Do disk based VTLs draw less power than tape?

The tape is dead debates rage on as they have for a decades which make for good press and discussion or debate during slow times, similar to coverage of what Britney Spears or Paris Hilton are or are not wearing.

In the on-going debates and Greenwashing of what technology or vendor is greener to prevent global warming, some recent tape is dead flare-ups have occurred including one hinting that tape libraries can draw more power than a disk based VTL with de-dupe are discussed over on Tony Pearson of IBM fame blog site as well as Beth Pariseau of TechTarget StorageSoup site. I posted some comments on those sites along along with a link to a StorageIO Industry Trends and Perspective report titled "Energy Savings without Performance Compromise" as an example (look for an updated version of the comparison charts in the report in the not so distant future). The report looks at how different storage tiers including on-line disk, MAID, MAID 2.0 and tape libraries vary to address different PCFE (power, cooling, floor-space, environment) issues while supporting various service levels including performance, availability, capacity and energy use.

Additional related material can be found at storageio dot com including the Industry Trends and Perspective Report Business "Benefits of Data Footprint Reduction� in general covering archiving, compression (on-line and off-line) along with de-duplication

Re: Global Moderators - [quote:1l1khqcw]In granting global permissions, my only reservation falls back to the concern of being too quick on the draw to ban a suspicious member[/quote:1l1khqcw] You and Evan would still be the only ones with that power. I don't have banning or other admin powers at any of the other forums I moderate even though I am a global moderator.

Women Entrepreneur Tips - Thank you LeoOliveros, I found #4 particularly true in my case: 4. The Enterprise Must Include the Power of Power Networks. As a conductor of your own enterprise, you can not see yourself as a one-woman-show. You must choose to utilize the power people in your life, by asking for help when you need it, and effectively delegating in order to capitalize on your strengths and that of your power network. When certain experts are not represented in your power network, you must actively seek advisors or mentors and develop a team of specialists, so the benefits are received by everyone involved in the power network - the true Power of Power Networks.
Re: Suspicious/Problematic Users - Hi Trent, Well done on your diligence but I was not fooled at all. The first post I saw seemed harmless enough although off topic so I replied. It was because I was suspicious that I checked out her other two posts and based on those, I tried to report them but David was on the ball and had done that already. I advised her to get out of our forum as she is in the wrong place as you will see. As we don't have the power to remove posts I left that to GT, cheers, Mal.
Euphemism for lawyer? - [quote:2irdstnl]It is also key to have a qualified person draw up a contract for any agreement. [/quote:2irdstnl] Much as I dislike lawyers, it's a qualified laywer you need to draw up a contract for any agreement. Would anyone else be qualified to draw up a contract? I only ask because the phrase "a qualified person" makes it seem like there is someone other than a lawyer who can do this?
