Flavors

BST-PL2 region flavors naming convention is defined based on structure below:

[purpose][version]-[storage]-[cpu][vcpu]-[ram]R-[disk]D

  • Purpose with Version: Abbreviation indicating the intended use case with version number.
    • M1, M2, etc.: Medium (General Purpose), followed by the version number.
    • C1, C2, etc.: Compute Optimized, followed by the version number.
    • R1, R2, etc.: Memory Optimized, followed by the version number.
    • G1, G2, etc.: GPU instance
  • Storage Type: Indicator of the storage technology used.
    • NVME: NVMe storage
    • NET: Network storage
  • CPU Type: Indicator of CPU allocation type.
    • vCPU: Overbooked virtual CPUs
    • CPU: Dedicated CPU cores
  • vCPU/CPU: Number of virtual CPUs or CPU cores.
    • Numeric value followed by vCPU or CPU.
  • RAM: Amount of RAM in gigabytes.
    • Numeric value followed by R (e.g., 8R for 8 GB of RAM).
  • Disk Size: Amount of disk space in gigabytes.
    • Numeric value followed by D (e.g., 50D for 50 GB of disk space).

Virtual Machines local/network storage

Virtual machines can have a system disk (root disk) on the host's local disks or on Ceph storage. Both methods of running a virtual machine have different properties.

  • Virtual machine on local NVME disk

Important

An NVME type machine is an ephemeral instance. This means that in the event of a host failure, the system disk of the instance is unrecoverable, and a new virtual machine must be launched, potentially connecting the network storage that was previously attached to the damaged instance.

Creating an NVME type virtual machine: An NVME VM is created using NVME-type flavors, e.g., M1-NVME-2vCPU-8R-50D.

Important

When using the Horizon panel, remember to select the option "Create new volume: No" in the "Source" tab. Otherwise, the virtual machine will be created on a Ceph volume instead of the local NVME disk.

  • NET type virtual machine on Ceph storage

A NET type machine has a disk on network storage. Such a VM can be fully backed up and recovered in the event of a host failure.

Creating a NET type virtual machine: A NET VM is created using NET-type flavors, e.g., M1-NET-2vCPU-8R. The disk size is specified when creating the virtual machine.

Network

Users have access to the following external networks:

  • PSNC-INTERNAL-LAN - a non-public network accessible via PCSS VPN
  • PSNC-EXT-PUB1-EDU - a public network for educational projects
  • PSNC-STORAGE-MANILA - a network with access to shared CephFS storage

Storage

The BST-PL2 region provides the following storage resources:

  • Ceph NVME: Ceph_Frappuccino_NVME - quota provided on request
  • Ceph HDD: Ceph_Frappuccino_HDD
  • CephFS storage: CephFS-Frappuccino
