Quanta MESOS CB220

The Quanta MESOS CB220 is in a 2U chassis with twelve forward facing 3.5" HDD drive sleds.

An information LED on each side shows the states of each node, and there is also an embedded power button.

The drive sleds fit perfect in each slot. The sleds use the bottom mounting points on drives; both 2.5" and 3.5" form factors are supported.

The two systems inside the server chassis share a pair of failover power supplies mounted in-between the two nodes.

On the back of the nodes we found the SAS expansion slot, a pair of USB 2.0 ports, a serial port, VGA port, three gigabit Ethernet ports (one for management), and a pair is 10GbE SFP+ ports. The second node is identical, as you can see in the image.

 

Each node also has an unlocking lever and handle, so you can slide the entire node out for service.

Here we get a closer look at the redundant power supplies. Each PSU has an exhaust fan, lever, and handle for extraction.

Each PSU has a maximum output of 1023w at 110-120v (1100w at 200-240v).

The nodes are almost like a work of art. A team of designers and engineers fits a full server in each section - twice the components of a powerful notebook in roughly the same PCB space.

Looking through the back, see wee the eight DRAM slots for the front-most CPU. The three connectors (two at the top and one at the bottom) plug into the HDD backplane. These are the only connectors for the node attached inside the enclosure.

Each node has two 2.5" mechanical HDDs in RAID 1 for the operating system, two LGA2011 Xeons, and sixteen DDR3 DRAM slots. Two 10GbE SFP+ ports come from a mezzanine card, and a LSI 9271-8i with Syncro technology populates a PCIe slot.

The CPU and DRAM are covered with a shroud to reduce the volume of air the fans need to push to keep the components cool.

A heat sink on the top of the LSI 9271-8i Syncro card keeps the LSI controller cool.

Last, but not least in our look around the Quanta Cluster-in-a-Box CB220 is a HDD layout sticker on the top of the system, so you can easily see the drive layout.
