Information Outline for Oracle RAC Virtual Server sandbox Plan

This document describes the proposed plan to implement a two-node Oracle RAC cluster on the ESXi R710 Dev Host for sandbox purposes. Below you will find detailed technical specifications for building the RAC-Virtual Sandbox

Document Creator Todd Walters

Virtual Servers Configurations

Will build two virutal servers on ESXi Host srv0esxt01 TEST.
Oracle Virtual Servers will adhere to these specifications on Dell r710 Host:

4gb Memory
50gb Hard Drive
4 Virtual CPU
Vlan 126 for Test
Storage for Virtual Servers on l0esxt01vmfs02

Virtuals Servers information:

Hostname: srv0sbox01 IP: 192.168.91.31 VIP=192.168.9.33 IC=192.168.4.91
Hostname: srv0sbox02 IP: 192.168.91.32 VIP=192.168.9.34 IC=192.168.4.92

ASM Storage Considerations

Create 5 5gb ASM Disks with following configurations:

4 ASM Disks would become sandbox_data1 Diskgroup: 20gb ASM Storage
1 ASM disk would become sandbox_backup1 diskgroup: 5gb ASM Backup

ASM Storage has two options:

Store ASM disks on SAN on r710 storage as virtual storage.
Create LUN consiting of mirror pair on SAN, then create ASM virtual disks on SAN.
