Hello all,
The Data Center Management solution team is currently investigating
whether to fund a new component: HP3000 network resiliency. This
investigation is trying to determine how much interest there is in this
topic and what the scope of the project should be. We are trying to get
more details about the networking products, configurations, and/or
operations which cause the most problems to our customers.
You can help us by answering the following questions - there is a place for
comments too. We will use the information you return to us to determine
which products we can investigate to maximize the reduction of system
failures, hangs or other problems you encounter due to networking operations.
The more detail you provide for this survey the better we will be able to
determine the best course of action to improve the system availability.
Private responses are probably best, since the survey is lengthy in size,
but if there is any online discussion, please be sure to cc me.
If your interested in this topic, please respond by January 30, 1997.

Thanks for your participation.
Sincerely,
Lynrene Frueh and John Spitzer

Network Resiliency Questionnaire: Failures & Hangs
====================================================
1. Determine the products with the most problems
The following table contains a list of the products that comprise
the MPE/iX networking subsystem. In the table, indicate the
following in each column:
Frequency of use: Choose the phrase that best describes your level
of usage of each product on the following scale;
(1) Heavy usage - many uses per day or many large data
transfers;
(2) Moderate usage - several uses per week or moderate
size data transfers;
(3) Light usage - once a week or less or small data transfers;
(4) Occational usage - once a month or less or a few small
data transfers;
(5) Never;
(?) Unknown;
Frequency of problems: Indicate how often you encounter a problem
in each product:
(1) More than once per week;
(2) More than once per month;
(3) A few times per year;
(4) Less than once per year;
(5) Never;
(?) Unknown;
Severity of effect: When a problem does occur, indicate the severity
of the impact. For example, a problem might
occur very rarely, but the impact could be high:
(1) Very severe;
(2) Severe;
(3) Moderate;
(4) Inconvenient;
(?) Unknown;

2. Select the top 5 products which have contributed the most to your
system downtime. (1 indicates the product which causes the most
downtime). For each of these top 5 products, what types of
problems are causing you to rank this as a problem product? For
example, types of problem could include: system abort, system
hang, port hang, process hang, data corruption, failed to connect,
aborted connection, non-abortable connections or sessions.
Rank Product Name Types of problems encountered
1
2
3
4
5
3. Do you have specific operations or configurations that seem to cause
more problems in networking products? If so, please describe:
4. Are there any networking product problems that seem to re-occur
after fixes have been made to solve problems?
5. Are there other causes of downtime which significantly impact your
system? (For example, having to reboot after making NMMGR
configuration changes). If so, which products seem to cause this
downtime? How would you compare the impact of this downtime to the
downtime caused by the product problems discussed in question #2
above?
6. If you have any questions or additional comments, please feel free
to add them here:
