Par convention, le préfixe c désigne « calcul » (''compute'') et le préfixe p désigne « persistant » (''persistent''). Le préfixe est suivi du nombre de CPUs virtuels, d'un tiret, puis de la quantité de mémoire vive. Si le nom du gabarit comprend un deuxième tiret, il est suivi de la taille du disque éphémère secondaire. | |||
A virtual machine of "c" flavor is intended for jobs of finite lifetime and for development and testing tasks. It starts from a [https://en.wikipedia.org/wiki/Qcow qcow2]-format image. It's disks reside on the local hardware running the VM and have no redundancy ([https://en.wikipedia.org/wiki/Standard_RAID_levels#RAID_0 raid0]). The root disk is typically 20GB in size. "c" flavor VMs also have an secondary ephemeral data disk. These storage devices are created and destroyed with the instance. The Arbutus (West) cloud treats “c” flavors differently as they have no over-commit on CPU so are targeted towards CPU intensive tasks. | A virtual machine of "c" flavor is intended for jobs of finite lifetime and for development and testing tasks.
