3 Abstract This white paper provides an overview of the second generation Gigabit Ethernet (GbE2) Interconnect Kit options for the ProLiant BL p-Class system. Each GbE2 Interc onnec t Kit includes a pair of industry- standard Ethernet switches that dramatically reduce the number of E thernet network cables attached to the rear of the ProLiant BL p-[...]

4 GbE2 Interconnect Kit The GbE2 Interconnect Kit contains two redundant, hot-swappable GbE2 Interconnect Switches and two 4-port LAN interconnect modules. Users first insert the LAN interconnect modules into the bottom- left and bottom-right interconnect bays at the rear of the server blade enclosure and then install the interconnect switches into[...]

5 redundant fans and they are powered by two independent feeds via the redundant, N+N hot-plug ProLiant BL p-Class power enclosure. Users can independently disable or enable the switch ports as desired. Auto-MDI/MDIX with auto- negotiation of speed and duplex mode is supported. Each GbE2 Interconnect S witch includes the following Ethernet ports: ?[...]

6 LAN in tercon nec t mod ule u plin k po rts The LAN int erconnect module uplink ports are typically us ed to connect the inte rconnect switches to the network infrastructure; however, they are standard Ethernet switch ports and may be used as desired. The GbE2 interconnect kits are identic al with exception of the LAN interconnect modules. The C-[...]

7 module that contain a 10-Gb Ethernet high-bandwidth uplink. The 10-Gb LAN interconnect modules may also contain Gigabit Ethernet ports, if space permit s. With these future planned options for the GbE2 Intercon nect Switch, an administrator will be able to independently select the switching layer as well as the uplink bandwidth, all within a sing[...]

8 Applications that utilize a single uplink port include testing and ev aluation systems, server blade enclosures with a few installed servers, and applications that require minimal band width. On a heavily utilized system, using a single uplink port for all 32 network adapters can cause a traffic bottleneck. For example, u sing one uplink from int[...]

9 Fibre Chann el pass-through The GbE2 Interconnect Kits offer the ability to pass-through BL20p G2 Fibre Channel signals using the optional GbE2 Storage Connectivity Kit. Therefore, both Ethernet LAN signal consolidation and Fibre Channel SAN signal pass-through is now possible with a single interconnect. The GbE2 Interconnect Switch chassis is si[...]

10 Figure 5. BL20p G2 Fibre Channel signal routing with the GbE2 Interconnect Swit c h With the GbE2 Storage Connectivity Kit installed, both Fibre Channel SAN and Ethernet LAN signals exit the rear of the server blade enclosure, each type of signal on its dedicated interconnect module (Figure 6). Just like the LAN QuadT2 and QuadSX interc onnect m[...]

11 Switch management The GbE2 Interconnect Switch is an industry-standard managed Ethernet switch, which means that users configure and manage the switch like other industry-standard Ethernet switches. To aid users during initial deployment, the GbE 2 Interconnect Switch includes a default configuration that is ful ly operational at initial boot an[...]

12 configuration file. The confi guration file has a text-based format, which allows it to be directly viewed, printed, and edited. E ach GbE2 Inte rconnect Switch has thre e configuration s ettings in memory (active, back-up, and fac to ry); any one o f these settings can be selected as the cu r rent runtime version . Users can perform firmware op[...]

13 Script able co mman d line int erface The CLI provides the added benefits of scripting, a set-up utility and other enhanced switch management tas ks, an out-of-band connection, and more. T he main menu opens aft er a successful log- in (Figure 9). This interface may be accessed locally via the front panel RS-232 console po rt o n eac h interconn[...]

Additional switch se curity meas ures include: ?[...]

15 The optional HP Diagnostic Station (Figure 11) is available to configure and diagnose an interconnect switch or a server blade that has been removed from the server blade enclosure. The Diagnostic Station provides power to the interconnect switch and can be used to perform any of the following tasks: • Build the initial interconnect switch con[...]

16 • The ability to set the interconnect switch to a v alid firmware image in case of firmware corruption.

17 • Network Fault Tolerance (NFT) • Transmit Load Balancing (TLB) • Switch-assisted Load Balanc ing (SLB) When teaming HP NC series network adapters with the interconnect switch, NFT and TLB teaming are the same as with any ProLiant system. However, for SLB teaming, the pre-defined switch-to-server architecture across the server blade enclos[...]
