HA Edition
Sybase
VCS Agent for Oracle
VERITAS Volume Manager
VERITAS File System with (Cached) Quick I/O
Volume Manager Storage Administrator
Database Edition for Oracle
Product Positioning
VERITAS Database Edition for Sybase offers raw device performance with file system manageability.• Offers equal to raw performance and for high-
memory systems even greater performance • Offers ease of management of file systems• Increases availability of Sybase dataservers
Key Features
VxFS with Quick I/O delivers raw disk performance and ease of file system administration• Equal or better OLTP throughput
Ease-of-use is provided with a Java-based Storage Administrator GUI• Visual configuration from a single console
HA Edition provides automatic monitoring and recovery of Sybase application
Raw I/O Performance withEase of File System Management
Manageability “Invisible” locations for segments Difficult to grow segments
Unique, total storage foundation solution to deliver the best of both worlds

Quick I/O for Databases
Breakthrough VERITAS File System interface technology
Presents regular VERITAS File System files to Oracle as raw character devices
• Allows parallel updates to database files for increased throughput• Takes advantage of kernel async I/O (Solaris’ KAIO)• Sybase handles locking for data integrity
Eliminates traditional UNIX file system overhead

OLTP Benchmark Results
Quick I/O and raw disk I/O produce equal performance for OLTP benchmark• Derived from TPC-C - mix of read-only and update-
intensive transactions in order-entry environments
All configurationsinclude VERITASVolume Manager.

Raw Partitions
Cached Quick I/O Overview
Implemented as a buffered read, direct write solution• Retains data reliability advantage of direct write• Gains read-ahead at the File System and memory-to-
memory copy performance advantage
Easy online management to turn Cache on/off for Quick I/O files• Like Quick I/O, enabled on a per-file basis
Multiple database instances can co-exist with selective caching for specific datafiles
VERITAS Storage Administrator
Simplifies Management
• Allows one-step graphical execution of common configuration management steps
