s simplify the provisioning
task
(deployment and assignment of resources
) that IT
A
dministrators face.
A
logical server
definition exists independent of
the underlying
serv
er resource
(server blade or virtual machine) it is assi
gned to at any given time
. Using
Insight Dynamics
--
VSE
,
an
administrator can use the same set of tools for provisioning a server, whether it is a
s
erver
blade or
a
virtual machine.
In both cases, the provision
ing step involves assigning a
logical server
t
o a
particular server resource.
Insight Dynamics
--
VSE
also simplifies the tas
k of moving a workload, for
example,
a
logical server
can be easily moved from one server resource to another.
A
logical server
also
describes
an abstracted
system image
1
.
The system image includes everything
that the OS and application stack require
s
to
support a
particular workload. For example
, a
logical
server
profile may
include attributes describing entitlements such as power allocation,
requirements for
processor
s and
memory,
and
identifiers (
IDs
)
associated with
netw
orking
and storage
addressing
.

System image is a term that represents the
serv
ices and
components that are exposed to the OS,
including the
storage
and
networking configuration
,
server identifiers, and the BIOS services and configuration.
