How many Meraki APs per subnet/vlan

I am trying to cover a 90-story building. Voice is not a requirement, but I would like to be able to seamlessly roam across the infrastructure. How large can I build a flat network, and if I need to cross a threshold, what do I have to do to enable Layer 3 roaming?

The only reason I can thing of why that "soft limit" of 60 Cisco AP's per VLAN exists is the default logging configuration of the AP's. This is the broadcast address so every other AP receives all those messages also, once you configure an syslog destination that is no longer the case. I don't have much experience with Meraki, but I think that they don't work with an external syslog server at all.
I hope that all the other devices are being segment it on a per floor basis? If not, please investigate if you can segment at least some floors together with there own set of "local" VLAN's. You don't want network traffic being switched in "global" VLAN's all throughout the building on a scale like that.

How many DAQ tasks per loop?

Hi to everybody, I hope anybody can help me with the next case:
I am working on a system in which I have to read signals of 5 different sensors which have different ways to communicate (4 - 20 mA, voltage, RS-232, ModBUS, etc.) with the DAQ Device (cDAQ in my case), at same time when I am reading the variables I must check for the state of several digital inputs to verify connections and if any is interrupt I must stop the Data Acquisition.
My question is if is recommendable to put all the tasks in a single loop with the logic shown in the attached image.
Or if I should divide the tasks in a multiple loop architecture.
If the answer is the second, my next question is: How many DAQ tasks per loop is OK?, my doubt is based on the number of variables that I am going to read
and the different ways to get the measures, specially which are by protocols (ModBUS, RS-232), all this by the response time.
Thanks in advance, all suggestions are welcome!

I would recommend using a loop just for control and UI events. It should only have an event structure. Don't use the timeout case, since that just turns the system into a polling. Use Queues to send data from the controller loop to your other loops and User Events to send data back to the controller looop.
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

Need FM/BAPI to get how many line items per given FI document...

Hello Experts,
IS there an available FM or BAPI to get how many line items there is for a given
FI document? We are avoinding BSEG because of the performance.
Hope you can help me guys. Thank you and take care!

Hi,
Not sure if there is a specific FMs or BAPIs whose specific purpose is to just count FI document lines. But you can use a number of FMs to read an FI document.
i.e. FI_DOCUMENT_READ - pass the document keys (BUKRS, BELNR, GJAHR) and retrieve the T_BSEG table to get the document lines. Then you can just use DESCRIBE statement to get the number of lines in T_BSEG.
Also, based on experience, I never had any problems with BSEG as long as I am providing the complete keys for an FI document (BUKRS, BELNR, GJAHR). But if you are trying to avoid BSEG, you can use the secondary index tables like BSIS , BSAS, BSAD, BSID, BSIK, BSAK to improve performance.

How many iPhones stolen per day? Prevent shutdown.

Dear friends.
Since I had my iPhone stolen I'm searching for a way (without jailbreaking it) to prevent that my new iPhone gets lost.
"Find my iPhone" is only useful when the thief is dum.b as hel.l and when nobody has found it (yet).
Does Apple see comercial advantages on this situation? How many iPhones are stolen a day?!
I mean, why in the world wouldn't you develop security apps and security features so we don't lose our beloved phones?
This is serious, and it seems Apple doesn't care. I don't want to jailbreak my iPhone, but you are not helping, Apple!
I would like to see a Restriction setting that would block the shutdown of my iPhone when it's locked. It would require a passcode to shut it down. It's so simple!
This way thieves wouldn't be able to shut it down!
The same works for Airplane mode and Wi-Fi. A passcode should be required to turn it off (if I enable this feature).
Advanced considerations: DFU mode and recovery mode should "expire", the iPhone should reset itself after some time (e.g. 10 minutes) so the iPhone would come back to life and allow tracking.
SECURITY!
So far nothing was done in this area. I believe Apple should pay more attention to this.
Best regards,
Will

Sorry requiring a passcode to shut down the phone isn't a good idea.
do you know how many users forget their 4 digit passcode to unlock their phones - use the search function at the top right and you'll see all the threads.

How Many MB/GB per Minute of Video?

I'm trying to decide which iPhone 5S to purchase 32gb or 64gb. Since there's been a few more improvements, since the 4S, I'll be depending on this more to shoot videos of my kids while vacationing, sports, etc. with maybe no place to upload.
Is there a standard, for this quality of video, of how many MB or GB it equals to in minutes and/or hours?

How many external drives per Firewire 800 bus?

I am the proud owner of a new Mac Pro, which comes with only one FW 800 bus. I have 4 1T G-Tech FW drives (2 for video media) that I've daisy-chained, and I know their performance is suffering because of it. I'd like to remedy that.
Question 1: Is it optimal to have only one of these drives running on each bus? Can I get away with two per bus without serious loss of efficiency? Can I assume that 2 per will run better than 4 per?
Question 2: For the price that OWC is selling the Sonnet Tango 800 PCI-E card (about $110), is there another card I should be considering, or is the Tango 800 considered good?
Thanks.

videocrafter,
not to presume on your time more than i already have -- what a helpful reply you gave. thanks! -- but i just want to make absolutely sure of one thing:
i buy the esata pci-e card you mention from OWC and install it myself (probably pretty easy) and then just plug my G-Tech drives into it, and I'm good to go? No separate esata controller card? I just realized that only two of my four G-Tech drives have the esata connection, so I could plug those two in, leave the other two with my FW 800 connection and save up for a couple more G-Tech drives with the esata connection. And this will make my life better.
Correct?
many, many thanks.
giraut
Hi giraut, your welcome
That is correct, you will not need any additional controller card. You will have to install the driver for the Tempo E4P (make sure you follow the installation instructions) and you'll want to make sure you download the latest driver from Sonnet's website:
http://www.sonnettech.com/support/kb/kb.php?cat=338#position_content
and unless you have some application monitoring for new upgrades, I would check at least once a month if not more often for any new future drivers. They are suppose to be coming out with one here soon to support 64 Bit. Even though FCP does not yet support 64 bit if you choose to run other applications in 64 bit you don't want your eSATA controller to cause any problems.
You'll also need One external shielded eSATA data cables with "I-Shape" connectors for each device you connect to the card. So in your case, you'll need 2 right away. Here is the type of cable you need, it just happens to be made by Sonnet, but you can find cheaper ones (just remember, you get what you pay for).
http://eshop.macsales.com/item/Sonnet%20Technology/TCBSATA11/
There is one bit of insight I would like to give you when swapping any of your internal drives around once you have this card installed. It probably tells you in the owners manual, and I just stopped reading once I got it up and running. However I found out the hard way. The first time that I swapped out one of the "Internal" drives (I swapped out the drive in bay 3 I think it was, makes no difference which bay I'm sure) but I simply shut down my system, unplugged the computer and swapped out the drive. When I started back up, I things didn't' seem right, it wasn't seeing my external drives properly and I got a panic attack (both the computer and me!). Of course my first thought was "YOU'VE GOT TO BE FREAKING KIDDING ME!" So after I took a deep breath, before turning the computer back on, I disconnected my external enclosure, then restarted and everything was find. I then completely shut down, turned on my enclosure and restarted. All was good. I tested my theory again and swapped out another internal drive and all went like clockwork. Here are the exact steps I took. They worked for me, and maybe they will work for someone else, so I'll list them here:
Swapping Internal Drive
1. Eject each external drive from the enclosure and power down the enclosure.
2. Eject and power down the FireWire drive.
3. Power down the computer and swap out drives.
4. With the external enclosures powered off, power up the computer as normal.
5. Accomplish another shut-down.
6. Make sure all of the drives are installed into the enclosure, turn on the power.
7. Power up the computer and keep your fingers crossed.
Personally I've never daisy-chained Firewire drives (although I find it fascinating that Patrick had 19 of them daisy-chained) if I did I would probably only use them for archiving since I capture and edit everything in ProRes 422, but that's another thread. I currently only have one device that I use via firewire 800 which is my external Blu-ray burner. An interesting note here. I initially had my Blu-ray burner connected to my former piece of junk eSata controller card (with the Silicon Image SiI3124 chip and drivers that haven't been updated since before Leopard came out) but for whatever reason, the Tempo E4P wasn't seeing it (Now I'm not sure why, and frankly I didn't take the time to troubleshoot it, so it may be nothing) I just went ahead and connected the burner up as Firewire 800, and connected my 3rd external eSata device (a OWC Mercury Elite Pro USB/Firewire/eSata drive) to port 2 of my Tempo E4P, with my 5 drive bay FirmTek/5PM eSata enclosure connected to port 1 of the E4P (leaving 2 open ports on the E4P).
So, If I were you, for now I would go ahead and daisy-chain those other 2 Firewire drives, unless I needed to use them to capture and edit in anything other than DV, or for archiving only. Otherwise, I would get another 5 bay enclosure and take those 2 SATA drives out of those 2 existing firewire enclosures (Im assuming they are SATA drives inside their enclosure, I would surely think so) and put them in the external eSata enclosure.
One last ti-bit of information that may or may not be useful. When you get an external 5 bay enclosure with the port Multiplier, pay a little extra for a brand that you can trust. Personally, since I already have one, I would stick with the SeriTek SATA5PM (their built like a tank!), or go with a Sonnet, OWC has a new price on their Fusion D500P that's pretty appealing. I would definitely be cautious if wanting to purchase anything for a specific company with the word "Cool" in their name, the only thing that is cool, and it's only cool for them is they get your money and you get .... well you know!

Re: How many amps/watts per header on Z77a-G45?

What about the pump in addition to those two fans though?
The H80i GT only has a 3-pin connector to power the entire unit (or I'd use molex/SATA for power)

How many max connections opened do you have?

Hello!
I've read so many answers to these questions that, i don't really know what is the correct one. So, i would like to know what do you have. Here they are:
1- How many max connections per torrent do you have set up?
2- How many max opened connections do you have in mldonkey (or similar)?
Thanks!
Last edited by dienadel (2007-03-08 08:25:36)

AFAIK it's arround (total connections):
- <5 for RTC
- <100 for slow ADSL
- <500 for medium ADSL
- ~1000 for high-speed ADSL (and max on Windows lol) ; went up to over 1500, without positive change.
I use rtorrent & have a limit of <100 connections per torrent (4 leechers max per torrent so they get something)

How many APs Can I join a WLC 4402 and WiSM?

I have a WLC with 20 APs joined into the same management VLAN and
I'll deploy other campus with 240 APs and 2 WiSMs Blade.
Is there any recomendation about how many APs Can I put on the same management VLAN?
thanks a lot

WoL across subnets, how many helpers can you use?

Been going through the searches on this and I can't find an answer to my question. We are implementing Dell KACE and are deploying WoL campus wide. I'm following the referenced doc and in our test environment its working well.
http://www.cisco.com/en/US/customer/products/hw/switches/ps5023/products_configuration_example09186a008084b55c.shtml#diag
My question is this part --------v
I get the need for the bolded helper addresses on the server VLAN. However, I have nearly 150 target networks to deal with. We are on a Class A 10.x.x.x.x, Is there a better way to break this down or do I have to put a target entry for each subnet like the example. I don't want to combine networks because I don't want to broadcast that traffic over that many networks and hosts. Any ideas.
L3(config-if)#
interface vlan 3
ip address 172.16.3.1 255.255.255.0
ip helper-address 172.16.2.255
ip helper-address 172.16.4.255

I do not believe that there is a limit on how many helper addresses can be configured on a router. I am not sure if the same is true on a layer 3 switch (and I assume that what you are showing us is a layer 3 switch). You might just configure it will all the helper addresses and see if it works.
It might be possible to implement some hierarchal approach. If your 150 networks were in 10 regions each of which had 15 networks, then it might be possible to put 10 helper addresses on the router/layer 3 switch where the WOL server is located with each helper address going to a region. On the subnet at each region there could be another router/layer 3 switch with 15 helper addresses to send the broadcast out to the networks in that region.

How many mails i can send at a time per day using APEX mail system?

HI,
I am working on application, when i have written a process to send mail, i have a project where i have to send mail at a time for all the email id's
given list there are upto 5000 email id's where text body also include certain set of data from a report. thinking at a time 3000 its difficult i divided
it region wise, but still each region have 2000 odd email id's. during testing when i run the process just 950 mails i could send then i got a error
saying "ORA-20001: You have exceeded the maximum number of email messages per workspace. Please contact your administrator." so please
can any one help me to know How many mails i can send at a time per day using APEX mail system?
Thanks in advance
Gowthami

Hi jfosteroracle,
You are getting the error may be the following reason,
Check the following,
Login as ADMIN and Goto -->Manage Instance-->Instance Settings--> Mail-->Maximum Emails per workspace
Actually this number denotes the Number of mails can be sent per 24 hour for the workspace,It may exceeded.
It may be the reason.
Thank you.

I'm a school tech coordinator. Many computers and many iPads. How many Apple IDs can I have per device, and how many devices can have the same Apple ID? To make my life easier, I'd like 200 devices to all use the same Apple ID.

I'm a school tech coordinator. I have many computers and many iPads. I apologize if there is a some place that has all the rules governing the use of Apple IDs. I looked, and I even tried to get the answers from multiple Apple rep's. I couldn't find the answers.
How many Apple IDs can I have per device?
I want to use the same computer to sync and backup many iOS devices. The iOS devices would be associated with different Apple IDs.
I may load apps under a school Apple ID and have users load their own apps under thier own ID.
How many devices can have the same Apple ID?
Can I use the same Apple ID on all the computers in a lab?
Can I use the same Apple ID on all iPads for a particular grade level?
Are the rules different for iOS devices and computers?
I know that there are limits on "authorize" and "de-authorize" and how frequently those things can be done.
Recently I heard that for the life of an iOS device, it can only be associated with five Apple IDs. That is not good for a school giving iPads to students in a 1:1
To make my life easier, I'd like 200 devices to all use the same Apple ID.
