Controllers For Internal Storage - Lenovo ThinkServer sd350 Product Manual

Controllers for internal storage

The onboard SATA controller in the sd350 (integrated into the Intel C612 chipset) implements Intel Rapid
Storage Technology enterprise (RSTe) and supports SATA drives installed in the 6 drive bays. The onboard
controller supports a minimum of 1 drive and a maximum of 6 drives.
Configuration notes with the onboard SATA controller:
Only SATA drives are supported
Up to 6 drives are supported
The controller supports RAID (RAID 0, 1, 5, 10), however only 4 drives can be configured in a RAID
array. The remaining 2 drives must be configured non-RAID (JBOD).
The onboard SATA controller, when RAID mode (Intel RSTe) is enabled, is not supported by
virtualization hypervisors, including VMware ESXi, Linux KVM, Xen, and Microsoft Hyper-V. Non-
RAID mode (AHCI mode) is supported by virtualization hypervisors.
Alternatively, the sd350 also supports an H701-L RAID adapter (RAID 0, 1, 10) installed in a dedicated
mezzanine slot in the sd350. The H701-L RAID adatper supports a minimum of 2 drives and a maximum of
6 drives. The following figure shows the H701-L adapter (with the attached air baffle removed).
Second processor required: The use of the H701-L RAID adapter requires the second processor be
installed.
