This has been a fasinating read.<div>&nbsp;</div> The theme from above is that regardless of your choice, de-dupe or software based compression when implemented in a primary storage environment both offer challenges in addition to the benefits.<div>&nbsp;</div> It brings me to mention a relatively new technology called Storewiz.<div>&nbsp;</div> Its an in-band compression appliance for Netapp and Celerra. It sits on the Gig-E fabric and performs the compression before the data is written to disk, delivering massive capacity savings with no performance degredation (yes really). When the data is read, it passes back through the device on its way to the LAN and gets uncompressed on the fly, difficult to believe but this actually improves Oracle / SQL response times from storage.<div>&nbsp;</div> This has been independently tested and verified.<div>&nbsp;</div> The solution is transparent to the hosts, storage and network. Only the payload is subject to compression, leaving the meta data intact so it supports random access in database environments also.<div>&nbsp;</div> Storewiz are technology partners with Netapp and EMC, their solution is fully supported by both vendors.<div>&nbsp;</div> see for more info.
