Using Cluster File Systems
VERITAS Storage Foundation Cluster File System (SFCFS) is the file system clustering
functionality of VxFS. SFCFS is a separately licensable feature of VxFS that requires several other
VERITAS products to enable communication services and provide shared disk storage resources.
VERITAS Cluster Server and VERITAS Volume Manager are packaged with VxFS to provide a
complete clustering environment. There is also a high availability version, VERITAS Storage
Foundation Cluster File System HA. See “Technical Support” on page 53 for contact information
on these products.
VERITAS Storage Foundation for Oracle
VERITAS Storage Foundation for Oracle combines the strengths of the core VERITAS products
with database-specific enhancements to offer unrivaled performance, availability, and
manageability for databases. The database feature options are as follows:
VERITAS FlashSnap Option
The VERITAS FlashSnap option, when applied to databases, lets you create, resynchronize, and
reverse resynchronize volume snapshots for databases. The snapshots can be used on a second host.
Also, database administrators can perform these tasks without root privileges.
This option is available with the Enterprise version of VERITAS Storage Foundation for Oracle.
VERITAS Quick I/O Option
VERITAS Quick I/O is a VERITAS File System feature that improves the throughput for databases
built on VERITAS File Systems. Quick I/O delivers raw device performance to databases run on
VxFS, providing the administrative advantages of using file systems without performance
penalties. VERITAS Cached Quick I/O further enhances database performance by leveraging large
system memory to selectively buffer frequently accessed data.
This option is available with the Enterprise version of VERITAS Storage Foundation for Oracle.
VERITAS Extension for Oracle Disk Manager Option
VERITAS Extension for Oracle Disk Manager is a custom storage interface designed specifically
for Oracle9i and 10g. Oracle Disk Manager improves the performance and manageability of system
bandwidth through an improved application programming interface (API) that contains advanced
kernel support for file I/O.
This option is available with both the Standard and Enterprise versions of VERITAS Storage
Foundation for Oracle.
