Info

The Brocade Enterprise SAN Module can be installed only in I/O module bays 3 or 4. If you install a 2-Port Fibre Channel Switch Module, any blade servers that have expansion cards must use a Fibre Channel expansion card. Use the Brocade Enterprise SAN Switch Module when you require maximum compatibility with external SAN fabrics constructed using Brocade-based switches. The Brocade Enterprise SAN Switch Module is functionality equivalent to the Brocade Silkworm 3900 SAN switch. Brocade Entry SAN Switch Module The Brocade Entry SAN Switch Module is almost identical to the Brocade Enterprise SAN Switch Module described earlier. However, it is limited to participating in SAN fabrics that contain at most two SAN switches. Optical Pass-thru Module The Optical Pass-thru Module provides the capability to access one of the network interfaces on each blade server via an externally accessible optical interface. You can use this optical interface to connect the blade servers to external switches that support compatible optical interfaces, including: ► LAN switches ► SAN switches ► Myrinet switches Each Optical Pass-thru Module has four multi-port optical connectors. The connectors are designed for special break-out cables that provide either four SC connectors (P/N 73P5992) or four LC connectors (P/N 73P6033) per multi-port optical connector. You can connect to a maximum of 14 blade server network interfaces using four of these cables (two of the connectors are unused on the fourth cable). The type of external switch that you connect to the Optical Pass-thru Module must be compatible with the network interface on the blade servers that are connected to the I/O module bay where the Optical Pass-thru Module is installed. If you install an Optical Pass-thru Module in I/O module bay 1 or 2, you must connect the optical interfaces to a Gigabit Ethernet switch with 1000Base-SX interfaces. Restriction: When a BladeCenter chassis contains a BladeCenter JS20, always use a LAN switch module in I/O module bay 1 to support the SoL remote text console function. This is because there is no other mechanism for providing a console on a BladeCenter JS20. 20 The IBM Eserver BladeCenter JS20
2.1.5 Blade servers If you install an Optical Pass-thru Module in I/O module bay 3 or 4, you must connect the optical interfaces to an external switch that is compatible with the type of expansion cards installed on blade servers. If you install a Myrinet expansion card on any blade server, you must install an Optical Pass-thru Module in I/O module bay 4 to enable the Myrinet interface on the expansion card to be connected to an external Myrinet switch. This is because currently no Myrinet switch modules are available for the BladeCenter. IBM offers a variety of blade servers that you can install in a BladeCenter chassis. ► IBM ^ BladeCenter JS20 Type 8842 Blade Server ► IBM ^ BladeCenter HS20 Type 8678 Blade Server ► IBM ^ BladeCenter HS20 Type 8832 Blade Server ► IBM ^ BladeCenter HS40 Type 8839 Blade Server Because the BladeCenter JS20 is the subject of this book, we describe it in greater detail in 2.2, “BladeCenter JS20” on page 22. The following sections briefly introduce the other blade servers. You can install any combination of blade servers in the same BladeCenter chassis subject to available power supply module capacity. HS20 Blade Server The HS20 Blade Server is a single-width blade server that contains either one or two Intel® Xeon DP processors and up to 8 GB of memory. Up to 14 HS20 Blade Servers can be installed in each BladeCenter chassis. The original HS20 Type 8678 Blade Server used a 400 MHz front side bus (FSB) and supports a range of processor speeds from 2.0 GHz to 2.8 GHz. The HS20 Type 8678 Blade Server is now withdrawn from marketing and has been replaced by the HS20 Type 8832 Blade Server. The HS20 Type 8832 Blade Server uses a 533 MHz FSB and supports a range of processor speeds from 2.4 Ghz to 3.2 GHz. HS40 Blade Server The HS40 Blade Server is a double-width blade server that contains from one to four Intel Xeon MP processors and up to 16 GB of memory. Up to seven HS40 Blade Servers can be installed in each BladeCenter chassis. Chapter 2. Hardware components 21
