Maximum FCP connections

Dear All,
just a quick question. what is the maximum number of FCP suites (machines) that can connect to an XSAN network without losing throughput speed?
Ben

As William said.
You will need to account for the Metadata. Your plan should be to dedicate one of your controllers to your Metadata LUN and what ever you want to use the remaining space for (Render files, Audio, ETC.), so figure 7 drives are gone from your overall capacity. The remaining 3 Controllers and 21 Drives should be used to build your final Xsan Volume.
The overall throughput you will have available for your Xsan Drive will be between 240 to 300 MBs. DVCPRO50 is about 7MB/S per stream, so your 14 machines x 7MB/S = around 100MB/S. Your current setup will safely handle all 14 of your Edit Bays playing 2 Streams of video at the same time.
If your Realtime Video Stream requirements are higher than that, you might want to consider adding another Raid. Which will give you close to 200MB/S more throughput.
Basically, it comes down to a calculation like that. You should plugin your numbers if these aren't accurate.
Good Luck

Maximum RFC connections in RFC

Hi all,
i am facing a problem while trying to send lots of messages from R3 to XI via RFC Sender Adapter:
See the SM21 log in sender system: (R3):

it was a matter of the gateway, we needed to set the gw reg program parameter to a higher value!

Maximum JMS Connections

          Hi,
          I would like to know what is the maximum JMS connections weblogic server can
          handle anytime. And where do we set this parameter? we have a group of Message
          Listeners listening to a Queue on weblogic by opening JMS connections at the same
          time. So I was wondering how many JMS clients can Weblogic handle?? And also does
          it impact the performance of weblgic server.
          Thanx,
          Sankas


          Thanks for the information guys. It was very helful.

Best SQL Challenege: TSQL Query Maximum Concurrent Connections (Participants)

Hi All,
I have a table called dbo.PhoneCalls with below columns
PhoneID |PhoneNumber| Callstarttime| CallEndtime|
1 |111-111-1111|2013-04-01 05:13:03.000|2013-04-01 05:13:03.000
1 |222-222-2222|2013-04-01 05:15:12.000|2013-04-01 05:16:52.000
2 |333-333-3333|2013-04-01 05:17:29.000|2013-04-01 05:24:08.000
2 |444-444-4444|2013-04-01 05:21:50.000|2013-04-01 05:22:31.000
2 |555-555-5555|2013-04-01 05:22:41.000|2013-04-01 05:23:11.000
2 |666-666-6666|2013-04-01 05:23:20.000|2013-04-01 05:23:46.000
1. PhoneID is nothing but the participant in the call. PhoneID = 1 is twice from above. Which means 2 particpants (Same call
)with 2 numbers with their callstarttime and callendtime. Similarly for PhoneID =2, there are 4 participants. And the list goes on for a day and then for a month.
2. For example a phone call P1 with 2 participants is going on for a particular day. We should not consider the same phone
call having 2 participants involved. So that the concurrency would be 2. We have to ignore that here.
3. Only to be considered is other Phone calls for that day. Lets say P1 having call with 2 participants, P2 having some 4 participants
which fall in the time period of P1. Then we should consider P1 and P2 the common period
4. In order to find number of concurrent calls happened for a day basing on callstarttime and callendtime. What would be the
query?
5. Should consider the Timeperiod or the bucket with 1 hour as the period.
6. A Phone Call P1, Phone Call P2, should have matching (common) time ( keeping all the scenarios) is required for this query.
Result for Concurrent calls for a day should be like below. Should get all the concurrent connections happened for a particular
day.
Date|TimePeriod/Bucket(hr part)|Concurrentconnections|
Jan-01-2015|01 to 02|3
Jan-01-2015|11 to 12|2
Jan-02-2015|04 to 05|5
Jan-02-2015|12 to 13|13
ii) So once the above is achieved.
Have to find the Maximum concurrent connections for day from the above.
For below Maximum Concurrent connections are '3'
Date|TimePeriod/Bucket(hr part)|Concurrentconnections|
Jan-01-2015|01 to 02|3
Jan-01-2015|11 to 12|2
Hence the Result for Maximum Concurrent Connections would be
Date|TimePeriod/Bucket(hr part)|MaxConcurrentconnections|
Jan-01-2015|01 to 02|3
Jan-02-2015|12 to 13|13

Thanks George.
That was fantastic.
But
But I don't want the participants to be concurrent in the same call. And should consider the different call.
Lets say Phone Call P1 having 2 participants , obviously they are concurrent according to that call.
Only the Phone calls with more than one participant should match with other phone call with more than one participant.
A Phone call with any number of participants not matching with the time slot of other phone call should be ignored.
There might be a different call say P2, having some 3 participants at the same time or atleast fall in P1's time slot.
So
P1 --> 2 participants ---> start hour 10:00am ; End Hour 12:00pm
P2 --> 3 participants ---> start hour 10:30am ; End hour 12:30 pm
P3 --> 4 participants ----> start hour 11:00am ; End hour 11:10am
So the concurrency should ignore for P1 and should consider for P2 and P3. From above P2 having 3 participants, P3 having 4 participants. So the common time for all P1,P2,P3 is 11:00am - 11:10am.
Concurrency should be
Starthour EndHour ConConnections
10:00am 11:00am (2+3+4) ---> 2 for P1, 3 for P2, 4 for P3, because at exactly 11:00am there are 4 participants. So the time bucket or the slab for 1 hour will give us that concurrency at that particular slab. Except that independent
participants to that call.
So Result should be
Start Hour End Hour Concurrent Connections
10:00am 11:00am 9
11:00am 12:00pm 9
12:00pm 01:00pm 5

What to set maximum simultaneous connection to?

Hello
What do I set maximum simultaneous connection to (web server settings)? In Apache manual you can calculate "maxClient" by taking the avaiable free RAM and split that with the memory each httpd process using. In my case that would be: 6000 / 15 = 400 maxClient.
But in Apples "Web tech admin" pdf they write: "...Browsers often request several parts of a webpage at the same time, and each request creates a connection". Does that really mean that every image need a separate connection – or have I missunderstand anything?
At the moment I have it set to the default 1024. But, CPU usage is very often in the 90-100% region… So, should I go by Apache's definition or Apples default?
Best regards, Magnus

You'll want to look at where the CPU time is going across everything that is going on, and at how much memory is in use; at a more holistic approach toward tuning. Unless you're getting a substantial load on Apache or unless you're very marginal on available memory, tweaking the maximum processes isn't usually a huge win.
If you are looking at comparatively large volumes of http traffic and that 90-100% CPU is largely web-related, then you'll want to profile the server using the Safari or other tools, and look at optimizations and at web caching, and potentially at adding web servers.
And yes, a web browser can have multiple parallel connections into a web server.
The maximum connections stuff sets up the numbers of Apache http client processes, which is why you're looking at memory with that discussion you've found.
Something similar to this command will get you the accumulated CPU time and the memory (rss) size for the Apache processes:
ps -A -o ucomm,rss,time | grep -i httpd
There are Apache tuning articles around the 'net, but I'd first make sure it's Apache that's soaking up the CPU time and not some other constraint.

Maximum allowed connections

Hi everyone.
We have a small office here, and we have about 11 people at max, who would like to connect to our server, a mac mini. Most of the days, part of the staff is not in the office, so this is not usually a concern, but on a few select days, the entire staff is in the office, and that means an unlucky soul can not connect to the server.
Does anyone know if there is a way to increase the maximum allowed connections? We are running Mac OS X Server in our main office, but I was holding off from doing do in this office.
Any advice is greatly appreciated.
Thanks in advance!

SharePoints changes the number of items that can be shared but AFAIK it does not change the maximum number of connected users.
Can you tell me how to make SharePoints change the maximum number of allowed connected users? I couldn't see anything in the documentation that indicated that the number of users could be changed.

Maximum Simultaneous Connections lower than 5?

XIR2 on Windows: on the webi report server, the lowest value I can use for the setting "Maximum Simultaneous Connections" is 5.
Is there any way I can change this manually, possibly in the registry so this value can be set as "1"?
Thanks in advance
R

The important thing to realize about wireless is that it's a shared medium and only one device can transmit at any one time on a given channel so the number of users per AP will depend largely on what sort of traffic you'll be putting over the wireless.
If you expecting it to replace structured cabling in an office environment then you can probably expect quite a bit of data, especially if you have a Windows domain and fat clients.
I wouldn't put more than 7 - 15 users per radio (depending on load)
If you install a dual radio AP - something like an 1142a/g/n, then you can split the users between the two frequencies (assuming that some of the clients support 802.11a) and if they support N then that's even better
For that number of users I would strongly suggest you install 3x APs (dual radio), that way you can have 3 non over-lapping channels in the 802.11g frequency and will be able to provide the best possible performance to the users
As a side note you should also connect the APs to Gigabit ports so that you get the benefit of the higher throughputs provided by 802.11n

Maximum Simultaneous Connections??

In the server admin for Leopard it has a default 1024 for maximum simultaneous connections. The most you can enter in the server admin is 2048.
Is there a way to edit some files to allow for 10,000 simultaneous connections?

Specifically which service are you talking about?
I'm guessing you're talking about web services, but it's important to say so because each service has its own set of limits.
That said, 1024 is a LOT of connections for any web server. Don't forget that only applies to actual active connections - people downloading a page from your server. Once the page is served the connection is available for some other user. It may take the original user a few seconds to read the page before they click a link and go to the next page.
For reference, I run many sites with millions of page views per month and most of my servers sit in single, or maybe double-digit numbers of active connections at a time.
If you think your site is really going to have thousands of simultaneous active users you probably need to look at what you're doing and scale across multiple servers rather than trying to run that much traffic through a single machine.

Are you facing the same problem? If you have any suggestions, please tell me, thanks.

This is an old issue. Read Doc ID 749386.1 on MOS. The suggested fixes are as follows:
1. The maximum number of connections that are allowed per Port is 250. There is a 250 connection limit per port. Please use a different user ID and desktop as the workaround, so this way a different port can be used.
2. If using a different user ID and desktop is not feasible, increase the value of the maxlogins parameter as indicated below:
Increase the maxlogins in the Essbase.cfg file to 5000, and restart Essbase.
Note: Make sure that there are no sessions active within the EAS console before restarting the Essbase services.

Maximum simultaneous connections for WRT350N

Hi,
What is the maximum number of simultaneous connections that the WRT350N router can handle whilst allowing 1 user to surf the internet?
I need to know this so I can set the maximum number of connections in uTorrent. My upload speed is 1.1 mbps, which is roughly 140 kBps.
The PC has a direct connection to the router, the wireless has been turned off.

There is no such defined number of user for TCP/IP connection.However,you can try to tweak the settings on the application and check if that helps.read this link and this link.

HT5390 mac os x is there a maximum on connected servers in the sidebar of the Finder window?

Hello,
I have a server with four partitions connected to my mac. At startup they
automatically connect, and show up in the sidebar. Or... that's how it was for years.
The new Mountain Lion sidebar shows only two of them, and it is impossible to
put the others in the sidebar. It refuses to add them.
Is there a limit of servers(partitions) that may be added to the left sidebar of the finder?
ps. Maybe i am the only one that has this issue.
I look for a .plist preference file to delete, but i don't know which one.
Thanks
Hans

Hello Hans,
Normally in Client OSX the limit is 10.
Mount that Share once, then once the Globe Icon shows up on the Desktop, drag that Globe Icon to the right side of the Dock between Applications & Trash. You now have a Dynamic Mount, a quick click on the Icon in the Dock will connect you.
On the multiple Shortcuts...
Mount them all, when show up on the Desktop, then create a new Folder maybe named Shares on/in the Desktop, drag all those Shares shown on the Desktop to that Folder, (you can even rename them once there, if you wish), drag that Folder to the right side of the Dock between Applications & Trash, this should give you a popup menu to select from.:-)
To automount them, drag those Aliases to the Accounts Pref Pane's Login Items Window.

No, Im not saying ACS cannot cope.
Concurrency and latency are very different things. ACS CSTacacs can handle many 100s of simple authentications/authorisations per second with users in the internal database. If 1000s of devices all send traffic in the same instant it would take some seconds to work through the backlog of traffic.
Also, worth considering that a limited number of tasks within ACS (or threads) can actually handle a much greater number of "logins" because they are generally multi-message allowing ACS to keep lots of plates spinning.
If users are in an external databases the latency (per authentication) can increase depending on where the users are (eg Windows AD) and if bad enough can have a serious effect on the overall authentication rate. At which point customers normally turn to load balancing.
If your device timeouts are 20 seconds (totally reasonable) I suggest the issue is more likely to be something else... a bug, perhaps specific to v4.2?

Maximum user connections on an AP 350 and 12xx

Is there somewhere a table that discribes the number of connections that can be made on an AP like the 350 and the 1200 series, no voice, just data with eap-fast

From the wireless FAQ:
How many clients can associate to the AP?
A. The AP has the physical capacity to handle 2048 MAC addresses. However, because the AP is a shared medium and acts as a wireless hub, the performance of each user decreases as the number of users increases on an individual AP. Ideally, not more than 24 clients should associate with the AP because the throughput of the AP is reduced with each client that associates to the AP.

CSS11000 - Configuring Maximum TCP Connections

Hi,
Maybe this is a stupid question. But I'm going to ask it anyway :)
If I set the max connection on a service can I redirect the connections that are over the max connection to an error page?
Or I'm I looking in the wrong place. I'll try to explain what Im trying to do.
I want to protect my application servers, if my application servers reaches a certain threshold I want to redirect the connection to a error page.
How should I tackle this problem.
Thanks in advance for your help.
Geert

Hi Gilles,
First of all I wanted to thank you for help. Very kind of you to take time helping us.
Second of all I want to apologies for my first post. I should have been clearer about the problem.
Let me try again.
Our web servers connect to our backend vip. Now the specific application doesnt like being switched from one server to the other while in the same session. We tried to solve this problem but we didnt succeed.
Now we gave up balancing that application.
But now we want to set a limit on how much connections can flow to that one application server. So the application server wont give up under high load.
Now when the load goes above a certain value we want to display an error page. Something like sorry try again later. But if server 1 crashes we want all connection goes to server 2. We dont want the connections to go to server 2 when the max of connections is reached. Because than we want to see the error page.
When I tried to create a redirect service to an url I got :
%% Cannot have a redirect service on a Layer 4 rule.
Now the redirect to an error page isnt a real must. More a nice to have. But what we would like is that the server2 only takes over if server1 is down and not when the max connections is reached.
Now this is what I have by now. But now Im a little bit stuck. We noticed than if we are load testing the webserver thinks app1 is down because it reaches the max connections and goed to server two. Witch we dont want.
