Safra Catz, President and CFO of OracleOOW quote:

“I would like to introduce my good friend Tom Mendoza…………NetApp is a very, very close

partner of Oracle…..we have worked together for a very long time in advancing technology, grid

computing, and data center consolidation……..for any of you that has visited our Austin Data Center, it is a commercial for NetApp. We voted for them

with our money.”

Database Performance Tuning and Capacity Planning Challenges

Storage can be a performance bottleneck

Duplicate database copies are needed to maintain availability and SLAs

Performance of each volume is limited to the number of spindles within

“Hot” volumes can’t be “helped” by disks in other volumes

Capacity planning, forecasting and management are imprecise tasks

Availability, scalability and capacity must be maintained or increased while driving down costs…

Migrate Data Across Storage Tiers

Periodically move data between storage tiers as access patterns change– e.g. MOVE PARTITION holding Q2

Orders from high performance storage tier to low cost storage tier

Move important data on demand– UPDATE of partition key will cause

row to move to a new partition e.g. product warranty expires

Write protect data with SnapLock on any storage tier– e.g. MOVE PARTITION to SnapLock

volume and mark as “read only” and set the retention date.

Data passes through many layers before reaching the storage subsystem.

Corruption can occur at any point in the data path.

Prevention is better than recovery…

“… the larger outage was caused by a corruption of data files. The corrupted files began to replicate and quickly spread across the system, …” April 11, 2002

eBay suffers three outages in three days

Oracle® Database

Hardware and/or firmware failures, misconfiguration, etc.


SnapValidator: Prevents Oracle block corruption SnapValidator™ is NetApp’s implementation of

Oracle’s HARD initiative– HARD stands for Hardware Assisted Resilient Data

Validates writes to volumes that contain Oracle data– Oracle checksum verification

Feature of Data ONTAP Supported with Oracle Database 9i and 10g (NFS,

iSCSI, FCP) NetApp is the only HARD partner to support this

initiative across its entire product line. NetApp is the only HARD partner to support

filesystems.

Introducing Database NFS - DNFS

What is DNFS? – An Oracle developed and supported NFS client for

all platforms. (Including Windows)What are the benefits of DNFS?

– Simpler management with enhanced performance and scalability.

– No certification required immediate customer availabilityFully tested during development rather than after

deployment

– Supports RAC, ASM, and HARD across all operating environments


Performance

Automatic Link Aggregation– Users can specify multiple ethernet connections between the

Oracle database and the NFS server

– DNFS will distribute the load over all active links in a balanced fashion

Improved I/O Concurrency– Supports fully concurrent, asynchronous I/O on all platforms

Summary– Any Oracle application can easily take advantage of the

performance available on multiple parallel wires

– No other NFS client can do this…

High performance and high throughput, regardless of operating environment and without the need for expert tuning


Simplicity

Runs outside of the OS kernel– No integration with operating system’s virtual

memory or buffer cacheDNFS has a shorter code path faster than other

NFS clients with fewer bugs

No mount options– Already tuned for database operations

– Simple to set up fewer operational errors

– Fewer support calls
