Tuned profiles for Eucalyptus

Follow

Eucalyptus Versions:  3.0 - Current

Introduction

Red Hat and CentOS (and other distributions) provide a number of pre-defined performance profiles for specific use-cases using the tuned utility.  These profiles can be activated on hosts dynamically and automatically.  This article covers the recommended profiles for Eucalyptus components on RHEL6/CentOS6 hosts.

Setting a Profile

A profile can be set using the tuned-adm [1] command:

tuned-adm profile enterprise-storage

Recommended Profiles

Component Profile
Node Controller*

"virtual-host" or "enterprise-storage"

Storage Controller

"enterprise-storage"

Cluster Controller*

"throughput-performance" or "latency-performance"

Walrus

"enterprise-storage"

Cloud Controller

"throughput-performance" or "latency-performance"

Object Storage Gateway

* WARNING: On a node controller using EDGE OR a Cluster Controller co-located with the Storage Controller in MANAGED/MANAGED-NOVLAN, you must ensure that ip fowarding is enabled in sysctl.conf [2]
