Description
The Database and Engineering Services Group of CERN's Information
Technology Department provides the Oracle based Central Data Base services used
in many activities at CERN.
In order to provide High Availability and ease management for those
services, a NAS (Network Attached Storage) based infrastructure has been set
up. It runs several instances of the Oracle RAC (Real Application Cluster)
using NFS as share disk space for RAC purposes and Data hosting. It is composed
of two private LAN's to provide access to the NAS file servers and Oracle RAC
interconnect, both using network bonding. NAS nodes are configured in
partnership to prevent having single points of failure and to provide automatic
NAS fail-over.
This presentation describes that infrastructure and gives some advice
on how to automate its management and setup using a Fabric Management framework
such as Quattor. It also covers aspects related with NAS Performance and
Monitoring as well Data Backup and Archive of such facility using already
existing infrastructure at CERN.
Summary
Experience and Lessons learnt from running high availability databases on Network
Attached Storage.
