Derek Seaman posted in his blog yesterday about capacity thinning, zero reclamation technologies and included a test of 3PAR's Thin Persistence software. In his post he lists the steps he took to run the test, including the setup and final results. Please go read what he wrote, but I thought I'd post his summary:
This test proved that the 3PAR zero reclaim feature worked as advertised, happens in real time, and take very little effort to use. The same process would work for a virtual machine as well. If I was using the Veritas Storage Foundation I would not have to use the sdelete command and it would be fully automated. Hopefully they will work with Microsoft and VMware to support a fully automatic and native method to reclaim the deleted space. Until then, you can run sdelete from time to time to drop those extra pounds from your fat LUNs.
3PAR sees thinning technology as a strategic advantage that we are committed to advancing in the industry with software partnerships. Examples of progress on these fronts include the automated thinning for Oracle ASM and implementing VMware's VAAI Block Zeroing, which turns a thick volume into a thin one on 3PAR storage with Thin Persistence.
