M.2 Compatibilityand Bandwidth Question

Hello all,
I am going to be building my first PC and am trying to get all of my information straight before i buy everything. I am looking to get:
Intel i7 5930K
MSI X99 Gaming 9 AC mobo
512 GB Samsung xp941 SSD
gigabyte gtx 980 g1 gaming (x2)
I have tried searching low and high through the internet, forums, and manual but cannot come up with a 100% sure answer.
So my question is if i have the xp941 in an adapter in a PCIe slot, being that it is PCIe gen 2 and x4, will that affect the bandwidth of my two graphics cards running at gen3 x16 each? I am not sure if putting a gen 2 in a gen3 slot downgrades all of the slots to the lowest generation or even lower lanes. And if i am using a M.2 PCIe adapter card (only using the adapter for the heat sink) will i still be able to boot from the SSD?
Also, looking at the compatibility list for this board, it shows the xp941 but only in the 256 GB size. Will the 512 GB version still be compatible?
Thank you all so much for your help in advance

First of all using a gen2 card does not affect cards in other slots. Gen3 cards in gen3 slots will stay at gen3. However there are population rules that will switch available lanes depending on the slots populated and the cpu used (5820K: 28 lanes / 5930K and above: 40 lanes). To keep both card in x16 mode and using the M.2 adapter card you need to follow the population rules for 3-way SLI. The vgas need to be used in PCI_E1 and PCI_E4 while the M.2 card needs to be used in PCI_E5. Of course it would make more sense to use the M.2 SSD in the onboard M.2 slot and don't use an adapter card at all. With your 40 lane cpu you could still use vgas in PCI_E1 and 4 while using the SSD in the M.2 slot with full bandwith.

Usually yes.

There should be no problem as the capacity should be pretty irrelevant if the SSD type is compatible. MSi can't test all drives and other stuff available so a component not mentioned in the list is not automatically considered incompatible but in most cases simply not tested. For a confirmation - if wanted - you need to contact MSI directly: >>How to contact MSI.<<

Bandwidth Question

I wanted to ask a question which has been playing on my mind for a while now. Thought this is the best place to ask.
I am currently on ADSL+2 and i get around 17mbps-19mbps live 650meters from the exchange line lenth 19db.
Now my exchange is going to be live for Infinity soon, im not planning on switching just yet as i pay a heavly discounted price on my broadband package and if i want to upgrade i will have to pay full price = £15 extra a month.
It got me wondering that if BT ADSL customers start switching to Infinity, will it mean less congestion on the ADSL network? like will it benefit me? or are both BT's FTTC and ADSL bandwith combined? Its hard to explain but im sure most of you understand what i mean
Solved!
Go to Solution.

@Eamdad
They use different backhaul through BT Wholesales network but the same links into BT retail, so in theory you are correct assuming BT retail have enough bandwidth on their interconnect links.. However i agree with john46.. the number of people switching probably won't make a lot of difference

General mail bandwidth question...

We are using a software spam solution on a separate server that filters the incoming mail by domain, then sends it on to OSX Server mail. We only have about 100 users.
We have what we consider to be a fairly good connection to the internet, 10MB x 2MB, yet it seems like the processing and handling of email is using a lot of our bandwidth.
We think it is because of the large amount of spam we are handling. We are averaging about 55,000 messages per day incoming, 75% of which is quarantined as spam, the rest being delivered to the users. That comes out to about 130+ emails per account per day that are potentially spam.
We will be ordering a new spam appliance shortly that will bring the catch percentage into the 99% range, but here is the question:
We obviously must accept the incoming mail to process it for spam, thereby utilizing bandwidth. Are there methods we can use to detect and stop the flood of spam, maybe at a TCP level before it takes up bandwidth?
The spam has just gotten ridiculous. It is up 8 times from a year ago. Looking for thoughts or directions to look into.

It only gets worse. Over 92% of the traffic to our machine (130 domains, 1000+ users) is spam. About 80% of that gets nailed at the RBLs, half of the rest by our filters, and the rest end up in user boxes to be postprocessed by SpamSieve (or whatever Qurb became for our Windows users). Apparently it is still against the law to exterminate spammers, and there seems to be a large percentage of the breeding population who still purchase their promotions, or can't secure their Windows botboxes, so through the magic of compassionate capitalism and certain lame OSen, spam is not going to die anytime soon.
You could offload your processing by using the likes of Postini or other services, or the spam appliance you mentioned. Beyond that, or my very tongue-in-cheek suggestion of vigilantism, there is no cure.

5508 - 3502 AP bandwidth Question

OK,
Here is the quick rundaown...
Our public wifi circut (verizon wireless) was upgraded from 25M to 150M due to over 500 devices connected and fighting for bandwidth.
I noticed when runnung tests that when associated to th 3502 AP's Im getting around 9.7Mb down. On ANY of the 3502's
When I move to a 3602 and associate to it, I get roughly 35Mb.
Im asking if anyone knows if there is a bandwidth limitation on 3502? Is there a setting on the WLC or the AP itself?
Thanks

ok, so you are using Bronze, do you have LAN side QoS in place?
What type of port are the AP connected to? 100M 1G etc
How many ports do you have connected from teh 5508 to the switch? LAG or individually connected?
HTH,
Steve

FTP Bandwidth question

I have a disagreement with a co-worker. I feel if I'm connected to an FTP site but not up or downloading I'm using minimal bandwidth. He is convinced that just being connected is using loads of bandwidth. That makes little sense to me but I'd like an expert opinion.
If I'm looking for a file on an ftp server that will be there some time in the next 2 hours I see no reason to not be connected and refresh periodically to look for a file rather than logout and login.
alan

Hi alan ruta-
I do know that it will tie up the connection until you either release it or the server kicks you off. If the server is only allowed to make, say, 10 connections and you and nine other people are logged in and doing nothing it would be a problem for that 11th person.
There is a small amount of handshake data sent periodically but I believe it is a negligible amount compared to an actual file transfer.

The bandwidth question

Hi folks,
i just have finished my website, but now I am concerned about
the size of the bandwidth. There are 3 pages. On each page there is
an embeded video (14 mb) which starts to play everytime viewer
visits that page. So that is total of about 40 mb of video files,
which will be playing basically all the time. Would anybody give me
an idea, what bandwidth package I may need for this? Thank you very
much for any input or advise.

Bandwidth Questions

I want to create a searchable site with lots of videos based
on either a
MySQL or SQL server DB (have not decided yet). I want to
figure out how
much bandwidth will be necessary based on the videos I want
to use.
1. When looking for hosting options, I have no idea what
50GB, or 100GB
of bandwidth is. Is there some formula or way for quantifying
this in a
way that I can understand.
2. How do you determine how a stable a site/host is going to
be? Does it
matter if the videos are viewed simultaneously or just when
they are
first requested, etc.
Thanks!

The bandwidth is how much data is allowed to flow to and from
your site.
If you have a 50Gb limit, thats 50,000Mb. If you have a 100Mb
file, it
can be viewed 500 times. Or, if you have 100 x 100Mb files,
they can
each be viewed 5 times. You have to think about all the size
of all your
pages, the images, any external javascripts, or CSS files. It
all adds up.
How popular do you want your site to be? Are you having just
one server?
On one network? What kind of backup will you have if the
server fails?
What if there is too much traffic for the server?
People like Youtube have massive networks with servers all
over the
world, all load balanced, so the website appears to be online
all the
time. Last I heard (a couple of years back) they had hundreds
of staff,
just for one video site. The money it takes to keep it
running must be
huge. W

Lots of testing by people who know what they are doing will
help the
designers make a stable site. You will need high quality
servers, with
spares, to keep your site stable. You will need almost
unlimited
bandwidth, and a network with resilience.
Why reinvent the wheel? Its been done lots by lots of people,
you may as
well use there services, and leave the headaches to them.

TCP Client Server - how to set timeout and bandwidth option

Hi Friends,
I am writing a simple TCP based client-server app and I would like the connection to be dropped after a certain time of inactivity and also I would like to control the connection's bandwidth. I would appreciate if someone can throw some pointers as to how this can be done.
I have tried this so far, for Timeout I am trying to do this:
sock.setSoTimeout(10000);But I think this is not the right way as this will disconnect the server from all client connections I guess. I think the better way would be to write a timer or something for each connection but I don't know how...
Any help?

sock.setSoTimeout(10000);But I think this is not the right way as this will disconnect the server from all client connections I guess.Wrong in a couple of ways.
1) That doesn`t disconnect anything. It causes a read that reaches that time in blocking to be unblocked and an exception (java.net.SocketTimeoutException) is thrown. The Socket is still just fine and can be used (all other things being equal). At any rate you then decide what you want to do after a timeout. One possibility is to close the socket because to you that timeout means it is abandoned.
2) setSoTimeout of ServerSocket applies to the accept* method. setSoTimeout of Socket applies to reads from that sockets input stream. Neither of those apply anything to all connections.
I think the better way would be to write a timer or something for each connection No setSoTimeout is correct. You will also then need to actually attempt to read something for that timeout exception to ever be thrown.
As far as the bandwidth question goes, you will need to define your goals better. Please do not just restate "control bandwidth" because that is not actually a very specific goal. Do you want to limnit the bandwidth used at one time (tricky) or do you want to limit the total bandwidth used. Either way requires some work but they are different things.

Does the MDS9222i GigE ports support 100BaseT IP network?

Hi folks,
Do the four GigE ports on the MDS 9222i and 18/4 module support a 100BaseT IP network? In other works can I connect the GigE port to a 100BaseT connection or does it have to be physically connected to a 1000Mb/s connection? I have an IP cloud that has an actual max WAN speed of 35Mb/s. Can I set the "max-bandwidth-mbps" down to 35Mb/s?
Thanks

The transciever only supports 1GE.
WRT bandwidth question: between 1-1000Mbps is acceptable.

Fabric Extender and Blade server connectivity(Cabling)

Hi,
There is lot of information available about how a Fabric extender connects to the Fabric interconnect. e.g. SFP+ ports, cabling etc.
I am bit a confused, how does connectivity happen between the blade server and fabric extender inside the chassis.
The information available only gives us idea about the possible network cards in the blade servers.
I want to understand, how actual connectivity is done between the blade servers and fabric extenders.
Is it through some cables or anything else? Please help.
Thanks,

Xserve Network Slowdown

I'm experiencing a very slow network between my 30 Mac Clients and the Mac Server. We are also using Xserve-Raid as our storage device. The 30 Mac Clients are connected concurrently to the Xserve and this 30 Macs are using Adobe applications like Photoshop to open , edit and save to the Xserve.
This week we have a significant slow down on the network that a 2 GB of data needs 3 hrs to copy from the Xserve to the client.
How do I troubleshoot this kind of situation in the network?
Is there a way to compute how much bandwidth a 1MB file consume to copy from an Xserve to a client with a 2GB of bandwidth pipe? The mac client is using a 1 GB ethernet.

The first thing to do would be to look at what's changed between when it was fast and now.
Have any new devices been added to the network?
Have you changed any network elements (e.g. changed switches, etc.)?
Are the problems experienced by all clients or just some of them?
Is it bi-directional (i.e. equally slow on uploads and downloads)?
You say you have a 2gbps link to the server. That implies you're running link aggregation. Have you checked the switch logs for errors?
Off hand the most likely candidates point to either a link aggregation issue or a duplex issue. If it affects all clients it's likely to be on the links to the server. If it's bidirectional (uploads are faster than downloads) then it's likely to be a duplex issue.
You can also run commands such as netstat -i -w 10 to get a running count of the input and output traffic stats on a 10-second basis. That will tell you if your network is saturated. High error rates could also indicate a duplex mismatch problem.
As for the bandwidth question, a 1MB file consists of 8 megabits of data.
Since a 1gbps link equates to 1024 megabits per second, you're looking at 8/1024 seconds, or about 0.078 seconds to transfer that 1MB.
Of course that assumes you're on a 100% efficient network, which is never the case. A good network without a lot of tuning would likely yield 1/3 to 1/4 of the theoretical rate, so now you're looking at about 0.2 - 0.3 seconds.

We got a new Apple TV for Christmas and it works wonderful. However, my question is this. We are on a satelitte internet system and our bandwidth is limited. Can anyone tell me what effect it will have on using up my 10 megs of bandwidth?

We got a new Apple TV for Christmas and it works wonderful. However, my question is this. We are on a satelitte internet system and our bandwidth is limited. Can anyone tell me what effect it will have on using up my 10 megs of bandwidth? If I run over the 10 mgs, the service either slows way down until it is reset on the first of the next month or I have to purchase additional bandwidth and it can get expensive.
Any information would be greatly appreciated.

If you only have a 10MB limit on the Internet connection you might as well not have Internet access and certainly should not attempt to stream anything.
If the limit is 10GB, then you will need to be careful with streaming as most video is 1-3GB for a one hour show.

DFSR performance question - high latency and high bandwidth - windows 2012r2

Hello,
first question here...
We have a pair of backup servers, connected with a 1G WAN link (290 ms latency).
I am replicating backup files (mainly SQL files) between them (one-way), for DR/BCP purposes.
a Get-DfsrState regularly shows hundreds of files in waiting state, and only 16 or so being downloaded at the same time. The system is using very little bandwidth, much less than what I have set in the replication properties (256mbps)
Is there any parameter I can tweak to increase the number of files being transferred in parallel copies?
Before you ask, the WAN circuits are fine and currently ~80% free. I can easily saturate them using other technologies (rsync, gluster, HTTP). The servers are doing very little as well (2x6C, 32G ram, lots of disks, CPU usually under 10%).
Any idea on how to speed this up? I saw some registry settings in old articles for windows 2008r2, but nothing for 2012r2.
Thanks

Hi,
It seems that the number of downloading files is not related to bandwidth.
By default, a maximum of 16 (four in Windows Server 2003 R2) concurrent downloads are shared among all connections and replication groups. Because connections and replication group updates are not serialized, there is no specific order in which updates are
received. If two schedules are opened, updates are generally received and installed from both connections at the same time.

Question: firewire bandwidth

I have a question about the firewire bandwidth in the aluminum iMacs. They have both a FW800 and FW400 ports on the back, and I was wondering if they share the total transfer bandwidth... ie: are they on the same general bus or are they both independant? I am wondering because I want to get a firewire interface for audio recording as well as an external drive, and i want to get a fw800 drive and am wondering if it would steal bandwidth from a FW400 multi-channel interface. It would only really matter under heavy load, but for example, if it should come up recording 16 tracks while monitoring 50 is a ton of bandwidth and I want to be sure before I go that route.

They are both on the same bus. But even if the 400 is maxed out there is still at least half the bandwidth left for your hard drive. For example your average FW400 hard drive read/writes at about 35MB/s and your average FW800 about 65MB/s. The FW800 interface max is about 80MB/s.

Some Questions. Server config, bitrates, bandwidth, connections

Hi. My company are trying out the FMS to establish if we will use it in the future or if we should use a cloudhost. Now I was the person put in charge of this operation(a .NET developer). So please excuse my simple questions and my lack of knowledge when it comes to flash media. I figure who better to ask then the pros at adobe that made the product. This might be a long post. I promise all help and tips I can get is highly appricaited
Setup: Amd Quad Core 2.20, RAM 1gb, windows server 2008, connections 8/4 dsl
Question one.
My memory(%) usage are on steady on about 80%, what does that mean, to little RAM or?
Question two.
Is there any Specific Server Configurations I could do to the server to make it perform better?
Question three.
What specifics should I convert the FLV files into. Are there any "Default or general" so to speak? Frames, Bitrate, Picture ratio ect.. this is where I have no idea.
Question four.
We are maybe gone have about a 1k users on this maximum. How much bandwidth does that demand?
Question five.
I have installed the FMS on my server machine. I have not done any configurations to the FMS what so ever. Now I have uploaded a test site(html) with the movie trailer from iron man 2, it is a flv downloaded from youtube. file is about 11mb.. when I run it on one 1 browser window it play good, but then i open up like 7 windows and run the clip at the same time it starts to freeze and load a lot. Is is not supose to handle more then 6 connections? I thought maybe my compter was the problem but I got a pretty good setup with 10/10 fiber, wich should be enof to stream 6 clips right?
What could this possibly be that my server can not handle more connections?

Hi Dejan-S,
You mentioned that your company is trying out FMS to see if it fits your usecase. So I would broadly like to know what is your usage like.Also which version of FMS have you downloaded?
From your question 3 I can make an assumption that your want to make available you media files for some one to view them by streaming them using FMS. On this assumption I will attempt to answer your questions:
1. My memory(%) usage are on steady on about 80%, what does that mean, to little RAM or?
Yes a higher RAM would definitely help, we recommend 2GB at the minimum. Also you could tune your server by using the SERVER.FLVCACHE_MAXSIZE of fms.ini file at FMS Root directory/conf. You could set it to a higher value provided you have sufficient RAM so FMS would use this space for caching the streaming content and serve your video on demand usage better.Typically you could try setting the SERVER.FLVCACHE_MAXSIZE to 1/4th of your server's RAM size.
You might have taken a look at http://www.adobe.com/products/flashmediainteractive/systemreqs/
2. Is there any Specific Server Configurations I could do to the server to make it perform better?
Are you using the vod application at FMS Root directory/applications for streaming? If not you could try using that app and also take a look at the configurations made in the Application.xml(located in vod directory) there which could act as a guideline for fine tuning your server.
The section name "Tuning server performance" in the flashmediaserver_3.5_tech_overview.pdf at FMS Root directory/documentation might also give you some insight into this area.
3. What specifics should I convert the FLV files into. Are there any "Default or general" so to speak? Frames, Bitrate, Picture ratio ect.. this is where I have no idea.
A lot of that would depend on your final deployment(the hardware resources that you are allocating) and if it will be able to handle the higher bitrate files. The frames and picture ratio too is your choice on how much crispness you want to bring to your video files.
Also wanted to let you know FMS supports MP4 format as well which means you could use H.264 and HE-AAC codecs in your media files.
4. We are maybe gone have about a 1k users on this maximum. How much bandwidth does that demand?
It would depend on factors like how high a bitrate video files are you streaming and if all the all the 1000 users are connected to FMS server and streaming at the same time. It would be tough to give an estimate just based on number of users.
5. I have installed the FMS on my server machine. I have not done any configurations to the FMS what so ever. Now I have uploaded a test site(html) with the movie trailer from iron man 2, it is a flv downloaded from youtube. file is about 11mb.. when I run it on one 1 browser window it play good, but then i open up like 7 windows and run the clip at the same time it starts to freeze and load a lot. Is is not supose to handle more then 6 connections? I thought maybe my compter was the problem but I got a pretty good setup with 10/10 fiber, wich should be enof to stream 6 clips right?
What could this possibly be that my server can not handle more connections?
I think it's your client machine which is unable to handle so many browsers playing video at the same time.So I guess you could try opening the browsers on different client machine and see that you are able to get the ideal experience.
Also if your use case is video on demand, then you could also make use of the Edge-Origin deployment of FMS where in you make use of the FMS edge server's capability to cache streaming content and serve users seeking the same content instead of fetching it from the FMS origin server all over again.
You could take a look at the flashmediaserver_3.5_tech_overview.pdf at FMS Root directory/documentation and look for "Deploying Edge Servers" to get more idea.
I hope this helps.
Thanks
