Overview and evolution of ODA

and all of its flavours

Introducing ODA

3/2/2018 2

• “Appliance”

– Intended as a black box

– Database server(s)

– Storage

– Only for databases

• Later also VM’s

Objectives

3/2/2018 3

• Simplicity

– Setup

– Maintenance

• Patching

• Performance

• High availability

History

3/2/2018 4

Today

3/2/2018 5

Entry X7-2S

10 Cores

Performance X7-2M

36 cores

High availability X7-HA

72 Cores

Current models

X7-2S

• 10 cores

• 192G...384G memory

• 12Tb

– 2xSSD

• Oracle SE or EE

X7-2M

• 36 cores

• 384G...768G memory

• 12..51Tb SSD

– 12T (2xSSD)

– 32T (5xSSD)

– 51T (8xSSD)

• Oracle SE or EE

3/2/2018 6

Current models

3/2/2018 7

• ODA X7-HA– 2 nodes

– 72 cores

– Storage (raw)• High performance: 16-128Tb SSD (5..40 disks)

• High capacity: 150..300Tb HDD (15 or 30 disks)

• 2 or 3 way mirroring

– 384..768G memory/server

– Oracle SE or EE

Evolution storage - cores

3/2/2018 8

“Unboxing”

3/2/2018 9

• Connect ILOM, power, network

• Checklist– Names, IP Adresses

– DNS

– NTP

– …

• Configuration– DATA vs FRA

Software

3/2/2018 10

• Oracle SE or EE– SE only since X6

• Grid infrastructure

• ASM or ACFS

• Db versions– 11.2

– 12.1

– 12.2

Deployment

3/2/2018 11

Deployment

3/2/2018 12

• Virtualized HA requires reimaging

• Default 12.2

– Lower versions:

• Download

• Add to repository

• Install

Create database

3/2/2018 13

Backup options

3/2/2018 14

• Internal

– Storage: 10..90% +RECO vs +DATA

– Rman to FRA

• External

– Use up to 90% for +DATA

– NFS share

– Backup agent

• E.g. Oracle Secure Backup

Patch / Upgrade (infrastructure)

3/2/2018 15

• “1 patch to rule them all”

• All components– Disks

– Controllers

– OS

– GI

– Databases

• It just takes some (down)time…

Upgrade (database)

3/2/2018 16

• Recently

– Appliance GUI

Virtualization - OVM

3/2/2018 17

• X7-2 HA only

– Reimage required

– Oracle VM

– Components

• Dom0

• ODA_BASE

• Guest domains

– VM’s on shared storage

Virtualization - KVM

3/2/2018 18

• Intended for X7-2S and X7-2M

• Based on linux KVM

– Simpler setup

• Cannot be used to limit db licenses

• No db’s inside VM’s

ASR

3/2/2018 20

• Automatic Service Requests

• Hardware failures

– Disk

– Power supply

– …

• Some parts are

“customer-replaceable”

X7-HA only

3/2/2018 21

• Oracle VM

– Import VM templates

– Clone VM templates

– Snap clones of vm’s

– Live migration

• oakcli

– Create snapshot db

Reliability

3/2/2018 22

• Dual sockets (except 2S model)

• Redundant private interconnect

• Redundant public networks

• Double-mirroring or triple-mirroring (2M/HA)

storage redundancy

• Redundant hot-swappable power,

cooling, and fans

Limitations

3/2/2018 23

• Root access

– Don’t mess it up

• Cleanup of log and trace files

• Hardware limitations

– 768G memory

– 300T storage

– # cores

Performance X6-2M

3/2/2018 24

• Single block reads

– ACFS

• 300k/sec

– ASM

• 680k/sec

Mixed workload

3/2/2018 25

• 100k reads

• 40k writes

• ASM vs ACFS

– similar

3/2/2018 26

charbench -c ../configs/SOE_Client_Side.xml -rt 0:02 -uc 25 -min 0 -max 0 -intermin 0 -intermax 0

112 Gb

select /*+ full(a) noparallel */ count(*) from largetab;

select /*+ full(a) parallel(12) */ count(*) from largetab;

Why ODA

Simplicity

• Hardware configuration

• Installation

• Storage config

– ASM, multipath

• Cluster, HA

• Patching

Performance

• Dedicated storage

– Consistent IO

• ASM striping

• ASM (intelligent) mirroring

Licencing

• Capacity on demand

3/2/2018 27

Why ODA

3/2/2018 28

• Consolidations

• Dedicated database/hardware

• Ease of installation/maintenance

• Simple HA

– 2 x X7-2S

– Oracle SE

– DbVisit standby
