I take an old server we had lying around, a white box that CMP bought for us several years ago, and install a crispy clean copy of Windows on it. Of course, I haven't used one of these servers in a while, so I forgot that nothing works on it without the driver disk. So I had to dig out a rarely used driver disk and get everything working. That took longer than you'd expect.
So once Windows was running correctly, I shut it down and pulled the server out to put the FC card in. I haven't used these servers for hardware, I was doing only software testing at the time they were in popular use. So I was surprised to find that, in a 1U server, all the expansion slots were straight up and down.
Swearing, I went looking for the expansion lift to turn the cards sideways. Finally, I gave up in frutstration and dug out a newer tower machine.
Ripping the tower machine apart first, I slipped the card in and started the install. Thankfully, all went well, and a short three days after starting to play with this rig, I was able to hit the disks.
The actual SAN gear installed like a dream. All of my problems were from trying to use an old machine.
