• Correct settings to use Smart Connect and load balancing?

  Hi guys

  I have a question, the answer of which I was not able to find explicitly, so I hope a quick fix OK / not OK for you:

  I would use tri-band technology provides the R8000, i.e. to activate Smart Connect / load balancing. Is - it only works Ghzs 5 band, or the router can also connect clients on the 2 Ghz bands?

  If this is true, then I need to give the strip of 2, 4 GHz the SSID the same 5 Ghz band, correct?

  Otherwise, if it only works in the 5 Ghz bands, I could keep the SSID distinguishes?

  Thank you

• What load balancing algorithm using the LRT224?

  I was wondering if anyone knew what algorithm of load balancing the LRT224 use since I can't find it anywhere and the telephone support line does not.  It is very similar to the RV320 of Cisco that uses Weighted Round Robin, but I don't think that the Linksys uses this algorithm because it includes speeds of bandwidth unlike the cisco that does not work.  and if anyone can also check that this unit doesn't package base rather than load balanced session load balancing.  as much information as possible would be appreciated!

  The standard of the LRT load balancing is alternated:

  Example:

  1 TCP connection to website-online WAN1

  2 TCP connection to website2.com-online WAN2

  3 TCP connection to website2.com-online WAN1

  4 TCP connection to website1.com-online WAN2

  If you enable the feature (recommended) sticky load balancing load balancing is done on a base per session instead of the base of the connection.

  Example:

  1 TCP connection to website-online WAN1

  2 TCP connection to website2.com-online WAN2

  3 TCP connection to website2.com-online WAN2

  4 TCP connection to website1.com-online WAN1

• How to configure das MD3200i load balancing

  I would like to connect a MD3200i (with two raid controllers) to one of our Windows 2003 R2 servers without the aid of a switch.

  After most of the documentation, some things remain pretty obscure to me. I'm new to MPIO/balancing and cannot figure how to set up.

  Is it possible to connect 1 nic host to RAID 0 and another host nic to RAID 1 and then combine the bandwidth? Thus having 2Gbs instead of 1Gbs? Or is it only a redundant path sollution, happening the other controller in case of failure of the first line. How can I configure this regarding the IP addresses, subnets. And where is the configuered to load balancing. This is explained in the documentation? I can't find it. I found a few examples that include the use of a switch, but none with das sollutions.

  What I have is 4 the MD3200i UTP cables to connect to the host. 2 the high raid controller and 2 on the lower raid controller. And use that I have 4x1Gbs, resulting a connection 4Gbs to a single partition on the MD3200i of load balancing.

  Thanks for any help.

  Multiple paths and in windows 2003 load balancing is managed by the driver MPIO is installed when you install the 'host' or 'full' version install MD Storage Manager. There is no need to separately aggregated network adapters to get the aggregate bandwidth. The pilot, by default, uses repetition alternated on all ports connected to a single controller.

  Also, for a single virtual disk, all i/o through a single controller and the second controller acts as a redundant path. So, if you have 2 x 1 Gbps connections to each controller, you will have, at most, 2 Gbps for each partition. Now, each controller can have virtual disks, so the second controller may have a second partition that will also have a separate between 2 x 1 Gbps connection.

  You can set IP addresses and subnets that are similar to the way that you would with a switch as long as you can test the connection port. It would be wise for each NETWORK card on the host on a different subnet and each port on the MD3200i on the corresponding subnet. This will make it easier when you set up your iSCSI.

  You can use the configuration utility to MD in place your iSCSI sessions too

• The storage load balancing process

  We have a group of 4 members, total approximately 30 TB of space. In the past, we had a lot of volumes of 500 GB for ESX, after the installation of the ESXi5.1, we use higher volumes, about 1.5 TB. So there are a lot of changes in the storage pool. We find that the EQ is balancing of storage compared to 4 members as expected. We thought it was over two or three days agoo, but now he's balancing... then again for a couple of day all volumes are spread over 3 members, also, as expected, but he decides to charge storage it swings again... and again...  It is coming to an end sometimes?

  We have another group with 4 members and also the same amount of space, but it we do not use the 1.5 TB volumes again... here, we see that EQ is continuous storage load balancing pool.

  Im not worried yet :)), but whenever volumes are redestributing compared to members, it does not follow on some reconnects for ESX as the part of a volume can and will reside on another Member where on that time esx is not a connection to that session at that time.

  Hello René,.

  It will not be stuck in a loop.  Part of the balance to the maintenance of free space between the members.  So when several pages are written to a specific member, space balancing will create plans to move the blocks to the other members to free up space on this member.  It's an ongoing balancing act.  In addition, extended periods of heavy i/o load balancer Advanced Performance will swap pages in order to compensate for the latency between members.

  Kind regards

• Load balancing question

  Hi all

  I have a question on the load balancing between several hosts of session.

  We have 6 Guest session, I created a managed with a specifik balancing application rule "Session desktop host advanced remotely. last Friday, he started a few problems, but we have not made any changes.

  the fist session host server had 71 active users and other servers were only 30.

  How is that possible?

  Do I have to put the rule on each server load balancing?

  Hello Sander,

  You must apply the rule individually for each RDSH of load balancing. Not on the managed desktop application. In our configuration, this does not work then maybe of the same counts for you.

• Limitation of the load balancing VPN3000

  Dear all,

  How many devices can be configured for balancing the load of solutions?

  What is the upper limit?

  Can I assume that if configure US 2 devices, the throughput will be be200 MB, flow of four aircraft is 400 MB, etc.?

  Any thoughts?

  Best regards

  Engel

  No, no, the traffic is not load balanced between all hubs in the group, that the connections are. For example, when you connect with a VPN client address bundle, concentrators determine what hub is lightly loaded, your connection is then completed and supplemented by this hub. All traffic goes between your client and the hub only, like any normal connection. There is no increase in bandwidth to this connection.

  In regard to the number of devices you use, we have tested successfully with 8, but there is no theoretical limit.

• Hi ALL, did any attempt on the virtual computer NETWORK load balancing using HYPERV on UCS blades

  I try to configure the CASE server cluster by using the Unicast NLB on the virtual machine on different blades on the UCS, it works for awhile, then he abandoned packages.

  I heard that this screenplay of unicast is not supported in the UCS when she used END-host mode in the fabric interconnet...? any attempted before.

  Would it, I use the multicast mode is that something needs to be done on the FBI62020 or the LAN switch upstream. ??

  Header note I found on the implementation of UCS for mulitcast NLBL:

  Microsoft NLB can be deployed in 3 modes:

  Unicast

  Multicast

  IGMP multicast

  For series B UCS deployments, we have seen that the multicast and IGMP multicast work.

  IGMP multicast mode seems to be the more reliable deployment mode.

  To do this, the monitoring settings:

  All NLB Microsoft value "Multicast IGMP" nodes.  Important!  Check ths by logging into EACH node independently.  Do not rely on the MMC of NLB snap.

  An IGMP applicant must be present on the VLAN of NLB.  If PIM is enabled on the VIRTUAL LAN that is your interrogator.  UCS cannot function as applicant IGMP.  If an interrogator of functioning is not present, NLB IGMP mode will not work.

  You must have a static ARP entry on cheating it upstream pointing IP address Unicast NLB on the multicast MAC address NETWORK load balancing.  This need will set up, of course, on the VLAN of the NLB VIP. The key is that the routing for the NLB VLAN interface must use this ARP entry as a unicast IP ARP response may not contain a multicast mac address. (Violation of the RFC 1812)  Hosts on the NLB VLAN must also use the static entry.  You may have several entries ARP.  IOS can use a function of 'alias' of ARP. (Google it.)

  How Microsoft NLB works. -The truncated for brevity Mac addresses.

  TOPOLOGY OF NLB MS

  NETWORK VLAN 10 = subnet 10.1.1.0/24 IP load balancing

  VIP = 10.1.1.10 NETWORK LOAD BALANCING

  Arp entry static switch advanced IP 10.1.1.10 upstream to MAC 01

  NLB VIP (MAC 01, IP 10.1.1.10)

  NODE-A (AA, MAC IP:10.1.1.88)

  NŒUD-B (MAC BB, IP:10.1.1.99)

  Using the IGMP snooping and interrogator VLAN snooping table is filled with the mac NLB address and groups pointing to the appropriate L2 ports.

  MS NLB nodes will send the responses of IGMP queries.

  This snooping table could take 30 to 60 seconds to complete.

  Host on VLAN 200 (10.200.1.35) sends traffic to NETWORK VIP (10.1.1.10) load balancing

  It goes of course to VLAN 10 interface that uses the static ARP entry to resolve to address MAC 01 VIP NETWORK load balancing.

  Since it is a multicast frame destination it will be forward by the IGMP snooping table.

  The framework will arrive at ALL NLB nodes. (NŒUD-A & NŒUD-B)

  NLB nodes will use its load balancing algorithm to determine which node will manage the TCP session.

  Only one NLB node will respond to this host with TCP ACK to start the session.

  NOTES

  This works in a VMware with N1k, standard vSwtich and vDS environment. Where surveillance IGMP is not enabled, the framing for VIP MAC NETWORK load balancing will be flooded.

  NLB can only work with TCP-based services.

  As stated previously mapping an IP unicast to a multicast mac address is a violation implied by RFC 1812.

  TROUBLESHOOTING

  Make sure your interrogator is working. Just to clarify that this does not mean that it is actually at work.

  Wireshark lets check that IGMP queries are received by the NLB nodes.

  Make sure that the ARP response works as expected.  Once Wireshark again is your friend.

  Look at the paintings IGMP snooping. Validate the L2 ports appearing as expected.

  -There is no impact on the configuration, you have done service profiles.  they will continue to work as expected.  Mode selector has the FI behave more like a conventional switch.  Most notable is that Spanning tree will be activated and if you have several uplinks yew, tree covering weight will begin to block redundant paths.

  You need to review your topology and what impact tree covering weight.  Generally, we at the switch port upstream defined as "edge master", you want to delete this line.

• Nexus 1000v, UCS, and Microsoft NETWORK load balancing

  Hi all

  I have a client that implements a new Exchange 2010 environment. They have an obligation to configure load balancing for Client Access servers. The environment consists of VMware vShpere running on top of Cisco UCS blades with the Nexus 1000v dvSwitch.

  Everything I've read so far indicates that I must do the following:

  1 configure MS in Multicast mode load balancing (by selecting the IGMP protocol option).

  2. create a static ARP entry for the address of virtual cluster on the router for the subnet of the server.

  3. (maybe) configure a static MAC table entry on the router for the subnet of the server.

  3. (maybe) to disable the IGMP snooping on the VLAN appropriate in the Nexus 1000v.

  My questions are:

  1. any person running successfully a similar configuration?

  2 are there missing steps in the list above, or I shouldn't do?

  3. If I am disabling the snooping IGMP on the Nexus 1000v should I also disable it on the fabric of UCS interconnections and router?

  Thanks a lot for your time,.

  Aaron

  Aaron,

  The steps above you are correct, you need steps 1-4 to operate correctly.  Normally people will create a VLAN separate to their interfaces NLB/subnet, to prevent floods mcast uncessisary frameworks within the network.

  To answer your questions

  (1) I saw multiple clients run this configuration

  (2) the steps you are correct

  (3) you can't toggle the on UCS IGMP snooping.  It is enabled by default and not a configurable option.  There is no need to change anything within the UCS regarding MS NLB with the above procedure.  FYI - the ability to disable/enable the snooping IGMP on UCS is scheduled for a next version 2.1.

  
  
  This is the correct method untill the time we have the option of configuring static multicast mac entries on
  
  the Nexus 1000v.  If this is a feature you'd like, please open a TAC case and request for bug CSCtb93725 to be linked to your SR.
  
  This will give more "push" to our develpment team to prioritize this request.
  Hopefully some other customers can share their experience.

• Cisco RV016 failover & load balance Multi WAN question

  Hello

  I think the RV016 is the camera to buy for our small building, but I'm a bit confused in the manual if my scheduled configuration is possible, so if you could confirm if this is possible I would appreciate it.

  We have a leased line as our main connection (lets call him WAN1). If this connection is not available, I don't want to load balance to any other network WAN.

  We have 2 netgear 4G devices identical (we'll call WAN 2 and 3 WAN). If the leased line is not available, I would like to then load balance these two WAN connections.

  Then I have a final connection, WAN4 as a slow adsl line. I don't know right now if I want to load balance this WAN1 or just have it as a backup to WAN2 and WAN3 failure (WAN2 and WAN3 have a 20 GB data limit each on their monthly allowance of the contract, if the leased line is down for more than a couple of days, what is unfortunately already happened) (then we reached this limit and then there is charged with extremely expensive data or just use the only ADSL)

  In any case, it's normal, I want to balance the load. I want to only load balance WAN3 and WAN2 WAN1 fails.

  Anyone know if this is possible? If not, is there any other similar device which would be appropriate?

  Thank you

  Ben

  Hi Bencarroll01,

  With RV016 you can get what you need.

  RV016 supports up to 7 WAN connection, and there are two mode of operation

  • Swing smart (Auto Mode): This option allows you to balance traffic between all interfaces increase the available bandwidth. The router balance traffic between the weighted alternating interfaces.
  • Group of IP (by users): Select this option for trafficking group on each WAN interface by levels of priority or classes of service (CoS). With this feature, you can ensure the bandwidth and a more high priority for specified services and users. All traffic that is not added to the IP group uses Intelligent balancing mode. To specify the services and users, click modify for the WAN interface and then add the entries of binding protocol for each service, IP address or IP address range.

  For our case, we must have RV016 configured with IP Group(By User), so in this case, we can configure binding protocol that we can specify and force all traffic from any IP address of the local network outside through WAN1. and any other WAN connection they always towards the TOP but not the traffic passing through them

  Now if WAN1 is down, immediately the rule to redirect traffic WAN 1 will be disabled and all traffic will pass through the rest of the WAN connection

  After that if the WAN1 is once again the binding protocol rule will be active again and again all the traffic will be done by WAN 1

  Please let me know if you have any other questions

• OSPF load balancing

  Hello

  Does anyone know how to deploy load balancing in OSPF area 0?

  Any suggestion for documentation would be apreciated.

  Thanks in advance for your help

  Hello

  OSPF is only the equal cost load balancing, so you must have two channels with equal to the destination charges.

  This command must also be set to more than one:

  maximum-paths

  under router ospf configuration.

  I think you also need ip cef enabled.
