Chapter 6. U.2 NVMe Cache Drive
Upgrade from 4 to 8
If you require more drive cache capacity, you can increase the cache by adding four more NVMe drives
to the DGX A100 system.
Important: Upgrade using only U.2 NVMe drives of the same density (capacity) as the existing four
drives.
6.1. U.2 NVMe Cache Drive Upgrade Overview
This is a high-level overview of the steps needed to upgrade the DGX A100 system’s cache size.
1. Identify the density (capacity) of the currently installed NVMe drives.
2. Place an order for additional four NVME drives from NVIDIA Sales.
3. Power o the system.
4. Remove the air baes in the blank drive slots.
5. Install the NVMe drives in the DGX A100 system.
6. Power on the system.
7. Re-initialize the ∕raid lesystem to recognize all eight drives.
8. Conrm the system is healthy by running nvsm show health.
6.2. Determining the NVMe Drive to Order
1. Identify the drives in the RAID volume by issuing the following.
$ sudo nvme list
2. Determine the drive size (3.84 TB or 7.68 TB) of the currently installed drives, and order drives of
same density (capacity) from the NVIDIA Sales team.
