Availability and serviceability

The BladeCenter H chassis provides many features to simplify serviceability and increase system uptime:

• BladeCenter reduces the number of parts that are required to run the system. Sharing fans, power supplies, systems management, and ports means that there are fewer parts to buy and maintain, and fewer components that can fail and cause downtime.
• Hot-swap components, such as the server, switches, power supplies, and blowers, ensure maximum uptime.
• Redundant components, such as blowers and power supplies, ensure that systems can remain available even during hardware maintenance windows and failures.
• The Predictive Failure Analysis (PFA) detects when system components operate outside of standard thresholds and generates proactive alerts in advance of possible failure, therefore increasing uptime.
• Dual independent power and signal connectors to the BladeCenter H chassis midplane provide fault tolerance to increase uptime.
• The light path diagnostics panel and individual light path LEDs quickly lead the technician to failed (or failing) components. These features simplify servicing, speed up problem resolution, and improves system availability.
• A 3-year customer replaceable unit and onsite limited warranty and next business day 9x5 provides an additional peace of mind.

Energy efficiency

The BladeCenter H chassis offers the following energy-efficient features to save energy, reduce operational costs, increase energy availability, and contribute to a green environment:

• The energy-efficient components and component-sharing design of the BladeCenter chassis provides ultimate power and cooling savings.
• BladeCenter H helps reduce energy costs with leadership high-efficiency power supplies that are 94% efficient and 80 PLUS Platinum Certified.

The BladeCenter H chassis provides connection paths between the server blade bays and I/O bays through a hardwired dual redundant midplane.

The BladeCenter H chassis has two types of fabrics inside:

• Standard fabric (I/O bays 1, 2, 3, and 4)
• High-speed fabric (I/O bays 7, 8, 9, and 10)

The BladeCenter H chassis has a total of 10 I/O bays. Each blade bay has a total of eight dedicated connection paths to the I/O modules, as shown in the following figure.

Figure 4. BladeCenter H I/O topology

The bays are:

• Bays 1 and 2 support only standard Ethernet-compatible I/O modules. These bays are routed internally to the onboard Ethernet controllers on the blades.
• Bays 3 and 4 can be used either for standard switch or pass-through modules (such as 8 Gb Fibre Channel or Gigabit Ethernet modules) or for bridge modules. These bays are routed internally to the CIOv connector on the blades.
• Bays 5 and 6 are dedicated for bridge modules only and do not directly connect to the blade bays. Bridge modules provide links to the I/O bays 7 - 10 and can be used as additional outputs for I/O modules in those bays. If I/O bays 3 and 4 are used for bridge modules, they are not directly connected to the blades, and bay 3 provides redundancy for bay 5, and bay 4 provides redundancy for bay 6.
• I/O bays 7 - 10 are used for high-speed switch modules such as the Virtual Fabric 10 Gb Switch Module or Cisco Nexus 4001I Switch Module. These bays are routed internally through midplane connectors to the ports on CFFh expansion cards (with HS23 blade, I/O bays 7 and 9 are routed to the integrated 10GbE ports on HS23 through LOM Interposer Card). I/O bays 7 - 10 can also be converted to the standard I/O bays with the Multi-Switch Interconnect Module (MSIM).

The I/O modules must be compatible with the I/O interfaces that are present in the blade servers. For example, when a Fibre Channel expansion card is installed in a blade server, I/O modules 3 and 4 must also be Fibre Channel-based (that is, an FC switch module), and vice versa. If you install FC switches in bays 3 and 4, then any expansion cards that are installed in all other blade servers in the same chassis must be Fibre Channel.

Table 4 shows the connections between the adapter slots in the compute nodes to the switch bays in the chassis.

Table 4. Adapter to I/O bay correspondence

Tables 5 through 7 list the I/O modules that are supported by the BladeCenter H chassis and the corresponding I/O bay into which the I/O module can be installed.
