Bureau Infrastructure

Bureau Infrastructure is the software and hardware that CNMCyber Team rents from Hetzner to host CNM Bureau Farm. The rented software and hardware consists of #The Metal and #The Bridges. Both are parts of Opplet Infrastructure.

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.

Choosing the metal

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: 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:
  1. The hard drive storage capacity for any of #The Nodes shall be 512Gb at least.
  2. Because Ceph is selected to power #The Storage, any hard-drive of #The Metal shall be both SSD and NVMe.
• Processors:
  1. 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.
  2. 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 hardware characteristics of the chosen Nodes are presented in #The Metal section below.

UI for the Metal

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. Its graphic interface belongs to #Dashboards.

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, #Node 1 hardware, #Node 2 hardware, #Node 3 hardware, and #Storagebox hardware have been rented for that purpose.
