article about PCIe SSDs |
Editor:- July 20, 2010 - DCIG has published an
article -
Identifying
the Right SSD Architecture which describes the thinking behind some
PCIe SSDs - and in
particular those designed by the article's sponsor Fusion-io.
One
of the disadvantages of the Fusion-io architecture (in my view) is that if you
install it into a slow legacy server - it will not give you the same speedup
as some other designs which offload more of their internal housekeeping
functions to an onboard SSD
controller. That difference magnifies if you fit multiple SSDs into the same
PCIe bus.
At the other end of the scale, however, the Fusion-io design
includes future-proofing for the server oems who design it in - because to some
extent the performance will scale upwards automatically when they deploy
the same SSDs into newer faster multi-core CPUs in new models of their
servers.
These very big differences are part of what I call the Legacy
versus New Dynasty segmentation model - which has been happening in the
rackmount SSD market
for several years.
Superficially similar looking products actually
address very different markets - and if you know which side of the divide
you're on (and it can be different sides for different projects in the same
enterprise) that can shortcut your vendor qualification processes. |
