Prepare Cluster Hardware

This section describes the cluster hardware preparation required for the installation of an Exasol cluster.

Hardware (Database nodes)

BIOS

  • Disable EFI Disable C-States (Maximum Performance)
  • Enable PXE on "CICN" Ethernet interfaces
  • Enable Hyper threading
  • Boot order: Boot from PXE 1st NIC (VLAN CICN)

RAID

  • Controller RW-Cache only enabled with BBU
  • Best practice is to configure physical disks as RAID-1 pairs. For example, if you have 16 physical disks, you would configure this as 8 x RAID-1 volumes.
  • Keep the default strip size
  • Keep the default R/W cache ratio

LOM Interface

Enable SOL (Serial over LAN console)

Management node (License node)

BIOS

  • Disable EFI Disable C-States (Maximum Performance)
  • Enable Hyper threading
  • Boot order: Boot from disk

RAID

  • Controller RW-Cache only enabled with BBU
  • All disks are configured as RAID-1 mirrors (best-practice, for different setup ask Exasol Support)
  • Keep the default strip size
  • Keep the default R/W cache ratio

LOM Interface

Enable SOL (Serial over LAN console)
