Symantec Volume Replicator

Accelerate Veritas Volume Replicator over the WAN

Data protection is an essential part of business continuity and disaster recovery. Data replication is an automated process of sending a complete copy of a set of data for storage at a different facility, and is a key component any data protection plan. 

Symantec Volume Replicator (VVR) is an optional software package from Symantec that runs on top of their Veritas Volume Manager software. It offers continuous data replication over IP networks enabling rapid recovery of critical applications

The WAN link can severely limit VVR replication performance. When the WAN has limited bandwidth, packet loss, out-of-order packets, or high latency, synchronous replication can fail.

How Silver Peak can help

Silver Peak Replication Acceleration software fixes the problems that exist on the WAN, enabling more data to be backed up, in less time, and over longer distances. Silver Peak software solves WAN problems by repairing dropped and out-of-order packets, overcoming the effects of latency, and providing real-time deduplication and compression of all data sent across the WAN. Silver Peak also provides an IPsec AES-256 site-to-site VPN that secures backup traffic without impacting performance.

Once deployed, Silver Peak software is easy to monitor and manage.  Reports are in storage-friendly terms showing the data throughput across the WAN in bytes. Storage traffic is segmented by application, such as replication and or backup. Reporting includes minute, hour, and daily intervals, and includes a 10 day chart to reflect performance data before and after any changes made during the weekend.

When the problems on the WAN have been repaired, it is easy to meet, maintain, and even reduce Symantec VVR’s RPOs.


Customer success story


  • Network bandwidth: (45 Mbps), IPsec VPN
  • Average replication throughput: 25 Mbps
  • Latency: 60 ms
  • Rate of packet loss: ~1%
  • Data set: 300 GB
  • Time to replicate: >24 hours

Silver Peak Results

  • Throughput: 250-300 Mbps  (10x improvement)
  • 15 minute RTO maintained
  • 90% improvement in bandwidth utilization                                                                                     

A leading supplier of business management software and services to 5 million customers worldwide. This enterprise’s network consists of a DS-3 with over 60ms of latency across an IPSec VPN. Prior to using Silver Peak replication acceleration, this network was getting 25 Mbps average throughput (with standard data transfer sizes of 300GB). 

By adding Silver Peak, this customer’s VVR application consistently achieved 250-300 Mbps of throughput, maintained its Recovery Time Objective (RTO) of 15 minutes, while improving bandwidth utilization by 90%. Silver Peak reduced the amount of total data traversing the WAN and significantly shortened the amount of time it took to backup all of the customer’s volumes of data.  By minimizing the company’s risk of exposure, Silver Peak became a critical component of this enterprise’s business continuity plans.
