When to use Windows NT on the IOPs

When to use Windows NT on the CEs

The HPAA system features three distinct installations of Windows
NT in operation; one each for the IOPs and one for both of the CEs.
Remember, the CEs operate in lockstep and use the same copy of
Windows NT. Regardless of which CE is being viewed based on the
tuple choice, any modifications made to Windows NT on the CE
occurs once, but it written to two different disks on each IOP for
redundancy.
When working with the Windows NT operating system on the IOP,
it has no bearing on the other IOP. All administrative tasks
performed on one IOP for the purposes of the HPAA system most
likely have to be performed again on the other IOP.
When the HPAA system is first delivered, there are only the default
user accounts and groups on the Windows NT operating system on
each IOP. The first administrative task would be to change the
administrator password as a security precaution on each IOP.
During normal operation of the HPAA system, the IOPs do not
require any access or adminsitrative use other than to use the
Marathon Manager. The Marathon Management Tool is installed on
each of the IOPs and it useful for:
•
Getting a status update on the array from the IOPs perspective
•
Checking the status of the array in the absence of a working CE
•
Performing / Issuing Marathon-based administrative commands
when the CE is not available
The IOPs do support the installation of additional applications, but
other than management tools this is not recommended as other
applications may impact the availability of the IOP and impact the
performance of the overall array.
The short answer is almost always. The copy of Windows NT is the
copy that supplies the resources for the client network. It is where
all applications are installed. When installing applications and
configuring the server to have the tools and accessories needed to
optimize performance conditions and services for the network,
always think in terms of the CE. Some of the typical administrative
tasks in a Windows NT environment to be done on the CE include:
•
