Notes:
• RAID 730-8i 1G Cache SAS/SATA adapter is not available for North America.
• RAID 530-8i SAS/SATA adapter cannot be mixed with RAID 730-8i 1G Cache
SAS/SATA adapter.
• RAID 730-8i 2G Flash SAS/SATA adapter cannot be mixed with RAID 730-8i 1G
Cache SAS/ SATA adapter or RAID 930-8i SAS/SATA adapter.
• The RAID 940 adapters can be mixed with the ThinkSystem 440-8i SAS/SATA
PCIe Gen4 12Gb HBA and the ThinkSystem 440-16i SAS/SATA PCIe Gen4 12Gb
HBA.
• Mixing of RAID/HBA 430/530/730/930 adapters (Gen 3) and RAID/HBA 440/940
adapters (Gen 4) in the same system is not allowed.
• RAID 930/940 series or 9350 series adapters require a RAID flash power module.
• RAID 5350/9350 series adapters cannot be mixed with HBA/RAID 430/440/530/
730/930/940 series SAS/SATA adapters.
• One processor: three system fans (including one redundant fan)
• Two processors: four system fans (including one redundant fan)
Note: If your server comes with only one processor, three system fans (fan 1 to fan
3) are adequate to provide proper cooling. However, you must keep the locations for
fan 4 occupied by a fan filler to ensure proper airflow.
