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.
For some storage controllers, you can order a power fail safeguard module to prevent data loss from
power outages. This module provides a flash card and a supercapacitor. When a system power
failure occurs, the supercapacitor provides power for a minimum of 20 seconds. During this interval,
the storage controller can transfer data from DDR memory to the flash card, where the data remains
indefinitely or until the controller retrieves the data. If the storage controller contains a built-in flash
card, you can order only a supercapacitor.
