Density – More than just CPUs per 42U rack?
There are many new dense (more than two sockets per RU) solutions out there, however they all fall under one the 3 groups:
- Blade - Multiple (8-32) hotswap servers in one host chassis, sharing power and io via plugin modules
- Multi Motherboard - Two or more servers sharing the same PSU and fans, but with independent io
- Half depth - Reduced form factor servers to allow more in one rack, SGI (Rackable) / Verari / IBM iDataPlex
It occurred to me that while the new designs can cram a lot in rack, they don't necessarily make for a dense data center. I decided to look at how many sockets we get per floor tile (600x600) using 42U racks. Taking into account aisles (in a hot aisle - cold aisle config) and switching but not perimeter walkways. For example here is the benchmark using 1U pizza box servers.
1U Conventional Servers
4x 42U racks housing 160 dual socket 'pizza box' server = 320 Sockets
2U in each rack set aside for switching to be fair to the blade and iDataPlex systems
7 Tile Pitch - 4 racks = 14 Tiles
22.86 Sockets per rack tile
