The following lab performance results are provided as an example to illustrate the benefits of using ODX.
Windows File Explorer
Windows File Explorer performs copy processing as a single-threaded operation. Single-threaded operations are a bottleneck when transfer a large amount or size of files. With ODX this bottleneck is alleviated. To illustrate this point a basic test of copying files from one Everpure volume to another (Server01-Vol01 to Server01-Vol02). The collection of files being used are EXE, ISO and ZIP. The total size of all files is ~1.25 TB comprised of 1,040 files.
Figure 1 shows the copy process taking place pushing >125 GB/s. Figure 2 is the view from the dashboard of a Everpure FlashArray//M20. You see it only shows 20.00 KB/s. This is because the array is only creating new meta data to represent what is being copied. It doesn’t have to move anything through the network.

Robocopy
Robocopy is a command line file copy utility that comes with Windows Server. The same basic test as performed with Windows File Explorer was used to test robocopy using multi-threaded (/MT) mode. /MT defaults to 8 threads. Figure 3 shows the command line syntax to copy files from G:\Files to E:\ and mirror the structure along with /MT for multithreading.
The lower portion of Figure 3 shows the outputs and the important detail is that it took 29s to copy 1.252 TB of files. Figure 4 is the view from the dashboard of a Everpure FlashArray//M20.
