Server Architecture Layout - Advice Needed! RRS feed

  • Question

  • Hi all,

    I have a few concerns over redundancy in my network. Please give advice on the possible scenarios and solutions.

    What happens if:

    Operating Systems: Server 1 (2008 R2), Server 2,3,4 (2012 Standard)

    1 - Server 1 crashes. This has actually happened before. The O/S was so corrupted I had to do an in place upgrade refresh the system files. The data was sitting on another partition so the data was unharmed. This server backs up the critical data to Server 2 every night. For the time being though, I had to manually give employees their files by attaching the .vhd file (given from backup) to the storage manager in server 2, then I could access the files. Also during this outage, there was no printer access, so i'm thinking about printer redundancy.

    But i'm wondering if the following would work as a future solution. If it happened again, attach the .vhd file and share it out (the permissions should be retained). I would plug in another ethernet cable to it's second NIC and make it the same IP as server 1 (which is now offline). OR i could change the DNS entry to just point to server 2 IP. I would also then have to install the print server quickly along with drivers, etc. Would this work?

    2 - Server 2 Crashes. Not much happens since it's not "mission critical", it just houses backups and that's it for now.

    3 - Server 3 & 4 crash. These are set in a fail-over state for DHCP/AD/DNS/DC. IF they both crashed, no one would be able to login. Would it be possible to either quickly make Server 1 or 2 a DC?? How would I go about this? Would you recommend doing it now?

    I've also researched a bit into creating a server 2008R2 on-demand instance on an EC2 Amazon Web Service Instance, getting the data over there, and then spinning it up if server 1 were to crash. I'd have to setup some kind of site-to-site VPN though?

    Any possible flaws seen in this system?? Any suggestions/advice?

    Thanks!

  • You can configure multiple print servers. But ensure the print service on the fail over servers which is hosting the printers to be stopped. once the primary server fails then you can re-direct the print service to the other server. However it will be wise to upgrade server 1 to server 2012. So you can use the SMB 3.0 shares and also better performance and management for High availability.
