In VxRail 7.0.100, we have observed one of the most significant performance gains ever in the VxRail platform, leading to better performance and efficiency for mission-critical workloads, databases, and workload consolidation. We measured gains in various storage operations ranging from RAID 1 sequential reads to RAID 6 random writes. The improvements include up to a 69 percent increase in IOPS (for sequential writes in RAID 6) and 38 percent increase in throughput for random writes in RAID 6 configurations.

vSAN 7.0 U1 provides sweeping improvements. Significant highlights include:

• Considerable performance increases on RAID 5 and RAID 6 compared with previous vSAN versions
• Overall gains that significantly reduce the need to use RAID 1 configurations for many workloads

The following figure captures many of the improvements that we measured, representing IOPS and throughput gains in many types of storage operations on the VxRail platform, from vSAN 7.0 to vSAN 7.0 U1.
