With Silver Peak, WAN performance is no longer an obstacle to successful disaster recovery. The SIlver Peak solution cost effectively scales to support large data center environments, delivering LAN-like performance under the heaviest load. Only Silver Peak performs advanced data reduction on both TCP and UDP traffic, improving data transfer times and maximizing WAN efficiency across all disaster recovery applications. This enables enterprises to achieve the following benefits:
Reduce Recovery Time Objectives (RTO)
Shrink Recovery Point Objectives (RPO)
Increase geographic distances between data centers.
WAN Challenges
Disaster recovery can be particularly difficult to achieve across a Wide Area Network (WAN). This is primarily due to the following:
Whereas backups are often performed by transferring incremental pieces of data across the WAN, disaster recovery typically involves the transfer of entire volumes of data. This can require a significant amount of WAN bandwidth.
Down-time means loss of productivity and/or loss of revenue. Recovery must be handled as expeditiously as possible to minimize the costs associated with equipment or network failure.
Silver Peak minimizes downtime
Silver Peak increases the performance and reliability of disaster recovery by delivering the following functionality:
Silver Peak’s Network Memory recognizes repetitive information and delivers it locally. In addition, silver Peak provides enhancements to accelerate TCP and CIFS, reducing the impact of latency on data transfers.
Network Memory can reduce as much as 99% of WAN traffic by eliminating the transfer of duplicate information. Network memory fingerprints at the byte level, enabling Silver Peak to detect and eliminate repetitive patterns even when the backup/replication solution is performing similar functions at the block level.
In addition, Silver Peak leverages advanced compression techniques to further reduce the amount of WAN bandwidth required for backup and replication.
Silver Peak reduces the impact of both packet loss and jitter that occurs when router links are oversubscribed and drop or re-order packets. Adaptive Forward Error Correction (FEC) for example, can reduce effective packet loss by an order of magnitude.
Silver Peak NX appliances use hardware-based AES encryption to protect network traffic and local content, ensuring that all data is protected from unauthorized access at all times.
Silver Peak can support a full 500 Mbps WAN capacity in a single NX appliance, with several variants available that support over 45 Mbps. This enables enterprises to cost effectively support data center to data center links, as well as network-based backups across many remote locations
Silver Peak’s WAN acceleration minimizes downtime when enterprises need it most, making it an essential component to successful disaster recovery.
