Server tour: RAM, PCI Express and Graphics

Server tour: RAM, PCI Express and Graphics


A close-up view of the 8 RAM slots.RAM sticks are installed in pairs into banks – Slots 1 & 3 make up Bank A slots 2 & 4 Bank B and so forth. These combinations are clearly visible on the main board.

As shown in this image server RAM is very similar to what you’d install in a PC – but there is subtle difference with the in-configuration. The RAMretention mechanisms however are identical to what you see on a regular PC.

Thumb-screws retain the PCI Express riser cage within the server. In most cases these can be unscrewed with your hands…

… but there are other occasions where you’ll need to use a hex key. For convenience one is supplied with all HP servers. The key for this server is mounted in a slot on top for the fan baffle that sits atop of the SAS controller.

Once the cage has been removed PCI Express expansion cards can be installed. This side of the cage allows a full-height x16 card to be installed.

The other side of the cage allows for the installation a half-height x8 card. We’re limited to just a half-height card because full-height cards would fall foul of the RAM slots.

Adjacent to where the PCI Express cage plugs in to the main board the CMOS battery can be seen. This battery is the same CR2012 battery that you see in any PC.

Servers generally don’t require dedicated PCI Express video cards – onboard solutions more than suffice. This server features an ATi ES1000 GPU with 32MB of VRAM.

The IPMI controller within the server (HP call their IPMI implementation “Integrated Lights Outâ€). As long as the server has power this controller is active and can be used to manage the server – even when it is switched off.
