TX100 S3 Operating Manual 17
Functional overview
I For more information on configuring the controller, see section
"Configuring the SAS/SATA RAID controller" on page 60.
Further information on SAS/SATA RAID controllers is provided in the
"Modular RAID Controller Installation Guide" (on ServerView Suite
DVD 2 under Industry Standard Servers - Expansion Cards - Storage Adapters
- LSI RAID / SCSI Controllers).
Further information on other SAS/SATA RAID controllers (e.g. for
operating external SAS/SATA hard disk drives or tape drives) is available
on ServerView Suite DVD 2 under Industry Standard Servers - Expansion
Cards - Storage Adapters - LSI RAID / SCSI Controllers.
Accessible drives
The first (top) bay contains the server's DVD drive.
The 5.25-inch bay below is available for one additional accessible drive
(CD/DVD drives or a magnetic tape drive).
The accessible drives cannot be replaced during operation.
Power supply
The server has a permanently installed power supply unit that adjusts
automatically to any mains voltage in the range 100 V - 240 V. There are two
different types:
– a power supply unit with up to 85% efficiency
– a power supply unit with up to 94% energy efficiency and 0-Watt functionality
High level of availability and data security
When memory data is accessed, 1-bit errors are identified in the main memory
and automatically corrected with the error correcting code (ECC) method.
ASR&R (Automatic Server Reconfiguration and Restart) restarts the system in
the event of an error and automatically "hides" the defective system
components.
The PDA (Prefailure Detection and Analysis) technology from Fujitsu analyzes
and monitors all components that are critical for system reliability.
A RAID controller supports different RAID levels and increase the availability
and data security of the system.
