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 HDDs 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 on the Y-cable 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.
