While the Supermicro X8DT3 CPU: 2x Xeons with 2x Intel Xeon(R) CPU E5504 @ 2.00GHz and RAM: 64GB RAM EEC Dual-Powersupply is a great mainboard with java remote web IPMI console that allows you to access the bios and remote mount CDROM.ISOs!
GREAT!
We have a more recent Siemens Server with Intel S2600CWR Mainboard and i can’t get their BMC Console Screen output working. (also Java based but could not manage to get it working)
Some sort of Java SSL problem:
# under linux you can try to generate a self signed certificate (src) openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 9999 # did not accept it: "SSL certificate validation failed.Please try to upload the certificate and key agai
You may need to first upload a SSL certificate to BMC. The steps to do that can be found at http://download.intel.com/support/motherboards/server/sb/intel_rmm4_ibwc_userguide_r2_72.pdf page 90 section 7.3.7
so this sucks about that intel board.
back to supermicro:
The only thing that sucks about it is the onboard LSI 1068e suck raid.
the linux drivers for 1068e (probably still) suck.
so what you do is disable the controller by pulling off the below circled red jumper (JPS2) and setup software raid with mdadm under linux and let linux do all the RAM harddisk access buffering (which linux does per default tries to use non-used RAM as harddisk buffer).
pull the jumper marked red (JPS2 hard to read, it is labeled below the jumper)
JBOD (abbreviated from “just a bunch of disks/drives”) is an architecture using multiple hard drives exposed as individual devices. Hard drives may be treated independently or may be combined into one or more logical volumes using a volume manager like LVM or mdadm; such volumes are usually called “spanned” or “linear | SPAN | BIG”.[2][3][4] A spanned volume provides no redundancy, so failure of a single hard drive amounts to failure of the whole logical volume.[5][6] Redundancy for resilience and/or bandwidth improvement may be provided, in software, at a higher level.

what is interesting to know:
tell my i am wrong but it seems like the LSI 1068e adapter is simply a little linux embedded PC doing mdadm software raid?
