Server specifications

Check the server type and image provided by NAVER Cloud Platform before creating a server.
NAVER Cloud Platform provides servers from g1 to g3.

  • 1st generation (g1) server: The original version developed at the initial launch of the service. They are the XEN hypervisor-based servers where you can use HDD and SSD-based storage.
  • 2nd generation (g2) server: An improved version with enhanced CPU and network performance and greater stability compared to 1st generation servers. They are the XEN hypervisor-based servers where you can use HDD and SSD-based storage.
  • 3rd generation (g3) server: KVM hypervisor-based servers introduced for improved performance over previous generations. Unlike g1/g2 servers, g3 servers have distinct compatibility for servers, storage, snapshots, and server images. Available storage types include FB1/2 (Fixed Block Storage) and CB1/2 (Common Block Storage).
Note
  • Resources with different hypervisors are not compatible with each other.
  • Currently, g3 servers are supported only in the Korea, Singapore, and Japan Regions.

Overview by hypervisor

Hypervisor is a concept added to categorize the compatibility of resources (services) provided by NAVER Cloud Platform. NAVER Cloud Platform provides XEN and KVM hypervisors, and the following resources (services) are classified by hypervisor compatibility:

Hypervisor Server generation Server type Server image (OS) Storage type Snapshot My server image
XEN g1, g2 Mirco, Standard, High-Memory,
High-CPU, CPU-Intensive, GPU
XEN-based server image HDD, SSD XEN-based snapshot XEN-based My server image
KVM g3 Mirco, Standard, High-Memory,
High-CPU, CPU-Intensive, GPU, SFC
KVM-based server image FB1, FB2
CB1, CB2
KVM-based snapshot KVM-based My server image
  • Server
  • Storage (Block Storage)
  • Snapshot
  • My server image (Server Image)
Caution

Resources (services) with different hypervisors are not compatible with each other.
For example, you cannot create a server based on KVM from My server image created with a server based on XEN.

Characteristics of KVM-based server

Unlike XEN-based g1 and g2 servers, KVM-based g3 servers have the following characteristics:

  • g3 server spec codes do not include storage information (e.g., B50, B100).
  • g3 server names exclude disk information. Example: 2 vCPUs, 4 GB memory.
  • As for g3 servers, the storage information is excluded from the existing OS SW code.

The following is the performance QoS by specification for KVM-based g3 servers:

Note

The maximum possible performance values are displayed for the network, storage IOPS, and storage throughput.

Server spec code

Server spec code is a code developed for viewing the specifications of a server at a glance. You can find it when creating servers or checking the information of a created server.
The indication rules of the code are as follows:

mi 1 - g3 a (-h50)
Server type Number of vCPUs - Server generation CPU type Storage type/capacity
Item Description
Server type
  • mi: Micro server
  • cp: Compact server
  • s: Standard server
  • m: High Memory server
  • c: High CPU server
  • ci: CPU Intensive server
Number of vCPUs Number of CPU cores (number of Hyperthread on criteria for Bare Metal Server)
Server generation
  • g1: 1st generation server
  • g2: 2nd generation server
  • g3: 3rd generation server
CPU type
