In general, it is recommended to use fewer storage pools within Dell Unity XT arrays because this reduces complexity and increases flexibility. Dell Technologies recommends using a single virtual disk pool when implementing SQL Server. This provides better performance by leveraging the aggregate I/O bandwidth of all disks to service I/O requests from SQL Server. A single drive pool is also easier to manage, allowing an administrator to quickly and easily adapt the storage system to satisfy the ever-changing workloads that are common in SQL Server environments. Before creating multiple storage pools to separate workloads, understand the various Dell Unity XT features that are available for managing and throttling specific workloads.
