Particionamiento personalizado y RAID (CPR)

Equinix Metal™ ofrece una función de Particionamiento y RAID personalizados (CPR), que le permite especificar la configuración del disco cuando despliega un servidor reservado.

Para utilizar la RCP, cree un objeto JSON que:

Indica qué discos quieres formatear.
Cómo quieres formatear estos discos.
Qué sistema de ficheros debe crearse en los discos.
Dónde montar la partición una vez creada.

Utilice los ejemplos para empezar a crear el suyo propio.

Requisitos del servidor reservado

Se requiere un servidor reservado porque el esquema de unidades exacto debe conocerse de antemano para que la personalización funcione a través de la API. La función de particionamiento y RAID personalizados no está disponible para instancias bajo demanda.

Aprovisionamiento con CPR

Para utilizar CPR, tendrá que desplegar un servidor a partir de sus reservas de hardware a través de la API. Cuando envíe su solicitud POST al punto final projects/<id>/devices, tendrá que enviar su configuración CPR como un objeto JSON con el parámetro storage en el cuerpo de la solicitud.

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>",
  }'

Ejemplos por servidor

c3.pequeño.x86

El c3.small.x86 viene con 2 unidades de 480 GB. Este ejemplo toma una de esas unidades, crea tres particiones (BIOS, swap y raíz), luego formatea la partición swap como swap y la partición raíz como ext4.

s3.xlarge.x86

El s3.xlarge tiene 2 x 960 GB SSD, 12 x 8 TB HDD y 2 x 256 GB de Flash NVMe. En este ejemplo, las 2 unidades SSD de 960 GB serán utilizadas por ROOT y SWAP en RAID 1, y las 12 unidades HDD de 8 TB serán utilizadas por DATA en RAID 10. Las unidades NVMe se dejan para otros fines. Las unidades NVMe se dejan para otros fines.

Ejemplo para servidores sólo UEFI

Tenemos algunos servidores Legacy, el c2.large.arm y el c2.medium.x86, que son sólo UEFI. Para el /boot/efi es necesario utilizar una partición EFI FAT32. Este es un ejemplo de configuración para el c2.medium.x86, que tiene 2 unidades SSD de 120 GB y 2 unidades SSD de 480 GB.
