IT Dog getting down and dirty today because that’s what it is going to
take to deal with the dirty world of “vendor lock-in.” There is
really no way to dress this up and make it smell nice because it just stinks
and although I would roll in something this nasty down at the dog park, I
wouldn’t want you to have to live with the smell.
I read an excellent article by Chris Mellor at The Register discussing the
need to develop a standard for the server flash-storage array interface and
it really got me thinking about the vendor lock in issue.
“What is EMC up to with Project Lightning?”
We all are kind of waiting to find that out now aren’t we? EMC
announced Project Lightning as their foray into the server side flash
business, putting it sites on the nice people at FusionI/O, STEC and others.
I am wagging my tail to see EMC recogn... (more)
File System Alignment for SSDs
There are many techniques and methods that can be used to tune an IT system
to improve overall system performance. SSD caching is widely being used as
a low cost, easy to implement method to quickly increase performance with
little or no impact on existing operations. One thing that needs to be
considered when choosing SSD caching is how to configure a file system to
maximize the performance increase SSD caching provides.
Operating Systems and Block Size
In the past few years, the sector size of HDDs has increased from 512 bytes
to 4k bytes. Relat... (more)
Hey there; the IT Dog back with some color commentary on our VDI experience.
When I first heard the name, I thought VDI was the latest model Volkswagen
diesel, but as the guy with the suit explained in the last blog, VDI is
Virtual Desktop Infrastructure. Now that you know what VDI means, I am sure
you know all there is to know about it, right? Well, I wish it was that
easy for me.
Where Do I Begin?
I guess I’ll start from the beginning. At my company, my IT guys were at
their wits end trying to manage the 1000 or so desktops, spread out over four
different locations, with va... (more)
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.

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)
