I just read the blogs from Chris Mellor from the Register
and Tom Trainer Network Computing and thought how insightful are these two
outsiders about the inner workings of IBM.
First off, yes IBM is no longer selling the DCS9900, a DDN
OEM rebranded system in the very large IBM storage portfolio. There is no question that this product is no
longer available after the October 15 date.
Second, the DCS 3700 is already part of our portfolio and is
now an OEM box from Netapp/Engenio/LSI. The density of this system is the same as the
DCS 9900 and makes sense to use the DCS 3700 as a replacement for the DCS9900.
Third, Tom’s blog about SONAS being a monolithic NAS storage
is very skewed. SONAS is a very flexible
in the way we can scale both storage and the throughput with out affecting either
variable. Most “scale out” systems you
have to scale both in order to keep up with demand. SONAS uses some of the best technology on the
market with a huge amount of throughput.
His statement about IBM dropping DDN from SONAS is un-true
and goes to show how much research Tom put into writing this blog. I am sure Tom is looking out to write a
non-biased blog for Network Computing but maybe those days at HDS are still
making a big influence in his ability to look at announcement letter and make a
extrapolations about other products.
Finally, If HDS thought BlueArc was so great, why didn’t they
buy them back when they could have gotten the company for a better deal? Has the product changed THAT much since
2006?I wish HDS only the best for
dealing with the transition and getting that product under the HDS umbrella.
If you do your homework and base your assumptions on facts
instead of conjecture, you will find SONAS is a solid platform in the enterprise
NAS market.SONAS has proven it can be
the market leader with a low cost to performance ratio and will only get better
as time goes on.
Labor day has come and gone and so has all of the holidays
between now and Thanksgiving. This is
only augmented with the hope that your favorite football team (both American football
and what we call Soccer) has a great weekend match and you get to celebrate
with the beverage of your choice.
During your work-week, which can and sometimes does include
weekends, all you hear is no more money to do the things you have to do to keep
the business running. If you have kept
up with squeezing more out your systems with virtualization that’s great but
your network is now overtaxed. The staff
that used to take care of certain aspects of the day to day running of your
data center has been let go and their job has been ‘given’ to you with no
thought of compensating you for the extra tasks.
The Earth is warming, the weather is out of control and the
price of gas is so high that you decide to bike to work to help save the
planet. You spend more time on the road
commuting and look like you need a shower when you get to work after dodging
traffic all morning. Your coffee is
priced higher now because the coffee house wants to use Fair Trade coffee from
farmers in a county you have never been. And your dog is on anti-depressing meds because
you are not home as much and he can’t go out in the yard because of the killer bees
migrating north from Mexico.
Our lives seem to be getting more complicated and it’s nice
when we find things that not only help us but are easy to use.When you
come across these items they make such an impression that you like to tell others
about your great fortunes. I came by a
solution that was very easy to use and the value was so great that at first I
didn’t believe the whole story.
About a year ago, I was asked to help out on the Storewize/Real
Time Compression (RTC) team as it transitioned into the IBM portfolio. I met with the engineers and sales people and
all had wonderful things to say about the technology. I listened but was hesitant
to drink all of the kool aid they were pouring.
A year later I am very much a believer of the RTC technology
and think it really could be a game changer in the market. If you keep up with IDC, Gartner and the other
analyst, they all point to compression of the data as being one of the larger
items for handling future growth.There are a lot of vendors that claim they can
compress data but it’s not all done the same.
One of the things that stood out from day one is the idea of
using LZ compression in real time to compress data instead of deduplication. Coming from a N series (*Netapp) background I
understood how deduplication works and where it was useful. But this was compression which is a different
ball game.Now we are able to shrink the
storage footprint that wasn’t exactly the same as before. Given that Netapp has issues with block size
and offsets, this is exactly what is needed in the market.
The next question I always get and one I had was “That’s
great, you can compress data with the best, but whats the overhead?”. I waited a long time to see what the
performance numbers were going to be and found an astonishing outcome.The RTC appliance made a performance
improvement on the overall solution.It
does help by adding cache and adding processing to the serving of data but it
also improves the performance of the system by having to process less data.
For example, if a system has to save 100GB of data with no
compression, then all of the data has to be laid out on the disk, that sping
for 100GB of data, cache, CPUs, I/O ports all have to work harder to save 100GB
of data.But if we get 2:1 or 3:1 compression ratios,
then all of the components have to work less. No longer are they working to save 100GB of
data but 50GB or 25GB or data. This
allows the system to process more data and have cycles to respond quicker to
I/O requests (IE lower latency).
So the final thing is always the question of how hard is
this to install. Is there a period of
time that you have to wait or have 5 IBM technicians to install it. All I have to say is its easy.So easy that there is a good YouTube video
that goes through the entire process of unpacking to racking to compressing
data. I think the video speaks for
