Best practice for High availability design, HSRP

Hi,
I am planning to create High Availability for LAN to WAN connectivity.
But I want to know your opinion about the best way how to do this. I googled for a solution/best way how to do this, but I didn't found in my opinion right answer.
The situation:
I have 2 3945E Routers and 2 3560 switches. The design that I am planning to implement is below.
The main goal is to have redundant connection, whatever one of the devices will fail. For example, if the R1 will fail, R2 should become active, if the SW1 will fail, the SW2 will take care about reachability and vice versa. The router 1 should be preferred always, if the link to ISP isn't down, because of greater bandwidth. So why am I drown 2 connections to 2 separate switches. If the SW1 will fail, I will still have a connection to WAN using R1 router.
The Router interface should be configured with sub interfaces (preferred over secondary IP address of interface), because more than 10 subnets will be assigned to the LAN segment. The routers have 4 Gi ports.
HSRP must be enabled on LAN side, because PC's on LAN must have redundant def. getaway.
So, the question is - what is the best and preferred way to do this?
In my opinion, I should use BVI and combine R1 routers 2 interfaces in to logical one and do the same for the R2.
Next, turn the router in to L3 switch using IRB and then configure HSRP.
What would be your preferred way to do this?

Hi Audrius,
I would suggest you to go with HSRP. GLBP you will use where you want load balance.
I think the connectivity between your Routers (3945) and switches (3560) is gigabit connection which is high speed. So keep one physical link from your switches to each router and do HSRP on those router physical interfaces.
In this way you will have high availability like if R1 fails then R2 will take over.
Regarding the config see the below which I have for one of my Customer DC.
ACTIVE:
track 1 interface GigabitEthernet0/0 line-protocol
track 2 interface GigabitEthernet0/0 line-protocol
interface GigabitEthernet0/1
ip address 10.10.10.12 255.255.255.0

Question on replication/high availability designs

We're currently trying to work out a design for a high-availability system using Oracle 9i release 2. Having gone through some of the Oracle whitepapers, it appears that the ideal architecture involves setting up 2 RAC sites using Dataguard to synchronize the data. However, due to time and financial constraints, we are only allowed to have 2 servers for hosting the databases, which are geographically separate from each other in prevention of natural disasters. Our app servers will use JDBC pools to connect to the databases.
Our goal is to have both databases be the mirror image of each other at any given time, and the database must be working 24/7. We do have a primary and a secondary distinction between the two, so if the primary fails, we would like the secondary database to take over the tasks as needed.
The ability to query existing data is mission critical. The ability to write/update the database is less important, however we do need the secondary to be able to process data input/updates when primary is down for a prolonged period of time, and have the ability to synchronize back with the primary site when it is back up again.
My question now is which replication technology should we try to implement? I've looked into both Oracle Advanced Replication and Dataguard, each seems to have its own advantages and drawbacks:
Replication - can easily switch between the two databases using multimaster implementation, however data recovery/synchronization may be difficult in case of failure, and possibly will lose data (pending implementation). There has been a few posts in this forum that suggested that replication should not really be considered as an option for high availability, why is that?
Dataguard - zero data loss in failover/switchover, however manual intervention is required to initiate failover/switchover. Once the primary site fails over to the standby, the standby becomes the primary until DBA manually goes back in and switch the roles. In Oracle 10g release 2, seems that automatic failover is achieved through the use of an extra observer piece. There does not seem to be anyway to do this in Oracle 9i release 2.
Being new to the implementation of high-availability systems, I am at somewhat of a loss at this point. Both implementations seem to be a possible candidate, but we will need to sacrifice some efforts for both of them also. Would anyone shine some light on this, maybe point out my misconceptions with Advanced Replication and Dataguard, and/or suggest a better architecture/technology to use? Any input is greatly appreciated, thanks in advance.
Sincerely,
Peter Tung

Hi,
It sounds as if you're talking about the DB_TXN_NOSYNC flag, rather than DB_NOSYNC.
You mention that in general, you lose uncommitted transactions on system failure. I think what you mean is that you may lose some committed transactions on system failure. This is correct.
It is also correct that if you use replication you can arrange to have clients have a copy of all committed transactions, so that if the master fails (and enough clients do not fail, of course) then the clients still have the transaction data, even when using DB_TXN_NOSYNC.
This is a very common usage scenario for Berkeley DB replication/HA, used to achieve high throughput. You will want to pay attention to the configured ack policy, group size setting, setting of the 2SITE_STRICT option (if group size == 2).

High Availability design/upgrade

Hi,
We’re looking to upgrade our Production SQL Cluster infrastructure. Currently we are running on old hardware and software….We currently have two nodes in the cluster. 2-Proliant
DL380 Gen5 servers connected to our HP MSA2000 for shared storage(Direct Attached Storage) using a SAS cable with 1 terabyte. Windows 2008 R2 enterprise with Clustering turned-on and SQL 2005 server. The DB isn't that
big, but it is crucial to our company…. I was curious to get some opinions what would be our best options to upgrade….. We have two spare physical Proliant DL380 Gen 8 servers w/ 64 gigs of ram and total of 1.5 terabyte of worth of disk space. We would
have all the HD bay’s with HD’s therefore no need for a new HP MSA /direct attached storage….. So should we go with Windows 2012 Enterprise with SQL Enterprise and turnon SQL Always on Availability Group? Or any other recommendations? Any suggestion
and comment would be greatly appreciated.

Hello,
SQL Server AlwaysOn Availability Groups requirement Windows Server Failover Clustering (WSFC) clusters.Each availability replica of a given availability group must reside on a different node of the same WSFC cluster
Based on your description, it seems that you had two node cluster with Windows Server 2008 R2. If so, you should install windows 2008 R2 SP1 for supporting SQL Server AlwaysOn Availability Groups.

Oracle EBS R12.1.3 High Availability with RAC 11g on VMWARE

Dear All,
Our customer requirement is of high availability and good utilization of hardware for EBS R12.13 implementation.As per our strategy we want to use Oracle VM(I think it doesn't require any licensing) , RAC 11gR2 and appstier load balancing.We have only two servers to achieve all these.One one node there will be two VMs one for dbtier and another one for appstier and same will be on second server.So this way we will be having four virtual machines on two physical nodes.For all these we will use OEL Linux as Operating system
Please share your experiences , if above deployment model is correct or need further enhancements.

SharePoint 2013 High Availability - BI Semantic

SharePoint 2013 High Availability
Hi all,
Settings
Two Sites connected via tunnel, no issue in networking – Single farm
SQL2012, two DB with mirroring
SharePoint 2013, two servers in the farm, each server is APP & WEB
Issue, this has been designed against full site failure (e.g. losing connection to other site, which means losing 1 SQL and 1 SP server)
When users try to view some reports from the BI page, they can’t , we have confirmed that SQL mirrors are failing correctly, the issue (we think to be to access the SharePoint reporting services DB which we have mirrored as well), any help will be great.
Regards

Okay, if you've validated that you have the 1Gbps and 1ms over 10 minutes average, then you're in a supported scenario. How did you configure the SSRS databases to use mirroring within SharePoint? With SSRS databases, you'll need to use PowerShell:
$database = Get-SPDatabase | where {$_.Name -eq "ReportingServiceDbName"}
$database.AddFailoverServiceInstance("InstanceName")
$database.Update()

Multi Site SQL High Availability group

Hi,
We have our primary Data Centre where we have 2 MS SQL 2012 Enterprise Servers and 2 SharePoint 2013 Enterprise servers.
We have SQL High Availability group implemented on our primary Site (Site A)
Site A has subnet of 192.168.0.0.
We recently added a new DR Site (Site B). Site B we have MS SQL 2012 Enterprise Servers. Site B have a subnet of
172.1.1.0
Both sites are connected via a VPN Tunnel. MS SQL 2012 Enterprise Server on Site B has been added in have SQL High Availability
group of Site A.
SQL High Availability group have 2 IPs 192.168.0.32 and 172.1.1.32. SQL Listener have 2 IPs 192.168.0.33 and 172.1.1.33
We want to make sure that if Site A completely down then Site B work as an active Site. But when Site A down we are unable
to ping High Availability group and Site B is unable to work as active site. SQL and SharePoint services are completely down.
Site A has AD(Primary Domain Controller) and Site B has ADC(Additional Domain Controller).
Site A has witness server.
We are using Server 2012 Data Centre
Please suggest.

SharePoint is not the same as any other applications. The DR site has to be a completely different farm from your production. This means that the SharePoint_AdminContent and config databases on both farms are different and should not be included in the Availability
Group (they do not support asynchronous Availability Group.) Only content databases and other SharePoint databases supported in an Availability Group should be included as per this
TechNet article. Have a look at this
blog post for your networking configuration.
The reason your Windows cluster service goes down in the DR data center when the when your primary data center goes down is because the cluster has no majority votes. You have 4 available votes in your cluster - 3 in the primary data center in the form of
the 2 Availability Group replicas and the witness server and 1 in the DR data center. If the Windows cluster does not have majority of votes, it automatically shuts down the cluster. This is by design. That is why when this situation happens, you need to force
the cluster to start without a quorum as described in
this article (Windows Server 2012 R2 introduced the concept of dynamic witness and dynamic quorum to address this concern.) By default, the IP address of the Availability Group listener name will be registered on all of the DNS servers if the cluster is
running Windows Server 2012 and higher (this is the RegisterAllProvidersIP property that Samir mentioned.) However, you need to flush the DNS cache on the SharePoint web and application servers and point them to the correct IP address on the DR server after
failover. This is because the default TTL value of the Availability Group listener name is 20 minutes.
It is important to define your DR strategies and objectives when designing the architecture to make sure that the solution will meet your goals. This will also help you automate some of the processes in the DR data center when failover or a disaster occurs.

Hi,
There is not a High Availability solution for DPM such as clustering DPM servers. The options you do have are
Primary and Secondary DPM servers, DPM chaining, or
Cyclic protection. Here is a breakdown of each:
Primary to secondary protection: The database and replicas stored on a primary DPM server can be backed up to a secondary DPM server. If the primary server fails the secondary server continues to back up protected workloads.
For more on Primary to secondary protection:
http://technet.microsoft.com/en-us/library/jj244598.aspx
DPM chaining: A chain of DPM servers provide protection, and each server protects the next one in in the chain. For example:
DPM1 is protected by DPM2 (DPM1 is the primary and DPM2 is the secondary).
DPM2 is protected by DPM3 (DPM2 is the primary and DPM3 is the secondary)
To setup chaining:
http://technet.microsoft.com/en-us/library/hh758194.aspx
Cyclic protection: One DPM server is backed up by another DPM server, and vice versa. So that DPM1 protects DPM2, and likewise DPM2 protects DPM1.
More on Cyclic protection:
http://technet.microsoft.com/en-us/library/jj244597.aspx#BKMK_Cyclic
I hope this adds some clarification around this.

High Available SRW2024

I trying to create a high available setup using two SRW 2024 switches and Linux bonded network adapter in mode 1. Each network adapter of the bond is connected to a switch and in case of failure of an adapter or switch, the bonded network adapter will fail over to the other switch using the same MAC address.
I have an aggregated link setup between the two switches. Furthermore I have spanning tree enabled on both switches. If I do a fail-over test and the bond fails over to the other switch, the port state of the aggregated link changes to blocking which blocks all traffic between the two switches.
In case I use a single (none aggregated) link I’m able to prevent the blocking by disabling spanning tree on the inter switch port. In this case the switch needs about 10 seconds to learn the new port of the MAC address. However I’m not able to make this work on an aggregated link. The UI does have the option to disable spanning tree on the aggregated port, but when saving spanning tree is still enabled.
Questions:
1. What is the recommended setup concerning inter switch aggregated links and spanning tree configuration for above mentioned high availability configuration.
2. Why is it not possible to disable spanning tree on aggregated links? Is this by design or is there some problem with the UI?
Any help appreciated.

I have rapid spanning tree enabled on both switches.
The problem is that I have to disabled spanning tree on the link connecting the two switches together. If not the inter switch link will be blocked the moment I fail over the network bond because it probably thinks there is a redundant path. Is there some other way to prevent the inter switch link from blocking?
If not, how can I disable spanning tree on the aggregated link? So far I only managed to do this on a normal link, but cannot do it on an aggregated link.

App-V Streaming in SCCM 2012 - High Availability Possible?

Hello All,
Background:
I'm in the process of designing an SCCM 2012 R2 environment, and one of the things that needs planning for is App-V.
Currently the client uses App-V 4.5 management servers with a mixture of 4.5 and 4.6 apps so I've been told. There are 2 servers and they are load balanced, I think the SQL server used is clustered. I need to bring this App-V environment into SCCM 2012 R2,
and as such I am concerned about High availability. (I'm also aware of compatibility of app v packages but this is beside the point)
SCCM will manage around 7000 workstations, and up to 20,000 users all in all (obviously not at once). The majority of users use any machine, they do not have dedicated ones. The hierarchy will consist of one standalone primary site with SQL on box and I will
be configuring multiple distribution points and management points.
Question:
It is my understanding that Management Points cache policies, and distribution points obviously have all the data cached so to speak. Therefore, if a user is already assigned to a group which is assigned to particular streamed applications - if connection was
lost to the site database server, and they logged onto a new machine, would they still be able to run those streamed applications? Or would the Site database going down break this?
Thanks
Stefan

Yeah that's a good point Torsten, Thanks - this is what I was unclear on and wanted clarification on. Was happy with the answer but thinking about it now you have said that, I dont see how that can work either...
If im getting it right now, it would be ok if someone has already logged onto the machine, as the profile would have already been populated with the virtual application information pulled down after the client had run the evaluation and MP had retreived
the information from the site DB when it was previously online - in that case the application would still work (and be visible) as the client has previoulsy known about it and clicking it can still stream it from the DB.
But in the case of a new login, are we saying that the MP does not cache policies to the extent that it would know that user would be assigned a particular application - it would have to go back to the site DB for this information - which would be unavaliable
and therefore would break it?

UCCX 7.0 High Availability IP Addressing

Hi,
I am installing UCCX in HA mode. The servers are on the same site and have a RTT of less than 2 ms.
I am wondering whether to put them in the same VLAN or in separate VLANs. The design guide does not seem to state a preference.
Please let me know what approach works for you

Hello James,
As you mention HA over IP WAN its just support under UCCX 8.0, for now UCCX 7.0 does not support these. That infomation can be check in the SRND.
http://www.cisco.com/en/US/docs/voice_ip_comm/cust_contact/contact_center/crs/express_7_0/design/guide/uccx70srnd.pdf
Page 66 says:
"Cisco Unified CCX high availability requires that the Cisco Unified CCX Engine and Database components and the CTI Managers with which the Cisco Unified CCX servers communicate be located in the same campus LAN and that the maximum round-trip delay between these servers be less than 2 ms"
