Provider and costs
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 #The 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.

Requirements
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, #Node 3 hardware, and #Storagebox hardware have been rented for that purpose.

Storagebox hardware
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
- 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.
