Sun Fire T2000 vs. Sun Fire V440

SunFireT2000Thanks to the diligence of my coworker Scott Maziarz we have been able to run some practical performance tests on the new Sun Fire T2000 we got on a try and buy program from Sun.

About our environment

While we’re not truly equipped for traditional load testing here at Plymouth State University I decided early on that our daily datamart scripts would be a good test of this system’s capabilities. These scripts are a combination of vendor supplied and homegrown code which create datamarts for reporting. The scripts run separately take between a minute and several hours to complete. They rely heavily on joins and functions so, while there is a fair amount of disk I/O, the speed of the processors and memory should play a large role.

Oracle 9iR2 was used for the testing on both systems. The database configuration was not altered, so despite the point that the T2000 has twice as much memory as our V440s (16GB versus 8GB) Oracle will be using the same amount of memory on both systems. We also unfortunately did not have the opportunity to do any performance tuning on the T2000. As such I consider this a comparison with a straight out of the box T2000. With some careful system tuning the T2000 would probably perform even better.

The two systems

Sun Fire T2000

  • 8 core 1.0GHz UltraSparc T1Processor
  • 16GB memory
  • 2 * 73GB 10K RPM SAS hard disk drives

Sun Fire V440

  • 4 * 1.0GHz UltraSparc IIIi
  • 8GB memory
  • 4 * 73GB 10K RPM Ultra320 SCSI hard disk drives

While these two systems are different in many ways they are comparable in price (the V440s are actually quite a bit more expensive, but this one is around two years old now.) All testing was done on internal disks making the results dependant on the entire system performance.

Oracle was not reconfigured to take advantage of the extra memory in the T2000.

The tests

For the testing we chose a set of 19 datamart creation scripts which we run daily in our production environment. To assure that there is no additional load on the V440 we ran the tests on our reporting instance which is on a relatively idle system.

The first test is to run the 19 datamart scripts staggered. This is how we run them in production. Four scripts are started every half hour to spread out the load on the server. There’s a lot of overlap, but the staggering is enough to keep the system responding normally.

Scripts running staggered

The graph above represents the runtime of each job individually. A shorter line represents a quicker runtime and we can see that the T2000 consistently outperformed the V440 often running n a quarter the time!

The total runtime for all 19 jobs was 2915 minutes on the V440 and 847 on the T2000. On average it took only 29% as long for the jobs to run on the T2000!

For the second test we ran all 19 jobs at once.

Scripts running simultaneous

We still see a significant improvement in performance, but not as high as when these were run staggered. Here the T2000 completed the tasks in 59% of the time of the V440. I attribute this to contention for disk on the T2000.

Thanks to Scott Maziarz for running the bulk of these tests and compiling the results for me.


The Sun Fire T2000 has certainly proven its worth. Some may be put off by the relatively low processor speed (the model tested was a mere 1GHz) but it is clearly not an impediment. The 8 core CPU seems to be up to the challenge and I’m sure with additional tuning I’m sure they’d scream.

With increased performance and higher efficiency than the comparably priced V440, the T2000 will definitely be in our future. The lower energy consumption and lower heat output would be a welcome change in our already taxed data center and the compact 2U size should be an easy fit in any rack.

Getting Started with the Sun Fire T2000

SunFireT2000After receiving my try-and-buy Sun Fire T2000 over a week ago it’s finally up and running. While we have yet to hit it with much of a load, here are some thoughts on the out-of-box experience:

Before even powering up there are a couple interesting observations about the system. The first is the lack of power button, switch, or key. In fact there is only one button on the system and that is an indicator button which just flashes an LED on both the front and back of the system to make it easier to locate (a nice feature, by the way.) You’ll quickly find the hot-swappable dual power supply and fan compartment. The adventurous will find and the big button on top of the system which allows you to gain access to RAM and other non-hot-swappable components.

All of these compartments and components are accessible without the need for tools. The hard drives are on hot-swappable sleds which pop out the front of the box. The hard drives are small (2.5″ I believe) allowing room for 4 bays in the front and still affording enough space for ventilation. I was somewhat surprised to find laptop-style drives in a Sun server, but I guess I can’t come up with any reason not to.

After giving the hardware a good once-over it was time to get the T2000 up and running. I have to say Sun came up a little short on the out-of-box experience at this point. I’m comfortable with, even partial to the absence of on-board video on a server, and Sun has chosen to include serial via RJ-45 on the T2000. Sun was on the right track including two cables appropriately shielded for use with this port, but neglected to include an adapter to go to the 9 pin serial we all have on the back of our PCs.

After rummaging around for the proper adapter to hook the T2000 to an old laptop we plugged it in. The system is surprisingly (read obnoxiously) loud, but hey, it’s a server not a desktop. After a few minutes of the regular hardware diagnostics stuff the system came up to an sc> prompt.

This is where those who are not familiar with Sun’s newer hardware will come to a complete stop. The only documentation included with the system is the Sun Fire T2000 Server Getting Started Guide and that does little more than tell you what the different lights mean and where you can find more documentation online. If you get online and grab the Sun Fire T2000 Server Installation Guide this will walk you through dealing with the SC serial management port. In my opinion Sun should have included this one in hard copy with the system as well.

After a couple more steps things start to feel familiar and the rest of the setup is much like the Solaris 7, 8, and 9 installs I’m used to. With just a few extra steps here you can (and I’d recommend) configure the SC Network Management port which will allow you the same functionality as the SC Serial Management port without the need for the serial cable and adapter. You will need an extra network drop and IP address to use network management, but then you’ll be able to telnet to it for administrative functions. Of course in a production environment you’d want this behind a firewall or on a private subnet.

Other than that the system seems quick. Our next step is to get Oracle on the system and throw some queries at it. I’ll share more as soon as we get some results.

UPDATE: I have now had the chance to test drive some Oracle jobs on this system. Check out my findings here.

SunFire T2000 Try and Buy

SunFireT2000After being tipped of on the Sun try-and-buy program by Alan Baker, a coworker and cohort, I figured I’d throw my hat into the ring for a chance to test drive a SunFire T2000… and today it arrived.

Here’s what Sun has to say about their program:

Toss your toughest workloads at the multithreaded Sun Fire T2000 server with the Solaris 10 Operating System, and watch it crank up your database and Web application performance.

We’re so confident in the quality and performance of the world’s first eco-responsible server, we’re offering a free 60-day trial, risk-free. If you’re not totally impressed, just send it back at our expense and owe us nothing.

Chances are that you will be dazzled by your trial server and come back for more. The new Sun Fire T2000 server will likely become your multithreaded workload energy-saving powerhouse of choice.

When you apply for the Try and Buy program you get the choice of a four, six, or eight core 1GHz UltraSPARC T1 processor. I chose the eight, not just because bigger is better, but also because it is closest to our production Oracle servers in capacity and price.

So once we can find the time we’ll get 64-bit Oracle installed on there and run it through the paces. On deck are some join, function, lookup intensive datamart creation scripts which currently crush our production server every evening. This should be fun.

Also of interest is Sun’s claim of this server being “the world’s first eco-responsible server”. While I am unlikely to bring in a kilowatt meter to verify these claims, we are a very green university and hey, everyone wants to save a few bucks on electric.

UPDATE: I have now had the chance to test drive some Oracle jobs on this system. Check out my findings here.
