Fibre-Channel
is an interface standard for connecting computers to mass storage devices
such as disk drives,
disk arrays and
tape libraries. Developed
more than a decade after SCSI,
which it was intended to replace for high performance applications, the
Fibre-Channel standard was specified around faster data throughput speeds, and
longer distances because of its use of fiber-optic cable.
Data reliability
was also significantly better than parallel SCSI because data errors due to
crosstalk and line reflections were effectively designed out.
The
differences in spelling (Fibre in this standard versus Fiber in
the cable) were done deliberately by the standard creators.
In recent
years, new versions of SCSI, such as
iSCSI have nearly caught
up in speed terms (and iSCSI over
InfiniBand is even
faster) so the original performance differences are now blurred. ...from

| Multiple
Vendors Announce Support for FCoE |
ditor:- April 11, 2008 - this
week Emulex
and Intel
launched 10Gb/s Fibre
Channel over Ethernet (FCoE) adapters.
Emulex explained the
thinking behind this. With FCoE, customers may now leverage the ubiquity of
Ethernet to converge both storage and networking traffic, improve overall
efficiency and simplify the infrastructure. Designed to natively transport Fibre
Channel traffic over the Ethernet network, FCoE will take advantage of lossless
Ethernet in the data center. A lossless Ethernet fabric provides the level of
performance and reliable delivery of data required for enterprise storage
environments.
Intel's PCIe dual port FCoE adapter will be in volume production in
May and will be priced at $799. The entire Intel 10GbE family will have FCoE
support on Red Hat Enterprise Linux by July and on Windows later this year.
FCoE will be a new standard with support from leading storage and
switch oems. The first mention on these news pages was in
October 2007 -
when QLogic unveiled its products.
In theory FCoE may help customers
with an installed base of legacy FC applications reduce costs by moving them
onto Ethernet environments. In practise, as we saw with the long drawn out
birth pangs of the iSCSI
market - tidying up all the loose ends could take many years.
It's Groundhog Day for 8Gbps Fibre Channel
HBAs
COSTA
MESA, Calif - February 6, 2008 - Emulex Corp today announced
availability of its 8Gb/s Fibre Channel host bus adapters.
Designed
to maintain backward compatibility with existing 4Gb/s and 2Gb/s products,
Emulex PCI Express 2.0-based 8Gb/s HBAs enable a seamless transition to
next-generation SANs.

comments:- my first reaction to this was - hadn't I already run a similar
story about QLogic
sampling 8Gbps HBAs last August? Turns out I had. That's why Emulex's white
paper Fact vs. Fiction -

QLogic Samples 8Gbs Fibre Channel
ALISO
VIEJO, Calif - August 8, 2007 - QLogic Corp. today revealed that it
has begun testing its complete portfolio of 8Gbs Fibre Channel switches
and host bus adapters and is readying samples for major OEMs to qualify.
8Gb Fibre Channel doubles the performance of today's 4Gb Fibre
Channel products while maintaining full backward compatibility with the large
installed base of 4Gb and 2Gb solutions. ...QLogic profile,

Squeak!
- the Fastest Solid State Disks
Speed isn't everything, and
it comes at a price. |
But if you do
need the speediest SSD
then wading through the web sites of over 55 current
SSD oems to find a suitable
candidate slows you down.
And the SSD search problem will get even
worse. |
 | |
I predict
there will be over 100 SSD oems in 2008.
I've done the research for
you to save you time. And this page is updated daily from
storage news and direct
inputs from oems. ...read
