Connection Load Balancing question

Hi All,
this is from oracle net8 Administrator's Guide (between double quotes):
"Connection load balancing improves connection performance by balancing the number of active connections among multiple dispatchers. In an Oracle Parallel Server environment, connection load balancing also has the capability to balance the number of active connections among multiple instances. "
My question is, from that statement above, does it mean that the connection load balancing can only be useful on a OPS with MTS instances?
and second is , does it make sense (or can it be done) to implement it on single instance of MTS?
TIA,
Andi

Hi Andi,
CLB is only used in cluster configuration! In single node instance there is no advantage for ovbious reason of putting one more layer.
you are right...use only with OPS and preferably with MTS.
Best,
G

Run-time connection load balancing

Hello!
I'm using jdbc thin client (10g) and I'm trying to improve connection pool management. I would like to enable run-time connection load balancing. Is this option
available with Fast Connection failover?
Basically when a a client requests a connection from the connection cache by calling the getConnection method on the DataSource object, I want that the connection selected
is the connection that belongs to the best instance from the connection cache. The client receives the connection that would process the work request with the
best response time.
With run-time connection load balancing ebabled what's happen when new connection is requested? The same algorithm?
Other question:
Is it possible create a manually process to distribute new connections? Having the following connection string:
url="jdbc:oracle:thin:@
(DESCRIPTION=
(ADDRESS=(protocol=tcp)(host=192.168.12.17)(port=1521))
(ADDRESS=(protocol=tcp)(host=192.168.12.18)(port=1521))
(load_balance=on)
(connect_data=(service_name=EHR)))"
In a specific moment I want that new connections only will be created in a specific instance... How can I do this? P.e.
Connection POOL has 10 connections (5 in each instance). All sessions are active and a new session needs to be created. At this moment I want to decide wich instance
is the best to attend the request...
Thanks a lot
Best Regards

Hi, there are several questions here. So, let me try to answer some, and I could address more if you have further questions. I am also presuming you are using JDBC driver's
colocated Implicit connection cache.
1) Yes, you need to enable FCF on the pool to leverage RCLB. Note, there are
no specific knobs for RCLB on the client side, only the RAC / DB side which requires
LBA to be enabled (this is documented in the RAC clusterware admin guide)
2) When LBA is enabled on RAC/DB, RAC starts posting FaN events to the pool.
This enables the pool to pick the best connection to an instance with the best
service response time or throughput -- depending on how LBA was enabled.
3) When new connections are created, the pool relies on the DB listener to place/create
the connections on the appropriate RAC instance -- this depends on the LBA goal you
set, and is required to be set to "short"
4) The pool currently does not have the ability to create a conn to a named instance.
What's the requirement or use case for this? If we understand this better, perhaps
we could address this. How do "you" decide which is the best instance to connect?

SO Load Balancing Question

Hi all,
I have a service object (SO1) which has been set to Load Balancing.
This service object has an attribute which serves as a number allocator
(NA1).
This NA1 provides a unique number across the whole application for each of
the record that require to store into DB.
The problem is, will the NA1 get replicated if the SO1 is replicated?
If yes, will NA1 crash?

Hi Serge,
Could you prefix it with the PID of the load balanced process ?No I can't. At least not at the moment.
When a service object is replicated, it is automatically replicated into adifferent partition...
Thanks.
An advice, make the NA1 shared. So if you get to do multithreaded accessto
it, you won't screw up things.I am thinking it may be better off to create it as a service object on it's
own.
How is the number returned by the NA1 generated ?It gets generated by Forte's code.
... Try to make it so that the
load balanced partitions don't need to access the database more than onein
5 min. to get a new Seed Key. This would not need to PID.Thanks for your advise.
Regards
Martin Chan

Your right, they can generate the same number. How much control do you have
over the ID being generated? Could you prefix it with the PID of the load
balanced process ?
Just a note: When a service object is replicated, it is automatically
replicated into a different partition, possibly on the same machine or on a
different one.
An advice, make the NA1 shared. So if you get to do multithreaded access to
it, you won't screw up things.
How is the number returned by the NA1 generated ? If NA1 is using a stored
procedure, or something like:
Start TRX
read number
newnumber = number+5000
write back newnumber
End Trx
Something like will be very safe. The Database Index Table is taking care
of the critical section. Then you can be sure that each replicate can be
independent (not hit into each other) for 5000 iterations. Depending on the
frequency, you may want to up this number or lower this number. Too high it
would make the key very high very soon with wholes in the sequence. Too low
and you would have hit between the replicates. Try to make it so that the
load balanced partitions don't need to access the database more than one in
5 min. to get a new Seed Key. This would not need to PID.

Hi Serge,
The number return by the NA1 is used as a primary key for each of therecord
that stores in the DB.
The Number Allocator NA1 is required to access to DB to update an ID table
which carry the next available sequence number. NA1 will only update this
table for every 5000 records.
For example, the initial value of the sequence is: 1
The next update will change the value to 5001, next will be 10001 and soon.
>
The properties of this NA1 class at runtime
Shared - Disallowed
Distributed - Disallowed
Transactional - Is Default
Monitored - Disallowed
Unfortunately, this attribute is not a handle but is instantiated by theSO1
itself.
I have been thinking, if SO1 is replicated within the same partition, and
each replicate will carry its own NA1. NA1 and the replicate of NA1 may
return a same number if their initial values of the sequence are the same.
Correct?

Subject: Re: (forte-users) SO Load Balancing Question
Let's see if I understand right.
You have a service object that keep a handle to an object that either keep
state information, or that generate state information. Now the thing to
figure out is which is it. Let's assume that NA1 is a number generator,
that does not need to be synchronized or that doesn't need to access any
external resource. It would still work, depending on the algorythm you are
using.
Will they share the same NA1? It depends on the nature of NA1, but for sure
NA1 would have to be an anchored object. An if multiple partitions would
share the same object "only" for key generation, you would bring down your
performance on key generation or key update (by adding one inter-process
call).
In short:
1. Many scenarios can happen, you need to be clearer on your description.
2. If you are sharing an object by load balanced partitions, this greatly
reduce the gain of load balancing the partition.
3. If NA1 is keeping state, any access to it would need to be controlled
"shared".
Have fun now...

Howto - connection load balancing

Hello
I have a 11.1.0.7 clustered oracle db with two nodes. Using the oci access through the ojdbc14.jar for oracle 9.2.0.1 I programmed a datasource like this:
public class DataSource_9i_oci
extends OracleOCIConnectionPool
public DataSource_9i_oci() throws SQLException
super();
setUser(RACBehaviourTest.UNAME);
setPassword(RACBehaviourTest.PSWD);
setURL("jdbc:oracle:oci:@tnsname");
Properties poolConfig = new java.util.Properties( );
poolConfig.put (OracleOCIConnectionPool.CONNPOOL_MIN_LIMIT, "1");
poolConfig.put (OracleOCIConnectionPool.CONNPOOL_MAX_LIMIT, "100");
poolConfig.put (OracleOCIConnectionPool.CONNPOOL_INCREMENT, "2");
setPoolConfig(poolConfig);
My TNSNAMES.ORA contains the name
tnsname=
(description=
(load_balance=on)
(failover=on)
(address_list=
(address=(protocol=tcp)(host=xxx.xx.xx.xxx)(port=1521))
(address=(protocol=tcp)(host=xxx.xx.xx.xxx)(port=1521)))
(connect_data=
(service_name=service.name)
(failover_mode =
(type = select)
(method = basic))))
Then I spawned a group of threads each issuing a select statement and holding after that, until a central thread collects session statisticss from gv$session about the opened sessions in each instance for my user, and unblocks the working threads only after that.
This test is aimed at evaluating the load balancing capabilities of the oci vs thin drivers in different versions. The code above is the data source being used with the 9.2.0.1 oci driver.
Then I have another DataSource to be used in the same test and the ojdbc6.jar thin driver for 11.1.0.7. It is programmed like this:
public class DataSource_11g_thin
extends OracleDataSource
public DataSource_11g_thin(boolean enableFCF) throws SQLException
super();
String url = "jdbc:oracle:thin:@(DESCRIPTION=(LOAD_BALANCE=on) " +
"(ADDRESS=(PROTOCOL=TCP)(HOST=xxx.xx.xx.xxx) (PORT=1521)) " +
"(ADDRESS=(PROTOCOL=TCP)(HOST=xxx.xx.xx.xxx) (PORT=1521)) " +
"(CONNECT_DATA=(SERVICE_NAME=service.name)))";
setURL(url);
setUser(RACBehaviourTest.UNAME);
setPassword(RACBehaviourTest.PSWD);
setImplicitCachingEnabled(true);
Properties props = new Properties();
props.setProperty("InitialLimit", "500");
props.setProperty("MaxLimit", "500");
props.setProperty("ValidateConnection", "true");
setConnectionCacheProperties(props);
This test is using connection load balancing without leveraging the FAN infrastructure.
So, with this setup and creating 100 threads, what my tests show is that there's no load balancing in the 9i oci driver, all the 100 sessions are being opened in the same instance. The 11g thin driver however, distributes the opened sessions between the two nodes, even if in an unbalanced way (70-30).
Is there any way to activate load balancing in the oci driver ? Am I missing something ?
Thank you in advance.

CSS load balancing questions

I hope that someone can help with 2 simple (i think) CSS questions.
1. When configured properly for load balancing, should the CSS round-robin between servers or will it continue to use only one server until triggered by some event or parameter?
2. If 1 of 2 load balanced servers fails, how does load balancing proceed? Will it continue to try to load balance between the servers or will it give up on the failed server unitil some event or timeout occurs?
Thanks in advance,
Eliot

Hi Eliot,
The CSS can be configured to perform load balancing in a variety of different ways. Least connections, round robin, ACA etc. Each new connection through the CSS will be round robined over each of the servers in your server group.
If a server fails then the CSS will know it has failed through the use of keepalives (based on TCP connection, ICMP etc) and no longer send requests through to that server. Traffic associated with a previous connection to the failed server will be sent to on of the surviving servers. It is then up to the behavior of the application as to if the user experiences any disruption.
Hope this helps
Brett

Clustering problems and load balancing question

          I am using Weblogic 6.1. My Windows NT environment consists of 10 web client-simulator
          machines, 2 App. Server machines and one database server machine. I have defined
          one cluster on each app. server. Each cluster is running 3 Weblogic instances, or
          so it should be when I fix my problems!
          My questions/problems are the following:
          1. Can I use a software dispatcher to perform workload balancing between the 2 weblogic
          clusters? That is, the client-simulator machines send the requests to the software
          dispatcher which performs workload balancing between the 2 Weblogic clusters. The
          clusters perform round-robin amongst all instances. Note that the documentation only
          talks about Hardware Balancing.
          2. I am having problems with my multicast IP addresses. For instance, on one App.
          Server machine, I am using the multicast IP address: 239.0.0.1 for MyCluster. When
          I start the Admin Server, I get a JDBC error: "... multicast socket error: Request
          Time Out". I have used the utils.MulticastTest utility which shows the packets not
          being received:
          I (S1) sent message num 1
          I (S1) sent message num 2
          I (S1) sent message num 3
          I (S1) sent message num 4
          What am I doing wrong?
          3. Re. the cluster configuration:
          NOTE: I have executed my workload using 2 independent App. Server machines with a
          software dispatcher - no clustering. Each App. Server used a jdbc connection pool
          of 84 database connections. The db connections happened to become my bottleneck.
          When I tried to increase the number of connections in the jdbc pool, throughput decreased
          dramatically. Thus, I decided to add a cluster of Weblogic instances to each one
          of my 8 x 900Mhz machines in order to scale up. Unfortunatly, adding clusters have
          not been that simple a task - probably because I am totally new to the Web Application
          Server world!
          Here is what I've got so far:
          I have obtained 3 static IP addresses for the 3 instances of Weblogic instances that
          I wish to run within the cluster. All servers in the cluster use port number 80.
          There is a corresponding DNS entry for each IP address. My base assumption is that
          one of these instances will double up as the Administration Server... Is it true,
          or do I need to define a separate Admin server if I wish to run 3 Weblogic instances
          (each with a connection pool of 84 database connections for a total of 252 database
          connections)?
          Do I need to re-deploy my applications for the cluster? And if so, would this explain
          why I am having problem starting my Admin Server?
          I think this is it for now. Any help will be greatly appreciated!
          Thanks in advance,
          Guylaine.

          We also support software load balancers (for e.g. resonate)
          The software dispatcher should be intelligent enough to decode the
          cookie and route the request to the appropriate servers. This is
          necessary to maintain sticky load balancing.

          You should run the above utility from multiple windows and see if each
          of them being recognized or not.
          i.e. java utils.MulticastTest -N S1 -A 239.0.0.1

          BEA recommends to use Admin server for administrative tasks only
          like configuring new deployments, jdbc conn pools, adding users etc..
          It's not a good idea to have admin server part of cluster.

Hypothetical RAC load balancing question

Im trying to get a better understanding of RAC. Suppose I have the following tnsnames entry on Client1:
DEV =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = dev010.net)(PORT = 1795))
(ADDRESS = (PROTOCOL = TCP)(HOST = dev020.net)(PORT = 1795))
(LOAD_BALANCE = yes)
(FAILOVER = yes)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = dev1)
(failover_mode=(type=select)(method=basic))
dev010.net and dev020.net are two nodes that I am trying to balance the connection from Client1 to.
dev010.net and dev020.net have the following listener.ora configurations respectively:
LISTENER_DEV1 =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = dev010.net)(PORT
= 1795))
SID_LIST_LISTENER_DEV1 =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /oracle/ora92)
(PROGRAM = extproc)
(SID_DESC =
(ORACLE_HOME = /oracle/ora92)
(SID_NAME = dev1)
LISTENER_DEV2 =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = dev020.net)(PORT
= 1795))
SID_LIST_LISTENER_DEV2 =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /oracle/ora92)
(PROGRAM = extproc)
(SID_DESC =
(ORACLE_HOME = /oracle/ora92)
(SID_NAME = dev2)
Question: since 'lsnrctl services' shows LISTENER_DEV1 and LISTENER_DEV2 are registered with services dev1 and dev2 respectively, how do I load balance Client1's connection between the two nodes if its service name is set to dev1?
Can you set up RAC with some sort of master listener?
Im new to RAC, so any help would be appreciated.

Try this:
LISTENER =
(ADDRESS_LIST =
        (ADDRESS =
          (PROTOCOL = IPC)
          (KEY = DB1.WORLD)
        (ADDRESS=
          (PROTOCOL = IPC)
          (KEY = DB1)
        (ADDRESS =
          (COMMUNITY = MYRAC.WORLD)
          (PROTOCOL = TCP)
          (HOST = )
          (PORT = 1521)
SID_LIST_LISTENER =
(SID_LIST =
    (SID_DESC =
      (SID_NAME = DB101)
      (ORACLE_HOME = /oracle/Ora92)
    (SID_DESC =
      (SID_NAME = DB102)
      (ORACLE_HOME = /oracle/Ora92)
)

Exchange 2013 Load Balancing Question

Hey Everyone,
I have recently started building up my companies Exchange 2013 environment and ran into some questions that I can't seem to find clear answers for on Google.
First, a little bit about my set up:
2 CAS Servers
2 Mailbox Servers
Citrix NetScaler load balancing the external URL (Controlling all incoming ports 25, 80, 443, 587, 993, and 995) to both of my CAS servers
This is not doing SSL offloading, it's just forwarding encrypted traffic to the CAS servers
I have configured a DAG between the 2 mailbox servers and am able to actively move the database my user account is on between the 2 copies with outlook disconnecting / reconnecting in about 10 - 15 seconds of moving it.
My questions started when I saw what Outlook was filling in for the "Server" field once autodiscover set it up. I found this very strange server name in it: *** Email address is removed for privacy ***
Once I read up on it, I think i understand what it does. If i understand correctly, this weird URL is sort of like an old CAS array from Exchange 2010. When I started testing the failover is when I started running into issues.
When I shut down one of my mailbox servers, my outlook will lose connection and it won't come back. The mailbox database that my user account is on successfully failed over to the other DAG copy but outlook never correctly connects. I
believe this issue has something to do with the new CAS functions of Exchange 2013 since DAG works fine.
If I look at my "Connection Status" in Outlook, I see that there are several connections open. All of them have a Proxy server address of "exchange.domain.com" and out of the 3 that show up there, they are all pointed to
the weird URL mentioned above.
Whew, long post but let me summarize my questions below:
1) If exchange is configured to be fully redundant, why does my outlook disconnect when I shut down one of the servers?
2) What is the weird URL pointing to that I mentioned above that is showing in outlook?
3) How can I get outlook to correctly not lose it's connection when any 1 of the servers goes down?
Thanks,
Zac

Hi,
According to your description, it seems that the load balancer did not configure successfully.
I recommend you refer to the following article to configure the load balancer for Exchange 2013 :

N2000 weighted load balance question

Hi --
I have a question about how to use a weighted load balancing configuration to support a failover condition.
My goal is to have an active and a standby configuration. This is not a web application, so it doesn't follow the same type of rules. In particular, I have a situation where there are multiple clients establishing long-term connections to a server. If the server goes down, I would like the LB to close the connections and when the clients try to reconnect it will route to the standby system.
My question is: If I configure the 'weighting' for the active server to be 1 and for the standby server to be 0, will it always result in incoming connections being routed to the active server (and never the standby server)? If the active server is down, will it still route to the standby even though the weight is zero?
Any thoughts/ideas/suggestions are greatly appreciated.

Hi --
I have a question about how to use a weighted load balancing configuration to support a failover condition.
My goal is to have an active and a standby configuration. This is not a web application, so it doesn't follow the same type of rules. In particular, I have a situation where there are multiple clients establishing long-term connections to a server. If the server goes down, I would like the LB to close the connections and when the clients try to reconnect it will route to the standby system.
My question is: If I configure the 'weighting' for the active server to be 1 and for the standby server to be 0, will it always result in incoming connections being routed to the active server (and never the standby server)? If the active server is down, will it still route to the standby even though the weight is zero?
Any thoughts/ideas/suggestions are greatly appreciated.

Load Balancing question

My company is in the process of building a small scale network architecture strictly for testing purposes. We have a DMZ area that contains 2 load balancers and 1 web server. The web server is a SunFire 280 and has two gig e nics. They want to cable one nic to one load balancer and one nic to the other. Since this is only one box we have to put the nics on separate subnets. The question is, can I configure the load balancers in a failover situation of an active active situation with one load balancer on one vlan and another load balancer on a separate vlan.

I did not able to understand why you want to give ip to two NICs from different subnets.
There is NO any requirement, like that. If you have your own requirement can you explain me that?

Cisco CSS 11503 Arrowpoint/Load Balance question

I am troubleshooting an issue with my 11503. I am running version 07.40.0.04. I have it configured as follows:
content upcadtoa-rule
    add service cadtoa-wls1-e0
    add service cadtoa-wls1-e1
    add service cadtoa-wls2-e0
    add service cadtoa-wls2-e1
    add service cadtoa-wls3-e0
    add service cadtoa-wls3-e1
    add service cadtoa-wls4-e0
    add service cadtoa-wls4-e1
    add service cadtoa-wls5-e0
    add service cadtoa-wls5-e1
    add service cadtoa-wls6-e0
    add service cadtoa-wls6-e1
    arrowpoint-cookie expiration 00:00:15:00
    protocol tcp
    port 8001
    advanced-balance arrowpoint-cookie
    redundant-index 2
    vip address 172.30.194.195 range 2
    arrowpoint-cookie name TOA
    active
However, the load-balancing across the servers does not seem to be doing much balancing. One of those servers is getting hit with 5 times as much traffic as another and another server is lucky to get a connection at all. With the cookie expiration set, one would think that this would all balance out over time.
I just came across this information from Cisco and I am wondering if it is relevant:
If you configure a balance or advanced-balance method on a content rule that requires the TCP protocol for Layer 5 (L5) spoofing, you should configure a default URL string, such as url "/*". The addition of the URL string forces the content rule to become an L5 rule and ensures L5 load balancing or stickiness. If you do not configure a default URL string, unexpected results can occur.
In the following configuration example, if you configure a Layer 3 (L3) content rule with an L5 balance method, the CSS performs L5 load balancing, but will reject UDP packets.
content testing
vip address 192.168.128.131
add service s1
balance url
active
The balance url method is an L5 load-balancing method in which the CSS must spoof the connection and examine the HTTP GET content request to perform load balancing. The CSS rejects the UDP packet sent to this rule because a UDP connection cannot be L5. Though the CSS allows this rule configuration, its expected behavior would be more clear if you promote the rule to L5 by configuring the url "/*" command.
In the next example, if you configure an L3 content rule with an L5 advanced-balance method, L5 stickiness will not work as expected.
content testing
vip address 192.168.128.131
add service s1
advanced-balance arrowpoint-cookie
active
The advanced-balance arrowpoint-cookie method causes the CSS to spoof the connection, however, the CSS still marks it as an L3 rule. Thus, the CSS does not insert the generated cookie and the rule defaults to L3 stickiness (sticky-srcip). You must configure a URL like url "/*" to promote this rule to L5, ensuring that L5 stickiness works as expected.
Thanks in advance for any help you can give. The thing is not down, it is just balancing strangely causing application performance issues.
James

Hey James,
You will need to suspend the content rule in order to add the url statement. This will cause a quick downtime until the content rule is activated again. I have shown below the commands to add the statement. Perhaps you can create your commands in a Notepad file, then paste them all in so they execute quickly to minimize your downtime:
content MY-SITE
    vip address 10.201.130.140
    port 80
    protocol tcp
    add service MY-SERVER
    active
CSS11503# config t
CSS11503(config)# owner TEST
CSS11503(config-owner[TEST])# content MY-SITE
CSS11503(config-owner-content[TEST-MY-SITE])# url "/*"
%% Attribute may not be modified on active rule
CSS11503(config-owner-content[TEST-MY-SITE])# suspend
CSS11503(config-owner-content[TEST-MY-SITE])# url "/*"
CSS11503(config-owner-content[TEST-MY-SITE])# active
CSS11503(config-owner-content[TEST-MY-SITE])# exit
CSS11503(config-owner[TEST])# exit
CSS11503(config)# exit
CSS11503# show run
content MY-SITE
    vip address 10.201.130.140
    add service MY-SERVER
    port 80
    protocol tcp
   url "/*"       <--------
    active
Hope this helps,
Sean

Office Web App Load balancing Question

I am going to install office web app in load balanced farm behing f5. There are few questions i want to ask:
Do i first put servers in load balancer and start installing office web app or after installation of office web app in one server put that in load balancer and add another one or put both in load balancer and start installing.
While i tried without putting servers in load balancer with offload ssl parameter , when i tried to join second server in the farm it gave me error destination unreachable. Is it because with offload ssl parameter it is looking for load balancer or something
else? I checked port 809 from the servers and also verified the user was local admin in both machines.
Any insight will be helpful.
Adit

JMS load-balancing question

Hello,
When performing settings on JMS connection factory, one can set (check the "Load Balancing Enabled" option in the Configuration tab, Load Balance sub tab).
In the help documentation, we can read:
Specifies whether non-anonymous producers created through a connection factory are load balanced within a distributed destination on a per-call basis.
*If enabled, the associated message producers are load balanced on every send() or publish() .+
I have performed some tests and I don't see the expected behaviour that is to say load-balancing for each send or publish call.
So first what does mean "non-anonymous producers" ? Does that mean that we have to create JMS connection with username/password arguments ? If yes, I have used the same credentials than the ones used for the admin console and again I don't see load-balancing on physical queues belonging to one distributed queue !
Could you give, please, me advice on how to get the load-balancing working per send or publish call ?
Best Regards.

LACP/Load Balancing Question

This past weekend we replaced our Catalyst 4506 switches with a combination of Catalyst 4500-X switches (provides fiber and 10 GB connections to our closet switches and our UCS) and 2960-X switches (all other servers and printers are connected here). Our backup server has two NICs teamed into a NIC Team (port 35 and 36 on the 2960-X switch). The NIC team was set to the following:
Team Type Selection: 802.3ad Dynamic with Fault Tolerance
Transmit Load Balancing: Dest IP Address
Since we switched to the new switches we are seeing a high number of discards from our backup server on one of the ports in the NIC team. I verified the port-channel configuration on the switches and set the "port-channel load-balance" to src-dst-ip. When running the test etherchannel command from one of my servers to the backup server it responds that it would choose port 36. When I run a backup from this same source server to my backup server it chooses port 35 for everything. I would expect this if the data is coming from the same source ip to the backup server. To confirm this I added another test job from a different source IP. It still only chooses port 35.
If I "show lacp 3 counters" here's what I see:
             LACPDUs         Marker      Marker Response    LACPDUs
Port       Sent   Recv     Sent   Recv     Sent   Recv      Pkts Err
Channel group: 3
Gi2/0/35    14616 12368    0      0        0      0         0
Gi2/0/36    14628 12368    0      0        0      0         0
From this it appears the switch is pretty evenly distributing data across both channels. Am I correct? If that is true then is it a fair assumption that something on the backup server is rejecting the data on port 36 and thus causing the discards?
Just need an opinion on what might be going on to help convince people as to where the problem lies.
Thanks.

RV042 - Load Balancing question

Hi, I have the RV042 (firmware 1.3.13.02-tm) in Load Balancing mode. When I do a speedtest, the result is the total bandwidth available on my 2 connections, i.e. 8-9,000 Kbit/Sec (each line is approx 4,500 Kbit/Sec). When I stream from Netflix, the bandwidth throughput is about 4-4,5000 Kbit/Sec. Should not the RV042 stream Netflix as the combined speed between WAN 1 and 2, i.e. at 8-9,000?

Load balance permits more available bandwidth. It may effective double the speed because the requests have more pipe available to utilize but not because it increases the over all speed of your connection. If your connections are 5 mbit they remain 5 mbit.
