the
Benefits of SAS (Serial Attached SCSI) for External Subsystems - article by
Adaptec
This introduction to Serial Attached SCSI gives you
an idea of the performance, compatibilities, applications and roadmap for this
new directly attached disk connection standard. With throughput capability
faster than 2Gbps Fibre-channel systems and faster than ultra320 SCSI - the new
SAS products not only provide an upward migration path for parallel SCSI
applications but also open the door to a new class of high performance high
reliability enterprise systems.

Testing
Storage Solutions - article by Extreme Protocol Solutions
In
the data storage industry, testing is generally considered a neccessary evil in
bringing a product to market and as a result often companies will do the bare
minimum neccessary in order to cross the item off its checklist. This article
by Roger Gagnon President / CEO
Extreme Protocol Solutions attempts to explain why testing is so
important to product validation and also to provide a concise methodology to
testing. ...read

the
Dangers of Removable Storage Media - article by Pointsec
In
the early
James
Bond films of the 1960s, viewers were introduced to an array of implausible
(at the time) portable high tech spy gadgets. Nowadays we know from our own
everyday experience that something the size of a cigarette lighter can actually
be a video camera with its own wireless internet access.
The
proliferation of miniature high capacity storage devices creates a serious
problem for commercial and national security. This article provides an up to
date picture of the intrinsic dangers posed by current removable storage
technologies. ...read

Privacy
and Security Regulations - How Do they Impact Storage Systems? - article by
ASNP
What are the legal regulations covering the type of
storage system, backup and disaster recovery and encryption mandated for
companies operating in the US?
This article answers those questions
and is a sound starting point for anyone having the duty of care and
responsibility for their corporate data. Because regulations change so quickly
it's worth considering the impact of these best practises on your own
organisation even if you think you are currently outside the scope of these
laws. That will reduce the level of panic when they creep up on you. ...read the article,,

SCSI -
Small Computer System Interface:- is a high performance parallel interface for
connected mass storage devices such as disk drives to a computer. Originally
specificied using logic level (TTL) signals over ribbon cable to daisy chain
upto 8 devices, this standard has been enhanced over the years to include newer
voltage levels, higher speeds and more devices. The standard enables large
amounts of data to be requested using a small number of intelligent commands.
Dur to the popularity of this standard some manufacturers have developed
extenders which enable connection over a long distance, converters such as IDE
to SCSI, and routers which translate the SCSI interface and commands to fibre
channel compatible signals.
Newer variations such as
Serial Attached SCSI
and Internet SCSI
preserve compatibility at the SCSI driver and command set level, but offer
different connection and routing methods.

Serial Attached SCSI - Delivering Flexibility to the
Data Center - article by LSI Logic and Maxtor
If you think
you already know SAS because you know SATA and traditional SCSI then think
again. Sometimes disruptive technologies wear an unassuming disguise. In
fiction, Clark Kent, Frodo Baggins and Buffy Summers at first seem harmless, but
we see them change into Superman, the Ring Bearer and the Slayer.
SAS
too comes cloaked in plain garb - with a physical layer which looks a lot like
SATA. But like the Incredible Hulk there are muscles rippling under that shirt -
and you would be wrong to dismiss SAS so lightly. There's a lot more inside this
interface than it says on the box as this informative article reveals. ...read the article,

Serial
Attached SCSI - Sound Byte
SAS technology enables SCSI interface
solutions beyond Ultra320 to the next-generation Direct Attach Storage
enterprise server, storage systems, and high-performance workstation markets
while retaining device-level backward compatibility. The SAS standard defines a
device-level enterprise storage interface incorporating SCSI command sets,
serial point-to-point interconnections, dual porting, increased addressability
and the ability to scale to small form factors. Because the SAS physical layer
is compatible with Serial ATA (SATA), users will have the choice of populating
their systems with SAS or SATA hard disk drives, or a combination of both.
