Summary

The improved performance of solid-state arrays is causing IT departments to change their business continuity implementations because network delay becomes a bottleneck when SSAs are implemented. This research describes what I&O leaders must do to change their disaster recovery processes.

Impacts and Recommendations

  • Applications and services that require low-latency storage and high availability cannot provide business continuity at distances farther than internal data centers, prompting I&O leaders to redesign DR infrastructures
  • The order of magnitude improvement provided by SSA response times highlights to I&O leaders that any replication method used by any other low-latency device will be affected by increased network latency delays and limitations
  • High-performance applications and services need to use methods other than synchronous storage array replication to achieve high availability, therefore I&O leaders must look for new technologies to achieve business continuity
