Dell’s C6220 II server squeezes four Xeon E5-2600 v2 systems into 2U of rack space, essentially doubling density. It is sometimes called "Killer of 1U form factor" server ;-)
C6220 was released in April 26, 2012 and in 2013 updated for Xeon E5-2600 v2 line of Intel CPUs. It is a custom machines for very large customers who want fewer bells and whistles but higher computing density and lower power consumption. The PowerEdge C6220 is being marketed as a high-density server solution primarily targeting HPC (high-performance computing) and virtual server clusters.
It has weak onboard RAID controller (mainly for Windows, for Linux you need at least $200 additional card and only 1Gbit NIC cards on the motherboard. So it you want 10Gbit you need to put an additional card.
The C6220 offers four completely independent, hot-swappable server nodes. Each server node can be configured independently of the other nodes in the same chassis to perform specific tasks. They can have different CPUs, different amount of memory and different number of hard drive, providing better flexibility in respect to harddrives that 1U servers. The chassis also accepts a pair of dual-height nodes which have two PCI-e expansion slots.
The four nodes are accessed at the rear where each one provides dual Gigabit ports (not 10GBit), IPMI, two USB2 port, VGA and a serial port.C6220 allow to use CPUs consuming up to 135W. This means the entire range of E5-2600 and v2 CPUs is supported.
Expand your I/O bandwidth and enhance the capabilities of any PowerEdge C6220 II configuration with PCIe 3.0-capable slots.
C6220 II can be used in various high-workload-intensive environments.
Remote management is done differently then in standard Dell servers -- not via DRAC but via so called Baseboard Management Controller (BMC), which is a microcontroller located on the server’s system board. BMC provides the “intelligence” within the IPMI architecture, responsible for monitoring and controlling the server’s manageable devices. Capabilities are very similar to DRAC but organized in diferent menus. It also has Java console. Among features:
Out-of-band monitoring and control for server management over LAN
Dedicated NIC for remote management via network
FRU information report, which includes system board part number, product name, and manufacturer.
Health status/hardware monitoring report
View and clear events log
Event notification by lighting chassis LED indicator and Platform Event Trap (PET)
Platform Event Filtering (PEF) to take selected action for selected events
Chassis management, which includes power control, status report, front
panel buttons, and LEDs control
Drives are installed in enclusure not in sled. Up to 12 x 3.5" or 24 x 2.5" hot-swappable SAS, SATA or SSD drives are supported. Thar means 48TB SATA and 48TB SAS maximum storage per chassis.
You can allocate different number of harddrives to each node if you use 2.5" expander backplane:

I am in the process of upgrading the firmware on some of our C6220 systems using the ipmiflash utility. I have several systems that have hung during the "Validating Image" in that it will never exit that stage of the flash. I can kill the update script but leaves the ipmi interface in "update mode". The only way I know how to get it out of this sate it to reseat the sled in the chassis to reboot the ipmi controller as in this state the ipmi controller ignores any reset commands (which is the correct action to prevent bad stuff during the actually flash). Is there a raw ipmi command I can send to get it out of the "update mode"? Adam Hough Senior Computer Systems Engineer, NSA Global Compute Resources
Two things about this -
1) for convenience I use ipmiflash on all my test systems. but at scale I use socflash only, because it does raw reads/writes to the flash rom. It never fails. However, socflash defaults the MAC address of the BMC, which you have to put back. So the procedure is to capture those macs, socflash the bmc, put them back. "bmc" tool has a convenience function you can use to facilitate this; you have to run this locally on the box. From memory:
bmc get_both_macs | tee /tmp/mymacs
# Be sure to confirm that every /tmp/mymacs file looks right / has macs in it. I've recently seen occasionally that this would fail. (Fix forthcoming)
# Apply a new image; skip image backup step; use the "all*.bin" file when you flash with socflash
socflash_x64 -s allXXXXX.bin
bmc set_both_macs /tmp/mymacs
Note - this wipes all bmc settings including which NIC it uses; so you go back to shared/DHCP.
2) Because of how it works, socflash can also be used to hard reset and/or revive a hung (or even completely dead) BMC. This resets the BMC as a side effect of reading the image and throwing it away. There are very, very few situations where this will not work:
# Hard reset a BMC
The user friendly version of that is to get "peclogs" from http://poweredgec.dell.com and run the command line option to reset the bmc (I forget what it's named).
Be careful with socflash. It's powerful, but it has quirks and basically no safeties.

Dell - Internal Use - Confidential Good morning Adam To add to Michael's information The reset syntax that I have for socflash is socflash option=r of=/dev/null As Michael pointed out, this functionality is built into the pec-logs utility as well, the syntax is pec-logs.sh --bmc-reset Josh Moore
Dell c6220 IPMI controller odditites"
The networking configuration of the IPMI controllers on our new Dell c6220 boxes is strange to say the least. We've encountered issues where the IPMI controller binds to a random interface, usually making itself inaccessible to the world.
I've done some digging into this, and it seems that the IPMI controller is really an embedded Linux device (no surprise there). It has two main network interfaces:
- bond0 – This is used for the "shared" network option of the IPMI controller. As far as I can tell this bond is created in active-backup mode. This means that if your primary network interface drops for any reason, the IPMI controller will failover to the secondary network interface. The only way to get it to fail back over to the primary network interface is to briefly down the secondary network interface. Resetting the BMC will have no effect (which is dumb).
- eth1 – This is used for the "dedicated" network option. If you're using this, you should definitely configure the IPMI controller to use it, and don't just rely on it's auto-detection of this.
Speaking of configuring the network mode, you have two options for this '1' or '2'. The documentation doesn't indicate which is which, but based on my testing '1' is shared networking, and '2' is dedicated networking. Seems silly they couldn't manage to put descriptions in for this.
