• Switches Cisco stackable, 500 and the consolidation of NETWORK cards

  Am looking using the stacking and NIC teaming to create redunancy for user access to servers. What I think is becoming 2 switches SG500-28 and set them up in a stack which appears as a logical switch. Now on the servers I have re 2 network cards to be a team so that they appear as a logical interface 1, perferably in an active/active configuration using LACP. In this team NIC take 1 member of the team to either switch B, so that each Member of the team is on separate switches.

  Givent the scenario:

  (1) who will work with the switches of the 500 series? The switches is that their price point is perfect for my client.

  (2) in addition, the connection of the battery will be there also needs to be a GAP between the switches or the connection of the battery is also data traffic?

  Hi Robert,.

  (1) I don't see any reason that this would not work as desired. There are the requirements by doing a SHIFT but being on the same physical switch isn't a.

  (2) with the switch of SG500 line, you have a few options for up/down the link between the switches to the battery, it depends on the model. Each of them supports 1 G up and down links with copper. The switches are then divided and support 5G or 10G mini-gbic down links. There is not currently an options trolling battery links.

  Let me know if that answers your questions!

• core VM and the consolidation of NETWORK cards

  Hello

  By default, VM network ports group is associated with two vmnic and the management ports group is connected to one vmnic. Is there a reason for this?

  

  This isn't really a default configuration.

  By default would be vmk0-> vSwitch0-> vmnic0 - just an uplink to the default vSwitch.

  It seems that someone is gone, has added the vmnic1 to your vSwitch0 and configured the active adapters / Eve / unused. To clear the reason for this, you have to love the person responsible for this change.

  Could also be a config after installation automatically, depends on how you installed your ESXi host.

• Help with the consolidation of NETWORK cards

  I have a box blade with several blades attached to the switch blade.  Read the doc and experimentation, it seems that with the parameter 'link status only' blades will never be aware of the problems of network beyond the connection between the blade and the local switch.

  For example, I have install NIC teaming with:

  Nic0 = active

  NIC1 = standby

  By causing a failure on the way to nic0 (beyond the switch), I lost the connection and the day before not to enter in action.

  Question 1:

  When you never use (is an auxiliary card not almost useless)?

  Question 2: (I really need an answer for this one)

  Assuming that you use Active/active instead of the active / standby * and *.

  You have a network outage where esxi is not aware of the outage * and *.

  Everything which load balancing option you are using happens to try to send down the wrong path...

  The load balancer alogrythm keep trying this wrong way forever and never try the other path?

  NB - I know hadou "beacon probing" option but most ay docs to not use it.

  Thank you

  Hello

  What blade case are you help and who past did they? Various switches have a function for example Cisco Monitoring of State of the link that allows to disable contactors blade interfaces internal fail all the external interfaces. This means that you should never get into a position whereby the upstream link failure will go unnoticed.

• Network [vSphere 4.1] load balancing and failover vMotion

  GoodMorning everyone.

  I have some doubts about the configuration of the network for vMotion in vSphere 4.1

  I know that I can activate a single portgroup VMkernel for vMotion on the single host, but can I have this portgroup in a vSwitch with two or more physical NIC attached.

  Currently, I managed to have a vSwtich with vMotion and management of trade wth two NICs (see attachment).

  Both NICs works very well with the recovery for both exchanges.

  I would switch to a vSwitch with multiple network cards and I have some doubts.

  It seems that I could configure it... but the load balancer for vMotion supported on vSphere 4.1?

  And also, have the protgroup of vMotion in a switch with several network cards, is there a way to check what physical nic is currently used by vMotion?

  I am currently under a license from the company.

  Thank you all for your help.

  vMotion for vSphere pre 5 does not support Multi-NIC, in vSphere 5, you can configure several VMKernel enable vMotion and select different Nic Active and load balance between the two vmnic, but unfortunately not in vSphere 4.x

  For the management of ESXi, if you set active on both network adapters, you not to cross any active advantage / standby because it will only use on vmNIC, unless there is still a failure... but 1 vmNIC just because bandwidth is usually not a problem for the ESXi management only.

  So the answer: upgrade to vSphere 5 for multi-nic vMotion and don't worry ESXi management as an active NETWORK card is more than enough bandwidth,.

  Here's a YouTube on the Multi-NIC vMotion http://www.youtube.com/watch?v=7njBRF2N0Z8 configuration

• Load balancing across the NETWORK interface card

  Hello

  Our ESX Server's NIC six, two for SAN, one to the dedicated Service Console and three for the virtual computer LAN traffic. I noticed one thing look in the performance tab in VC, is that all LAN traffic seems to go on one of the three the NIC and the other two are practically inactive.

  If I look at the network configuration for the vSwitch those with three cards network, grouping of NETWORK cards is set for 'road based on the original virtual port code '.

  Can anyone advise how to get a more 'democratic' usage of the three NETWORK adapter?

  
  
  As seen on http://www.eqlforums.com !

  How many virtual machines you host? With the load balancing algorithm you have selected (default), traffic is balanced to the vNIC level (i.e. all traffic from a given vNIC always through the same bear). This is the case for all, but the IP hash algorithm, which requires you to 802.3ad static port aggregation on your pSwitch. In most cases, there is no need to worry about the use of bear - if it's a GbE NETWORK card, you're probably not close to push the limits.

• Difference between the Port ID of the load balancer and MAC?

  There are three strategies for load balancing in 4.0 (one more now in 4.1):

  Function hash IP route

  Route based on the originating Virtual Port ID

  Route in function interference source to the MAC

  I think that I understand perfectly the "IP hash" and how it relates to switches, but what really is the difference between 'source MAC' and 'Port ID'?

  They seems both to do something very similar, which is attached a VM to a physical network card. Why someone should choose the CBC MAC and why the Port-ID? Is there a difference in the way that traffic will extend that could be interesting, when you do a design?

  Hello.

  To simplify, to really all boils down to the formula used to distribute traffic natachasery.

• Retired HP Pavilion a6000n PC and can not find the driver for Network Card card do? Download Driver?

  Gradient of the Visa OS came with the PC for XP.  Installed new HD and partitioned drive so there is no pass file.

  Thank you.

  Thank you very much... which seems to do the job for letting me use the network card.  Once I installed the chipset you me too, my IE was able to get the net.  The only thing that happened that I wonder about, what I choose to accept or not something RAID, which I accepted and it seems to work with one small annoying side affect: I can't get Windows Update to run.  I get this error: 0x8024400a and I spent literally hours looking for and trying different solutions, which none have worked. Do you think that there is something that would change this Nvidia software which would cause that?   I get out to the internet OK and can go to any web page.  It runs a bit slow, but I thought it might be because I'm using a newly installed Win XP and it has only 2 SP.  My next step in getting this thing to work was to run Windows Update and anti-virus stuff set.   Any way, thanks again for your help.

  Hello

  To me, it seems that you used is not compatible Wlan module.
  But I found this thread:
  http://forums.computers.Toshiba-Europe.com/forums/thread.jspa?MessageID=79237

  A user was unable to activate new update Intel Wlan card.
  According to some information, its possible to enable the Wlan card by covering pin 13 on the wireless Mini-PCI network card.
  But to be honest I've ever tried and I would use this workaround with caution.

• Reinstalled Microsoft Xp professional and have now no network card

  I reinstalled Microsoft Xp professional due to problems with the computer. Now, I don't have access to the internet and the network card drivers are not displayed

  Yes.

  No operating system comes with hardware devices for each device drivers ever fact - although they come with those generic that make things "work" a bit.

  You will need to understand (invoice, speet spec for the brand & model of computer, web search, opeing computer and PSP on parts...) What are the devices and making them and to download the appropriate drivers (probably on another machine and transfer it with a Flash DRIVE or CD/DVD to the machine in question) and get them installed.
