WAFS WAN Optimization
Leverage our unique file-aware WAFS technology to ensure complete data integrity and consistency—even in the event of WAN disruption or equipment failure at the branch office.

protocol limitations.
Uniquely Secure and Accurate
Packeteer's WAFS technology is unlike any other, pulling from its file-aware WAFS foundation to ensure complete data integrity and consistency—even when the WAN is disrupted or branch office equipment breaks down. Other WAFS solutions jump to save operations without maintaining file logs or preventing additional risk.
File and Data Integrity Management
No need to trade off between performance and reliability. Unlike other WAFS products, Packeteer's distributed file system technology incorporates lock manager, journaling and recovery to deliver maximum WAFS performance while protecting remote users from stale data, write collisions, WAN outages and system failures.
File updates made by one user will never conflict with updates made by another. Updated files are always available to all users across the network. All file changes are synchronously logged to persistent storage at the remote office, guaranteeing data integrity during WAN disruptions, power outages and reboots.
How Packeteer WAFS Works
Data is securely held at the branch—with instant access always in synch with the master copy maintained at the data center. Access the local copy to "check" with the master and ensure the local file is up to date. Coherency and integrity is guaranteed and maintained through full management of read/write/lock operations integrated with your file system.
Make terabytes of data available to remote locations while maintaining control and access at the data center, ensuring that data is properly maintained and backed up. Control the amount of disk and storage space required at remote sites by allowing speedy access to ALL centrally located data and locally cached copies of the most used files.
Single-instance Storage
Packeteer's single-instance storage technology ensures that file data is only held at the edge—close to branch office users—with no data mirroring needed at headquarters. No need to double-size the data center, much larger numbers of remote appliances can be deployed against a single server appliance at the data center.
Other WAFS solutions require byte-for-byte matching mirrored at the data center, leading to scalability limits and spiraling costs. Packeteer appliances can be automatically pre-populated at the edge for frequently used data without the need for external agents or applications. Also, IT personnel can pre-position data at the edge—in advance of user request—to spread network traffic more evenly throughout the workday and improve branch office performance.
End-to-End Microsoft Security
Packeteer offers the only solution on the market today that natively supports complete end-to-end CIFS security for maximum protection against hackers and other intrusions. Our WAFS technology incorporates native CIFS technology from Microsoft—future-proofing your technology investment against upcoming protocol changes.
Other WAFS solutions are incompatible with Microsoft end-to-end security policies. Even when these policies are enabled, they fail to perform adequate optimizations over the WAN. Packeteer WAFS integrates natively with these security policies and offers no compromise between performance and security.
Native Microsoft Integration
Incorporating native Microsoft technology, Packeteer WAFS integration seamlessly integrates with technologies such as Active Directory, Kerberos Authentication and CIFS security. Packeteer will continue to leverage Microsoft technology as Microsoft protocols evolve—and substantial revisions are already planned for Windows Vista and Longhorn—rather than relying on reverse engineering or open source projects.
Disaster Recovery (DR) Support
An organization may establish a duplicate secondary data center at another corporate location or business recovery company as part of its business continuity strategy. Packeteer configures this secondary data center with remotely connected and synchronized appliances—ready to take over when disaster strikes.
When the primary data center goes down, normal branch office operations are restored by activating appliances at the secondary data center—transparent to remote appliances and branch office users. Leverage the cached data in the branch office appliances and preserve user performance.
Failover
At the local level, Packeteer failover technology keeps individual appliances highly available at the data center and remote sites. Pair any "critical" appliance with another in an active/passive configuration. The system state and cache are mirrored via a private network connection between the units. When one device fails, the other comes online and transparently takes over—operations continue without manual intervention.
