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.
4 GbE2 Interconnect Kit The GbE2 Interconnect Kit contains two redundant, hot-swappable GbE2 Interconnect Switches and two 4-port LAN interconnect modules.
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.
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.
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.
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.
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.
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).
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.
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 .
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.
14 • Specify the IP-based management networks that are allowed to access each switch. • Set a user interface idle time-out period and disable web-based and Telnet access. • Enable a secure shell (SSH) session to the C LI interfac e. • Modify default Telnet and HTTP server socket port numbers.
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.
16 • The ability to set the interconnect switch to a v alid firmware image in case of firmware corruption. For more detailed information on the administration ca pabilities of the ProLiant BL p-Class GbE2 Interconnect Sw itch, see the ProLiant BL p- Class GbE2 Interconnect Switch user g uides.
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.

Un punto importante, dopo l’acquisto del dispositivo (o anche prima di acquisto) è quello di leggere il manuale. Dobbiamo farlo per diversi motivi semplici:
Se non hai ancora comprato il HP (Hewlett-Packard) GbE2 è un buon momento per familiarizzare con i dati di base del prodotto. Prime consultare le pagine iniziali del manuale d’uso, che si trova al di sopra. Dovresti trovare lì i dati tecnici più importanti del HP (Hewlett-Packard) GbE2 - in questo modo è possibile verificare se l’apparecchio soddisfa le tue esigenze. Esplorando le pagine segenti del manuali d’uso HP (Hewlett-Packard) GbE2 imparerai tutte le caratteristiche del prodotto e le informazioni sul suo funzionamento. Le informazioni sul HP (Hewlett-Packard) GbE2 ti aiuteranno sicuramente a prendere una decisione relativa all’acquisto.
In una situazione in cui hai già il HP (Hewlett-Packard) GbE2, ma non hai ancora letto il manuale d’uso, dovresti farlo per le ragioni sopra descritte. Saprai quindi se hai correttamente usato le funzioni disponibili, e se hai commesso errori che possono ridurre la durata di vita del HP (Hewlett-Packard) GbE2.
Tuttavia, uno dei ruoli più importanti per l’utente svolti dal manuale d’uso è quello di aiutare a risolvere i problemi con il HP (Hewlett-Packard) GbE2. Quasi sempre, ci troverai Troubleshooting, cioè i guasti più frequenti e malfunzionamenti del dispositivo HP (Hewlett-Packard) GbE2 insieme con le istruzioni su come risolverli. Anche se non si riesci a risolvere il problema, il manuale d’uso ti mostrerà il percorso di ulteriori procedimenti – il contatto con il centro servizio clienti o il servizio più vicino.
