I was recently given an old HP MediaSmart EX470 server along with some other junk hardware. Although it has no graphics, a slow single-core AMD Sempron CPU, and just 512 MB of RAM, I was able to revive it quite satisfactorily. Here’s how I upgraded the hardware and software.
Hard disk drives encounter errors from time to time, so it’s a good thing that most have the ability to recover data anyway. But RAID systems usually have their own error recovery capabilities and can be thrown off when a hard disk pauses I/O. So it’s a good idea to use hard disk drives that allow you to disable or limit error recovery in RAID systems.
Long-time readers of my blog know of my love for Drobo, but the time has come to say goodbye. My old Drobos (and Iomega ix-4) are showing their age and I decided to go in a different direction: I’m building a FreeNAS server. In this article I’ll talk about my thinking behind this move; later posts will talk in more detail about the hardware and software setup.
