EqualLogic HIT 3.4.0 EqlXcp command
June 28th, 2010The EqlXcp utility accelerates and offloads file copy operations from a Windows Server to the EqualLogic Array by using SCSI Extended Copy commands.
Scenario when using EqlXcp:
You are moving large files, like .VHDs, from one EqualLogic Volume to another EqualLogic Volume.
The following is an example of my testing of the new EqlXcp command.
– Physical Server running Windows Server 2008
– Drive E: is a 100GB EqualLogic Volume
– Drive F: is a 100GB EqualLogic Volume
– I have a 4GB file named BigFile.zip
– BigFile.zip is on Drive E: and I want to copy this file to Drive F:
Using EqlXcp and the Copy command below:
When using the Copy command you will see that the 2 NICs for SAN are running around 50% utilization below:
When using the EqlXcp command, there is NO utilization at all through the 2 NICs for SAN because the EqualLogic Array is physically doing all of the work.
Time it takes to copy a 4GB file from Drive E: to Drive F:
– Using EqlXcp: approx 35 seconds
– Using Copy command approx 2 minutes
Needless to say, if you have a large amount of files to move or large files to move from one EqualLogic Volume to another EqualLogic Volume using Windows Server, EqlXcp is the way to go!
NOTE: For more information on EqlXcp, please refer to Chapter 7 in the HIT 3.4.0 User Guide.
Is this executable available for download? If not, how do I install it on the server where the volumes are mounted?
