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
