I have been trying to confirm that Iometer supports disks larger than 2.2TB, but it does not seem to be working.

I have written a pattern to specific LBA's above 2.2TB and when I put the LBA into the Disk Starting Sector field in the Iometer GUI and perform a sequential write I would expect the pattern to be overwritten, but this is not the case. For LBA's below 2TB this works, but not above 2TB. I have tried this with the 2008 version and the RC1.1 version, both 32bit and 64bit on a Windows 2003 64bit server installation, and neither seem to work above 2TB.

Does the Disk Starting Sector field accept LBA's larger than 2TB?

    I should also state that the LBA ranges I'm looking at are '4613734300' (roughly 2.2TB), and '5859375000' (roughly 3TB). Iometer cannot write to these LBA's

     
  • Hi, Could you please confirm that this happens with both sequential and random I/O?
