In summary, here’s how DISKSPD is being invoked:

To skip the Windows cache manager, we specify unbuffered IO ( To saturate performance, we specify 4 threads per file ( , the popular Windows micro-benchmark tool, in hundreds or thousands of Hyper-V virtual machines at once. VM Fleet makes it easy to orchestrate running More precisely, we know that Hyper-V virtual machines typically perform random 4 kB block-aligned IO, so that’s our benchmark of choice. In virtualization and hyper-converged infrastructure, it’s standard to count storage input/output (I/O) operations per second, or “IOPS” – essentially, the number of reads or writes that virtual machines can perform. For databases, you can measure transactions per second (T/s). For example, you can measure the rate of data transfer (GB/s) by simply copying files, although this There are many ways to measure storage performance, depending on the application. The total active working set, accounting for three-way mirror resiliency, is 312 x 10 GiB x 3 = 9.36 TiB, which fits comfortably within the Intel® Optane™ DC persistent memory. For the best performance, every VM runs on the server node that owns the volume where its VHDX file is stored. Each VM runs Windows and is assigned 4 GiB of memory.Įvery VM is assigned one fixed 40 GiB VHDX where it reads and writes to one 10 GiB test file. That’s 312 total Hyper-V Gen 2 VMs across the 12 server nodes. In this case, to saturate performance took 26 virtual machines x 4 virtual processors each = 104 virtual processors. For example, with 2 sockets x 28 cores we’d assign up to 56 virtual processors per server node. Ordinarily we’d create one virtual processor per physical core. To accurately measure IOPS to persistent storage only, the in-memory CSV read cache is disabled. All other settings, like columns and interleave, are default. Each volume uses three-way mirror resiliency, with allocation delimited to three servers. Each volume is 8 TiB, for about 100 TiB of total usable storage. (Specifically, mitigations for Spectre v1 and Meltdown are applied.)īest practice is to create one or two data volumes per server node, so we create 12 volumes with ReFS. The power plan is set to High Performance, and all other settings are default, including applying relevant side-channel mitigations.

Purpose-built for efficiency and performance, they're embedded in the Windows kernel and meticulously optimized. Hyper-V and Storage Spaces Direct in Windows Server 2019 are the foundational hypervisor and software-defined storage of the Microsoft Cloud. To go with the fastest hardware, you need the fastest software. Intel® Optane™ DC persistent memory delivers breakthrough storage performance.
