normally supported in these
cabinets may be racked with the
arrays as long as the total current
draw of the equipment does
not exceed the 16-amp rating.
A Hewlett-Packard representative

New HP disk
declassification capability
If you are in the aerospace, defense,
or electronics industry, you may be
concerned with information left on
magnetic
after it has been
erased, a problem
as
magnetic remanence.
This problem
occurs when you want to
move a disk from one location or
project
to another.
One method
to solve
this
problem
has been outlined by the U.S.
Defense Investigative
(DIS)
and is contained in a document
called Department of Defense
Magnetic Remanence Security
Guideline.
guideline specifies
that the disk
be overwritten
'n' times with a specified bit pattern.
Although
requirement
is not
new, an approval process
is
now
required stating that the erasure
procedures meet DIS requirements.
The DIS recently approved the
Hewlett-Packard procedure
for
HP disks.
