Chapter 3: Maintenance and Component Installation
3.4 Chassis Components
This section provides instructions on installing and replacing system components. To assure
compatibility, only use components that match the specifications or part numbers given.
Storage Drives
The 2029U-TN24R4T supports twenty-four NVMe 2.5" hot-swap storage drives. Four drive
bays are hybrid that can support SAS3 with an optional add-on card. In addition, there are
two SATA 2.5" drive bays in the rear, and two internal M.2 (1 SATA, 1 NVMe slots).
The server can be purchased with drives installed or without drives installed.
For VROC configurations, refer to the VROC appendix in this manual.
Note:
Enterprise level hard disk drives are recommended for use in Supermicro chassis and
servers. For information on recommended HDDs, visit the Supermicro website at
https://www.
supermicro.com/products/nfo/Ultra.cfm.
The external drives are mounted in drive carriers that simplify their removal from the chassis.
These carriers also help promote proper airflow. Even carriers without drives must remain in
the chassis for proper airflow.
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.
