|aligning database block
sizes with SSDs|
Editor:- February 5, 2013 - I often hear from
software for SSDs who
- having researched the subject of
flash etc - have
spent too much time over-worrying about internal SSD hardware details that
they really shouldn't be worrying about. Because by the time they learn about
such things - that type of hardware anxiety is ancient history.
I came across a recent blog by Chas. Dye at Pure Storage
DON'T Fiddle with Your Database Block Size! - which also warns about this
Chas says - "At Pure Storage, we believe that a factor
that should never influence the block size decision is your storage subsystem."
comments:- I'd certainly agree that trying to slavishly make your data
structures look like something you've read about which might be inside an
SSD controller is
probably a waste of time - because unless you know the SSD designer you don't
really know what's going on - and the abstraction you read about in some web
site is only a small part of the picture.
SSD is so sensitive to
the data you hit it with - it's not the SSD you should have bought in the
Skyera says GbE switches inside SSD save costs

GbE switches inside its SSD racks - so you don't need so many outside.
Nutanix has a new NFS for PCIe SSD accelerated CPUs
June 12, 2012 - Nutanix
announced the general availability of NDFS (Nutanix Distributed File
System), a bold new distributed filesystem that has been optimized to leverage
localized low latency PCIe
SSDs such as those from Fusion-io.
shifting the NFS datapath away from the network directly onto the VMware vSphere
host, NDFS bypasses network communications that have historically been fraught
with multiple high-latency hops between top-of-rack and end-of-row switches.
Nutanix accelerates both read and writes for any workload.

NetApp acquires Engenio
Editor:- March 9, 2011 -
announced that it has entered into a definitive agreement to purchase the Engenio external
storage systems business of LSI for $480 million.
The close is anticipated to occur in approximately 60 days subject to
customary closing conditions.
Engenio will enable NetApp to address
emerging and fast-growing market segments such as
full-motion video capture and digital video surveillance, as well as high
performance computing applications, such as genomics sequencing and scientific
research. NetApp has the channel reach and customer relationships today that
require high performance and big bandwidth capabilities that will be well served
by Engenio's storage platform. NetApp says these segments are expected to
collectively represent a $5
billion incremental market opportunity by 2014.
comments:- LSI has been trying to sell off Engenio since 2004. NetApp will
love them more. For a brief time this past week - searches for Engenio exceeded
that for "SSD". In the previous decade over
500 leading storage
companies were acquired, changed name or went bust.
