Capacity planning: case studies?

          Hello,
          does anyone know where i can find some case studies pertaining to clustering large-scale
          WLS/WLE applications. in particular, i am interested in the optimum number of
          servers
          in a cluster, nodes in a server instance, how to partition those nodes (by function/type?).
          thanks in advance,
          bob

Hi Bob,
 Unfortunately it depends primarily on the application. There's no simple
 math formula that provides what you are looking for. Generally, you can come
 to some conclusions only be load testing with reasonably good usage
 scenarios that reflect actual users. Then you can compare horizontal vs.
 vertical scale. Sometimes it is better to have a 32-processor box running
 one instance of WebLogic than to have a dozen 4-processor boxes because of
 little things like "db-is-shared".

Capacity Planning for Workflow Manager

Some information is available regarding highly available Workflow Manager implementations but I cannot find any information regarding when or how you should perform capacity planning for the workflow manager.
A few questions are jumping out at me.
When would we want/need a dedicated Workflow Manager server? (I can understand if this was shared between multiple farms this may be a benefit but what about from a pure capacity perspective).
Are there any case studies or documentation that we can use as a baseline estimation for capacity for the workflow manager?
Generally speaking for a small/medium farm deployment is it expected that this service also run on the application server?

That would really depend on what kind of workflows are being run and the traffic being generated by the users. If you have long and complex workflows, you will need multiple nodes in the farm to handle.
Our tests with very simple workflows on a 16-core 16GB machine with SQL Server on a diff machine showed that it could handle 400 incoming messages per second and 65 workflow executed per second. Now if you have complex workflows, it may slow down further.
If you have one msg per user per second - it may mean 400 users handled per second. But I wouldn't make that conclusion - u must test your farms against your scale needs and accordingly plan your farm capacity
Hope this helps

VoIP and Video capacity planning

For 1000 users, what is the bandwidth for backbone to run VoIP and video?
Thanks

the above link is very good as it pertains to 'per call bandwidth consumption'
you may need to use a little more to find your answer such as a capacity planning procedure(s). since you have voice and video, this will be two part.
(minding that video if used for all users will require much more capacity than the voice; possibly upto 50 - 100 times more depending on your use/needs)
some decent capacity planning providers, case studies and best practices are as follows:

Operations are not getting despatched in capacity planning table

Hi Experts,
I am using capacity planning table (Graphical) to level the capacities and sequence the process orders. The start date of my orders are very well in future and sufficient capacities also is available in resources. But when I go to CM25 and select one order and click on despatch, system is not despatching it. This is the case for almost all the overall profiles.
The surprising factor is, this function was working fine earlier without any issues. I havent done any changes in configs which will affect capacity planning.
What can be the reason for this? Any thoughts please?.
One more thing. Is there any option to avoid the capacity planning step if Iam using R/3 and manage it by some other way?
Appreciate your earlier reply
Thanks & Regards

Bandwidth Utilization Avg or Max for capacity Planning best practice

Hello All - This is a conceptual or Non-Cisco product question. Hope you can help me to get this best industry practice
I am doing a Capacity planning for the WAN Link Bandwidth. To study the last month bandwidth utilization in the MRTG graph, i am seeing two values
Average
Maximum.
To measure how much bandwidth my remote location is using which value i have to use. Average or Max?
Average is always low eg. 20% to 30%
Maximum is continuous 100% for 3 hour in 3 different intervals in a day and become 60% in rest of the day
What is the best practice followed in the networking industry to derive the upgrade size of the bandwidth by using the Utilization graph
regards,
SAIRAM

Hello.
It makes no sense to use average during whole day (or a month), as you do the capacity management to avoid business impact due to link utilization; and average does not help you to catch is the end-users experience any performance issues.
Typically your capacity management algorithm/thresholds are dependent on traffic patterns. As theses are really different cases if you run SAP+VoIP vs. youtube+Outlook. If you have any business critical traffic, you need to deploy QoS (unless you are allowed to increase link bandwidth infinitely).
So, I would recommend to use 95-percentile of maximum values on 5-15 minutes interval (your algorithm/thresholds will be really sensitive to pooling interval, so choose it carefully). After to collect baseline (for a month or so) - go and ask users about their experience and try to correlate poor experience with traffic bursts. This would help you to define thresholds for link upgrade triggers.
PS: proactive capacity management includes link planning for new sites and their impact on existing links (in HQ and other spoke).
PS2: also I would recommend to separately track utilization during business hours (business traffic) and non-business (service or backup traffic).

Setting needed for Capacity Planning.

Hi PP Gurus,
I want to know what setting we have to do for capacity planning.
what I know is:
1. W/C should be set for finite scheduling.
2. In scheduling parameters for process order tick "Generate capacity Requirement".
This both setting are made in my scenario, but it is'nt loading the work center fot that week.
Any other setting nedded?
Thanks, in advance.

Dear ,
You need to have following set up at basic level frist before you perfomr the capacity requirement planning :
1.In OPKP-Define Production Scheduling parameter -Availability check -Confirm Capacity and also Finite Scheduling chekc box ticked .
2.In OPU3/OPU5-Define Scheduling Parametesr -you should mark the following
1.Automatic Scheduling check box should be marked
2.Scheduling Log check box should be marked -generate in case there is a scheduling error due to capacity over load .
3.Scedulinga and Generate Capcity should be ticked .
3.In OPJK Imaintain check capacity with SAPSFCG013 overall profile and set indicator -1 -Release Order -by user decision if capacity is insufficient
4.Work Center - Define the capcity planner group,activate checkbox Relevant for Finite sceduling,on the capacity header define the shift timings,break timings and unit of measure,no of individual capaity, enter formula for scheduling in capacity view.
5.Routing - enter the values for the standard values. Use control key with scheduling and CRP activated .
6. OPD0 and have the following set up : Overall profile : SFAPSFC015 --Inside the over all profile I have the following set up
1.Selection Profile -SAPSFCS013 SFC: Order view, standard overview
2.Control Profile : SAP___C004 : Gen Capacity Availability Check for 1.5 months
3.Time Profile : SAP___Z006 : Gen Capacity Availability Check for 1.5 months
4.Evalution Profile : SAPSFCA013 : Gen Capacity Availability Chek =3.0D
5.Strategy Profile : SAPSFCVER1-Gen Capacity availability Check
6.Period Profile : SAP___P001 -Weekly period
7.List Profile : SAPSFCI001-Production Planing
Check all of them in place .Then you can go ahead with Capacity Req.Planning -Evalution and Leveling -CM21/CM22/CM05/CM07 etc.
Refere the below theread for farther reference :

Capacity Planning & capacity leveling

Dear All,
If we have two Sales Orders in the same date for two different materials which will use the same work center for processing, and if we run the MRP then two planned orders will be generated. Here according to the capacity planning the system will calculate the number of days required to process in the work center and the job will be assigned to the work center for planned order 1. Then when the system tries to allocate jobs from the planned order 2 to the same work order then the system will show the over load. Then we have to do capacity leveling to remove the over load.
But the clientu2019s requirement is that when the system calculates the available capacity of a work center in the planning horizon, the system should not consider the time for which the job is already assigned from the planned order 1. And the system should assign the job from the planned order 2 to the work centeru2019s available (capacity) time excluding the (capacity) time for which the job is already assigned from the planned order 1 in that planning horizon. If there is no Available capacity in that planning horizon then the system shall show the over load and then the client shall go for the capacity leveling.
How to go about Please help.

Hello Satish,
Let me understand you issue:
You would like system to give overload only when there is no capacity available in planning horizon.
Did you try using tabular planning board ? Tabular planning board uses bucket principle. It will give overload only when the whole bucket is full. It will not check the date and time of planned order # 1. While allocating capacity to plannined order # 2, the bucket's full capacity will be checked. In your case try allocation bucket size equal to your planning horizon period.

Capacity Planning for Azure Managed Cache Service Spreadsheet Missing

I'm currently choosing between dedicated in-role caching and the azure managed cache service. It seems pretty clear that for in-role caching one must consider the cache access frequency when choosing the in-role cache size (as demonstrated by the capacity
planning spreadsheet found here http://msdn.microsoft.com/en-us/library/hh914129.aspx although the documentation states "Your application
is the only consumer of the cache. There are no predefined quotas or throttling. Physical capacity (memory and other physical resources) is the only limiting factor.")
It is less clear if this is also the case for the azure managed cache service since the documentation simply states:
“Now, there are no predefined quotas on bandwidth and connections. Physical capacity is the only limiting
factor and you only pay based upon the cache size. You can now focus solely on your application and its data needs.”
and the capacity planning guide spreadsheet found here:
http://msdn.microsoft.com/en-us/library/dn386139.aspx
does not lead the actual spreadsheet.
Is there some way to get the capacity planning guide spreadsheet for the azure managed cache service? If not, can someone tell me whether we need to consider cache access frequency (and not just size) when choosing the azure managed cache service?
Thanks!

Just kidding, I found the planning spreadsheets here:
http://www.microsoft.com/en-us/download/details.aspx?id=30000
That said, I'm still unsure of whether the data read/write frequency (bandwidth) is relevant in choosing capacity:
In role:
"Your
application is the only consumer of the cache. There are no predefined quotas or throttling. Physical capacity (memory and other physical resources) is the only limiting factor."
Managed:
“Now,
there are no predefined quotas on bandwidth and connections. Physical capacity is the only limiting factor and you only pay based upon the cache size. You can now focus solely on your application and its data needs.”
I'm confused because when using the caching capacity planner spreadsheet,
when the number reads/second is increased, a greater cache size is recommended. But why would I need a larger cache size if the same object is being read by multiple users and there is not limit on bandwidth?

Capacity planning and levelling

Hi,
My client has around 8 different production areas and I have created 8 different order types,production schedulers,capacity planner groups and production scheduling profiles for the same. I have also created a list profile,selection profile, graphical profile, optional profile and an overall profile with my understanding.
1. I want to see for a given production area, In the morning, the user has to take the list of work centres pertaining to his area and fix priorities. In case he wants to move certain orders to next day and want to insert new orders in place of that, how to do this?
2. How can I utilise the feature of capacity planning, to evaluate my capacity requirements for new projects?
3. I want the step by step instructions for doing the capacity levelling both in graphical/tabular forms. Also please explain the purpose of different profiles used for capacity planning like selection,option,list etc.
Regards,
Sridharan M

Dear
Capacity planning comprises the following partial components:
Capacity Evaluation
In the capacity evaluation, available capacity and capacity requirements are determined and compared with each other in lists or graphics.
You can use capacity evaluations to analyze capacity loads in your company.
Capacity leveling
The objectives of capacity leveling are:
1.     Optimal capacity commitment
2.     Selection of appropriate resources
3.     In most applications, you can use two types of planning table (graphical and tabular versions) to display the capacity situation and to carry out capacity leveling.
4.     In some applications such as Repetitive Manufacturing (PP-REM) or Sales and Operations Planning (PP-SOP), there are application-specific planning tables for capacity leveling.
The objectives of capacity leveling include:
u2022     Leveling overloads and under loads at work centers
u2022     Achieving optimum commitment of machines and production lines
u2022     Selection of appropriate resources
Dispatching Operations
Dispatching operations is the main function of capacity leveling. Operations are dispatched to the time when there is sufficient capacity for them to be executed. You can also dispatch sub-operations and work elements.

Capacity Planning Metrics

Hi,
We are in the need to do a Capacity Planning for our database. We are planning to increase number of users from 250 to 750. Please help us what are the metrics we need look into it.
Database Size 4 TB.
Thanks,
Balaji. S

It depends.
Assuming that the number of users is a good proxy for the amount of workload on the database (that may not be the case particularly in a data warehouse environment where certain users are likely to be associated with vastly more expensive queries than other users), what is your database bottleneck? For most data warehouses (I'm guessing based on the 4 TB size), your bottleneck is I/O. So tripling the amount of workload is likely to require additional I/O bandwidth and/or more spindles and/or more RAM to cache more blocks. The next most prominent bottleneck tends to be CPU. So looking at your current CPU utilization and figuring out how many CPUs you need to add if your workload triples would seem reasonable.

Hi ,
The implementation of your SAP System covers the following phases:
Project Preparation
In this phase you plan your project and lay the foundations for successful implementation. It is at this stage that you make the strategic decisions crucial to your project:
Define your project goals and objectives
Clarify the scope of your implementation
Define your project schedule, budget plan, and implementation sequence
Establish the project organization and relevant committees and assign resources
Business Blueprint
In this phase you create a blueprint using the Question & Answer database (Q&Adb), which documents your enterprises requirements and establishes how your business processes and organizational structure are to be represented in the SAP System. You also refine the original project goals and objectives and revise the overall project schedule in this phase.
Realization
In this phase, you configure the requirements contained in the Business Blueprint. Baseline configuration (major scope) is followed by final configuration (remaining scope), which can consist of up to four cycles. Other key focal areas of this phase are conducting integration tests and drawing up end user documentation.
Final Preparation
In this phase you complete your preparations, including testing, end user training, system management, and cutover activities. You also need to resolve all open issues in this phase. At this stage you need to ensure that all the prerequisites for your system to go live have been fulfilled.
Go Live & Support
In this phase you move from a pre-production environment to the live system. The most important elements include setting up production support, monitoring system transactions, and optimizing overall system performance.
Rest you have some documents on help.sap
Regards
Rahul Bindroo
After your system has gone live, you can use a separate Roadmap with six work packages, in order to optimize your SAP System continuously.
These phases are the main milestones for your SAP System implementation project. Each phase has:
Work packages, which consist of activities, for which project teams are responsible.
Activities, which consist of tasks, which are processed by one or more team members.
Tasks, which are carried out by a project team member. You can also access the How-to sections and accelerators at this level.

Bandwith Capacity Planning for 100 user SSL VPN Facility

What are things we should conisde while doing the bandwidth capacity planning for SSL VPN Facility for 100 users ?

Hi Surya,
This is not an easy question, since there are so many things to consider that I may miss some of them.
1- In case you are planning to use an ASA, check this to find the ideal throughput for you:
         Compare Models
2- What type of traffic? TCP or UDP?
     If TCP
          Make sure you avoid fragmentation, adjust the MSS value if necessary.
     If UDP
          If fragmentation must happen, then set the DF bit to clear to allow it.
3- Make sure the clients always negotiate DTLS (which is by default).
As mentioned in the document above:
"Maximum throughput measured under ideal test conditions.
VPN throughput and sessions count depend on the ASA device configuration and VPN traffic patterns. These elements should be taken into consideration as part of your capacity planning."
Thanks.
Portu.

OAG Capacity Planning

Hi,
Please help me to clarify on how to properly plan the capacity for an OAG deployment. I’m taking as base OAG documentation:
http://docs.oracle.com/cd/E55956_01/doc.11123/administrator_guide/content/admin_planning.html#p_admin_planning_ha
formula described there helps to get the number of Gateways
numberOfGateways = (ceiling (requiredThroughput x factorOfSafety / testedPerformance) x HA) x (1 + numDR) + staging + eng))
I’m assuming each gateway is deployed in machines with following prerequisites, as described in documentation
Intel Core or AMD Opteron at 2Ghz with Dual Core or faster—i386 or x86_64 (32-bit or 64-bit)
Minimum 2 GB free disk space, 50 GB recommended
Minimum 4 GB physical memory
In the case requiredThroughput has significant increments, I think we should deploy additional Gateways, please help us to clarify
Questions are:
In order to properly scale OAG deployment, its just required to deploy new Gateways (in additional machines with above characteristics)?
Increasing physical memory or adding more CPU threads has any positive impact in performance?
Please advise.
Regards
Juan

Hope you are asking regarding the Manufacturing Capacity Planning.
Oracle Capacity functionality is part of the Manufacturing module license.
Oracle Capacity lets you calculate your Capacity load ratio by resource or production line.
It ensures that you have sufficient capacity to meet your production requirements.
Oracle capacity provides you with two levels of capacity planning :
Rough Cut Capacity Planning (RCCP) to validate your master wschedules
Deetailed Capacity Requirements Planning to validate your MRP plans.
