HyperIP WAN Optimization Virtual Appliance Solves Key Network Issues for Dell EqualLogic Replication
Posted by Marketing
A customer was recently experiencing slow replication of their databases using a Dell EqualLogic Replication application from their iSCSI SAN. They were concerned about replication windows so decided to research performance on the Dell website. In their investigation they found the following document on the Dell website.
Using Dell EqualLogic Auto Replication
This document explains use case scenarios and various configuration issues of Dell EqualLogic Replication in a typical DR scenario. A couple of the main network considerations when implementing Dell EqualLogic Auto Replication should be bandwidth and latency of the circuit. In high latency connections, replication will still work, but allow more time to complete. This is sound advice. From our experience, packet loss can also have a huge impact on application throughput.
HyperIP WAN Optimization virtual appliance, when configured with EqualLogic Replication, can reduce bandwidth requirements for replication by over 50% while maintaining high throughput. This brings the windows for replication into minutes instead of hours, allowing for the ease of testing the recovery plan, as well as recovering a node, server, cluster, or the entire site’s data volumes after a true disaster.
Simply, your current benchmark or replication assessment must take into consideration the average available bandwidth on a link with any packet loss or latency can be reduced to 40%-60%. HyperIP accelerates applications over WANs by time of day, to nearly 95% utilization. With a combination of block level compression, latency and packet loss mitigation, HyperIP can then improve EqualLogic replication throughput by 3X-6X .
