There was an interesting announcement today regarding Permabit who is now providing primary storage optimization through OEMs and having their solution embedded into the storage system. This further drives home the point of where capacity optimization should live. I do have a couple of questions however:

What is the performance like? I see phrases such as “High Performance Data Optimization Software” but don’t see any performance metrics – such as ‘no performance degradation’… Read more »

Today I read a very well written blog by The SANMan. The only issue is, you can't comment on his blog. This is the first technology blog I have seen like this. So, I will have to post my thought here.

In his post "NetApp Takes the "Primary" Lead for Data Reduction" - which seems more like theory and a commercial for NTAP than reality (see comments @… Read more »

Or should I say, ‘Setting the Record Straight on Backing Up Optimized Data’? Carter discusses on this blog they myriad of ways to perform backups on optimized data. (His blog actually reads more like a white paper explaining how backup needs to be configured to work with his product.) One of the ways Carter describes to do backup is via NDMP and says “… is the most complicated.” The funny thing is that this is… Read more »

This video doesn't talk about the merits of one versus the other but how when compression (or capacity optimization is done right) it should enhance data deduplication, not impact it.  Enjoy and for more videos like this one go to the StorwizeChannel. classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" width="580" height="360" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0"
