| Stealth
mode startup wakes petabyte SSD appliance market |
Editor:- October 17, 2016 -
Exabyte SSD Appliance emerged
from stealth mode and today
announced a $400
million series C
funding round and
immediate availability of its new Paranoid S3B series - a 2U entry level
Solid State Backup appliance
with 1PB (uncompressed) capacity.
Sustainable sequential R/W speeds
are 12GB/s, random performance is 400K IOPS (MB blocks). Latency is 10
microseconds (for accesses to awake blocks) and 20 milli-seconds (for data
accesses to blocks in sleep mode.) ...read more | | |

Serial Attached SCSI: New
Interface, New Storage Rack? - article by Terabytes Server Storage Tech
Users
will need more than just host bus adapters and
disk drives to deploy
the new
Serial Attached SCSI
technology. But the traditional way of designing the backplanes in storage
racks could lead to high cost and not use the expansion and high availability
aspects of SAS to best advantage. In this article one of the world's leading
suppliers of computer chassis describes their award winning new backplane
concept which gets the best out of the new SAS technology while reducing costs.

Rackmount Storage - from Obscurity to Popularity |
Rackmount storage is one of
the most popular and fastest growing segments in the storage industry today, but
it was not always so.
Rackmount computer systems started to appear
in the mid 1970's powered by the 8 bit microprocessor revolution which was
quietly reshaping the computer landscape. My first job in 1977 was building a
real-time training simulator which used a proprietary rackmount computer from a
long forgotten (Signetics) processor. In the mark 2 version we improved things
by putting in a 2nd (Intel) processor. There were no operating systems in those
days. To get the real usable speed out of 8 bit micros, you wrote everything in
assembler and changed tasks by interrupts. By the late 1970's you could get "standard"
rackmount computers from Intel using Multibus, and a real operating system
called RMX.
In the 1980's VMEbus became the new standard for high performance
rackmount systems, in which you could get every type of processor upto and
including SPARC and SunOS. The high end systems I worked on for military and
other research applications typically had multiple processors running different
operating systems in the same backplane, which for a techie - was great fun. For
low end systems the company I worked for sold rackmount PCs with passive
backplanes from companies like Qualogy. Industrial PCs became popular because
they replaced proprietary computers running SCADA (Supervisory Control And Data
Acquisition) which oversaw networks of programmable controllers in car
factories, bottling plants and wire manufacture. SCADA was also used to control
process controllers in industries like chemicals, oil and brewing.
But
outside the industrial, communications, or military markets or a computer R&D
environment the average user was unlikely to encounter a rackmount computer
in an "hands on" way right upto the mid 1990s. Then the internet, and
particularly the web changed everything.
As editor of the Sun
Microsystems buyers guide, called the
SPARC Product Directory, I
noted that rackmount
SPARC servers had moved from relative obscurity to the #1 most popular
product slot visited by readers in 1999. That's because it was more economic to
implement ecommerce transactions using server farms built from networked
rackmount systems than using single monolithic Sun mainframes which cost
several times more.
The same phenomenom was happening in the Wintel
world. Research company IDC reported that throughout the US IT recession in 2000
and 2001, shipments of rack optimised servers continued high double digit growth
rates. This was also commented on in Dell's own financial reports. It wasn't
long before storage vendors started noticing that their rackmount tape drives,
RAID systems etc were growing at a much faster rate than anything else they were
selling.
I expect that rackmount servers and storage will become the
dominant form factor for enterprise installations. Rackmount takes up less floor
space. It's physically more secure than isolated boxes, and it's cheaper to
maintain. In fact on this web site, STORAGEsearch.com,
most of the systems images featured in ads and in news stories have been
rackmount for the last couple of years.
The products featured on this
page are only a small proportion of the thousands of rackmount products from
hundreds of manufacturers that you can find on this site. Rackmount Storage is
the way of the present and the form factor of the future. | |
