Features; Controller Versions - Fujitsu RAID 0/1 SAS based on LSI MegaRAID User Manual

Modular RAID 12Gb/s (SAS3.0)
5.2.1

Features

The RAID controller "PRAID EM400i " implements the LSI SAS3108 which is an
integrated SAS and I/O controller with dual embedded Power PC 476 cores
running at speeds up to 1.2 GHz. The LSI SAS3108 also provides the following
functionalities:
Provides an 8-lane 8.0 Gbit PCIe 3.0 host bus.
●
Provides an 8-port 12Gb/s SAS3 and 6Gb/s SATA3 interface.
●
Provides a 40-bit or a 72-bit 1866-MHz DDR3 SDRAM interface with a
●
hardware RAID assist engine for parity calculations.
Provides a full-featured hardware-based RAID solution that supports RAID
●
levels 0, 1, 5, 6, 10, 50, and 60.
2
Six I C interfaces used for Serial Boot strap ROM connection, memory
●
detection, PCI-E SMBus connectivity, battery / smart charger control, and
SAS sideband control.
Integrated dual UART for MegaRAID
●
Two banks of SGPIO signals to accompany the two sets of x4 SAS / SATA
●
ports.
16MB Flash
●
1kB Bootstrap EEPROM
●
Raid-key chip onboard
●
Onboard Flash for performing DDR3 SDRAM cache offload function to
●
protect data cache in case of host power failure.
