Overall Architecture
...
This blueprint is expected to run on multiple environments (libvirt, AWS and baremetal).
Deployments to AWS
| nodes | instance type |
|---|---|
| 1x bootstrap (temporary) | EC2: m4.xlarge, EBS: 120GB GP2 |
| 3x masters | EC2: m4.xlarge, EBS: 120GB GP2 |
| 3x workers | EC2: m4.large, EBS: 120GB GP2 |
Deployments to Bare Metal
| nodes | requirements |
|---|---|
| 1x provisioning host (temporary) | 12 cores, 16GB RAM, 200GB disk free, 3 NICs (1 internet connectivity, 1 provisioning+storage, 1 cluster) |
| 3x masters | 12 cores, 16GB RAM, 200GB disk free, 2 NICs (1 provisioning+storage, 1 cluster) |
| 3x workers | 12 cores, min. 16GB RAM, 200GB disk free, 2 SR/IOV-capable NICs (1 provisioning+storage, 1 cluster) |
The blueprint validation lab uses 7 SuperMicro SuperServer 1028R-WTR (Black) with the following specs:
| Units | Type | Description |
|---|---|---|
| 2 | CPU | BDW-EP 12C E5-2650V4 2.2G 30M 9.6GT QPI |
| 8 | Mem | 16GB DDR4-2400 2RX8 ECC RDIMM |
| 1 | SSD | Samsung PM863, 480GB, SATA 6Gb/s, VNAND, 2.5" SSD - MZ7LM480HCHP-00005 |
| 4 | HDD | Seagate 2.5" 2TB SATA 6Gb/s 7.2K RPM 128M, 512N (Avenger) |
| 2 | NIC | Standard LP 40GbE with 2 QSFP ports, Intel XL710 |
Networking for the machines has to be set up as follows:
Deployments to libvirt
| nodes | requirements |
|---|---|
| 1x bootstrap (temporary) | 2 vCPUs, 2GB RAM, 2GB (sparse) |
| 3x masters | 4 vCPUs, 8GB RAM, 2GB (sparse) |
| 3x workers | 2 vCPUs, 4GB RAM, 2GB (sparse) |
