• Fault tolerance limits

  I would like to implement fault tolerance for a couple of our virtual machines, but I was reading and I have a few questions.

  1. it is said that you must have 2 vmkernel NIC dedicated to fault tolerance. Can it be shared with vmotion NIC?

  2 FT does not support SMP. Is this still the case? We lack ESX 4 Update 1.

  3 FT does not support snapshots. VReplicator allows us to reproduce our vm. This creates a snapshot during replication. That are not or not be possible?

  Thank you

  1. you need at least 1 vmkernal NETWORK card dedicated for FT (or a new VIRTUAL local network, if you have 10 GbE) there is a lot of traffic that will be flowing for this shot

  -You can see a design on my website http://kendrickcoleman.com/index.php?/Tech-Blog/vsphere-host-nic-configuration.html

  2. Yes. You can't have FT w / 1 vCPU VMs currently. But if you have some awesome Nehalem procs, you may only have 1vCPU for your boxes of criticism

  3. they will fail. The snapshots are not possible on the VMS FT. As a result, backups will not work. I know it's one of the huge problems of scenario best IP, Setup a script to make a virtual machine out of FT, run the backup, and then select FT. A lot of work for a final result.

• NEITHER 9852 communication with fault tolerant CAN materials

  Hello

  I have a cRio 9074 and recently bought a module NI 9852 2-port low-speed/fault-tolerant CAN.

  It's my first attempt at network comms in cRio and I realized that none of the devices with that I want to communicate are immune to failures and fault-tolerant physical layer requires different endings to 'normal' high speed MAY (immediately after I broke the seal on the box, of course!)

  Is it possible that I can configure the physical layer for this configuration to work reliably (alebit to)< 125="" kbps="" and="" with="" no="" fault="">

  Kind regards

  Chris

  I'm sorry. The low speed / transceivers and breakdown-tolerant high speed MAY use different communication protocols.

  HS CAN is recessive when CANH and CANL are both to nominally under 2, 5V. It is dominant when CANH is 3.5V and CANL is 1, 5V.

  LS CAN is recessive when CANH is a CHANNEL and 0V to 5V. It is dominant when CANH is 3.6V and CANL is 1.4V.

  You can see that they are almost the same for the dominant, but different for recessive. In addition, the sequence of end between two buses is different. For a HS-bus, you usually resistance 120 ohm between CANH and CANL at both ends of your bus.  A bus of the LS, you have a terminating resistor separate for CANH and CANL (for RTH and RTL).

• Message: This device can perform faster if you connect high speed USB

  Hello

  I have a laptop Toshiba Satellite 2009 of Vista.
  I just bought a multimedia design Memup Feel of the disc hard 500 GB.

  My concern is that when I connect to my PC, I have the following message:
  + This device can perform faster. USB devices can be faster if you connect to a USB 2.0 high speed +.
  + To get the list of available ports, click here. +

  Then I have a list of ports in bold, but I don't know what to do with.

  How to solve my problem?

  Thank you

  Hello

  Are you sure that your laptop is Satellite 2009?
  I put t know this model of laptop.

  But I know that this error message; This message appears if you connect a USB 2.0 device to a slower USB port; That is, USB 1.1
  But I think that your laptop supports USB 2.0 ports either TI problem disc external HARD s or the issue of USB drivers
  Try updating the chipset driver you can also delete all the USB controllers and hubs in Device Manager ports. Restart the unit. After restarting again the OS would recognize all USB ports.
  Then try to reconnect the USB HDD

• How can I add a USB host controller high-speed to my PC?

  My OS is windows xp home edition. I get this message that the HI-SPEED device attached to Non HI-SPEED USB Hub.

  The USB Composite device is a USB HI-SPEED device and will function at reduced speed when plugged into a port not HI-SPEED.

  There is no host controller USB HI-SPEED installed on this computer.

  Recommendation: You add a USB host controller high-speed on this computer in order to get maximum performance.

  So, how can I add this USB host controller high-speed to my PC? Is - this material I must add and physically install to my PC?

  As always, any help is greatly appreciated.

  Thank you!

  Hi Drake,

  Review the devices USB connected to your PC and make sure that there is not a USB 1.x device connected to the same USB HUB (front or rear).  USB 1.x devices will cause the USB HUB at the bottom shift to 1.x speeds.

  You have an old PC (2002), it is possible that your PC does not have a USB HUB 2.0.  In this case, you need to install a USB PCI adapter card.

• If I have two modems in the same office... windows xp can combine two connections at higher speed dial... my question is can I do the same thing for the dsl if I have two lan cards?

  Hi cliffwho

  You can fill with connections to the LAN. However I recommend you read this first to understand what it is that you do. I hope this helps.

• I pay to 30 Mbps high speed Internet, but I can't reach anywhere near that.

  Need more speed!

  I pay to 30 Mbps high speed Internet, but I can't reach anywhere near that. I am an intermediate user of computers, so I know the basics to determine problems on my laptop. My laptop has Windows 7 and is a Dell 1545 Inspiron. I was told I may have to buy a card N-router, but when I checked the info on what's in the computer it says that I have the ability to achieve 54 Mbps. I'm confused... Please help...

  Hello faerygyrl34,

  At home, I have a connection to 25meg down and I see usually 2 to 2.5 MB download speed when downloading files via either wired or wireless.
  It was my normal rule you divide by 10 connection speed and is normally your download speed in performance in the real world.
  This has to do with the difference between MB and megabits. A megabit is about one-tenth of the information of a megabyte.
  Internet provider is advertising 30 megabits, but you're going to download only to 3 megabytes.
  Who is? It can be quite confusing.

• Can I use a connection high speed in safe mode?

  I have something to do in safe mode with internet connection, but I only have a Modem high speed and the computer does not detect the modem how can I use my broadband in Mode safe mode pls help me

  This is not surprising.  For networking Windows in safe mode uses a limited set of common standard network built into Windows device drivers.   It is the basis of the concept of safe mode which can be used to deal with 3rd party driver problems.  Windows does not have a driver for each possible network card / device.  Mobile Broadband are exclusive and very probably not be supported with a native Microsoft device driver.

  What is, is that you need to do in safe mode with networking?  If it is really essential, maybe you could do it on the site of knowledge where you could plug their router.

• What can we fault-tolerant?

  Hello

  We have a vSphere ESX Server with 7 virtual machines running in production on a Proliant DL380 server environment.

  Now, I would buy a second DL380 Server a vSpehre of a second license to create a fault tolerance with two servers. So if the vSphere Server1 falls down, second Server2 catches up with the work of Server1.

  Should which product I have for this scenario? Should we the server vCenter to do this? And if so, I'll have to buy a third server only for vCenter?

  Hello

  that you read here

  for pi, you must finally advanced editing.

  Then you Norman to have a license for every host ESX and vcenter advanced editing.

• You can install vCenter as a virtual machine with fault tolerance

  The benefits of having vCenter as a virtual machine are features such as HA and snapshots, is there a problem with having a fault tolerance enabled on a virtual machine that is the vCenter server to manage fault tolerance?

  He couldn't see in the documentation for fault tolerance limits

  Well...

  vCenter lists 2 CPUs as required and FT only works with one...

• WiFi unstable and slow Internet high speed

  Hello world:

  Recently, I am facing a problem of unstable wifi, slow speed of the internet of my macbook pro. I hope someone could help me with my problem.

  
  

  Symptom:

  Internet mainly speed just unstable using a wifi connection. (no problem with wifi connection self and my wifi suddenly grave would not be)

  Example:

  • FaceTime with my friends and the connection would suddenly abandon or images & audio gets fuzzy.
  • Videos in online streaming and suddenly occurs buffering.
  • Download file of software update iPhone via iTunes, the speed is slow, he needed to take 2 h at the end and later on a window display "cannot download and check your internet connection".
  • Suddenly cannot open websites like site apple.com, google.com. Sometimes it will take more time to open Web sites.

  Hardware and software:

  MacBook Pro mid-2009, OS X EL Capitan 10.11.5

  ISP: Cox, 50Mbps

  Modem & router: Netgear N450

  Test:

  Turn off my wifi and connect my macbook pro with modem & router with cable, internet high speed is stable and fast. Internet speed download speed test result display is of around 60Mbps, download speed is around 8Mbps. And I tried streaming using the connection cable, there was no buffering.

  I already tried the possible Solutions:

  • Restart the Macbook pro and restart Modem & router: will not work. I mean the internet will be very well at first, but later would be unstable again.
  • Reset Wireless Modem & router and change channels: useful, but not completely solve the problem. After you change the wireless channel, I tested my internet speed and the result showing 20-40Mbps (slower than 60mbps) speed download. Sometimes, the result will be like 6-8Mbps and sometimes it will be 60Mbps. If its unstable.
  • Wireless diagnosis: result indicates connection is good.
  • Called my ISP provider: they checked and said all right.

  
  

  Other Questions & details:

  • The internet is ok for most of the time. But when all of a sudden I can't open site or I can't download and streaming & FaceTime at normal speed, his frustration.
  • I thought it might be related to my hardware since its an old macbook pro. I can't run Apple hardware test because I don't have the installation disc more and my macbook pro is very old. Is it a third party software that can perform the test hardware on mac?
  • My wifi used to be very stable and I don't have to worry. Just for these last two weeks.

  
  

  
  

  I really appreciate your time and help! Looking forward to any reply!
