Use proxy_intercept_errors and proxy 500s to a server that has caching enabled.

Seems a duplicate of this: http://stackoverflow.com/questions/16756271/how-to-configure-nginx-to-serve-cached-content-only-when-backend-is-down-5xx-re In short, use proxy_cache_use_stale As an update, i tested this and it works fine. I did the test in my workstation where i have (for completeness): Fedora 23 nginx 1.8.1 configured as ssl terminator + ...

The two NICs in the R610s are totally separate... So, if one goes bad, the other one will continue to function. Now, to answer your specific question: No, the Broadcom controller chips do not provide fail-over redundancy. Having the multiple NICs does allow for that functionality though. You will simply need to configure a NIC Team. A NIC Team is a logical ...

This image represents an entry level amount of redundancy that can be achieved network wide. Switch 1 and Switch 2 represent a collapsed Core/Distribution network and Switch 3, 4, and 5 represent an access network. Switches 1 and 2 should usually be aggregated by combining them into some kind of stack when possible, however you can configure them as 2 ...

You will need the multiple NICs in each box and the two switches, with each box plugged into both switches. Then setup NIC Teaming/NIC Bonding. For most modern operating systems it is a pretty simple setup, and in most basic environments it will just work. In Windows Server 2012 you have to use Switch Independent mode and the OS will take care of ...

Very interesting question. The more I think of an answer to this problem them more road blocks I am hitting. Here is a few possible solutions that I can think of: Two NICs in Each Machine + Two Switches This is obviously what you suggested but you might run into problems with each computer on your network taking 2 IP address's. What I would suggest for ...

This could be a permissions issue on your AD. The user who is creating the cluster, or in your case running the validation wizard, must be able to create computer objects/accounts in AD. I would first check that. When running the Failover Cluster Wizards an computer name object (CNO) is created for the cluster, if this fails, you may experience the error ...

I'm gathering you're looking to roll both high availability and some kind of load-balancing into one system. There is only really one way you can kind of achieve something like this with a SQL Server 2014 Availability Group and it isn't exactly what you noted: Readable Secondary Replica https://msdn.microsoft.com/en-AU/library/ff878253.aspx The ...

As Murisonic comments, there is no definitive answer to this, all I can say is that the DHCP role is supported on a DC. On the plus side less VM's less overhead, possible slight performance because DNS and DHCP are on the same servers. I can't really think of any downsides so I would go ahead. Also have a look at the IP address Management (IPAM) role for ...

If my understanding is correct mirroring phase begin using restore database with norecovery option. So you should restore database with recovery

It's a bit late to answer this question now. Nevertheless, I came across this issue past week and couldn't find the answer in the context of "repmgr". pg_ctl resides in the bin directory of your Postgres installation. The bin directory is not in the PATH environment variable. You can not set the environment variable either which makes this problem a tricky ...

2008R2 doesn't support shared VHD's. Some alternatives: Use a share witness instead. Install Microsoft iSCSI Target on the host and connect a VHD to that. Then use the iSCSI Initiator inside the VM to connect to the iSCSI Target.

In HyperV 2008 R2 you need to use an iSCSI disk as your shared storage. This is configured in the guests same as you would a physical machine, not in Hyper-V. Hyper-V on Server 2012 allows you to use a shared vhdx instead. If you don't already have iSCSI storage available you might want to look at upgrading to get that new feature.

Thanks to gf_ for suggesting Linux Virtual Server Project, their Virtual server via NAT is exactly what I needed. Thanks to all for your contribution
