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 am calling a “cache diet” (no, not the
“crash diet” you went on last year to lose a few lbs). You may think
your cache diet is great. “Dog, we got some performance improvement and
the applications guys are not bothering me anymore, at least for now.”
And it is true, you did see some perfor... (more)
This blog starts a series of blogs we will post regarding Virtual Desktop
Infrastructure or VDI. To directly quote wikipedia "VDI is a
desktop-centric service that hosts user's desktop environments on remote
servers and/or blade PCs, which are accessed over a network using a remote
display protocol." Basically, VDI means a user can access their desktop
from any terminal device capable of running the remote display protocol.
Further, VDI runs a complete implementation of a typical desktop OS (e.g.,
Windows XP, Windows 7, etc.) as a virtual machine on the host server. There

Virtualization has been used for many years to maximize the usage and value
of installed server hardware. It allows resource sharing of single computer
among many users through virtual machines (VM) that are securely isolated and
highly reliable. In recent years, companies like VMware has been extremely
successful in deploying virtualization products to help many existing IT
installations increase performance without physically increasing their
hardware investment. One disadvantage of a virtualized environment however is
the traditional primary storage architectures were not desi... (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)

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.
