Sun StorageTek QFS software provides high-performance,
heterogeneous data access over a SAN, and is ideal for
collaborative environments where large data volumes
require shared access. The software allows data to be
written and accessed at device-rated speeds, enabling
superior application I/O rates. It supports hundreds
of heterogeneous systems, and provides file sharing
using NFS, CIFS, Apple Filing Protocol, FTP, and
Samba.
Key Benefits
Provides simultaneous, shared access to files and data
Enables rapid data ingestion and access
Enhances collaboration
Allows you to tune file services for better performance
Reduces storage management costs
Simplifies storage management
High Performance Sharing
Enhanced collaboration
QFS provides users across the enterprise with shared, simultaneous, heterogeneous access to the same large files or data sets. Users and mission-critical applications share the same files and access large volumes of data with no degradation in performance. This robust file sharing improves collaboration and speeds time-to-market project completion. Up to 128 systems running QFS can have shared access to the same data while maintaining file integrity.
Rapid shared access
With QFS, you can quickly move large files or data sets into the file system, providing single or multiple users and applications to have rapid shared access. In conjunction with optional Sun StorageTek Storage Archive Manager (SAM) software, which enables users to reduce the cost of storing vast data repositories, QFS transfers processed data to lower-cost, high-volume storage tiers. Together, SAM and QFS provide a powerful, easily managed, cost-effective way to access, retain, and protect business data over its entire lifecycle.
Stored metadata improves utilization
QFS stores metadata separately from data, improving high-performance RAID cache utilization, reducing access latency, and enabling cost-effective mirroring of metadata.
Built-in striping volume management allows multiple I/O streams to write in parallel across multiple disk systems, increasing bandwidth to sequential applications. What’s more, QFS volumes can scale up to 4 PB.
Faster Write Performance
Reduced bottlenecks
You can tune QFS to meet the application and performance requirements that your environment demands. For example, you can maximize write performance for specific application demands, such as large sequential I/O or small file random access. Direct I/O enables data to be read or written to or from the disk for improved database and random file access performance. This reduces LAN and file-system bottlenecks and improves system performance.
Tuning your system for best results
Setting a single DAU size between 16K and 64 MB, or dual DAUs of 4 KB/16 KB, 4 KB/32 KB, or 4 KB/64 KB lets you tune overall system performance for millions of small files and large systems with ultra-large files. Storage devices can be striped individually or in device groups, making it possible for files to written to and read from a specific device or group. This delivers better and more predictable performance for specific applications.
Reduced Storage Costs
Consolidate and save
The QFS shared environment enables to consolidate your data into one file system, simplifying management and providing a better return on your storage investments. Multiple users can then transparently share the same files, reducing overall storage space consumption. QFS also eliminates the need to mount and re-synchronize file systems when your environment needs to scale to multiple terabytes, simplifying administration.
Web-based management keeps it simple
The QFS Web-based management portal enables your administrators to remotely and securely manage multiple QFS servers, reducing management cost and complexity. This provides you with more control of your storage environment, lowering TCO and improving your return on your investments.
RAC and Solaris Cluster support improves availability
The shared QFS file system provides excellent support and scalability for an Oracle RAC solution. Plus, you can add Solaris Cluster for high availability. QFS lowers your cost of ownership by dramatically reducing the database administration workload in clustered environments over native RAC implementation. Solaris Cluster support of QFS high availability allows you to automate failover of a QFS standalone file system, improving availability.
SAM helps you save
Working in conjunction with QFS, Sun StorageTek Storage Archive Manager (SAM) reduces cost and complexity by automating data management and movement across tiered storage based on its business value over time. This helps you protect and manage your data in a shared access environment.
