When deploying a Dual-SP (Storage Processor) Dell Unity VSA (Virtual Storage Appliance), the recommended disk format is Thick Provision Eager Zeroed. This format pre-allocates storage capacity and zeros out all blocks at the time of creation, which ensures better performance and reliability compared to thin provisioning or lazy zeroed formats. This is especially important for high-performance storage environments. Reference:Dell Unity VSA Deployment Guide
