No. of HDDs per Node Configuration
168
  • Two Teradata Database nodes plus one hot standby node to four disk arrays (2:4 ratio)
  • 42 AMPs per node (APN)
  • 168 HDDs per active node (no mixed drive types or sizes in each disk array)
  • Used with 6700C
  • SSD upgradable
Variable Configuration
  • Two Teradata Database nodes plus one hot standby node to four disk arrays (2:4 ratio)
  • Up to 46 AMPs per node (APN)
  • Up to 184 HDDs per active node in multiples of 4 or 6 (no mixed drive types or sizes in each disk array)
  • Used with 6700C
  • Cannot be upgraded to SSDs

Guidelines differ depending on whether the configuration is a variable configuration.

For a 6800C 2+1 clique with four disk arrays, coexisting with a 6700C system, the following guidelines apply:

  • Two Teradata Database nodes plus one hot standby node to four disk arrays (2:4 ratio)
  • 42 AMPs per node
  • 168 drives per node (no mixed drive types or sizes in each disk array)
  • 84 drives per array

For a 6800C 2+1 clique with four disk arrays, coexisting with a 6700C system, and using a variable configuration, the following guidelines apply:

  • Two Teradata Database nodes plus one hot standby node to four disk arrays (2:4 ratio)
  • Up to 46 AMPs per node
  • Up to 184 drives per node (no mixed drive types or sizes in each disk array)
  • Up to 92 drives per array in 4 arrays
