FlashGrid enables extreme performance for Oracle RAC on Azure by using one of the following technologies:
FlashGrid
for Oracle RAC on Azure
Extreme performance configurations
Local SSD
Applications that require very high storage read performance will benefit from using local SSDs with 20 GB/s throughput per node and 2.2M IOPS per node. FlashGrid Read-Local Technology eliminates storage read overhead and makes the full throughput available to your database.
Ls_v2-series VMs have up to 15 TB of local SSD capacity. Additional Premium SSD capacity can be added for larger databases.
FlashGrid Storage Fabric provides mechanisms for ensuring persistence of the data placed on the local SSDs by maintaining a mirrored copy on persistent disks and by automatically reconstructing data in case of a loss of a VM with local SSDs.

Mv2-series VMs
Instances with up to 208 physical cores and up to 11 TB of memory can serve extremely heavy workloads, thus eliminating the need for more complex sharding.

“FlashGrid provides us all elements needed for running our mission-critical Oracle databases in Azure: storage and networking software, deployment automation, and 24×7 support”
