Should You Consolidate Your Servers Onto Oracle SuperCluster?

"Are you planning to consolidate a server running a business-critical application that you want to update with future releases over upcoming years, or are you trying to get rid of an old server running a legacy application that will not be updated anymore?"

This is just one of the questions Thierry asks in his article, which is a great resource for sysadmins, systems architects, and IT managers who are trying to decide whether to consolidate individual servers onto an Oracle SuperCluster. Your answer will determine whether you should put your application in native or non-native Oracle Solaris zone.

Other questions Thierry and friends ask:

  • Is my server eligible for physical-to-virtual (P2V) migration?
  • Are you planning a long-term or short-term migration?
  • How critical are performance and manageability?

Once he has helped you determine your general direction, he discusses these architectural considerations:

  • SuperCluster domains
  • Network setup
  • VLAN setup
  • Licensing considerations

Finally, he provides a thorough step-by-step instructions for the migration itself, which consists of:

  • Performing a sanity check on the source server
  • Creating a FLAR image of the source system
  • Creating a ZFS pool for the zone
  • Creating and booting the zone
  • Performance tuning

And just in case you're still not sure how it's done, he concludes with an example that shows you how to consolidate an Oracle Solaris 8 Server Running Oracle Database 10g. It's all here, give it a good read:

Best practices and hands-on instructions for using Oracle Solaris Zones to consolidate existing physical servers and their applications onto Oracle SuperCluster using the P2V migration process, including a step-by-step example of how to consolidate an Oracle Solaris 8 server running Oracle Database 10g.

Allan Packer, Lead Engineer of the Oracle SuperCluster architecture team, as explains how the design of this engineered system supports consolidation, multi-tenancy, and other objectives popular with customers.

By the way, that's a picture of an 01 Ducati 748 that I took in the Fall of 2012.

The Impact of Oracle Optimized Solutions on a Sysadmin's Job

When Oracle acquired Sun we kept it simple. In doing so we came up with Oracle Optimized Solutions. Of course they're great for business because they are assembled from a pre-configured stack of Oracle products that we test and use ourselves, but are they be great for Sysadmins? I decided to ask.

The best person to ask anything about Oracle Optimized Solutions is Marshall Choy. Not only is Marshal the director of the engineering group that selects and assembles these systems, but he began his high tech career as a sysadmin working on both Solaris and Linux systems. Marshall agreed to let us put him on the spot, so Justin interviewed him on OTN TechCast. In addition to talking about a sysadmin's job, Marshall explains the patching strategy for these types of stacks. Here are some of the questions we asked him.

  1. What's the difference between Oracle Optimized Solutions and Oracle Engineered Systems?
  2. What will this mean my job as a sysadmin - will my skills become obsolete? Will I be replaced by someone less skilled?
  3. I'm not sure I want to outsource my sysadmin skills to Oracle - how will these optimized solutions change what I spend my time doing?
  4. Aren't we just turning back the clock 20 years - why did you decide to build a proprietary vertical stack?
  5. What if I want to change something in the stack, how will it affect my support contract?
  6. How often do you update the components in the stack, and do I get those updates for free?
  7. How do I install updates and patches?

It's a good show. It lasts 14 minutes. Don't miss it.
