Solid State Disk (SSD) technology is one of the hottest IT areas in 2012. The
promise to eliminate storage IO bottlenecks and increase application
performance, enable server virtualization, enable data center growth, and
reduce IT costs has prompted 83% of all IT departments to consider SSD. But
those planning an SSD deployment face a variety of deployment choices.
Moreover, choosing poorly can yield large expense, disruption to existing IT
environments, and a complex new set of storage management tasks.
Join Brian Garrett, Vice President at the Enterprise Strategy Group, Inc. and
Peter Velikin from VeloBit, Inc. for a comprehensive overview of the key
considerations you must make when building your SSD strategy. This webinar is
intended to help IT executives make wise decisions. You will see first-hand
research on the actual vs. perceived benefits organi... (more)
Dr Dog Says “You Need More RAM In Your Cache Diet”
Well, I am not really a doctor, but I play one on TV. You may remember (if
you are old enough) that line from the 1986 Vicks-44 TV commercial. Anyway,
while I may not be a real doctor, I can certainly tell you about why you need
more RAM in you cache diet.
“I Think My Cache Diet Is Great”
If you were happily running your IT system but needed some additional
performance, chances are you turned to some kind of SSD caching solution to
improve performance at a lower cost point than adding more servers or
storage. You went on what I a... (more)
After I sold my last company, I looked at dozens of opportunities before
joining Qing Yang in cofounding VeloBit. Many have asked me what made me
choose VeloBit. They are interested in my answer because I was a successful
venture capitalist for 10 years at Bessemer Venture Partners and Flagship
Ventures. As a VC, my job was to pick startups that had the highest chance
for great success – and I was good at it.
So what does a VC look for, and why is VeloBit compelling? In my VC days, I
created a list of questions for evaluating investments. In this note,
I’ll explain ... (more)
Whether ‘tis nobler in the mind to suffer the slings and arrows of your IT
manager or to take up cache against a sea of data. With apologies to Bill
Shakespeare, the IT Dog is discussing two different cache write policies:
write through and write back. Let me take a run at telling you what they are,
why they are different and what you need to think about when you decide what
policy to use.
Cache Write Through
This is the easier to explain and understand of the two policies discussed
here. Cache write through is like having your cake and eating it too. Data is
written into cache ... (more)
While it's conventional wisdom that SSD prices are falling, the reality may
change soon. The DigiTimes reports that the price of NAND flash memory,
which is a large component in SSDs, rose significantly in the second half of
The article attributes the price increase to two reasons. NAND manufacturers
have been intentionally limiting supply, citing Toshiba cutting production by
30%. It also points to higher demand from smartphone vendors.
The NAND manufacturers could be looking at the DRAM business and trying to
avoid the cutthroat price competition that eliminates marg... (more)
