Integrated disk drives
Describes disk drives that are integrated into the server chassis of the ECS Appliance.
D-Series
In D-Series servers, OS disks are integrated into the server chassis and are accessible
from the front of the server chassis. Each node has one OS SSD drive.
U-Series
In U-Series servers, OS disks are integrated into the server chassis and are accessible
from the front of the server chassis. Each node has one OS SSD drive.
Early Gen1 appliances had two mirrored disks per node.
C-Series
In C-Series servers with integrated storage disks, the disks are accessible from the
front of the server chassis. The disks are assigned equally to the four nodes in the
chassis. All disks must be the same size and speed. Gen1 uses 6 TB disks and Gen2
uses 8 TB and 12 TB disks.
In Gen1 only, the first integrated disk that is assigned to each node is called disk drive
zero (HDD0). These storage drives contain some system data.
