the need to
interconnect different storage interface devices
by Zsolt Kerekes,

Back in the old days of
there were even more interfaces than there are today - because there were less
industry standards and more
So interconnecting systems was complicated and the
storage router market was fragmented as specialist firms operated in different
market niches and rarely competed head to head.
It's still complicated
today - but mostly network
storage architecture hasn't changed much in the past 10 years - since the
end of the dotcom boom which ensured that every organization had to own ethernet
compatible storage - even if internally its used a mish mash of disparate
What has changed instead are the speeds and differing
roles of fibre-channel SANs,
GbE NAS, and
iSCSI and the
introduction of a new storage network standard called
InfiniBand which is
the only completely new transport which appeared in the decade 2000 to 2010.
Another thing which has changed in storage infrastructure is the DAS
connections. Good old parallel
SCSI has been superceded by
Hard drives still spin at
RPM speeds as they did 10 years ago, But their capacities have got bigger.
thing which has changed a lot is the way
backups are done.
Tape libraries - which
dominated network backup thinking in the 1990s - have mostly given way to
disk backup. The transition
to VTLs is documented in another
SSDs haven't changed the storage router market much - but
One of the earliest volume uses of embedded SSD
accelerators (outside the military
market) was the use of 3.5"
SSDs inside storage routers in 2002.
Looking ahead to the future

As we progress to that point (from 2011) storage
architectures could get very messy as users leverage point products such as
PCIe SSDs and
SSD ASAPs to get

systems they already own.
I'll be reporting on progress in that area as
usual in storage news.

It will replace the
last remaining strongholds of
hard drives in the
datacenter due to its unique combination of characteristics, low running costs
and operational advantages.

By that I mean how big was the mental map? - not how many
inches wide is the SSD.
The novel and the short story both have their
place in literature and the pages look exactly the same. But you know from
experience which works best in different situations and why.

in the designer's mind. Even if they didn't think about it that way at the time.
