1. CB-Spider VM Spec Info Overview

• Users can set a VM Spec Name to request VM creation that conforms to the properties of that spec (vCPU, memory size, etc.).

• The relationship between VM Spec information provided by CB-Spider and the information of VMs created from those specs is shown in the diagram below.

• Users can utilize the abstracted CB-Spider VM Spec information to request VMs with their desired environment (number of CPUs, memory size, etc.).

  

2. CB-Spider VM Spec Info API Specification

• Users can retrieve VM Spec information in JSON format via the following CB-Spider REST API:

  GET /vmspec            - List VM Specs
  GET /vmspec/{Name}     - Get VM Spec
  GET /vmorgspec         - List Original VM Specs
  GET /vmorgspec/{Name}  - Get Original VM Spec
  

• The information included in the returned JSON result is as follows:

  Field	Description	Example Values
  Name	VM Spec Name managed and provided by the CSP	● t2.micro, Standard_D2a_v4, etc.
  Region	Region Name where the VM Spec is available	● us-east-1, northeurope, etc.
  VCpu	CPU resource info of the VM created from the spec, consisting of Count and ClockGHz (frequency)	● {2, 2.5}, {32, 3.0}, etc. ● -1: value not provided by the CSP
  MemSizeMiB	Memory size of the VM created from the spec	● 1024, 16384, etc.
  DiskSizeGB	Root Disk size of the VM created from the spec; may include temporary disk space depending on the CSP	● 8, 100, etc. ● -1: value not provided by the CSP
  Gpu	GPU info available to the VM created from the spec, consisting of Count, Mfr (manufacturer), Model, MemSizeGB (per GPU), TotalMemSizeGB (total GPU memory)	● {2, NVIDIA, Tesla T4, 16, 32}, {8, NVIDIA, H100, 85, 687}, etc. ● NA | -1: value not provided by the CSP
  KeyValueList	Original VM Spec information from the CSP in Key/Value List format	● "KeyValueList" : [ { "Key" : "AutoRecoverySupported", "Value" : "false" }, { "Key" : "Hypervisor", "Value" : "nitro" }, …

                 "TotalMemSizeGB" : "3072"
              }
           ],
           "KeyValueList" : [
                 {
                    "Key" : "AutoRecoverySupported",
                    "Value" : "false"
                 },
                 {
                    "Key" : "GpuInfo",
                    "Value" : "{Gpus:[{Count:8,Manufacturer:NVIDIA,MemoryInfo:{SizeInMiB:366211},Name:L40S}],TotalGpuMemoryInMiB:2929688}"
                 },
                 …
           ]
  }
