Server configurations

This topic describes the hardware and software configuration requirements of servers, including the operating system, BIOS settings, disk mounting, and NIC settings.

Operating system

The following table describes the Linux operating systems that support OceanBase Database.

BIOS settings

Special settings:

• Disable non-uniform memory access (NUMA) for Intel.

• Enable NUMA for Hygon, AMD, Kunpeng, and Arm.

You must disable the following BIOS options:

• C-State

• P-State

• EIST

• Power saving

• Turbo mode

The following options must be configured or enabled for BIOS:

• Automatic Power on After Power Loss: Always on

• Intel Virtualization Technology: Enable

• SOL Console Redirection: Enable

• Hyper-Threading: Enable

• Hardware Perfetcher: Enable

• VT-d: Enable

• SR-IOV: Enable

• Energy/Performance Bias: Maximum Performance

Disk mounting

• The following table lists the disk mounting points of an OceanBase Cloud Platform (OCP) server.

  Mounting point	Size	Description	Disk format
  /home	100 GB to 300 GB	The operation log disk of the components.	Ext4 is recommended.
  /data/log1	3 to 4 times the memory size	The log disk of the OCP MetaDB.	Ext4 is recommended.
  /data/1	Depends on the size of data to be stored	The data disk of the OCP MetaDB.	Ext4 is recommended. If the size of the data disk is greater than 16 TB, XFS is recommended.
  /docker	200 GB to 500 GB	The Docker root directory.	Ext4 is recommended.

• The following table lists the disk mounting points of an OBServer.

  Mounting point	Size	Description	File system format
  /home	100 GB to 300 GB	The operation log disk of the OBServer.	Ext4 is recommended.
  /data/log1	3 to 4 times the memory size	The log disk of OBServer.	Ext4 is recommended.
  /data/1	Depends on the size of data to be stored	The data disk of the OBServer.	Ext4 is recommended. If the size of the data disk is greater than 16 TB, XFS is recommended.

• The following table lists the disk mounting points of an OceanBase Migration Service (OMS) server.

  Mounting point	Size	Description	File system format
  /data/oms	400 GB. The disk size depends on the size of the objects to be synchronized, the number of synchronization tasks, the frequency of DML operations on the synchronization objects, and the retention period of stores.	The data disk for OMS stores.	Ext4 is recommended.

lvcreate -n data -L 3000G obvg --stripes=3 --stripesize=128

NIC settings

It is recommended that you configure two 10GE NICs.

• You can name the bond mode as bond0, mode1, or mode4. mode4 is recommended. If you use mode4, you must configure 802.3ad for the vSwitch.
• It is recommended that you name the NICs as eth0 and eth1.
• It is recommended that you use the network service instead of NetworkManager.

Other software requirements

Docker must be installed on servers where OceanBase Admin Toolkit (OAT), OceanBase Developer Center (ODC), and OMS are deployed. The following table lists the version requirements of Docker.
