Exadata Intelligent Storage Grid

• Data Intensive processing runs in Exadata Storage Grid

• Filter rows and columns as data streams from disks (168 Intel Cores)

• Example: How much product X sold last quarter

• Exadata Storage Reads 10TB from disk

• Exadata Storage Filters rows by Product & Date

• Sends 100GB of matching data to DB Servers

• Scale-out storage parallelizes execution and removes bottlenecks


Simple Query Example

Select sum (sales) where Date=‘24-Sept’

Optimizer Chooses Partitions & Indexes to Access

• Scan compressed blocks in partitions / indexes

• Retrieve sales amounts for Sept 24

• 10 TB scanned • 1 GB returned

to servers

Exadata Storage Index Transparent I/O Elimination with No Overhead

• Exadata Storage Indexes maintain summary

information about table data in memory • Store MIN and MAX values of columns

• Typically one index entry for every MB of disk

• Eliminates disk I/Os if MIN and MAX can never

match “where” clause of a query

• Completely automatic and transparent

Max B =8

Select * from Table where B<2 - Only first set of rows can match


Exadata Hybrid Columnar Compression Highest Capacity, Lowest Cost

• Data is organized and compressed by column

• Dramatically better compression

• Speed Optimized Query Mode for Data Warehousing

• 10X compression typical

• Runs faster because of Exadata offload!

• Space Optimized Archival Mode for infrequently accessed data

• 15X to 50X compression typical

Exadata Migration


Exadata X3 “Database In-Memory Machine”

X3 mass memory hierarchy delivers extreme

performance – Automatically moves all active data from disk to memory

DRAM memory expanded to 2 or 4 TB for hottest data

– 4 to 40 TB of compressed user data????

Flash memory expanded 4X to 22 TB per rack

– 40 to 200 TB of compressed user data – ALL active data

– 1.5 Million SQL random read I/Os per second for OLTP

Comparable to 15,000 disk drives in 150 array frames

– 100 GB/sec SQL data scan rate for reporting and warehouses

Comparable to 1,000 disk drives in 10 array frames

Exadata X3-2 Database Server Update New Intel 8-core E5 “SandyBridge” CPUs, more memory, 10GbE

Notes:

Xeon E5 (Sandy Bridge) internal architecture gives higher performance with lower clock speed

Disk Controller, Disks, and InfiniBand are Unchanged

Unlike X2, no performance penalty for memory expansion

PCIe Bus Gen 2.0 Gen 3.0 Future. Requires Gen 3 cards

Effective Dec 11, 2012, we start shipping new X3-2 orders with the increased memory in the database

servers. We will ship X3-2 database servers with 256GB of memory installed by default instead of the

previous default of 128GB. This is the maximum amount of memory that is currently supported in the Exadata

X3-2. There is no hardware price increase for the extra memory.

Notes

Kept Storage CPU at 6-core low power processor. Embedded storage CPU requires much less

throughput than DB CPU.

Disk Controller and InfiniBand card are unchanged.

Internal memory increased from 24GB to 64GB for managing large flash.

PCI 3.0 included in new servers but will not see benefit until cards redesigned for 3.0.


X3 Upgrades

X2 or V2 systems can be expanded with X3 hardware

– A single Database Machine can have servers from

different generations

– Databases and Clusters can span across multiple

generations of hardware

As always we don’t replace servers or components inside

the servers

– We expand by adding new servers

– Obsolete servers are removed

X3 hardware requires recent Exadata software release (>=

11.2.3.2.0) since servers require new drivers, firmware, etc.

– X3 hardware does not require a Database, ASM, or

Clusterware upgrade

Exadata X3-2 Storage Expansion Rack

Exadata Storage Expansion Rack has also been updated with X3

storage servers

Main benefit is much larger flash

– 28.8 TB of flash per full rack

– Disk capacity per rack remains 648 TB Raw

Can be connect to Exadata or SPARC SuperCluster as always

Can be connected to new or older generation database machines


NEW Exadata X3-2 Eighth Rack Faster Than 2010 Quarter-Rack, 2008 Half-Rack

Lowest Cost Exadata Configuration

– Hardware List price $200K: 60% of Quarter Rack

– 16 Database Cores, 54 TB Disk, 2.4 TB PCI Flash

– Highly Available configuration with all Exadata features

Brings Exadata Extreme Performance to smaller workloads,

development, test, disaster recovery

Hardware Identical to Quarter-Rack

– Half CPU Cores, Disks, and Flash Cards Disabled

– Half the Database and Exadata Software Licenses

New Exadata Software

11.2.3.2.0

Features work on all hardware generations


Exadata Smart Flash Cache Write-Back Cache Accelerates Write Performance 20X

New software caches write I/Os in flash memory

– Now all reads and writes of active data go to flash

– 1 Million 8K flash write I/Os per second on an X3 rack

Comparable to 10,000 disks on 100 array frames

20X more writes than previous Exadata version

– New software also provides 10x write improvement on

existing V2 and X2 systems

Cache is persistent and fully redundant

– Also improves database availability by accelerating write

intensive recovery

Flash Cache Advantages over Flash Tiering

Teradata, EMC, Hitachi, IBM, etc. use flash tiering

Exadata Flash Cache adapts much faster to changing workload

– Each I/O changes content of cache

– If new data is created it can be instantly cached

– With tiering, data is slowly migrated from disk based on historical statistics

– Flash tiering caches yesterday’s hot data, not necessarily today’s

Exadata Cache has much finer granularity of flash contents

– Caching at 64K chunks for flash cache, around 1MB for flash tiering

– Caching is much more efficient at capturing hot data in flash while leaving cold data on disk. Multiplies the

effective capacity of flash.

Exadata Cache doesn’t need to mirror data in flash

– Can keep one mirror copy in flash to speed up reads while having the other mirror copy on disk

Flash cache can keep hot blocks cached forever

– There is no need to ever de-stage them to disk. This is not a tiering advantage
