New DB Servers
Our Dell PowerEdge 2950 Servers for the new DB Cluster has just arrived and I’m very excited, unpacking them. 
But before we start here a few specs:
- 2x Quad-Core Xeon E5440 2.8GHz/2x6MN CPU
- 32 GB 667 MHz RAM (8x4GB dual rank DIMMs)
- 6x 146 GB SAS (15’000 rpm) HDDs (RAID10 configuration)
- Integrated PERC 6/iR Raid Controller
- Dual Power Supply
- Dual Gigabit Ethernet
Looks Nice! Let’s see what’s inside
For the Motherboard enthusiasts, this one is for you
Quite well organized, but the interesting things are still covered… So I now open the shafts.
32 GB of RAM nicely lined up
After a few colleagues got attention to the open Hardware and a few minutes of watching so called “server porn” I lift up the Server. Time to make a front image (these six HDs are preconfigured as RAID 10):
After all, the first server now stands in our “testing room” and is ready for setup. In our case CentOS 5 will be running on it.
These servers will be our new DB-Cluster, which should improve DB performance significantly.
Experiences after the install and performance tests will follow…
Unpack porn! How great’s that!

How do you guys decide when it’s time to upgrade your dataase servers? What is the key factor?

Are you now going away from the “each-webserver-a-mysqldatabase” version of the site with these babys?!

@Ben: When they are slow! Well we do monitor a lot of metrics in Ganglia and when we see that the host gets very high load during peek time and response not well anymore it’s time to call Dell!
@ghost: Hmm, yes that’s the plan (and we do it currently on some hosts). But this has not really something to do with this new babys, they are just a replacement for our masters that get a bit old now. In the near future we will seperate the webserver from the mysql slaves, a project that’s on our todo list for ages.

[...] In may 2008, we evaluted a few server-configurations and finally decided for a Dell 2950, with which we already had good experience from the DB-Servers. [...]
