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
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
“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 12
• Virtualized HA requires reimaging
• Default 12.2
– Lower versions:
• Download
• Add to repository
• Install
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…
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

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
Quality. Passion. Personality.
