Real-time Compression Example

Thanks to Patrick Lee for this example of Thin Provisioning and Real-time Compression…

  • A 100 GB logical disk  is presented to Microsoft Windows 2008.
  • Win2K8 creates eight 10GB files on the logical disk (the files are very sparse).
  • 100GB of volume space actually consumes 215MB of thin provisioned space.
  • With compression turned on, the consumed space drops to 88 MB.
How much would you save? Get the Comprestimator tool here. You’ll need to sign in with or create an IBM ID. Comprestimator will run on:
  • Red Hat Enterprise Linux Version 5 (64-bit)
  • ESXi 5.0
  • AIX V6.1, V7.1
  • Windows 2003 Server, Windows 2008 Server (32-bit and 64-bit)

Comprestimator will sample your actual data – i.e. provides real estimates, not just marketing promises.

  1. ok I get there are a ot of savings at Storage Level…..but Windows OS stills says spaced used 80GB so basically what’s the deal? If I get this correctly the deal is I can assign more windows boxes to my 100GB from the storage right?
