Introduction
Features
Hard Disk Drives
Each server blade can accommodate two 2.5-inch IDE hard disk drives (HDD)
with 20, 40, 60 or 80 GB. The maximum hard disk capacity on one server blade
is 160 (2x80) GB in a RAID 0 configuration. Usually two disks are mirrored in a
RAID 1 configuration. On-board IDE-RAID controller is standard.
LAN Availability
Each server blade has two Gigabit LAN channels. Each of the four switch blades
has 10 Gigabit downlink and three uplink ports for 10/100/1000 Base TX.
Power Supply
Two hot-swappable power supply units which adjust automatically to any power
voltage in the range 100 V - 127V or 200 V - 240 V in a redundant power supply
configuration ensure enough power for the system. If one of these units fails, the
second one ensures that operation continues unimpaired. The defective power
supply unit can be replaced during operation (hot-swap).
Ventilation
The system is kept cool by three fans in each power supply unit and five fans in
the front panel in a redundant and hot-swappable configuration with the two rear
fans.
Make sure that the system is always populated with two power supply
units.
High Level of Availability and Failure Protection
When memory data is accessed, 1-bit errors in the main memory are recog-
nized and automatically corrected with the ECC (Error Correcting Code)
method.
ASR&R (Automatic Server Reconfiguration and Restart) restarts the system in
the case of an error and automatically “hides” the defective system components.
The PDA (Prefailure Detection and Analyzing) technology from Fujitsu Siemens
Computers analyzes and monitors all components relevant for system reliability.
The on-board IDE-RAID controllers support RAID Levels 0 and 1 and increase
system availability.
