Use SQLIO to Determine IO Channel Throughput
SQLIO is a tool that determines the I/O capacity of a SQL configuration. To predict how well VCM will
function on a particular IO configuration, and to obtain a baseline of how well the IO subsystem functions,
run SQLIO before you install VCM.
After you install SQLIO, configure these SQLIO settings to ensure an accurate report of IO throughput:
n
64K Block Size
n
4 Threads
n
2GB File Size minimum
n
Sequential IO
When executing SQLIO, ensure that you create baseline information for each IO channel (logical disk) that
will be used for VCM data as well testing both Read and Write operations.
Download SQLIO from the Microsoft download site.
