Server clustering over WAN

Hi
i am running two Microsoft servers. One is live and the other is in DR site, they are currently on differnt subnets, and for them to cluster, they send broadcast. what can i do for this two servers to talk to each other.
changing ip's on the router is out of the question.

What port number and protocol do they use. If you can assign them on the same subnet you can use IRB (integrated routing and bridging) over WAN.

Multicast server/client over wan

Ok, first of I am kinda new in programming network stuff.
Then I am gonna try to be clear in the things that I am trying to accomplish.
The environement.
I have a machine A that has 2 interfaces :

The two machine are on different networks.
My goal is to have Machine A send multicast data thru eth2 to be sent in the wan and to be received by Machine B on eth2 too.
Obviously the two machine are on separated networks.
I have tried everything I could but I cannot get machine B to pickup the messages sent by A. It worked fine when on the same LAN but not over WAN.
The multicast address that I use it 239.55.55.80 and the port 4445.
I think I have a problem to link the interface to my app ( I used setInterface and setNetworkinterface but nithing.) Also I cannot firgure out if the things that I am doing wrong are on the server or the client.
Here is the code for the sever and client.

TelePresence Conductor Clustering over WAN

Hi Cisco,
We want to deploy Clustering of 3 Conductor servers (2 local) and 1 over the WAN in a different DC.
Based on clustering guide 2.x and 3.x it states we need 30 ms RTT between Conductor servers, currently we have 50 ms RTT. Does Conductor 3.0 supports higher RTT? What are the implications of deploying Conductor with higher RTT?
http://www.cisco.com/c/dam/en/us/td/docs/telepresence/infrastructure/conductor/config_guide/xc3-0_docs/TelePresence-Conductor-Clustering-Unified-CM-Deployment-Guide-XC3-0.pdf
Thanks

Thanks Patrick,
I'm surprised this RTT is too low since Conductor just handle mostly signaling. Probably some under the hood DB requirement. I'm thinking of having 2 separate clusters, each in a different Data Center monitoring the same TPS. (Active/Standby), but CUCM will be configured to only select the "standby cluster" when the "closest" Conductor cluster is unreachable.
Do you know if TPS 4.X in remote manage mode supports this scenario?
Thanks

SQL Server Connection over WAN Link

I am planning
to setup a BlackBerry server and connect to a remote SQL Server over a
WAN link with 150+ms ping time. Is there a known tolerance for
SQL server connection latency? For example, I have been told by
RIM that ping time for Exchange should be around 35ms so if it is
higher, a BES should be placed next to the Exchange server. Any reply would be greatly appreciated.

There is no problem with slow connection :-)
You might get lots of waits in the SQL side (most likly there will be lots of
ASYNC_NETWORK_IO) which you can monitor using sys.dm_os_waiting_tasks and sys.dm_exec_requests. But if there is no disconnections then most small application will work OK

Windows server 2003 Remote desktop over WAN problem.

Ok so problem is there is a 2003 windows server in my office. Any computer phone etc. can connect to it via Remote desktop if they are in the LAN network. I have port forwarded 3389 , disabled firewalls , there is no antivirus software on the server.
BUT I cannon log in over WAN. Heres the problem.
I type in the WAN ip I connect with credentials.
This is what i get:
Connecting...
Negotiating credentials...
Then it just suddenly force closes.
Also tried from a Windows 8 PC , when trying to connect it INSTANTLY throws me an error saying:
This computer cant connect to the remote computer. If the problem continues contact etc..
No matter where i try , a pc , a laptop , a phone , a tablet it just force closes. I can see that the devices are able to see the server and are trying to connect , but the connection just force closes for no reason and no error is shown. Also I dont see
anything in the event viewer on the server. The credentials are correct also. And the port is forwarded correctly.
Where could the problem be?

Hi,
Thank you for posting in Windows Server Forum.
As you have commented that you have forwarded port correctly at windows end, but still suggest you to check whether you have port forwarded on Router which you are using for WAN connections.
Can your local system can make successful ping to the remote server from WAN connections?
For testing you can telnet <router ip> 3389 and if you get blank screen then it confirm that port has been forwarded.
It might happens that there is port assignment conflict taken place, so check with “netstat –a –o” and see port 3389 is not being used by other application, if that is the case then change the port.
You can refer following article for more troubleshooting steps (Point 2)
Remote Desktop disconnected or can’t connect to remote computer or Remote Desktop server (Terminal Server) that is running Windows Server 2003

CCX 8.5 HA virtual+physical server over WAN

Hello for everyone.
There is such task to deploy CCX 8.5 HA cluster - make one node on virtual maschine and second node on the physical server over WAN (wow! :).
So there some question. Anybody already does this deployment model? Will there any trouble in admistration and working in such way?
Will this configuration supported by Cisco?
Tried to find it out on cisco.com and google.com, but no success. So i think, if Cisco supports deployment on hardware, and on virtual so there no problem. But by hardware+virtual, there's a question.
So, any help and thoughts on this will be kindly appreciated!

Yes it's supported as long as they are equivelent hardware. In other words you can't use the 300 OVA on one side and an MCS-7825 on the other. You would need to use a MCS-7845. Personally I wouldn't recommend this. At some point MCS hardware will fall off the compatibility matrix forcing the customer to move to UCS at that time. CCX is rather finicy when it comes to backup/restore of a node in the HA cluster. That's a task I would avoid if you can.

Bonjour & disk sharing over WAN -Expert/Genius help required

*Goal: Learn how to connect to my USB hard disk over WAN, share drive with specific people.*
I'm trying to figure out how to remotely access my data on the external drive via connected via USB to my AEBN.
I've spent several hours dinking around with my router, trying to see if I can access the drive over the WAN. I haven't found any manuals, discussions, or K-Base articles that spell it out for me. Below is a list of things I've done. Please indicate whether they are relevant, and if possible what the procedure is. Thanks:
Conditions: I have a static IP address and through the DHCP tab I have assigned all attached machines a static LAN IP address.
*1. Airport>Base Station: Allow configuration over Ethernet WAN port.* I've checked this box and can remotely admin my AEBN from my PC laptop (XP) via the Airport Utility.
*2. Airport>Access Control: MAC Address Access Control.* I didn't know if this would help or hurt anything so I added the MAC address for all ethernet and wireless ports connected to my network and given unlimited or untimed access. +No noticeable difference.+
*3. Internet>DHCP: DHCP Reservations.* As mentioned above in conditions, I've assigned an internal IP address for each device's ethernet and wireless ports, based on the MAC address. +Seems like this and Access Control are redundant except for the time settings.+
*4. Disks>File Sharing:* Enable file sharing is checked, with accounts (configured), "Share disks over ethernet WAN port" is also checked, as is "Advertise disks globally using Bonjour". Not sure what to put in the bottom two fields (Workgroup and WINS Server) so they're blank.
*5. Advanced>Port Mapping:* I've assigned ports to my iMac for gaming and SSH access but I don't think these would effect the USB disk would they?
*6. Advanced>Bonjour:* "Use a wide-area hostname" is checked. My LAN network name is in the Hostname field, for Domain I just typed my WAN IP address, and I put something in for Name and Password.
I'd love any assistance to figure this out.
Lastly, how does Bonjour help over the WAN? Is there some sort of Bonjour application I open log-in, like FTP client software?

Since this discussion has now been resurrected...
The advice provided by chrisfenix will allow you to access the Airport drive from a PC on your private LAN.
The preceding discussion, however, was on the topic of accessing the Airport drive remotely over the internet. To do that, you could still use the advice provided by chrisfenix but substitute the public IP address of the Base Station. To find that out (and answer a question posed earlier in this discussion as well) just go to http://whatismyip.com/ from any computer on your own network.
To answer a question posed by the originator of this discussion - Bonjour is not at all necessary for remote access of the Airport drive. Those people who know how to use this feature will know what it is for and how to implement it - the rest of us can just pretend this feature doesn't exist.

Where to place files and folder in shared disk over WAN

Hello, I have a new Airport Time Capsule 3TB and I want to share my disk over WAN for remote accessing.
When I log to the server with my MacBook or iPhone, I see "Data" folder, and inside it I see my Time Machine backups.
My question is: where, -in the Time Capsule disk-, do I have to place the files / folders that I want to share over WAN. I am afraid to damage or corrupt my Time Capsule backups.
Thank you in advance.

It is not possible to partition the Time Capsule drive.....unless you.....
Pull the drive from the Time Capsule case....(voids the warranty)
Install the drive in a separate enclosure or caddy
Connect the enclosure directly to your Mac
Use Disk Utility to partition the drive
Reinstall the drive back in the Time Capsule
This is a lot of work....and should best be left to a technician.
All things considered, it would be better if you dedicated the Time Capsule for Time Machine backups only...and added another drive for your shared file needs, but few users seem willing to do this.

Does turning off DHCP remove option to Share Hardisk over WAN?

I'm a recent Apple convert. I have a new Macbook and have downloaded all recent updates.
I just integrated the Airport Extreme Base Station into my current home network. I have DHCP turned OFF in the AP because I am running a netgear router in my basement that is already connected to my Cable Modem. It needs to stay in the loop because I am using it to feed my XBox360, due to the issues related the Base station/360 interaction.
Here is my question... Does having DHCP turned off in the AP, remove the checkbox option in the "Disks" section of Airport Utility toolbar to "Share disks over Ethernet WAN port"? Its MISSING completely. I've seen many instructions that reference that phrase, but the only checkbox I have on that screen is one for using Bonjour. I want to connect a usb drive so I can have a central storage so my wife and I can share itunes/photos/documents. So could it be that option disappeared due to turning off DHCP or is there some other issue?

If you want to share your disks over WAN then you need to do the following:
1. Assign a manual IP address for your AirPort. You can do this by running AirPort Utility and under Internet you need to change Configure IPv4 from Using DHCP to Manually.
2. You need to port forward TCP port 548 on your main router to the IP address you assigned your AirPort. After doing this you will be able to access your AirPort disks by going to Finder, Connect to Server, and entering afp://<yourgatewayipaddress> You can find your gateway IP address by going to www.whatismyipaddress.com while on your home network.

A customer has several offices. Each office has a separate Exchange Server. The partner was considering a single Unity deployment connected to all of the exchange servers over the WAN, but has decided against that because the latency of the WAN is too high to do this. They are looking for a best practice way of deploying Unity for these multiple Exchange servers at multiple sites. This might mean a separate Unity server for each exchange server at each site .
However, we’re wondering if there is a better way to do this. With multiple unity servers we’ll likely have different prefixes for each unity server at each location . This is something that the customer would like to avoid. We’re wondering if there any best practices for a deployment like this that we can offer as options for the customer.

I have found some related information but really customer is altogether looking for an option away from Exchange networking over WAN.
I found:
“Multi-Site WAN with Distributed Messaging”
http://www.cisco.com/en/US/docs/voice_ip_comm/unity/5x/design/guide/5xcudg040.html#wp1077309
“Networking Options Requirements for Cisco Unity”
http://www.cisco.com/en/US/products/sw/voicesw/ps2237/prod_installation_guides_list.html
Design Guide for Cisco Unity also talk as much is there in the first URL.
Please Help!

This may be counter to your customer's desire or requirements but I must ask the question. Has the customer considered Unity Connection vs. Unity? Granted, Unity Connection provides integrated messaging whereas Unity is the unified messaging application; however, CUC has become Cisco's flagship messaging product over the last couple of years and I only see this expanding to be honest. So, for new installs - I push hard on Unity Connection. Sometimes, it's a sell but sometimes the customer has a hard requirement for UM and thus you have to go with UM. In your scenario, your customer could potentially save a LARGE amount of money as CUC is not dependent upon Exchange at all; however, you still have the option to tie into Exchange 2003/2007 as an external service where users can access messages in a 3rd-party message store and also access calendar data and so forth. The platform is very feature rich. Many of my current Unity customers are migrating off of the platform to the more "agnostic" CUC platform to avoid issues caused by such dependence on AD/Exchange. In addition, as Microsoft continues to develop and push it's own UM solution - integration for Unity is being forced to change (ex: changes to MAPI in 2010 caused problems for Cisco and required them to rework a bit of the underpinning integration points between Unity and Exchange). With CUC, you also have the flexibility to implment a dial plan within voicemail system itself...not to mention it is extremely scalable.

There is no "Share disk over WAN" checkbox

Hello i do have no checkbox for "Share disk over WAN" on my airport settings for TC. What should i do? I just want to access my TC over internet.
this is back to my mac option from settings. It says 'set router' which is doubtful to me.
and here there is no checkox for it.
note: it is 7.6.1

What kind of broadband do you use?
BTMM should work fine with any router that uses upnp or nat-pmp. You do not require an apple router.
If you want to access the TC from internet.. that is possible manually.. in fact it works really well.
You need to set up a dynamic dns account.. almost all routers will have a client.. pick a service for which you have a client.. (unless you have static public IP which is even better).
Then simply port forward AFP protocol TCP port 548 to the TC.. which is in bridge.
Remotely you access by typing in connect to server... AFP://dynamicip or staticpublicIP.
Just google remote access to TC there are plenty of discussions and youtube video of how to do it.

Difference between Share Disks over WAN vs. over Internet using Bonjour?

I would like to find out the Difference between selecting the "Share Disks over WAN" option only vs also selecting the additional "Share disks over Internet using Bonjour" option. Any info is greatly appreciated! Thanks!

you can access drives plugged into your AirPort extreme base station from outside the network by typing in the IP address of the modem/base station in the "Connect to Server" dialogue on the Finders "Go" menu (or press Command+K when in Finder). You can get the base station IP by opening the AirPort Utility from your utilities folder, and click "manual setup" at the very bottom of the summary tab should be the IP address given the base by your modem.
As long as you have "Share Disks over WAN enabled" when you connect using the IP from another location you will be prompted to authenticate to the AirPort Base station and if authentication is successful you will be prompted to mount a disk (the disk plugged into your AirPort base station should be the only available disk to mount).
Keep in mind you must give out the Base Station password unless you allow guest connections to the disk.

Could you please share experiences Windows 7 64 bit InDesign CS6 Std opening and working with 100-120MB files over public ISP WAN using VPN?
Right now very often we experience unresponsive screens of CS6, while nothing happens during 10 minutes and ID needs to be closed from Task manager.
Usually this is a result of some action, ID button or mouse click.
Background is, that enterprise has a central InDesign file depository, where ID files can be accessed and worked with from different countries.
While transfer speed of our local ISP is 20/10 Mbit, depository side server real life bandwidth and server access speeds are variable and unknown.
Is there some option to set up in local PC, which could improve performance over WAN?

I agree with Bob. For best performance, I'd recommend copying the files locally if possible. Although it's very common to work over a LAN, I beleive that Adobe's official policy is that they don't support working over a network. What this means is that if you call Adobe support with a problem, they'll have you copy the file locally. If that solves the problem, they're done. This is their way of avoiding network troubleshooting for hundreds of different types of servers.

CCX 8.5 in HA over WAN on Island Mode

Hi guys,
Does anyone know what will happen with CCX 8.5 in HA over WAN configuration goes to island mode?
So consider the following setup
Site A Site B
CUCM Node --- WAN --- CUCM Node
CCX Primary CCX Standby
Each site have their own local voice gateway and sets of agents.
The SRND covers that if 10 consecutive heartbeat is lost then a failover will be triggered.
However the SRND does not cover the scenario if the WAN is totally cut and Site A and Site B is completely isolated from each other.
Does anyone know what will happen in this situation? Will both CCX Node become Primary and operate in its own right (just like Unity Connection cluster when they go to island mode)?
Kind regards
Daniel

Daniel,
Here is more of a "step by step" to your question:
Page 68:
http://www.cisco.com/en/US/docs/voice_ip_comm/cust_contact/contact_center/crs/express_8_5/design/uccx851srnd.pdf
When the WAN link has a clean break:
and by clean break I mean it goes down and stays down, it does not
flap or provide intermittent connectivity
1) The CAD agents will connect to UCCX server that they can communicate with
2) The UCCX servers will connect to the CUCM Node that they can connect
to for call processing
3) The calls that get to the respective UCCX servers will go to the
respective agents
When the WAN Link is restored:
1) The Nodes will decide which node is more "qualified" to become the
master node, this is generally Node 1 aka the first node that was built
in the cluster
2) The CAD Agents connected to the node that becomes the secondary will
fail over to Node 1 to begin accepting calls from it
3) All of the calls that the new master Node were processing will not
have any negative affect as they will continue to be processed by UCCX
4) The calls that are in queue for the node that becomes the slave in
the cluster will be dropped

Performance over WAN

Hi,
We are using Forms based application deployed over 9iAS Rel2. We uses IE to access the application and Jinitiator installaed on client machine.
Presently Database and application server are on the same city for example CITY A. All the application users also on the same city(CITY A).
We have a plan to move the Database and application server to another city(CITY B) and keep the users in the CITY A.
Application validate each field level and each validation will goto Database and come back.
I would like to know whether we will have any performance issue,latency issue with the new approach.
Pls let know.
Thanks.

I am trying to pull LOB data from db and transmit it over WAN networl and I noticed that its performance is reduced to greater extent compared to client server model. WAN/LAN/etc does not dictate whether or not the client-server model applies.
Client-server is a software architecture.
It is not a hardware architecture..the client component can reside on a different h/w platform than the server component.. or it may not (can reside on same h/w platform as the server s/w component).
It is not a network architecture... the client component may use a network protocol to communicate with the server component.. or it may not (can use IPC instead of IP).
Can anyone plzz help me to guide to optimise performance of LOB fetch and network communication.From the application side, the only real things that you can govern is the amount of data to transfer (minimise it for performance) and the sizes of the data payload in the network packets (maximise it for performance).
In other words, only send the minimal data from the server that is needed by the client. When doing so, make effective use of "+fetch sizes+" (properties like InitialLOBFetchSize(), FetchSize() and RowSize() ).
