Microsoft has released a paper titled:"Achieving Over 1-Million IOPS from Hyper-V VMs in a Scale-Out File Server Cluster Using Windows Server 2012 R2". The paper which contains 24 pages demonstrates the high-performance storage and virtualization capabilities for a Hyper-V virtualized application using the Scale-Out File Server platform in Windows Server 2012 R2.
The platform uses industry standard servers, disks, and JBOD enclosures. With the block storage made available through Storage Spaces combined with the Scale-Out File Server in a failover cluster, Microsoft can deliver extremely high levels of storage performance and resiliency similar to a traditional SAN using Microsoft Storage Solution and inexpensive shared Direct Attached Storage.
The results demonstrate the levels of storage performance that can be achieved from virtual machines running Hyper-V a single Scale-Out File Server using shared Storage Spaces:
- 1.1 million IOPS for 8 KB random reads
- 700K IOPS for 8 KB random writes
- 100 Gbps aggregate read bandwidth
- 92 Gbps aggregate write bandwidth
