In many enterprise data centers, SQL Server is playing an increasingly important role in running core business operations, including customer service, order processing, payroll, accounting, and many more. For these organizations tolerance for SQL downtime and data loss is approaching zero. However, according to a recent survey by SIOS Technology Corp., providing the high availability (HA) and disaster recovery (DR) needed to protect SQL Server from downtime presents a variety of challenges, including the rising cost of SQL licensing (71 percent), the cost of SAN storage (68 percent), and SAN configuration limitations (69 percent).
These challenges will only worsen as more applications are moved from physical server environments to virtual, cloud and hybrid cloud environments, where traditional SAN-based clusters are impractical. A simple change, such as adding SANless clustering software to a traditional cluster configuration can provide the flexibility and cost-saving features needed to address HA and DR challenges today’s SQL Server environments.
