effective storage capacity and increases user data scan bandwidths by a factor of up to 10X

• Exadata Smart Flash Cache• Breaks random I/O bottleneck by

increasing IOPs by up to 20X

• Doubles user data scan bandwidths

• I/O Resource Manager (IORM) • Enables storage grid by prioritizing

I/Os to ensure predictable performance

• Quality of Service (QoS)

• Actively meet and maintain SLAs

• Memory Guard to protect existing

current transactions from memory-

based failures

Exadata智能存储

• Exadata storage servers also run more complex operations in storage

• Join filtering

• Incremental backup filtering

• I/O prioritization

• Storage Indexing

• Database level security

• Offloaded scans on encrypted data

• Data Mining Model Scoring

• 10x reduction in data sent to DB servers is common

1 – Raw capacity calculated using 1 GB = 1000 x 1000 x 1000 bytes and 1 TB = 1000 x 1000 x 1000 x 1000 bytes.

2 - User Data: Actual space for end-user data, computed after single mirroring (ASM normal redundancy) and after

allowing space for database structures such as temp, logs, undo, and indexes. Actual user data capacity varies by

application. User Data capacity calculated using 1 TB = 1024 * 1024 * 1024 * 1024 bytes.

CUSTOMER PERSPECTIVE

Customer understands the potential of providing the video service for its subscribers however their large data volumes and current legacy architecture are ineffective. Sun Oracle DB Machine was the answer to performance issues faced by its legacy application.

CUSTOMER OVERVIEW

The largest among all overseas listed Chinese companies and among all the telecom carriers in Asia based on market value.

CHALLENGES/OPPORTUNITIES

The AAA processing system is a Mobile Video Center which serves mobile video service to subscribers. The current system is unable to process subscriber requests as per the expected service levels due to heavy traffic and I/O bottleneck.

In addition customer and SI does not have the experience to run a RAC system effectively.

SOLUTIONS

• Half Rack of Oracle DB Machine with Oracle RAC, Partition and Billing and Oracle Revenue Management Systems

• Running OLTP workload on a preconfigured, grid ready data and storage environment.

RESULTS

Query results for video service improved 4X and application response time stabilized.

Subscribers base for their online video services is growing three times faster than the legacy system due to better service.

Simplified management and administration with no learning curve.
