NOTE:
300W*: Slots 11 through 14 on the rear 4GPU module support only GPU modules. To provide a
power capacity of 300 W, you must connect external GPU power cords.

Storage controllers

The server supports the following types of storage controllers:
Embedded VROC controller—Embedded in the server and does not require installation.
•
Standard storage controller—Comes in a standard PCIe form factor and typically requires a
•
riser card for installation.

Powerfail safeguard modules

For some storage controllers, you can order a powerfail safeguard module to prevent data loss when
power outage occurs.
A powerfail safeguard module provides a flash card and a supercapacitor. When a system power
failure occurs, this supercapacitor can provide power for a minimum of 20 seconds. During this
interval, the storage controller transfers data from DDR memory to the flash card, where the data
remains indefinitely or until the controller retrieves the data.
A supercapacitor has a lifespan of 3 to 5 years. If the lifespan of a supercapacitor expires, a
supercapacitor exception might occur. The system notifies users of supercapacitor exceptions by
using the following methods:
