For more information on configuring the controller, see section
"Configuring the SAS/SATA RAID controller" on page
Further information on SAS/SATA RAID controllers is provided in the
"Modular RAID Controller Installation Guide" (on the Fujitsu manuals
server under x86 Servers - Expansion Cards - Storage Adapters - LSI SAS /
SCSI RAID 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 the Fujitsu manuals server under x86 Servers - Expansion Cards -
Storage Adapters - LSI SAS / SCSI RAID Controllers.
USB connectors
The two USB 3.0 connectors of the server node support activities carried out by
the service technician. The maximum length of the external cable are three
meters.
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.
A RAID controller supports different RAID levels and increase the availability
and data security of the system.
The hot-plug HDD modules provide additional availability.
iRMC S4 with integrated management LAN connector
The iRMC S4 (integrated Remote Management Controller) is a Baseboard
Management Controller (BMC) with integrated management LAN connector
and expanded functionality that was previously only available with additional
plug-in cards. In this way, the iRMC S4 enables complete control of PRIMERGY
servers, regardless of system status, and thus particularly the control of
PRIMERGY servers that are in the "out-of-band" system status.
Major functions supported by the iRMC S4 include the following:
Browser access via iRMC S4´s own Web server
●
Secure communication (SSH, SSL)
●
Power Management for the managed server (depending on its system
●
