Particionamento personalizado e RAID (CPR)

O Equinix Metal™ oferece um recurso de Particionamento e RAID Personalizados (CPR), que você especificar a configuração do disco ao você um servidor reservado.

Para usar o CPR, crie um objeto JSON que:

  • Indica quais discos você deseja formatar.
  • Como você quer que esses discos sejam formatados.
  • Qual sistema de arquivos deve ser criado nos discos.
  • Onde montar a partição depois de criada.

Use os exemplos para começar a criar o seu próprio.

Requisito de servidor reservado​

Um servidor reservado é necessário porque o esquema exato da unidade deve ser conhecido previamente para que a personalização funcione por meio da API. O recurso de Particionamento e RAID Personalizados não está disponível para instâncias sob demanda.

Provisionamento com RCP​

Para usar o CPR, você precisará implantar um servidor de suas reservas de hardware por meio da API. Quando você enviar sua solicitar POST para o endpoint projects/<id>/devices, você precisará enviar sua configuração CPR como um objeto JSON com o parâmetro storage no corpo da solicitar.

curl -X POST \
-H "Content-Type: application/json" \
-H "X-Auth-Token: <API_TOKEN>" \
"https://api.equinix.com/metal/v1/projects/{id}/devices" \
-d '{
  "hardware_reservation_id":"<reservation_id>",
  "hostname": "<your-hostname>",
  "plan": "<plan_slug>",
  "operating_system": "<os_slug>",
  "storage": "<CPR_JSON_definition>",
  }'

Exemplos por servidor​

c3.small.x86​

O c3.small.x86 vem com 2 discos rígidos de 480 GB. Este exemplo pega um desses discos, cria três partições (BIOS, swap e raiz) e formata a partição de swap como swap e a partição raiz como ext4.

Exemplo para servidores somente UEFI​

Temos alguns servidores legados, o c2.large.arm e o c2.medium.x86, que são somente UEFI. É necessário usar uma partição EFI FAT32 para o /boot/efi. Este é um exemplo de configuração para o c2.medium.x86, que possui 2 SSDs de 120 GB e 2 SSDs de 480 GB.
