Re: What is the minimum or optimal configuration specifications of each DSX local node?

Explorer

This really depends on which type of DSX Local deployment you are going for. There are two different types of DSX Local configurations available:

  • Nine node configuration
  • Three node configuration

Requirements for a Nine node configuration:

Node Type Number of Servers (BM/VM) CPU RAM Disk partitions
Control Plane 3 8 cores 16 GB Minimum 500 GB with XFS format for installer files partition
Storage 3 16 cores 32 GB Minimum 500 GB with XFS format for installer files partition + minimum 500 GB with XFS format for data storage partition
Compute 3 32 cores 64 GB Minimum 500 GB with XFS format for installer file partition

Requirements for a Three node configuration:

Node Type Number of Servers (BM/VM) CPU RAM Disk partition
Control Plane/Storage/Compute 3 32 cores 64 GB Minimum 500 GB with XFS format for installer files partition + minimum 500 GB with XFS format for data storage partition

Disk Requirements

Ensure that the storage has good disk I/O performance.

Disk latency test: dd if=/dev/zero of=/root/testfile bs=512 count=1000 oflag=dsync The value should be better or comparable to: 512000 bytes (512 kB) copied, 1.7917 s, 286 kB/s

Disk throughput test: dd if=/dev/zero of=/root/testfile bs=1G count=1 oflag=dsync The value should be better or comparable to: 1073741824 bytes (1.1 GB) copied, 5.14444 s, 209 MB/s
