Hey Steve (Duplessie)-
I note that you thought I
was 20 years older you. I guess that means that you either think I am pretty
wise (beyond my years) or that I am desperately in need of a better exercise
program – I will assume it’s the former….
Seriously I never heard of
MAN/MAN but that sounds just like DEC. It was too bad that the leadership there
never appreciated the value of good application SW. If so, they would still
exist today but just be called Oracle…
Thanks for Dinner – wait a
minute – I paid.

Many of you wrote to me to
ask if this means that IT is just destined to be a commodity. – It is just the
opposite! The analogy is that people will pay more for something that does the
job in a simple way. We are clearly a long way from that…

People have been blown away
by our Avamar acquisition. I can’t believe the response. It takes about 4
minutes to explain and you can measure the TCO in days – not years. But some
technical folks have been skeptical that we could perform a backup with
de-duplication ratios upward of 300:1. Here is how we do it (directly from Jed
Yueh – Avamar founder):
“Folks are
stumbling over one of the critical differences between EMC’s (Avamar) approach
and the other VTL/target approaches to de-duplication. Our level of de-duplication is a benefit that
target de-duplication solutions simply cannot provide.
At the
target, Avamar provides similar numbers to others for data de-duplication--25:1
to 50:1.But at the source, Avamar gets up to 300:1 on a daily basis, because we
stop the avalanche of full and incremental backups before it forms, reducing
backup times, client resource consumption, and network utilization.
While most
other systems wait for a 100% full backup to come to its repository before
de-duplicating, Avamar typically sends and stores only 0.3% of the data--in a
fraction of the time.
Target
de-duplication solutions also cannot present network-mount views of their data
stores, because the metadata is stored in the backup server--so they can't tap
the potential value in secondary storage. Avamar can unlock that potential
value (break open the piggy bank, so to speak).”
This is really amazing
technology and will start to drive new “Combinatorial ILM” functions that I
will discuss in a future post.
Mark…
