Bureau Infrastructure
Bureau Infrastructure (hereinafter, #The Infra) is the software and hardware that CNMCyber Team rents to host CNM Bureau Farm. The rented software and hardware consists of #The Metal and #The Bridges. Both are parts of Opplet Infrastructure.
In a nutshell
Needs to satisfy
- In Opplet Infrastructure, #The Infra is the newest, most expensive part. It hosts the most critical pieces of Opplet's software such as Opplet.net, CNMCyber.com, and CNM Corp. To ensure high availability (HA) of the hosted software, it includes three bare-metal servers.
The Provider
- For the purposes of this very wikipage, the Provider refers to Hetzner, which has been serving as #The Team's Internet service provider (ISP) and lessor of both #The Infra and Lab Infrastructure since 2016. Offers from other potential providers, specifically, Contabo and DigitalOcean, have been periodically reviewed, but no one else has offered any better quality/price rate on a long-term basis.

Assumptions
Due to the lower cost, #The Metal's rentals were purchased via #The Provider's auction -- https://www.hetzner.com/sb?hdd_from=500&hdd_to=1000 -- based on the following assumptions.
Number of nodes
- ProxmoxVE normally requires three nodes. The third node is needed to provide quorum; however, it shall not necessarily run applications. At the same time, Ceph's non-emergency operations require three nodes at least.
Hard drives
- The hard drive storage capacity for any of #The Nodes shall be 512Gb at least.
- Because Ceph is selected to power #The Storage, any hard-drive of #The Metal shall be both SSD and NVMe.
Processors
- The processor frequency for two Nodes of #The Metal shall be 32Gb at least. Processor frequency requirements to the third of #The Nodes may be lower because of ProxmoxVE's characteristics.
- Those servers that deploys Intel Xeon E3-1275v5 processors are preferable over those servers that deploys Intel Core i7-7700 ones.
Location
- At least two Nodes shall be located in the same data center. Although #The Provider does not charge for internal traffic, this circumstance increases the speed of #The Farm as a whole. If no nodes are available in the same data center, they shall be looked for in the same geographic location.
The UI
With regards to #User interfaces (UIs), administrative access to #The Metal can be accomplished through several tools and portals that #The Provider grants to CNMCyber Customer.
GI
- Its graphic interface belongs to #Dashboards.
CLI
- For the purposes of this very wikipage, a command line refers to a command line interface (CLI) of any of #The COTS packages installed in #The Farm. This input-output line area allows #The Sysadmins and #The Superusers to interact with #The Cluster and #The Infrastructure rather than screen-based graphical buttons, icons, or hyperlinked texts in graphic user interfaces (GUIs).
The Metal
#The Habitat is deployed on three bare-metal servers and one storage box. As the result of #Choosing the metal, #1736579, #1777698, #2109682, and #Storagebox hardware have been rented for that purpose.

The Bridges
Hetzner vSwitches (hereinafter, the Bridges) serve as bridges for #Communication channels to connect #The Nodes in networks and switch from one of #The Nodes to another. #The Cluster utilizes two Bridges, which are #Internal Bridge and #External Bridge.
#The Provider provides #The Team with the Bridges; They come with the lease of #The Metal. #The Team can order up to 5 connectors to be connected to one of #The Node's servers.
#The Farm cannot support high availability of the Bridges. Resiliency of the Bridges is the courtesy of their owner, #The Provider.

- External Bridge serves as the hub for the public network, the Internet. It is located on external, public IPv4 address to provide for data transfer between #The Farm's publicly-available and other Internet resources.
Сеть каждого Узла использует мост по выбираемой по умолчанию в Network Configuration модели.
Internal Bridge
- Internal Bridge serves as the hub for node and storage networks. It is located on an internal, private IPv6 address to provide for data transfer between #The Nodes and their storage spaces.
Сеть каждого Узла использует мост по выбираемой по умолчанию в Network Configuration модели.
