SLP Advice for Multi Site

Hi
I did post another SLP query related to this but received no responses. I have been reading up on SLP setup, we have had our existing SLP setup in place for a number of years, however we have had issues where if a site link is off the site cannot log in locally at all - it is obviously trying to locate resources in a container in does not have a replica of.
When our SLP was setup the resources were placed at the central site under the central site's container. I am wondering if a) it is OK to move the SLP scope container (and DA object?) to root and then place a root replica at each WAN site? (I have read you should not place a local DA at each site though had considered this also) and b) should I place a backup SLPDA somewhere incase there is a problem with the server housing the DA (which has also happened to me - and sites could not log in at all while it was restarting!) Can I point to 2 in my server and client configs?
We will be moving to OES2 next year but I need to make sure this keeps operational as efficiently as possible until that time.
Advice from a Novell expert would be much appreciated
Thanks

I would be interested in knowing more about this as well if anyone answers....I would not hold my breath. :-)
We have 10 partitions/containers which are scattered location-wise. We have 1 server in each container and are running slpdas on 2 servers in HQ pointing to a central scope. However, I have found that if a link isolates one of the containers from talking to the HQ container with the scope and slpda, then login is not possible from the local isolated container. I would like to set up slp to mitigate this if possible. We use SLES10/OES2 so this is not as easy as it was with NetWare 6.5....

Deploy Exchange 2013 Edge Transport Server for multi-site environment

Hi,
I have a multi-site Exchange 2013 environment. The configurations are as below.
Active Directory Sites and Exchange Servers.
SiteA - EXMB1 & EXCAS1
SiteB - EXMB2 & EXCAS2
SiteC - EXMB3 & EXCAS3
All sites are connected via VPN. (Good speed. No latency issues)
All the three Mailbox Servers are in DAG. Only one mailbox database. All servers running Exchange 2013.
I am planning to deploy Edge Servers in the infrastructure (I am doing it for the first time). Normally, it will be in DMZ.
Now, I can deploy 2 Edge Servers for reliability.
Question.
1. Can I deploy 2 Edge Servers and create subscription to all the mailbox server in 3 different site? Or, is it like one edge server can make subscription to only mailbox servers in one Active Directory Site? I am not sure about this and could not find much
information from TechNet.
One Edge Server can make subscription to all 3 mailbox server in 3 sites. Similarly, I can make the subscriptions in the second edge server as well. Configure 2 external MX records with the same priority so that there will be some load balancing.
Also, in such a case if the mailbox database become active from a different site, I need not make any new changes to the Edge Servers right?
2. If the first way is not correct, I will have to deploy 1 Edge Server each for each of the Active Directory Site. (In DMZ only, not in domain)
Make Edge Subscription to the mailbox server in corresponding site.
Make 1 MX record and point it to the Edge Server which is subscribed to the Mailbox Server from which the Database is Active. The problem is, every time will have to change the DNS record when ever the database copy is activated from a different mailbox
server. And the issues with propagation.. delay..
I am not sure which of the above 2 ways will work. Appreciate suggestions from anyone who have previous experience with similar infrastructure.
Thanks in advance. :)

Hi
One or more Edge Transport servers can be subscribed to a single Active Directory site. However, an Edge Transport server can't be subscribed to more than one Active Directory site. If you have more than one Edge Transport server deployed, each server can be
subscribed to a different Active Directory site. Each Edge Transport server requires an individual Edge Subscription.
A subscribed Edge Transport server is associated with a particular Active Directory site. If more than one Mailbox server exists in the site, any of them can replicate data to the subscribed Edge Transport servers.
I don't think there is a solution to subscribe edge servers for more than 1 site. Edge Servers can be scoped only to one site.

Manually editing NetworkConfig.xml for multi-site VPN

I'm designing a network comprised of on-premise, Azure East US VNet and Azure North Central US VNet. East will be my production VNet and North Central will be backup/dev. I want them routed together as well and accessible via on premise-VPN with RRAS and
using point-to-site. I have successfully made all these connections individually in test scenarios but never simultaneously as the portal only has one field for a site-to-site VPN and this scenario requires two.
I understand it's possible to create this design by editing the NetworkConfig.xml file. However, it's confusing to me why even when making small or no edits to the NetworkConfig.xml file the portal tells me my existing networks will be deleted and re-created.
Does that take out my gateway IPs, etc as well? If so, I'll have to re-enter all the new IPs in RRAS and basically start from scratch. I have a few test VMs in each VNet as well to test connectivity between sites. I'm guessing those would have to go too or
the VNets wouldn't be able to be deleted in the first place.
Also, an unrelated static network that I make no changes to in the xml file says it will be updated when I upload even an unchanged NetworkConfig.xml. This is concerning as it's hard to know what downtime and issues I'm going to cause if I save the new file.
Any tips would be appreciated. My sense is you have to have your whole design in your head first, get it into the NetworkConfig.xml and then move forward with creating the gateways and entering your IPs into RRAS or whatever your VPN tool my be. Being able
to edit existing VNets, specifically adding additional site-to-site VPNs after they are in use would really be helpful. Perhaps this is possible and I'm missing something.

Hi,
Firstly, you need to delete the gateway and all resources in the virtual network before you delete it.
In addition, based on my experience, you just need to add the local network sites parts into the network configuration file for a multi-site VPN connection. If you are afraid that the virtual
network configuration would be wrong after importing, I recommend you to keep the previous network configuration file as a backup. In addition, I am glad to help you with the network configuration file, you can also share me the whole network configuration
file and tell me some more detailed information about your requirement. (Please hide the Public IP addresses for your VPN gateways and VPN device.)
Meanwhile, you can also refer to the link below for reference:

DNS for multi-site same server scenario

I setting up the DNS for a multi-site server, I understand that the second (and subsequent) site needs to be an alias of the first.
I have tried setting up the DNS entires as aliases (CNAME) as well as A records to no avail.
I am sure that it is me, but what am I missing?
I am unable to access these sites locally so I am positive that no on can access the site outside of the firewall.
Thank you!

There's not much detail there to go on...
In general, yes, you should create one A record for the host, e.g.:
webserver.domain1.com. IN A 192.168.1.2
Then other domains should, ideally, point to this via a CNAME:
www.domain2.com. IN CNAME webserver.domain1.com.
Technically, it's OK to have additional A records pointing to the same IP, it just makes it a little harder to keep track of, and changing server addresses is a PITA (there's only one place to change it when using CNAMEs).
As to what your issue is, there's no way of knowing without seeing your domain records and the name server logs. bind is pretty good about logging errors and often provides a good clue when things are amiss. If I had to hazard a guess, though, I'd say you missed a trailing . on the CNAME records, but that's largely a shot in the dark without more information.

Use configuration management for multi site application

Hi,
My client develop an application multi site with designer 6i. We want to use the configuration management .
The application will be deploy in 10 sites, but not necessary with the same version of the application.
You want to control that with the configuration management of designer 6i.
Someone has some experience with that ??
Can i have some reference or detail experience ??
Thanks a lot
chris

I asked this sort of question for creating a live and a test release of an application. The answer I got was to create a configuration of based on my application and then to create an applications based on the the versions of the configuration.
Then, I could check the configuration against the main workarea to tell me what was out of date.
I could also use the configuration wizard to create a new version (of the configuration) selecting the versions of the modules I wanted (ie: newer ones). Then I created a new version of the release application using the new configuration.
Finally, in the command tool I can select the release work area which will extract correct module versions (I have the .fmbs) and I can compile a release.
I guess your solution here is to have a main workarea with all the source, then a configuration of that and then one release application for every site. Each release application could use a different version of the configuration - depending on how up to date they are.

Simplifying printers for multi-site users

Windows 2008 R2
Windows 7 Enterprise
Topology: Central network with about 50 users/computers and 5 servers. 25 remote sites, 2-4 users/computers per site (no servers at the sites). Each site also has one network printer.
Currently all sites have the same IP scheme (we use DirectAccess for file access so unique subnets are not required). All of the printers are the same model and have the same static IP. So no matter what site a roaming user goes to printing works with no
confusion.
Some new technology is being implemented that will require us to make unique subnets (which is actually desirable for obvious reasons). At the same time we will be implementing site-to-site VPNs, so there will be full connectivity to AD/central site.
So, here in lies the problem. Our super simple printing solution, now will not work. Some users roam to a dozen sites or more, will they have to have that many printers? Then they have to make sure to print to the one that is online/ready? Is there a GPO
setting to hide offline printers or something? I wouldn't care if there were 25 print queues as long as only available printers were displayed. I see that there is some location aware printing features of AD/W7, but I am concerned all the offline printers
will confuse users.
Any ideas?

SQL Server 2012 Multi-Site clustering with 2 nodes for HA and DR

Usually we setup 2 Node Prod cluster for Local HA and 1 or 2 Nodes in other data centre for DR
Given that we have an option to setup multi-site / multi-subnet clustering from SQL 2008 R2/2012. I am planning to use just 2 nodes, 1 in prod data centre and 1 in DR data centre with 2 or 3 instances. This will act as both HA and DR solution.
I would like to know if this solution is good, and any disadvantages, any best practices, etc.? By implementing this I can save some cost on physical servers.
Following will be configured:
* Will be using different subnets, quorum on different server with "Node and File Share Majority"
* All virtual IPs will be registered for virtual name, and Subnetdelay, Subnet threshold will be modified accordingly
* All nodes on same domain
* Use SAN Disk with replication to DR site

SQL 2008 R2 doesn't support multi-subnet clustering. You would still need 3rd party component like VLAN and Disk Replication. SQL 2012 is the first version to support multi-subnet clustering without using VLAN. you would still need disk replication hardware/software.
Taken from my book
Since nodes are often located in two different data centers at geographically dispersed locations, there is no shared storage between the nodes in a multi-site cluster. Clustering across two different data centers provides a higher level of availability and
protection at the storage level as we have more than a single copy of the data.
For SAN replication technology implemented in such clusters, the main activity is to keep data replicated between the sites. Typically, if we have nodes on two different sites, we would have two different network infrastructures and the nodes would be in
different subnets. In such cases, if we are on a SQL Server version before 2012, we need to use third party VLAN (Virtual LAN) technology so that one IP address travels between two sites. This is called wide-IP. Companies hesitate with this solution because
of the need to buy a third party solution to deploy the VLAN. Using VLAN technology means the same IP address would failover to the remote site in case of a local site disaster. Network administration might consider this as an overhead to maintenance and an
extra piece of the networking component that needs to be secure.
With SQL Server 2012 we do not need to use stretch VLAN technology but SAN replication is still needed for multi-site clustering. The OS version for this can be from Windows Server 2008 R2 and above. In this deployment, we can have a SQL virtual network
name having an “OR” dependency on two different IP addresses. One address would be representing each subnet. With the “OR” dependency, if IP1 or IP2 is online we just use the network name. This is one of the Enterprise Editions only features.
Other option which you can think of, without using 3rd party solutions would be AlwaysOn Availability Group. I have written details about it in my book.

Windows 2008 R2 Multi-Site (geo) Cluster File Server

We need to come up with a new HA file server (user drive data) solution complete with DR. It needs to be 2008 R2, cater for about 25TB of data, and be suitable for 500 users (nothing high end on I/O). I don't want to rely on DFS for any form of resilience
due to its limitations for open files. We have two active-active data centers (a third can be used for file share quorum).
We could entertain:
1)
Site1 - 2 x HP ProLiants with MSA storage, replicating with something like DoubleTake to a third HP Proliant at site 2 for DR.
2)
Site1 - 2 x HP ProLiants with local storage and VSA or HP StoreVirtual array (aka LeftHand), using SAN replication to site 2 where we could have a one or two node config of the same setup.
Ideally I would like all 3/4 nodes in these configurations to be part of the same multi-site cluster to ensure resources like file shares are in sync. With two pieces of storage across this single cluster (either a DoubleTake or SAN replication to local
disks in DR) will this work? How will the cluster/SAN fail over the storage?
We do have VMWare 5.0/1 (not 5.5 yet). We don't have Hyper-V yet either. Any thoughts on the above, and possible alternatives welcome. HA failover RTO we'd like in seconds. DR longer, perhaps 30 mins.
Thanks in advance for any thoughts and guidance.

For automated failover between sites, the storage replication needs to have a way to script the failover so you can have a custom resource that performs the failover at the SAN level before the disks come online.
DoubleTake has GeoCluster which should accomplish this. I'm not sure about how automated Lefthand's solution is for multi-site clusters.
VMware has Site Recovery Manager, though this is really an assisted failover and not really an automatic site failover solution. It's automated so that you can failover between sites at the push of a button, but this would need to be a planned failover.
RTO of seconds might be difficult to accomplish as you need to give the storage replication enough time to reverse direction while giving the MS cluster enough time to bring cluster applications online.
When planning your multi-site cluster, I'd recommend going with 2 nodes on each site and then use the file share witness quorum on your 3rd site. If you only had one node on the remote site, the primary site would never be able to failover to the remote
site without manually overriding the quorum as 1 node isn't enough to gain enough votes for quorum. With 2 nodes on each site and a FSW, each site has the opportunity to gain enough votes to maintain quorum should one of the sites go down.
Hope this helps.

Windows Multi Site/Geo Cluster

Hi,
I am looking for a Multi Site Cluster solution for File Server and SQL DB. Could you pls help with any case study of solution approach for building the Multi Site cluster using Windows 2012 ?

General suggestion: if possible use async replication rather then sync. Sync mirror puts high stress on WAN and lack of reliable channels can lead to cluster either non-operational (all WAN links down so cluster node w/o quorum kills itself) or brain split
issue (all WAN links down so separated cluster nodes continue working AS IS damaging data). For async replication you may look @ DFS-(R) as a file server, see:
Distributed File System
http://technet.microsoft.com/en-us/library/cc753479(v=ws.10).aspx
For SQL Server look at AlwaysOn in async way, see:
AlwaysOn for SQL Server
http://msdn.microsoft.com/en-us/library/ff877884.aspx
Availability Modes
The availability mode is a property of each availability replica. The availability mode determines whether the primary replica waits to commit transactions on a database until a given secondary replica has written the transaction log records to disk (hardened
the log). AlwaysOn Availability Groups supports two availability modes—asynchronous-commit mode and synchronous-commit mode.
Asynchronous-commit mode
An availability replica that uses this availability mode is known as an asynchronous-commit replica. Under asynchronous-commit mode, the primary replica commits transactions without waiting for acknowledgement that
an asynchronous-commit secondary replica has hardened the log. Asynchronous-commit mode minimizes transaction latency on the secondary databases but allows them to lag behind the primary databases, making some data loss possible.
Of course it's possible to configure SMB 3.0 failover file share on geo-separated sites and use Failover Cluster Instances for SQL Server in the same scenario. Just make sure you configure reliable witness (you'll have to do it for SQL Server AlwaysOn either
way...) on some third location. For file server I'd suggest to use some sort of a software replication in sync way instead of a geo-distributed physical shared storage. That one is for SQL Server and SteelEye Data Keeper but you can use any Windows-native
(preferred) software as well. See:
SQL Server Geo-Cluster with software shared storage

Multi-sites paging

Hi Gurus,
Did anybody implemented InformaCast paging sucessfully for multi-sites over FR or MPLS? I mean a InformaCast server only in Central site, can remote site do paging? Thanks.

Are you looking to page out over the speaker of each IP phone, or over loud speakers?
In our facility, we use just the features built into call manager. I have built a partition called paging. I added that partition to the appropriate calling search spaces, and created a dn #10. I attached the #10 dn to a fxs port at the gateway, which I connected to a Bogen UTI-1 (http://www.bogen.com/products/pdfs/selfamplifiedpdfs/UTI1m.pdf). This was connected to a series of loud speakers through the paging environment.
I would think that you could do something similar by creating a DN on each persons phone with the config of auto answer speakerphone. then, when you dial that access number, it would pick up all lines on speaker. (Kind of powerful, be careful and test before deploying globally).

Wireless site survey planner tool for multi floor office building

Hi,
I'm looking a wireless site survey planner tool for multi floor office building to estimate the number of APs and location. Not the site survey after install APs.
AigMagnet is excellent for single floor but cannot provide multi floor scenario via planner feature even it merging capable with site survey after APs installation.
Any tools can provide the planner tool for multi floor office building?
Thanks in advance,

Cj
If you are looking for an AP estimate you can simply do the sq feet divided into the grade of wireless. For example
You have a 100,000 feet building. All 100,000 sq feet will be wireless.
Data 5,000 - 6.000 sq feet per AP or 100,000 / 5,000 = 20 access points
VoIP 2,500 sq feet per AP or 100,000 / 2,500 = 40 access points
I always like to pad it by another 10%.
I hope this helps â¦

Apple TV account control for multi business sites?

Asking for advice for Jabber deployment - multi CUCM cluster\AD domains

I would like some design advice for deploying Jabber and CUPS in our company. We have 2 locations, west coast (SiteA) and east coast (SiteB). Each site have their own CUCM 7.15 clusters, Unity clusters, AD domains (trusted, but not in the same forest).
At SiteA I have setup CUPS (8.6.3.10000-20) and jabber and have it working great.
I would like to setup CUPS\Jabber for SiteB, but they need to be able to IM\call\etc to SiteA (And vice-versa).
SiteA and SiteB both have CUCM LDAP sync turned on, and LDAP directory synced with both domains (although SiteA cannot authenticate to CUCM at SiteB, and vice-versa due to the fact you can only LDAP sync authentication with one domain, CUCM user database contain users from SiteA and SiteB).
We have SIP trucks setup to pass internal calls and line status(BLF) between the trunks, and can communicate via internal extensions just fine.
The problem I’m running into is my jabber-config files uses the EDI directory – which can only look at one domain, so I cannot search the other domain. I believe changing to UDS fixes this, but I understand it would require me to upgrade both CUCM clusters to 8.6.2 - unless I’m mistaken.
I’m aware the desktop sharing will not work until CUCM is upgraded to 8.6.1 or 8.6.2.
I’m wondering if anyone has any advice, or can confirm I’m on the right track. Thanks in advance!

The thing that's important to understand is how CUP and Jabber build the XMPP URI. The URI has a left- and right-hand side; the left is the username while the right is the XMPP domain. CUP uses the LDAP attribute specified in CUCM's LDAP System page, sAMAccountName by default, for the left-hand-side. The right-hand side is the FQDN of the CUP cluster. Jabber must use the same values as CUP when displaying search results. Take note that nowhere in this process does the entire XMPP URI originate from the directory source.
In your case you have two separate CUP clusters in two separate domains. This won't work because when a user searches for a contact in the directory using Jabber, the client will build the XMPP URI as [email protected]. Even if you got the other domain's user objects into the search results the right-hand-side of the URI would be wrong and the presence subscription would never succeed since the other cluster is in another domain. As such your first task must be to move the CUP clusters into the exact same fully-qualified DNS domain. Once this is done you can use Inter-Cluster Peering to build a larger XMPP network in which all users have the same presence domain. If you intend to do Inter-Domain Federation in the future this must be your public DNS domain, not your internal active directory domain. If you use a non-public DNS domain TLS handshake will never succeed for inter-domain federation requests.
Once you have Inter-Cluster Peering in place you can use Active Directory Lightweight Directory Services (the new name for ADAM) to front-end both forests. Both CUCM clusters would need to import the full list of users representing both domains and the sAMAccountNames must be unique across both domains.
Finally, you can instruct Jabber to use UDS and query it's local CUCM cluster which will be able to return a search result from both domains. Since the CUP clusters are peered in the same domain the XMPP URI can be built properly, the presence subscription can be routed to the correct cluster, and life will be good.
By this point hopefully it's clear that EDI won't cut it since it would be limited to only returning search results from the local forest.

Creating multiple subscriptions for collaborative site collections under same OU in multi-tenancy

Hi,
We have an application that creates host based collaborative site collections and MySite Host site collections. We have created two separate web applications for hosting collaborative site collections and Mysite host based site collections as recommended
by MS.
For creation of collaborative site collections, we are creating separate site subscriptions for separate site collections. For example, if a tenant has two collaborative site collections as CSC1 and CSC2, then two site subscriptions are created for two CSCs
under the same tenant. The reason behind the implementation is as follows:
There is a 1:1 mapping with the featurepack and site subscription. Now if two site collections are created under the same site subscription, then altering the feature pack of any site collection will affect the other one. Whereas, if separate subscriptions
are created fro separate site collections, then altering the featurepack of any site collection will not affect the other site collections.
Now, my concern is, will the basic functionalities of SharePoint, like search, user profile, etc, will break for the above implementation. Is there any technical hazard for the above implementation.
A quick response is appreciated, as we need to deliver a customer ASAP.
Thanks in advance,
Arnab

Search and UPSA would be part of the Site Subscription, so I'm unsure as to what you're specifically asking.
