This is very interesting, my situation is as follows I do have one DS3200 controller (44W2169) SAS (without daughterboard) working fine; one DS3300 controller (44W2170) with broken iSCSI daughterboard. Both have mainboards equipped with 2 SAS ports, one for expansion unit and the other for...

I found a workaround and turned off Hyper-Threading. Now all tests are ok. It would be great to find a real solution.

It should, from the manual: "The X9DR3-F/X9DRi-F motherboard supports up to 1 TB of Load Reduced (LRDIMM), 512 GB of Registered (RDIMM) or 128 GB of Unbuffered (UDIMM) ECC/Non-ECC DDR3 800/1066/1333/1600/1866 MHz 240-pin 4-channel memory modules in 16 DIMM slots." Server boards mostly do...

hi there, I have Supermicro X9DRi-F dual LGA2011 mobo and two pairs of CPUs. Two E5-2630v2 and two E5-2667v2. When running E5-2630v2 (single/dual) everything runs nice and smooth. When running E5-2667v2 single everything is ok too. This applies to both CPUs. When running E5-2667v2 dual I get...

Hi there, The only hardware difference I was able to find between IBM 44W2169 (SAS based for DS3200) and 44W170 (iSCSI, DS3300) raid controllers are the daughterboards. So my idea is to crossflash 44W170 to 44W2169 and remove the daughterboard (to get second 44W2169). Has anyone tried this...

Hi there, I need interposes for IBM DS3200 and I don't want to spend too much. Can I use ones manufactured by Dell, for example? Or it's IBM (PN: 40K6882) only?

Solved, firewall problem

Hi there, I'm trying to mount iscsi share exported from old IBM DS3300. I'm using Debian Bookworm 6.1.0-21-amd64. Unfortunately, after iscsiadm -m node -T iqn.xxxxxxxxx -p 192.168.1.236:3260 -l I get the following error: ping timeout of 5 secs expired, recv timeout 5, last rx 4405941922, last...

Hi there, I have a stupid question, maybe very stupid. If I'm not wrong, IBM 46M0997 and Lenovo 03X3834 use the same chipset. Did someone try to crossflash between IBM 46M0997 and Lenovo 03X3834 (any direction)? What would be potential benefits?

I'm trying to setup NFS over RDMA using two QLE7340 InfiniBand HCA directly connected. IPoIB works fine and I'm able to mount using: # mount -t nfs 1.1.1.1:/tmp /mnt/tmp Unfortunately, mounting over RDMA gives error: # mount -t nfs -o proto=rdma,port=20049 1.1.1.1:/tmp /mnt/tmp mount.nfs: an...

OpenSM errors were caused by missing software. It seems that QLE7340 needs iwpmd daemon (present in Debian rdma-core package).

AOC 40G 850nm AQOA9N13ADLN0723 Seems incompatible with QLE7340. Woks only at width 1.

I bought following SAS cables: 038-003-699 EMC 3GB/S QSFP CABLE 1.73M NETAPP 112-00176 40cm Both work stable at QDR/40Gbps. In case of short passive DAC cables it is possible to get much higher bitrate that specified.

Answering to myself

I use QLE7340 which are IB only
