Hi; The SAS drive cage in c6145 does not have secondary channel for sas-drive. BTW, the ability of 2-channels of sas is for fault-tolerance of cables or expanders or external raid-controllers, connecting each channel to another host may require some special softwares/drivers to handle disk...

>however it requires a special HDD adapter to use them This may contains SFF carrier, i think. 625034 B21 HP SL390S SFF Enabler Kit | eBay BTW, I bought SL390s node w/o s6500 about $30; I'm happy if I can boot w/o s6500 some day:)

There is two types of motherboard for DL160G6: 511805-001 for Xeon5500 series 608882-001 for Xeon5600/5500 series please see labels on the motherboard to identify.

My drives(GB1000EAMYC) are 35-43C (max:53C) reported by ACU. WD red series max temp is 70C... I'm afraid that your hdd temps are too high.

10 drives in bays. Lower 8 Drives to P410, Upper 2 side bays are for boot-drives (direct cable), upper middle 2 bays are empty for air intake.

I'm running WCG(11 threads) on my DL180G6 w/dual X5650(no hyper-threading), fan speed 4200-4700 rpm, 63C max by coretemp. When I used 12LFF expander board, over 70C in my memory.

DL180G6 12LFF expander board uses VSC7155, that can be up to 3.0Gbps per lane. (but I'm using 8LFF board with 12LFF cage, cuz the 12LFF board covers air intake, causes high CPU temp...)

@Marsh I installed english language pack and get-vmhost | FL from powershell, it says IovSupportReasons : {The chipset on the system does not do interrupt remapping, without which S R-IOV cannot be supported., To use SR-IOV on...

I'm very sorry about VT-d (SR-IOV) capable on my DL180... get-netadaptersriov from powershell causes the following: Name : Ethenet 2 InterfaceDescription : Intel(R) 82576 Gigabit Dual Port Network Connection #2 Enabled : True SriovSupport : NoIoMmuSupport...

(PWM on FAN)=(PWM from board generated by BMC) AND (PWM signal created by NE555), not backing to DL180 board.(NE555 DIScharge signal is open collector) VT-d: I used 2012R2, SR-IOV can be checked on motherboard-LAN(82576).

(sorry for my poor english) - I've made two boards, one is for FAN1/2 and another is for FAN3/5. (SENS pins are individual) - some newer version of BMC firmware checks as if the fans are controllable by PWM, so I used a version of 4.23. - this analog method is very cheap, but I think it's more...

I used an analog method to solve this problem... NE555 to slow down my fans.

go to DL180 g5 download page and you'll get cp019157.exe for version 7.24

This document says that IOH ESI port has different device id (page 255). 8086:3403 = Intel 5500 chipset 8086:3406 = Intel 5520 chipset (on windows, check device manager -> Intel 5520/5500/X58 I/O hub to ESI port -> hardware ID)

Intel 5520 chipset -- 36 Lanes pci-express Intel 5500 chipset -- 24 Lenes pci-express maybe, some c6100 motherboards (DCS version?) use 5500 chipset.

Changing the zoning of expander I have a 2.5in expander, that zoning is upper12, lower12. I changed its zoning to upper4(HDD1-4), lower20(HDD5-24) by below operations. **** Fault operations may cause your expander to unusable! PLZ be careful! **** 1. Get xutil.exe tool from "DELL PowerEdge...

FIXED rate fan control (FCB version 1.21) There are three jumper pins on FCB(fan control board) marked as J2 near the MLB side, they are described "fan speed control jumper" on the hardware manual. I found some jumper patterns cause the fans to fixed speed rate. no jumper: automatic(default)...

Here is a c6145 system block diagram (estimated) The system works with one CPU on socket1. (w/o PCIe slot1/2)

I marked ? (HSI4...7 and HSO4...7) because they are not connected to mezzanine slot in that riser card. These signals from pci-e connector are connected like a loop-back (HSI4-HSO4, so on). # not a characterset translation issue... but i'm sorry for my poor english.

Great thanks to RB! c6100/c6145/c5220 mezzanine slot pinout (analyzing...)...
