Another server upgrade – Part 2

And here comes magical day – Friday, May 20th. All planning is done, hopefully, and we are ready for servers’ upgrade, update and reconfiguration.

So first let’s see what we have, then we’ll see what we want, and then we will see what we get…

Our current setup is:

3 XServes and one VMWare OS X Server all working very hard and therefore one XServe, which acts as Open Directory Master (ODM), AFP, SMB, DNS, DHCP and Netboot server, works very hard every day and hangs ocasionally. During those ‘hangs’ “hard reset” is required, which does the number on the server. Single sign-on process is not working anymore and every time server ‘hangs’, since it’s running DHCP and DNS services, none of the users can access Internet. So back to set-up:

  • XServe 1 – Mac OS X 10.5 Server, AFP, DNS, DHCP, SMB, ODM
  • XServe 2 – Mac OS X 10.4 Server, AFP, FTP, Mail, Web and FileMaker Server
  • XServe 3 – Mac OS X 10.5 Server, AFP, ODR (Open Directory Replica)
  • VMWare Server – Mac OS X 10.5 Server,AFP, FileMaker Server

Now in order to free up XServe 1 and ensure it’s stability and no-impact on Internet, I’m bringing MacMini into the picture, running 10.6 OS X Server which will be DNS, DHCP and ODM. XServe 1 would then be AFP, SMB server – file server.

Plus, all servers, except VMWare server, will be running 10.6 Server software to increase performance of existing hardware and utilize latest Mac technologies.

Another server upgrade – Part 1

There comes time, when Apple releases new OS X Server version and existing server is acting up. And that time is perfect for spring cleaning, updates and upgrades.

So this time came. Apple has OS X 10.6 Snow Leopard Server for quite some time now, with bunch of possible bugs and kinks worked out, with skinnier footprint and increased performance on existing hardware. Our existing server, which hosts DNS, DHCP acts as Open Directory Master and on top of that serves files via AFP and SMB, after multiple “hard resets” is not performing how it once did. It also, for some reasons, lost it’s “single sign-on” capabilities via AFP (while it’s OD Replica works just fine). And, on top of that all, time showed that having DHCP and DNS on the server that every now and then “freezes” and requires “hard reset” is not a practical idea – once server is “hung”, users cannot access network at all.
