c-Class BladeSystem User - 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 Layer 2/3 Ethernet Blade Switch for c-Class BladeSystem User - 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 Layer 2/3 Ethernet Blade Switch for c-Class BladeSystem User - Page 11
, the greater the switch CPU utilization. For maximum switch performance, HP recommends being judicious when configuring the number of VLANs. NOTE: VLAN 4095 is reserved for future functionality. Spanning Tree Protocol The switch supports IEEE 802.1D STP, which allows the blocking of links that form - HP GbE2c | HP GbE2c Layer 2/3 Ethernet Blade Switch for c-Class BladeSystem User - Page 12
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 Layer 2/3 Ethernet Blade Switch for c-Class BladeSystem User - Page 13
network to execute management commands. SCP is used to copy files securely from one machine to another. SCP uses SSH for encryption of data on the network. On a switch, SCP is used to download and upload the switch configuration via secure channels. XModem The switch supports XModem for transferring - HP GbE2c | HP GbE2c Layer 2/3 Ethernet Blade Switch for c-Class BladeSystem User - Page 14
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.
