A highly available and expandable,
TOE helps improve overall system performance by offloading TCP/IP protocol processing from the system microprocessor to the onboard Ethernet TOE processor.
The controllers also support highly secure remote power management using IPMI 2.0, plus Wake on LAN® and PXE (Preboot Execution Environment) flash interface. Optional PCI adapters offering failover and load balancing between adapters are available for added throughput and increased system availability.
Ultra-Efficient Cooling
Strategically located fans, combined with efficient airflow paths, provide highly effective system cooling for the x3650, known as Calibrated Vectored Cooling. The base server with one power supply includes five fans. Five additional
The system contains four cooling zones. Zone 1 (incorporating one fan in a nonredundant configuration or two with redundancy) cools one processor. Zone 2 (one or two fans) cools the other processor, Zone 3 (one or two fans) cools the adapter slots and memory, and Zone 4 (two or four fans) cools the HDDs, power supplies and system backplane. In addition, each power supply also contains a fan.
The fans automatically adjust speeds in response to changing thermal requirements, from a minimum of 4,250 RPMs to a maximum of 8,000 RPMs, depending on the zone, redundancy, and internal temperatures. When the temperature inside the server increases, the fans speed up to maintain the proper ambient temperature. When the temperature returns to a normal operating level, the fans return to their default speed. Why not simply run the fans at 100% capacity all the time? For several good reasons: to reduce the ambient noise, reduce the wear-
In addition, the server uses hexagonal ventilation holes in the chassis. Hexagonal holes can be grouped more densely than round holes, providing greater airflow through the system cover.
This cooling scheme is important because newer, more powerful processors generate a significant amount of heat, and heat must be controlled for the system to function properly.
Light Path Diagnostics
Light path diagnostics enables a technician to quickly identify and locate a failed or failing system component, such as a specific fan or memory DIMM. This enables quick replacement of the component, which helps increase server uptime and lower operating costs.
The front of the server has an LED indicator light to show possible component failures. If the front LED indicates an error condition, by pressing a button on the front of the server an LED panel will pop out and drop down for easy viewing without the need to open the server cover or remove the server from the rack. The light path diagnostics panel tells the servicer which component requires attention. In addition, many components have their own identifying LEDs. For example, each of the eight memory modules has an LED next to the socket, as do both processors, all adapter slots, all fans, all power supplies, the voltage regulator module and the service processor, allowing the servicer to easily identify exactly which component needs servicing. By following the “light path,” the component can be replaced quickly, and without guesswork. (Note: In the event of a failed DIMM, the system will restart and mark the DIMM as bad while offline, thus allowing the system to continue running, with reduced memory capacity, until serviced.)
