With vSAN ESA and Failures to tolerate set to 1 using RAID-5/6 Erasure Coding, vSAN creates an optimized RAID-5 format based on the number of available fault domains. The documentation states that if five or fewer fault domains are available, ESA lists three components for RAID-5. This corresponds to a 2+1 erasure-coded layout, where two data components and one parity component are created. The stretched-cluster setting affects the site disaster tolerance rule, while the stated Failures to tolerate rule with erasure coding defines the local object protection method. The policy note also states that in a vSAN stretched cluster, the RAID-5/6 erasure coding failure tolerance method applies to the Site disaster tolerance setting. Given the answer choices, the ESA optimized RAID-5 component layout that matches FTT=1 erasure coding is three components. One or two components would not provide erasure-coded protection, and four components represents a generic RAID-5 fault-domain requirement rather than the ESA optimized component count shown in placement details.
