Best practice configuration for SQL 2014 to achieve HA when hosted on Hyper-V 2012R2 cluster

Hi,
I've had a hunt around but so far I've not found a conclusive answer to my question.  I am currently moving from a SQL 2008R2 (physical tin) failover cluster to a virtual environment build on Hyper-V 2012R2.  I am building everything with SQL 2014
SP1.
I want to achieve the same level of high availability that I currently have and at the same time make sure that I can replicate (DR) data offsite (Azure) in the future.  I have two options with SQL which are clustered instance (basically the same as
I have now) or AlwaysOn Availability Groups for database level HA. 
I am unsure which is the best method to use when the SQL nodes are highly available guests on Hyper-V, trying to imagine how the guests will all move around in the case of a host server failure is a bit mind boggling to say the least.
I am leaning towards a instance failover but I would appreciate any input/advice etc.
Thanks
Rob

Hi Rob, 
To start with I will not be installing SQL Server 2014 with SP1, as SP1 has bugs and Microsoft has disabled its download. See reference: http://www.eweek.com/database/microsoft-halts-sql-server-2014-sp1-downloads.html
With regards, I would go for AlwaysOn Availability Groups configuration, because it has several benefits:
You will get same amount of high availability you normally get with native cluster configuration, if you use AlwaysOn configuration. However, AlwaysOn configuration provides more granular high availability, and fail-over are invisible to the application,
if you using Availability Group listener to connect to server. 
You can offload read-only workloads to secondary replica.
You can perform transaction log backups on secondary replica.
Reduce production downtime during patching or other planned work on the server.
So in short, you should use AlwaysOn configuration.

  • Airport Extreme best practice configuration for Sleep Proxy, DHCP/NAT and PPPOE

    Hi
    I have recently bought a Airport Extreme and it is working well.  One of the reasons I bought is to take advantage of the Bonjour Sleep Proxy on it so I can wake my MAC up remotely from my iPad using the REMOTE app to stream things like iTunes etc...  I followed the set up instructions and basically let it configure itself.  I have an ISP router / modem which currently is providing DHCP services, NAT and PPPOE.
    The Airport detected all of this and set itself up as bridge only.  The speed of the network outo to the internet is fine (more or less what it was before).  However, in doing a bit of research, I have found out that if I want the Airport to act as a sleep proxy, I need it to "host" the network.  I am not an expert in networking but from what I understand I need the Airport to be moved from "Bridge Only" to at least be providing DHCP to my internal network clients.
    This has prompted me to ask what is "Best practice" when it comes to configuring the Airport given I want to have Sleep Proxy enabled.  I think the two options I have are as follows but would really welcome feedback on which is the best option to go for or if there are other options I should be thinking of
    (1)  Have the Airport perform DHCP for my internal clients and leave the ISP router/modem doing NAT
    (2)  Have the Airport perform DHCP and NAT.  I think to do this I need to turn the ISP router / modem into Bridge mode only.  (I've looked and I seem to have this option on the device.  It's an Irish ISP branded device but I think it is a Zyxel)
    I have no reason to believe the ISP router / model is doing a bad job but given I understand the Airport Extreme is a reasonably high-end device (I think?) I am wondering if option 2 is the way to go.
    In addition, during my research, I have also discovered that many people seem to have their Airport Extreme also handle PPPOE.  This is currently being done by my ISP router/modem.  I am  inclined to leave it this way (following the mantra if it isn't broken, don't fix it) but if there was a good reason to have the Aiport do this, perhaps I should make the switch?  Having said this, I have seen on this forum and others, some posts about problems with Internet connection drops when the Airport is handling PPPOE.
    So, a bit of a long post, but if anyone has any information or perspective on this, I'd very much appreciate it. 
    Thanks
    Dave

    I forgot to thank you, John Galt. Yap, it solve my problem by restoring back the original firmware to 7.6.1. My unit is Airport Extreme 2012. I am still using double NAT because I cannot figure it out on how to set DHCP only in the Network tab.
    My goal it to use the airport extreme to the internet and to share the internet to all my devices in the house. Just like my previous Accesspoints. Before I use AP+router Linksy$ WRT54G and D-l!nk DIR-655 without activating the NAT to share my internet connection and they work.
    My problem is that when I set it to DHCP in the internet tab and DHCP in the Network tab in Airport Utility inorder to solve the double NAT situation, only one of all my devices (wired or wireless) can connect to the internet. Each time I connect the other device(s) to the internet my subscriber will verify my subscription (web browser based verification) in which I have to manually enter my account number, etc to validate my subscription.
    So I stick to double NAT so that I can share the internet
    Our broadband provider uses DHCP to link us to the internet. If I change the settings to Static in the Internet Tab, my broadband provider will not let me connect to the internet. In the Airport Utility if I set to static in the Internet Tab inorder to set it to solve the double NAT, a message box appear informing me that I have invalid beginning IP address in the DCHP range in the Network Tab when it appears that only the last 3 digits of the DHCP range is editable.
    Is there any way of configuring the Airport Utility's Internet TAB to DHCP and Network TAB to DHCP to connect to the internet with all my devices without the double NAT and without the aid of another device such as AP or router or switch connected to the Airport or vice versa?

    Hi Team,
    Could you please send if you have any  Best Practice document for configuring Service Parameters on CUCM 9.1.1. That would really help.
    Thanks,

    Hi
    There's no 'best practice' as such, but there are a few that I think should be default:
    Enabling CDR, On-Hook Pickup, CFwdAll Override... but really the settings are specific to the requirements of the deployment.

  • Best Practice: Configuring Windows Azure Management Services

    I have a 3 Websites, 1 Blob Storage, and 1 SQL Server that I would like to configure for basic stability and performance monitoring. I know I can set up alerts through Management Services based on various metrics. My question is, can someone give me a recommended
    set of metrics that are good baselines?
    It is nice that Azure is so customizable, but frankly I have no idea how much CPU Time in milliseconds over a given evaluation window is appropriate. Or how many Http Server Errors? More than 0 seems bad, no? Wouldn't I want to know of any/all errors?
    So if anyone has some "best practice" metrics for me, that would be really helpful.
    Thanks.

    Hi,
      >> can someone give me a recommended set of metrics that are good baselines?
    Actually, many metrics depend on your scenario. For instance, if there're a lot of concurrent requests or if a single request is expected to take some heavy computation, then it is expected to have a high CPU usage, thus it is difficult to give
    you a specific number.
    In general, you may want the CPU usage of a web server to be as high as possible (idle CPU costs money but does not provide valuable results), but if it is low enough, if additional concurrent requests are received, they can be served without too much
    delay. In Windows Azure, you may want to setup auto scaling so that if CPU usage is high enough during a period, you create a new instance. If CPU usage is low enough during a period, you remove an instance. You may also want to use response time in addition
    to CPU to monitor whether you need to add/remove an instance.
      >> Or how many Http Server Errors? More than 0 seems bad, no? Wouldn't I want to know of any/all errors?
    As for server error, in general you want to get notified by all errors (> 0), however they're unexpected and need to be investigated. But if in your scenario you expect a certain level of server errors, then it is fine to use a larger number.

  • Best practice guide for Batch Load utility in Oracle UCM.

    Hi,
    Is there any best practice guide for Oracle UCM Batch Loader utility.
    We are looking for information regarding batch size in terms of number and size of contents. Also is there any loading time standards considering the contents are uploaded in filesystem where filestore provider is configured?
    Thanks,
    Krishnendu

    Hi ,
    There are no specific set of steps / practices for batch loading contents to ucm . It would be very much dependent on how many contents does the user have to load to UCM and how well the server is configured in terms of performance .
    You can get more details from the following documentation link : http://docs.oracle.com/cd/E21043_01/doc.1111/e10792/c02_settings009.htm

  • Where does one find the Oracle Best Practice/recommendations for how to DR

    What is the Oracle Best Practice for install/deployment and configuration of ODI 11g for Disaster Recovery?
    We have a project that is using Oracle ODI 11g (11.1.1.5).
    We have configured all the other Oracle FMW components as per the Oracle DR EDG guides. Basically using the Host ip name/aliasing concept to ‘trick’ the secondary site into thinking
    it is primary and continue working with minimal (or no) manual reconfiguration. But will this work for ODI? The FMW DR guide has sections for SOA, WebCenter and IdM, but nothing for ODI.
    Since ODI stores so much configuration information in the Master Repository..when this DB gets ‘data guarded’ to the secondary site and promoted to Primary…ODI will still think it is at the ‘other’ site. Will this break the actual agents running the scenarios?
    Where does one find the Oracle Best Practice/recommendations for how to DR ODI properly?
    We are looking for a solution that will allow a graceful switchover/failover with minimal manual re-configuration.

  • Best practice document for ACE30

    Can someone point me to a best practice document for the ACE30.  I am specifically looking at best practices as they relate to resouce allocation, logging, FT, and snmp.  I am migrating from CSM so the VIP/Server configuration is basically set.  I am looking for areas that pertain to the ACE as a whole.
    Thank you

    Good afternoon,
    I'm afraid there isn't a best practices document as such, however, I would suggest you to have a look at the ACE section in doc-wiki (http://docwiki.cisco.com/wiki/Cisco_Application_Control_Engine_%28ACE%29_Troubleshooting_Guide).
    This document can give you some useful insights on different topics, including (but not limited to) resource allocation.

  • PX Best Practice doc for vSphere?

    Is there a best practice doc for utilizing the PX devices in a vSphere environment?  Specifically I'm interested in 'Boot from SAN' for two vSphere 5.1 Host servers (RD630's) dual switch iSCSI connected to a PX12-450.
    If no Best Practice then perhaps a Config doc?
    Thanks

    Hi neilchapman,
    I am not too familiar with vSphere personally or how to boot from SAN, but as far as I know you create the iSCSI LUN on the NAS device and use vSphere to connect to the LUN. Do you need help with setting up the iSCSI LUN or with configuring vSphere? If you need assistance with vSphere, you might want to contact VMware support: http://www.vmware.com/support/vsphere/

    the maximum amount of RAM your laptop can take is 3.3GB. So while you can physically insert 4GB of RAM, OS X will only be able to see 3.3GB of it.
    But I don't know how knowledgeable that poster is who says it can utilize 3.3 GB. I do know that the full 4 GB shows up in the System Profiler on my MacBook Core 2 Duo 2.16 GHz.

  • Finally! T-SQL Reference for SQL 2014 available for download!

    With a mere delay of four month since the release, it is now possible to download the T-SQL Reference for SQL 2014 for your local copy of Books Online. Due to some reorganisations of the reference material on MSDN, the language reference was misisng from
    the initial download.
    To get the reference, you need to use Manage Help Settings, which you find the SQL 2014 program group. Select the option "Install content from online". Once all information has been loaded, scroll down to the SQL Server 2014 group and you will

    Now, SQL 2014 uses Help Viewer 1.0, which is very poor, and versions 2.0 and 2.1 which ships with VS 2012/2013 is much more pleasant to use. Thanks to SQL Server MVP Simon Sabin, you can get the SQL 2014 into Help Viewer 2.x in this way. Go to
    https://helpviewerredirector.codeplex.com/
    save the file to a directory. Open a command prompt in that directory and run "HelpViewerRedirector download". Then in Help View, go to manage settings, and select install content from disk. Browse to the folder and select the files you want to see
