Trying to install vertica on a 3 mode cluster with k-safety=1. What is the suggested RAID configuration for Vertica in such cases?

  • Hi Umesh, RAID 0 OR RAID 5..... Basically you need to understand the K-safety feautre is just for the safety of the database and is only on the database level. While RAID is for the OS level. I would suggest, If you have a production cluster go with RAID 5. If it is a Development cluster then you can opt for RAID 0 as there is no mirroring in RAID 0 RAID 5 because - Best cost effective option providing both performance and redundancy. Use this for DB that is heavily read oriented. Write operations will be slow.
  • Hi all, Actually, Vertica typically recommends RAID 10. Though some other configurations also work. https://my.vertica.com/docs/6.1.x/HardwareDocs/HP_Vertica%20Hardware%20Planning%20Guide.pdf -- May require you to be logged into my.vertica.com first Adam
