• MPIO - iscsi - ARE links/Ops / s

  Am I correct in saying get;

  iSCSI MPIO will not increase your IOPS / s for a given machine, unless your ethernet connection is saturated?

  MPIO does not increase performance per say, but give you a "big pipe" for several virtual machines on?

  My scavaging on the net I find there are TWO ways to enable MPIO for you.

  (1) Add second Teddy (physical nic), assign the nic to your switch. Create a second VMkernal, substitute blanace loading options and set an active nic by vmk. Add the two vmk to the iscsi HBA, enable repetition alternate on the management of the paths to the data store. Shows that I have two paths.

  or

  (2) add the second bear to switch, allow the two bears will use the unique vmk. storage system, create two targets that map to the same LUN. Shows two paths.

  Does it matter which way MPIO is configured as it shows several paths?

  Out of curiosity I configured esxi using the first way to configure MPIO, then created a second target with the same number of LUN on the storage. ESXi shows that I have 4 paths to storage. A path is a link right? so 4 paths would be unnecessary, at least that I had 4 links and very high demand?

  I read that it takes about 14 000 iops to saturate a gigabit link. Does this mean that since my storage system cannot achieve worldwide real scenerio MPIO is a waste of time?

  Thank you to everyone who takes the time to communicate with me!

  You are confused of serveral things in your argument.

  Let's first start IOPS / s. To make an e/s of the mechanical components are involved on a disk and the number of IOs can run a disc is therefore very limited.

  For this example lets assume that a disk can do 100 IOs (some less, some more do) and that you have 10 disks at hand. This means that your storage hardware can make 1000 IOPS / s. If you invest in a storage Bay real intelligence of implementing adding caching and controller you can get you more out of your drives as long your load is a good target for caching, but I don't know this option.

  How to tie up your storage space (FC, iSCSI,) at an ESX Server direct changes nothing on the number of the IOPS / s your disks can do a lot.

  However, it influences the bandwidth you can achieve.

  Suppose that your consumption of storage is a WIndows NTFS machine. NTFS uses a typical 4 K block size. That calculates to a maximum block size of 4 K x 1000 = 4 MB bandwidth. Which can easily be done on a 100 MB link and you will see this flow if your consumption is doing sequential i/o only.

  Now suppose that your ESX Server has a VMFS formatted with 1 MB (512 GB). While loading fully your 10 discs, you can reach 1 MB x 1000 = 10 GB.

  Again, this is possible if your VMFS was only sequential writing which he did not.

  When you run virtual machines VMs operating system will write to his type of typical files (i.e. 4 K on WIndows) and so the underlying VMFS will buffer a bit in its own cache and access discs in shuffle mode. Thus, you should expect a lot less bandwidth used. It many cases a single gigabit link will not be saturated.

  MPIO is a function which can reach:

  -Path redundancy

  -Additional bandwidth and IOPS / s in some cases

  If MPIO can also add to the number if IOPS / s depends on the type of controller you have on the side storage. If you have a single controller with ports different frontend IOPS gain / s should not be dramatic. With several controllers, indivdual caches and mutual paths to the disks that you can achieve additional IOPS if you get a good cache reference rate.

  How many different ways you can use with MPIO depends on what can make your storage space. What is a passive connection active? Reach you reduncancy but no INCREASE in the Ops / s or bandwidth. Only an active-active array will increase the bandwidth and, possibly, the number of IOPS / s you can achieve.

  With ESX4 you can use up to 8 channels, if it's something your taken storage array supported by parallel controller access.

• understanding DBMS_RESOURCE_MANAGER. Output CALIBRATE_IO

• series-usb lag with other usb devices

  I don't think that the title of this post fully captures the problem I am facing, then, let me explain a little more.  I'm trying to interface with a lot of devices in LabVIEW, two of my machines are built to order and use adapters of RS-422 to USB and another 4 devices are devices of BEDS that use USB.  So, all of my devices are connected to my computer via USB (via two 8-port external powered hubs).  I basically read data from my custom built devices, then using this data to control 4 devices for the use of cots.  My custom devices are running at 3.6 Mbit/s and reading data from them with nothing else connected works very well. The problems begin to occur when I begin connecting devices COTS.  I have connect and try to interface with them, I start having problems contacting my two custom devices.  Specifically, one or two devices from start to lift saturation errors until the data flows become unnecessary.  In addition, I also sometimes experience what is described as a ghost mouse problem.  My mouse starts moving and clicking on its own (opening programs, windows resizing, etc...).  I guess that's probably the USB driver listens outside.  The only way to stop it is to disconnect all the USB devices on the machine.

  Someone knows something like that before?  Can anyone suggest how disturbing these questions?  I'm kind of at a loss on what to do?

  I have no real information on your specific problems.  But, your computer will probably several USB controllers and you try to plug your controllers separate hubs to divide the load to the usb.  It might take a bit to search a manual or online to see which ports belong to which controller.

• How to download data from test to SFIS via webservice

  Hello world

  I need to download data from test to SFIS via the webservice and the service will return the result., but I have no idea of web service.

  I need to submit as soon as possible. If anyone can write it.

  You start by the seller. How do get the data? HTTP put and get operations? Customer HTML screws can do that.

  Which makes the network based thing you are trying to send your data? It would be useful to know. You see SFIS, MY or LIMS are terms all very generals who actually communicate very little useful information (see also: "buzz words").

• I need autoscaling on a graph XY to ignore a parcel

  I'm doing the autoscaling to ignore one of the three locations on a XY Chart.  My program trace a set of data points, that approach and exceed a critical level.  My chart has three parcels: under the limit points are green points, points above the limit are red dots, and the limit is a horizontal dotted line extending between two points.  Initially, endpoints of the line have been established in the vicinity of the x-values of data.  Autoscaling worked very well, of course, but the line analyses as well as the data they are traced.  This limit is a fixed value, I like the line to stretch completely on the screen and stand still.

  To this end, I put endpoints beyond the limits of the x values.  Now, auto-scaling of the tracks with the endpoints of the line and the actual data are compacted in the middle of the graph.  Is it possible I can forward the autoscaling only with data points and ignore the line, or is the best option, just write my own code, autoscaling?

  Thank you!

  You could wirte your own automatic scale, but I think is easier to do something to change your horizontal line of a parcel of a cursor. You can use the list property of cursor or active (the control graph) the cursor property to control positioning and the color of the cursor, and you have not to worry ever its end points (there no).

• Color Laser Jet MFP M177fw Pro: Printer is not recognized by the devices.

  When connected to a computer via the usb - B to usb at the back of the device connection, computers do not get a signal telling them that they are connected to anything. The computer windows 7 behaves as there is nothing plugged and a Mac running 10.9.5 simply gives the error message "the disk you inserted is not readable by this computer. When I try to download the drivers for the device manually, the installation of HP can't find the printer in the devices, even when it is plugged. Both computers have been restarted, several cables (who work for other printers and are located in the length of HP limit) are the same exact behavior.

  Solution has been found, windows 7 update, but a driver do not go along, while some things have worked when it is plugged. HP partner, effects no side windows just weird.

• EA6700 Cup internet high speed two

  Hello

  I just sign up for Time Warner internet Turbo, which promises speeds of up to 20MBPS down and 2 Mbps upward.  I use a Motorola SB6141 modem and a Linksys EA6700 router.

  When I test the speed using Speednet or Speakeasy speed test clean of TW, my downloads are constantly between 15-16 Mbit/s so that the rock download at speeds between 5-6 Mbps.  So although the download speeds are not advertised, my download speeds half are announced.

  I removed the router from the system and directly connected to the modem and tested again several times. the upload speed has remained in the range of 5-6 Mbps, while the download speed went to 33-34MBPS constantly.

  So it's the router.

  I reconnected the router and tried different configurations, the most fundamental of which was connecting to fixed my computer to a single port on the back of the router without other connections and wireless off.  By download speeds back to the range of 15-16 Mbit/s.

  I also replaced the Cat5 cable between the modem and the router.  No change.

  Any ideas?

  

  Was when you did the test directly connected to the Modem via Ethernet? If it was have you done the same test connected via Ethernet to the router?

  If your tests for both were made via Ethernet then my tests with Linksys hardware is probably this QOS\Prioritization or the Parental control is activated.

  For wireless WMM support must be enabled.

  I recommend disabling SimpleTap.

• Parental control blocks WMA format audio playback of the site on the list of allowed sites

• WET610N Bit rate issue

  Under the 'Status' and then 'Wireless Network' menu, there is a "flow" indicator.  What is - it really tell you?  What is the potential flow based on the quality of the signal and the network that you are connected (for example 300 Mbits/s to N) or is it flow based on current usage?

  Here is my experience.  My WET610N reports static 13.5 Mbps bit rate if there is no traffic.  However, if I start downloading something on the device connected to the WET610N then the bit rate jumps up to 162 Mbit/s.  Is this indicator totally * beep * or is there actually something worthwhile for us about the performance of WET610Ns?

  WET610N

  Firmware - 1.0.0.3

  Connected to: WRT610N, 5 GHz, N-channel only, width channel Standard of 40 Mhz, wide channel 159, 161, WPA2 Personal.

  Thank you

  The WET610N has rate limiting, depending on your network traffic.

  When there is no traffic, it will come down to the base rate of your router (in this case 13.5Mbps).

  Once you start the stream, the rate will increase.

  If you want a good measure of rate, try to download a large file from a local computer and watch this screen.

• No idea how I can follow all currently open files (or windows) to a file text or other sort of newspaper? Something similar to the Applications tab in the Manager of tasks, but with a path

  I am interested in creating a batch file or executable that will keep track of all of the currently open windows (files and applications)

  so that when Windows restarts I can more easily return to what I was doing before.
  This can be done either by connecting each operation on the file - open and remove items in the list when an item (file or window) is closed (logging only at this time here)
  , or by checking every 5-10 seconds that windows and files are currently open.
  I tried using TaskList, and OpenFiles to it but cannot do things, plus those also do not provide a path to open files - I want to keep the paths so that the items can be recovered (reopening) with a single click.   Any ideas how to do this?   I use Windows 7 Professional.
  My idea is to have the possibility to go back to all that I was working on, without having to memorize the list...  It is very useful for people who keep a lot of files and windows open most of the time, especially if for some reason any Windows crashes or stops the case (e.g. restart after an update...).    MS Office products can do it (by saving temporary files and allows you to recover if the program was not closed properly), a Web browser can do (keeping a story and using the session management)-why Windows can't do
  ?
  In addition, if there is such list of open windows and files then it might be possible to keep also some history and ' files/windows' recently closed, similar to how Google Chrome can show recently closed tab.
  The application that I'm developing (for my own personal use, although I would offer it to someone else) will be:
  -keep a history and a current list of open files/windows, including a path for each file opened.
  -Files/windows closed are removed from the list "now open" and moved to the list of "recently closed", which has a maximum length.
  -file/window close operations should be associated with the user control. Otherwise, opens the files that are closed
  by Windows when the judgment is no longer will be identified as open.
  -an option would be to ensure, somehow, that this request is always closed during a regular shutdown process first.
  -Another option is to simply assume that there is no problem, if Windows broke down, and that the user is reminded to close the application before you stop.
  -Another option is to have the traceable list, a user can go back a few steps up a point until Windows began to close.
  -Another option is to have the "last sitting" identified as, for example 2 minutes before closing, while keeping a list of items opened after that date.
  -list "recently closed" items that are too old (have been pushed to the bottom of the list and beyond of the length limit are moved to history.
  -l' history can be defined for a limited time or can be cleaned manually or automatically (periodically), or we can set a limit on the length for the history list.
  * the application/batch/executable is located in the Windows startup folder and it:
  -is launched at Windows startup
  -after start (automatically or manually) will display a dialog box containing a list of the items that were open before windows stop - see Creating session above.
  -user can deselect items in the list if he or she does not want to open them. "Uncheck the items of list moves to the ' recently closed" list or history.
  -by identifying which items are not kept, or simply to keep everything, the user clicks on a single button and the application opens to all items that are always enabled.  To avoid slowing down the system, an option is available to open files, in which case a flow can be set.  Defining a priority list, it is also an idea.
  If you think you have a good idea for this or want to work on it with me, please contact me at * address email is removed from the privacy *.
  If you are able to do it yourself, let me know.

  It all sounds very complicated for me, I wish you well in your efforts.

• Computer Xbox 360 Media Extender and Windows 7 do not 'see' each other

  I had been successfully streaming from my PC content (32-bit) of Windows 7 to my XBox 360 (60 GB HD) since late 2009.  They are connected by Ethernet 100 Mbit/s via a 100 Mbps 3Com switch unmanaged and a Siemens ADSL gateway/router with a switch to 4 ports.  I use not media Extender functionality every day.  Its more like I use it for a week (after I have come back from vacation and want to see my photos and videos), so I use it for about 2-3 months.  Everything I do is press the green button on my remote to turn on the XBox and connect to Windows 7 Media Center.  I don't even bother to turn on my PC like the XBox, it wakes up for me (love it!)

  I modified it used successfully in mid-December 2010, but when I tried to use it again on 28 Dec XBox stated that he could not find the Windows Media Center computer.  I ran the diagnostics of XBox with no luck.  The XBox can detect and connect to my laptop (also under Windows 7 and is connected via WiFi), but it does not detect my PC.

  On my PC, the Extender both in the window "Devices and printers", in Media Center, presented with an exclamation icon and a message saying that the Extender is set up but can not be found.

  The only thing I changed on my PC since the last time the Extender has worked:

  (1) I removed the password on my user account

  (2) I turned off password protected sharing

  I noticed that some security updates have been implemented as well.

  Even if my laptop (that the XBox can still detect) was already configured with no user password and no password protected sharing, I reversed manually these settings on my PC.  This did not help.

  I tried an article that describes the removal of the certificate and add the Extender - no change.

  I tried to disable the firewall of Windows (the only firewall installed on my computer) and Microsoft Security Essentials, as long as my agent for LogMeIn - no change.

  Fortunately, I still had a restoration which dates back to the changed Extender worked, and restored at this point.  The Extender has worked once more... for a few weeks.  I thought that the problem would be back because I didn't really know what caused it in the first place.

  When the problem is back, I read a lot of articles, including those on this forum.  Some suggest specific problems with Asus computers equipped with software installed at the factory, creating a problem, or fingerprint scanners or memberships of domain.  None of them apply to me.  My PC worked loyally with the XBox as I first put in place in late 2009.

  So I went more drastic.  Two weeks ago, I rebuilt the PC from scratch.  I have not yet installed as much software as it was originally - just the basics like Office, Acrobat Reader, Picasa, iTunes, Java, Flash, Google Earth and LogMeIn...  Of course the Extender reworked... twice.  The next time I tried to use it, it wouldn't.

  I tried several restore points - this time, none of them brought the feature.

  Of course, thanks to all this the XBox can still detect my laptop which has also received updates from the Windows Update service (if only my laptop could host all of my pictures and videos...).  My laptop also has the same software, including the firewall of Windows, Microsoft Security Essentials, LogMeIn, etc...)

  This makes me think of something on the Windows 7 PC is blocking incoming or outgoing (or both) types of communication to the XBox.  What kind of diagnostic tools could use to figure out what is the cause.  If I have to sniff the network, what I'm looking for?

  I have reviewed the issue of abandonment and just buying a NAS that supports the XBox Media Extender, but:

  (a) none of the products in my price range offer the features AND performance, I want to

  (b) why should I have to?  He worked for nearly a year, and this feature must be a utility "solid."

  Thank you...

  Hi Umesh,

  Thank you for you answer.  I had already read the article you recommended, but I saw her again (especially step 3) to ensure that I had done everything I could.  There is no recommendation in this article that applied to me, or had already been tried.

  I took another look on my laptop that the 360 can detect and noticed that he was not part of a homegroup, but offered to join the homegroup organized by my Media Center PC.  I was surprised because before the reconstruction and after reconstruction, I don't remember setting up a homegroup.  Of course a homegroup has been partially install (he said my I had no libraries selected for sharing).

  I left the homegroup, and this restored PC allows my Media Center to 'see' the XBox 360 media extender.  My problem is solved (for now).

• Installation on new Windows10 Photoshop7 computer with 2 to and 16 GB

  I use Photoshop7 for years and I'm comfortable with it. I installed it on all new computers because I get them because I got it and it has always worked well. Now I try on my computer last new, which has Windows 10, 2 TB and 16 GB of Ram, and all I get is an error that says: "Could not initialize Photoshop because the"scratch disks"is full."

  I read through many articles, forums, etc. All of them seem to be of the spirit you need to partition your drive hard to make it work. I am not all that computer savvy and don't know, I want to do this (not sure how that impacts my space). In addition, it seems that most of the responses came from questions that came years ago or on different versions of Windows. If I put it out there again. Adobe has created something to solve this problem? Is there a way around it?

  I tried to download the trial version Photoshop to online, but for this simple user, this new and improved program is much too complicated (and expensive). I don't want to pay a monthly fee to use it either. I just wanted to be able to use my old version on my new computer. Is there a way?

  Thank you in advance.

  Photoshop 7 cannot see drives over 1 TB see this thread for an explanation and a few ideas.

  In one, I run, I changed the "Connect-VIServer-menu" to simply plug the vCenter Server I use. I also changed line 16 to 'Get-ResourcePool' since there's not enough pools to make this work.

I know it's probably something simple that I'm just missing.

  I like the length of time that this script uses the information. If anything, I don't want to go back to the suite to get a better idea of what the actual maximum number what is / was. It is also necessary to have the columns for information (as he shows). If we are to refine for which metric is present, I would be ok with just having the IOPS numbers / s max in the table.
