Elasticity: The Biggest Challenge Facing Today's Data Center

Biggest Challenge Facing Data Centers Today

Interview with Brian Bream, Collier IT

Provisioning used to be a hardware activity. It involved heavy lifting. Today, thanks to Oracle's engineered systems, a data center can pre-configure itself to make provisioning a software activity. According to Brian Bream, CTO of Collier IT, instead of pulling a server off the shelf, installing an OS, and applications, then patching and configuring, it's a matter of bringing up the management tool, selecting the image, and hitting Bang! In Brian's experience, elasticity is the biggest challenge facing data centers today, and Oracle engineered systems are a great way to deal with it.

In addition to being Collier IT's Chief Technology Officer, Brian was named instructor of the year not once, but twice, by Oracle University. Get his opinion about the impact of training on the careers of sysadmins.

Live Video Interviews on OTN Central at Oracle OpenWorld 2013

Good thing I drove to Oracle OpenWorld this year instead of riding the moto like I have on some previous OOW's. We had an inch of slush on Donner pass, and if we hadn't skeedaddled outta there when we did, we might have wound up like the ATV in my driveway in Colorado.

This year Oracle wants its customers to talk about their experiences with Oracle technologies, so OTN has lined up three live interviews. If you're at Oracle OpenWorld, you can watch them on the big screens. If you're not at the event, you can still watch them live from our home page at www.oracle.com. If you want to watch them later, look for a future blog in which I'll post the location of the recorded interviews.

Monday, 12:00 noon PT - John Dome, Systems Engineering Lead, Progressive Insurance

John will describe the business opportunity that lead Progressive Insurance to switch from Red Hat Linux to Oracle Linux, he'll explain why he recommended they switch, the results they got, and how it has changed the way Progressive's DBA's and SA's work together. We'll try to get as techie as we can in the time we have.

Tuesday, 11:50 am PT - Gautham Sampath, Chief Information Technologist, Pinellas County Government

Gautham (pronounced like Batman's Gotham) recently led an effort to refresh the Pinellas County hardware systems. He'll explain what they were looking for, why they chose Oracle Exalytics, how they became convinced it was the right decision, and how it changed the way they managed their data center.

Wednesday, 11:00 am PT - Brian Bream, CTO, Collier IT

Brian Bream, Chief Technology Officer of Collier IT, will describe the biggest changes data centers must deal with today, and how Collier IT recommends they face them. When we're done, he'll confess how he deals with his personal addiction to SPARC systems and the Oracle Solaris operating system.

Plus recorded videos

We're also going to have a snowsquallfull of recorded interviews, which we'll begin posting during the evenings, since going to all-night parties is getting harder and harder to recover from. Look for them on OTN Garage YouTube Channel.

Cloud Building with Oracle Solaris 11

Three resources to help you build clouds with Oracle Solaris 11

Training Class - How to Build a Private Cloud with Oracle Solaris 11

by Oracle University

This training class combines multiple enterprise level technologies to demonstrate a full cloud infrastructure deployment using SPARC technology. Learn To:

  • Plan for and deploy a private Infrastructure as a Service cloud
  • Combine various Oracle technologies into a robust cloud infrastructure
  • Practice cloud component creation and configuration tasks by performing a series of guided hands-on labs
  • Perform the critical steps associated with the configuration of cloud and related facilities.

Tech Article - How to Build a Web-Based Storage Solution Using Oracle Solaris 11.1

by Suk Kim

Have you ever wanted to build a cloud just to see if you can? Turns out it's not that difficult. Install Oracle Solaris 11.1 on your laptop via VirtualBox, set up a little ZFS storage, a little access control, and configure AjaXplorer so you and your friends can manage your files. Don't neglect to drop phrases like "Download that from the cloud I just built" into casual conversation.

Tech Article - How to Put Oracle Solaris Zones on Shared Storage for Easy Cloning

We liked this blog so much when Jeff Victor first posted it, that we turned it into a bonafide OTN tech article. You might recognize it. It's about ZOSS: zones on shared storage. Why? When you configure a zone on shared storage, you can quickly clone it on any server that uses that storage. Jeff explains how.

What Sysadmins and Netadmins Spend Their Time Doing

source

This survey covers a wealth of topics, including how the jobs of sysadmins and netadmins are changing.

A large percentage of both sysadmins and netadmins agree that their jobs are getting more complex and they are spending more time on the job performing more duties with fewer resources.

The survey includes a breakdown of what sysadmins and netadmins spend their time doing on the job, and the number of hours they typically spend on each task. But it also includes a wealth of other data about sysadmins and netadmins. Did you know that ...

75% of sysadmins have at least some influence in IT decisions, and 20% have strong influence, whereas 100% of network admins have from strong to complete decision making authority.

Interestingly enough, the amount of influence they have on IT decisions corresponds to their job satisfaction:

Network Admins find their job more enjoyable, are more satisfied, and feel more appreciated. Sysadmins are much more frustrated with many aspects of their jobs, and are more likely to see themselves in a different career in the future.

The percentage of male to female sysadmins was about the same, but more network admins were men. As you might expect, the most popular TV show among both sysadmins and netadmins was ...

OMG! What Did I Just Install?

Quick Quiz:

Q: What's in this Solaris 10 package: SUNWlibstdcxx4S?
A: You cheated. You googled it and found the link to the Oracle Solaris 10 documentation.

You're in luck, because each release of the Solaris 10 documentation contains a Package List for that release. For example:

Now try this:

Q: What's in this Solaris 11 package: compress/p7zip?
A: buzzer!

The Solaris 11 documentation does not include a package list. You can find mentions of some packages through google, but it's hit and miss. And you still don't get the rest of the info about the package that the Solaris 10 documentation included. So how do you find out what Solaris 11 packages you just installed? Here are two methods.

The pkg list Command

The pkg list command lists all the packages currently installed on your system. If you use it, redirect the output to a file so your screen doesn't wind up looking like a scene out of The Matrix. Since package naming is hierarchical, you are likely to find similar packages grouped together in the list. For example:

$ pkg list
.
.
.
compress/bzip2
compress/gzip
compress/p7zip
compress/unzip
compress/zip
.
.
.
editor/gedit
editor/nano
editor/vim

You can just list a subset of the packages you are interested in:

$ pkg list driver/network/ethernet/*

By the way, to list all packages that are available for you to install, add -a to the pkg-list command. This example asks for the name of all the packages you can install in the editor group:

$ pkg list -a editor/*

One you have a list of the packages, you can use one of the commands below to get additional info about each package.

The pkg info and pkginfo Commands

The pkg info command provides detailed information about a particular IPS package. For example:
$ pkg info p7zip
          Name: compress/p7zip
       Summary: The p7zip compression and archiving utility
   Description: P7zip is a unix port of the 7-Zip utility.  It has support for
                numerous compression algorithms, including LZMA and LZMA2, as
                well as for various archive and compression file formats,
                including 7z, xz, bzip2, gzip, tar, zip (read-write) and cab,
                cpio, deb, lzh, rar, and rpm (read-only).
      Category: System/Core
         State: Installed
     Publisher: solaris
       Version: 9.20.1
 Build Release: 5.11
        Branch: 0.175.0.0.0.2.537
Packaging Date: Wed Oct 19 09:13:22 2011
          Size: 6.73 MB
          FMRI: pkg://solaris/compress/p7zip@9.20.1,5.11-0.175.0.0.0.2.537:20111019T091322Z 

Here's another example:

$ pkg info -r solaris-large-server
          Name: group/system/solaris-large-server
       Summary: Oracle Solaris Large Server
   Description: Provides an Oracle Solaris large server environment
      Category: Meta Packages/Group Packages
         State: Not installed
     Publisher: solaris
       Version: 0.5.11
 Build Release: 5.11
        Branch: 0.175.1.0.0.9.2627
Packaging Date: Mon Feb 06 22:33:56 2012
          Size: 5.45 kB
          FMRI: pkg://solaris/group/system/solaris-large-server@0.5.11,5.11-0.175.1.0.0.9.2627:20120206T223356Z

The pkginfo command does the same for any SVR4 packages you may have installed on the same system.
