Hardware and Software Specifications

OS Drive Partitions

Table 1 lists the recommended OS drive partitions.

**Table 1** Drive space plan
Partition	Description	Size	Boot Flag
/boot	Boot partition	500 MB	on
/var	Partition for storing data generated during software running, such as logs and caches	> 300 GB	off
/var/lib/docker	Partition for storing Docker images and containers NOTE: Docker images and containers are stored in the /var/lib/docker partition by default. If the usage of the /var/lib/docker partition is greater than 85%, Kubernetes automatically triggers the resource eviction mechanism. Ensure that the usage of the /var/lib/docker partition is less than 85%.	> 300 GB	off
/etc/mindx-dl	Partition for storing imported certificates and KubeConfig files. Adjust the partition as required, and 100 MB is recommended.	100 MB	off
/	Primary partition	> 300 GB	off

Hardware Specifications

The hardware resources must meet the following requirements.

**Table 2** Resource requirements
Resource	Requirements
CPU	Management node CPU > 32 cores
Memory	Management node memory > 64 GB
Drive space	> 1 TB For details about the drive space plan, see Table 1.
Network	Out-of-band management (BMC): ≥ 1 Gbit/s In-band management (SSH): ≥ 1 Gbit/s Service plane: ≥ 10 Gbit/s Storage plane: ≥ 25 Gbit/s Parameter plane: 100 Gbit/s or 200 Gbit/s

Resource Configuration Requirements of Cluster Scheduling Components

The resource configuration of cluster scheduling components must meet the following requirements.

**Table 3** Component resource configuration requirements on the management node
Component	< 100 Nodes		< 500 Nodes		< 1000 Nodes
Component	CPU (Core)	Memory Size (GB)	CPU (Core)	Memory Size (GB)	CPU (Core)	Memory Size (GB)
Volcano Scheduler	2.5	2.5	4	5	5.5	8
Volcano Controller	2	2.5	2	3	2.5	4
Ascend Operator	2	2.5	2	3	2.5	4
ClusterD	1	1	2	2	4	8

**Table 4** Component resource configuration requirements on the compute node
Component	CPU (Core)	Memory Size (GB)
Ascend Device Plugin	0.5	0.5
NodeD	0.5	0.3
NPU Exporter	1	1
Ascend Docker Runtime	Docker service plugin, which does not require separate CPU resources and memory space.
