3.6 Chassis Components
Storage Drives
The 227GTS chassis supports up to four 2.5" storage drives (two drives per node) in drive
carriers to simplify their removal from the chassis. These carriers also help promote proper
airflow. Note that only SSDs are supported, spindle-type HDDs are not.
All four drive carriers reside in a storage module that has Slim-SAS connectors at the rear
where the data cables attach to the motherboard. A rear power connector is also used to
provide input power to the module backplane from the motherboard. This design enables a
true hybrid solution with any slot able to support NVMe U.2, SATA or SAS with optional HBA.
Note:
Enterprise level hard disk drives are recommended for use in Supermicro chassis and
servers.
Drive Carrier Indicators
Each drive carrier has two LED indicators: an activity indicator and a status indicator. For
RAID configurations using a controller, the meaning of the status indicator is described in
the table below. For OS RAID or non-RAID configurations, some LED indications are not
supported, such as hot spare.
