Multiple roles load balancing on Ms Exchange 2010

Dear list member !
Currently. I installed Ms Exchange SP3 Multiple roles on a single server. I have been planning deploy add a member exchange 2010 SP3 for redundancy DAG but these are
people also IT operation told to me so install CAS, HUB, MB Roles will Load balancing CAS, DAG based on TWO Server "Ex 2010 SP3:". Following Microsoft document, then almost do not that.<o:p></o:p>
Please feedback to able or unable
very appreciate

Hi,
To load balance CAS servers, you need to use the Windows Network Load Balancing or the Hardware Load Balancing. For more details about this, you can refer to the following article.
Understanding Load Balancing in Exchange 2010
http://technet.microsoft.com/en-gb/library/ff625247(v=exchg.141).aspx#options
If you want to deploy DAG in your environment and you also want to load balance your CAS servers, it is recommended to install Mailbox server role and CAS role on different servers. Because DAG members utilize Windows Failover Clustering, which can’t co-exist
with WNLB. Of course, you can choose to use HLB to load balance CAS servers.

MULTIPLE LISTENER의 LOAD BALANCING 및 2개의 NETWORK CARD 사용 시 SETUP
=====================================================================
Oracle V7.3의 SQL*Net 2.3의 새로운 기능으로 여러 개의 Listener를 띄우면서
상호 Load Balancing을 유지하는 기능을 소개하고자 한다.
Load Balancing 기능을 이용하여 각각의 Listener와 Oracle Instance 간의
Overloading을 줄일 수 있다.

ISE 1.2 - Multiple NICs/Load Balancing for DHCP Probe

Hello guys
Just prepping an ISE 1.2 patch 8 setup in our organization. I am going for the virtual appliances with multiple NICs. It will be a distributed deployment with 4 x PSNs behind a load balancer and there is no requirement for wireless or guest user at the moment. I've got 2 points I will like to get some guidance on:
Our DC has a dedicated mgmt network and I plan to IP the gig0 interface of the PANs, MNTs and PSNs from this subnet. All device admin, clustering, config replication, etc will be over this interface. However, RADIUS/probe/other user traffic to the ISE PSNs will be over the gig1 interface which will be addressed from another L3 network. Is this a supported configuration in ISE?
I intend to use the DHCP probe as part of device profiling and will ideally like to have just an additional ip helper to add to our switch SVI config. Also, it will appear that WLCs can only be configured for 2 DHCP servers for a given network so another consideration for when we bringing our WLAN in scope. We however use ACE load balancers within our DC and from what I have read, they do not support DHCP load balancing. Are there any workarounds to using the DHCP probe with multiple PSNs without having to add each node as an ip helper/DHCP server on the NADs?
Thanks in advance
Sayre

Hello Sayre-
For Question #1:
Management is restricted to GigabitEthernet 0 and that cannot be changed so you should be good there
You can configure Radius and Profiling to be enabled on other interfaces
Even though you are not using guest services yet, you can dedicate an interface just for that. As a result, you can separate guest traffic completely from your production network
Take a look at this link for more info:
http://www.cisco.com/c/en/us/td/docs/security/ise/1-2/installation_guide/ise_ig/ise_app_c-ports.html
For Question #2
If you are using a Cisco WLC and running code 7.4 and newer you don't need to mess with the IP helper configurations.
The controller can be configured to act as a collector for client profiling and interact with the DHCP thread along with the RADIUS accounting task that is running on the controller. The controller receives a copy of the DHCP request packet sent from the DHCP thread and parses the DHCP packet for two options:
–Option 12—HostName of the client
–Option 60—The Vendor Class Identifier
After this information is gathered from the DHCP_REQUEST packet, a message is formed by the controller with these option fields and is sent to the RADIUS accounting thread, which is in turn transmitted to the ISE in the form of an interim accounting message.
Both DHCP and HTTP profiling settings are located under the "Advanced" configuration tab in the WLC
On the other hand, you can also use Anycast for profiling. You can check out some of Cisco Live's sessions for more info on that. Here is one that is from a couple of years (There are more recent ones that are available as well):
http://www.alcatron.net/Cisco%20Live%202013%20Melbourne/Cisco%20Live%20Content/Security/BRKSEC-3040%20%20Advanced%20ISE%20and%20Secure%20Access%20Deployment.pdf
I hope this helps!
Thank you for rating helpful posts!

Configuring 2 css11503s for multiple service load-balancing

first here's my present config on one of my CSS11503:
!************************** CIRCUIT **************************

here are my questions:
1) how do I configure an additional vip address? e.g. I'd like to configure a vip - 19.10.28.215 to load-balance http traffic to 10.15.15.25 and 10.15.15.26?
2) I presently have a static route in my core router "ip route 10.15.15.0 255.255.255.0 19.10.28.210". (this enables the load-balanced servers to connect to Oracle servers on the Core network). do I need to configure a new route on my core router when I add the additional vip 19.10.28.215?
relevant references and/or examples will be much appreciated.
dayo

1/ configure the following :
service web1
ip address 10.15.15.25
active
service web
ip address 10.15.15.26
active
content WEB
vip address 19.10.28.215
proto tcp
port 80
add service web1
add service web2
active
2/ I would create a redundant-interface and point your static route to this redundant ip address.
you should not use vip address in static route.
VIP address should only be used when you want to reach the vip address not a when you want a direct connection to the real server.

Multiple ISP load balancing

Hi All,
I am having three ISP link at location and I want to use all of them for my outgoing Internet traffic,Can anyone help me how can I accomplish this.
Thanks
SS

What is the routing protocol used in your router?
Is all three links are connected in a single router?
Generally, if you add three default routes to three links with same AD, it does equal cost load balancing. Also if CEF is runnig, by default, it does per destination load balancing.

Multiple wan load balancer

Hi team,
I have 4 ISP connected to a router when one ISP goes down I need to manually change to another ISP
Is there any utm box which support auto load balancer

I am also looking for the solutions for this problem. You got any solution then Please share with us.

Server Load-balancing Across Two Data centers on Layer 3

Hi,
I have a customer who would like to load balance two Microsoft Exchange 2010 CAS Servers which are residing across two data centers.
Which is the best solution for this? Cisco ACE or Cisco ACE GSS or both?

I would go with source natting the clients ip addresses, so that return traffic from the servers is routed correctly.
It saves you the trouble with maintaining PBR as well.
Source NAT can be done on the ACE, by applying the configuration to either the load balancing policy, or adding the configuration to the class-map entries in the multi-match policy.
Cheers,
Søren

Configure Barracuda Load Balancer with Exchange 2010

I have following scenario:
1 x DB
1 x Exchange multi role server on VLAN1 on site 1
1 x Exchange multi role Server on VLAN2 on site 2
1 x cas array on site 1
1 x cas array on site 2
1 x Barracuda at site 1.
How barracuda will load balance my 2 exchange servers located on different subnets and sites? Do i need to make them SINGLE SITE? and make them part of single array or i can do it without bringing them into single site. Barracuda can access both exchange servers.
I cannot move servers, all i have to do is in the same scenario and that is to load balance CAS services.
Hasan

If your network supports(i.e. Bandwidth between Vlan1 and Vlan2) and if it is single ADsite you can. You have to add both Vlan1 server and Vlan2 server to the load balancer.
Enable DAC on both servers http://technet.microsoft.com/en-us/library/dd979790(v=exchg.150).aspx
Cconfigure alternatewitness on DAG properties. http://technet.microsoft.com/en-us/library/dd297934(v=exchg.150).aspx
One server with all roles in Vlan1 IP 192.168.1.101
One server with all roles in Vlan2 IP 192.168.2.101
Assume you configured 192.168.1.100 as Barracuda VIP and pointed the names to this IP.
If your Vlan1 network goes down your Exchange will go offline till you point the CAS Array FQDN to the IP of the Vlan2 server in Vlan2 DNS server. (i.e point CAS array FQDN to 192.168.2.101 as per above example)
If you are not sure about the configuration on Barracuda I suggest you take help from Barracuda support to configure as per the above scenario.
If you want to reduce the traffic between Vlans you can switchoff shadow redundancy. Please read about
shadow redundancy before switching off
Set-TransportConfig -ShadowRedundancyEnabled $false
Thanks, MAS
Please mark as helpful if you find my comment helpful or as an answer if it does answer your question. That will encourage me - and others - to take time out to help you.
I got you. Now if i make both Vlans server part of single array and that array FQDN IP will obviously be one of VLANs IP, so if that VLAN goes down then i need to change the IP of CAS array FQDN from local DNS (Pick one IP from another VLAN) and also on
Barracuda... right?
Also correct me that VLAN IP on Barracuda will be the IP of CAS Array FQDN right?

Recommended configuration for load balanced Portal with load balancer, multiple gateways and multiple servers.

Does anyone have a recommended network, hardware and software configuration guide for a Portal installation running with multiple gateways load balanced (ie one URL) that talk to multiple servers?

David,
We've used Resonate (software) to load balance the gateways. It allows
you to group all the gateways under 1 virtual URL and load balance the
incoming connections over each gateway depending on the rules that you
define in Resonate. Look in the SUN portal whitepapers there is one that
talks about it specifically.
As far as load balancing the calls to the portals, the gateways will
automatically load balance across all the portals that they know about
using a simple round-robin rotation. You may be able to use Resonate in
front of the portals but you may need to activate persistance within
Resonate to ensure that the user always ends up on the portal that he
established his initial connection on (if you want that), check with Sun
on this one.

Staging the NLB cluster Static port change of Exchange 2010 CAS or do it all in one day ?

Folks,
Here is the server deployment in my AD domain:
Email flow and Outlook client connection go through the NLB cluster VIP email.domain.com.au which is served by the following server:
PRODHT-CAS01 (HT-CAS Server Windows NLB node 1)
PRODHT-CAS02 (HT-CAS Server Windows NLB node 2)
Public Folder access through Outlook client goes through the following servers:
PRODMBX01 (Stand-alone Mailbox Server 1) no DAG
PRODMBX02 (Stand-alone Mailbox Server 2) no DAG
Can I make the changes first on the first stack of Exchange Server set as below first:
PRODHT-CAS01 (HT-CAS Server NLB node 1)
PRODMBX01 (Stand-alone Mailbox Server 1) no DAG
in order to test the Outlook email & Public Folder connectivity in the first week and then followed by the rest of the server set:
PRODHT-CAS02 (HT-CAS Server NLB node 2)
PRODMBX02 (Stand-alone Mailbox Server 2) no DAG
would that cause the NLB or user email access problem?
Do I have to make the changes all in one day for those four servers followed by the reboot?
Reason of changing: The hardware load balancer (Riverbed) requires to have static RPC port to work properly.
This is the article to change the Static port in my NLB cluster Exchange HT-CAS server role on Exchange Server 2010 SP2: http://social.technet.microsoft.com/wiki/contents/articles/864.configure-static-rpc-ports-on-an-exchange-2010-client-access-server.aspx
Thanks in advance.
/* Server Support Specialist */

All the servers behind the load balancer must be the same.
You can change the stand alone MBX server's RCA port as that traffic is not load balanced.
Changing Exchange is straight forward, just be careful to enter the registry keys correctly and then check AB and RCA is listening on the new static ports after you restart the services.

Rhoderick,
Many thanks for the suggestion. My goal here is to minimize any impact / email service downtime to the user while configuring the static ports.
1. Do I have to dissolve the Windows NLB cluster after the static port configuration on both HT-CAS servers or can I still keep the NLB cluster?
2. "All the servers behind the load balancer must be the same." Do you mean do I have to do the static RPC port the same day for all server set ?

Configuring NLB Exchange 2010

Our environment only has one CAS/HT server. No NLB Array was configured. I wanted to verify the steps on getting this properly configured:
Build and patch NEW server – server 2010-2.
Install Pre – Requests.
Install Exchange CAS/HUB server roles.
Rename current CAS/HT server from 2010 to 2010-1 and change IP.
Install NLB.
Create NLB Cluster – name cluster 2010 keep same IP of current CAS/HT server.
Add DNS entry for cas array – name to be 2010.domain.com IP of current 2010 server.
Check to make sure mailbox databases RPCClientAccess Server is pointing to CAS array 2010.domain.com
Thanks

Read this : http://www.kraftkennedy.com/blog/bid/102109/Configuring-NLB-for-Exchange-2010-CAS-Load-Balancing
Install new Exchange server, Create a CAS Array, Create NLB "VIP" IP, Configure NLB to include your 2 CAS/HUB Server, Do all your Exchange Shell commands to point RPC, ext to CAS Array, Point CAS Array.domain.com to point to the LB "VIP".

CSS and Oracle Load Balancing

Hi,
I have CSS in single arm deployment model. I have multiple servers load balancing on this CSS on port 80 etc. Today I am trying to load balance one Oracle server but I am facing problem with it.
Real servers are accessible on port 80 without any problem but when we are trying to access the same servers on VIP we are not able to see the web page.
real server http://192.168.17.12/irs.htm
real server http://192.168.17.14/irs.htm
real server http://192.168.10.37/irs.htm
VIP
http://192.168.200.58/irs.htm
Below is the configuration. I can do the telnet on port 80 and I can ping the VIP IP address.
I will only put 192.168.200.58 in browser I can see the oracle page but with the full URL i am not able to see it.
Though I have other oracle servers which I have load balance with the same configuration and I can access the web page.

Same setting I am doing for other servers and working fine only for these servers I am facing problem. Curently only one server is active in the configuration.
Kindly let me know what I am missing and how to fix the problem.
I have also attached the full configuration of CSS.

Hi,
My point of concern is that I did the same for Oracle server and this is working fine
http://192.168.200.95/forms/frmservlet?config=tp
only when I am doing the load balancing for
http://irs.enoc.com/irs.htm (This is not working).
By name and by IP address both are not working.
http://192.168.200.58/irs.htm (This is not working).
I dont have a option for TAC case is there a a way to fix the problem by apply other load balancing method. Is there something to do with the Circut VLAN. I didnt create the Circut VLAN 17 where this server is located.
I am doing almost 8 differenceservers load balancing in this CSS.
your expert opinion will definately help me.

HA and Load Balancing in Exchange Server 2010

Hi
My office just have 2 servers Exchange Standard 2010 (Licensed). I installed 3 roles on 2 servers (called Ex1 & Ex2). I configured Windows NLB for Hub Transport and Client Access. That 's fine.
But the maibox is seperated each server. Ex1 is main mailbox, so when Ex1 down, mailbox database will down too.
I 've read DAG solution but I just have 2 servers and it 's running WNLB. My office not enough cost to buy Hardware Load Balancer.
Does anyone have a solution for my problem ?
Thank you

Hi,
If you want to use DNS round robin, it is recommended to lower the TTL values of DNS records to 5 minutes.
DNS Round Robin has no automatic server failure detection. If a host goes down, Administrator will need to realize it, remove the DNS Record for the server that went down, and then clients will have to wait for the TTL value on the old DNS record to
expire.
Here is an article about DNS round robin for your reference.
