Organizations have become deeply dependent on their IT infrastructure and critical data for both day-to-day operations and business success. At the same time, risks affecting business continuity have increased, due to Internet-based attacks, natural disasters, geo-political insecurity, or failure of some critical aspect of increasingly complex IT infrastructure. Recent studies show that more than 60 percent of companies do not have a Disaster Recovery (DR) plan and 40 percent of those who do believe it would not be very effective in case of a serious disaster.
Traditional approaches to disaster recovery that involve offsite tape-based backups are both ineffective and unrealistic. Given the increasingly digital nature of business, more data is being generated than ever before. Tape-based methods can’t keep up, and organizations can’t accept prolonged downtimes. Newer approaches that automatically replicate data to an offsite datacenter and orchestrate failover and failback are more appropriate for the needs of today’s organizations. However, with the use of legacy storage technologies, this can become too complex and costly for many organizations, resulting in inadequate disaster recovery processes.
HCI eliminates infrastructure complexities and simplifies management and scaling. This modern approach to building scalable infrastructure is ideal for architecting DR infrastructure. It reduces time-to-value, simplifies deployments and management, lowers the total cost, and overcomes many of the limitations inherent in traditional infrastructure approaches. However, careful attention to footprint, total cost and scalability is critical in order to ensure long term success of these deployments.
