B120i (in AHCI mode) + P222/P420(in RAID1) = fan noise?


Recommended Posts

Hello guys!


Before start writting about my doubt, I must say that I've been reading this forum for around two or three months. Since I looked this server as a potential purchase and I wanted to know all possible things about it.


I already bought it and it will arrive tomorrow. My setup is:


HP MicroServer G8 G1610T/2GB

2 x Kingston 8GB DDR3 1600 PC3-12800 ECC for HP

2 x WD NAS Red 1TB SATA3

1 x Kingston SSDNow V300 120GB


I plan (for now) to make a RAID1 with the 1 TB drives and install ESXi 5.1 or 5.5 there (o maybe install it in the microSD and use the RAID 1 volume as main datastore). As an option, I could instead install Ubuntu Server in this RAID1 and setup KVM. As you may see, my main purpose is using this server for virtualization. I plan to install the SSD in the ODD port, but won't be used for now,


Recently, Proxmox has caught my attention, I really really like it and would maybe prefer to use it instead of ESXi, recent version 4 is very neat and I'm sure version 5 will come with many interesting features. In that case, I'd like to put the Proxmox Installation in the SSD and use the RAID1 as datastore.

But, for what I've read, Debian (Proxmox's base) doesn't have a proper diver for the B120i controller, so, setting up a RAID0 for the SSD in the ODD port (for making it the booteable device) won't work with Proxmox. My first option, set the 
B120i in AHCI mode, but I couldn't have RAID1 and Proxmox for now doesn't support software RAID setup during installation, AND I'll be having the fan noise issue.


Nevertheless, I have in mind buying a hardware RAID (P222 or P420 for having iLO compatibility), within one month or two.


So, my idea with this card would be, making the 1TB drives RAID1 with the P222/P420 controller, and set the B120i in AHCI mode to boot from the SDD drive in the ODD port (after installing Proxmox there of course).


Now, my questions are, since I'm not sure about the whole B120i-in-ahci-fan-noise issue:


1- Having a RAID1 with the P222/P420 and the B120i in AHCI mode will trigger the fan noise bug?
2- Will this latter configuration be possible?


Many, Many thanks in advance!

The fan speed issue has been fixed for over a year now. You're reading old threads with bad info so it is perpetuating the idea that AHCI = fan noise.


But, for what I've read, Debian (Proxmox's base) doesn't have a proper diver for the B120i controller, so, setting up a RAID0 for the SSD in the ODD port (for making it the booteable device) won't work with Proxmox. My first option, set the 

The B120i controller is just the Intel SATA controller with custom firmware + driver. If you're missing the driver in your OS then it'll just work like an AHCI controller since your OS talks directly to the controller anyway.


B120i in AHCI mode to boot from the SDD drive in the ODD port

The SATA controller in AHCI mode doesn't support booting from the ODD port and you don't want to plug a SSD into there anyway because it is limited to 3Gbps. As you're installing a SAS/SATA controller into the PCIe slot, the SATA controller on the motherboard is no longer connected to the drive cages. This means you can plug in a SFF-8087 to discrete SATA forward breakout cable to use the 4 ports that were connected to the drive bays. Port 1 + 2 on that connector run at 6Gbps. Port 3 + 4 and the ODD port only run at 3Gbps.


Make sure it is a forward breakout cable. There is a reverse breakout cable which won't work.

Thank you SO much for this information!! And to think that I've been reading so many old info.
But... even in that case,.. I haven't found a thread about the solution for the fan noise problem. Do you have any link I could read or maybe some steps to follow?


I really thank you dude! This fan noise issue was my first concern.


Also, being able to use the 6 GB/s ports for the SDD drive is super!!

Just flash ilo to latest and bios to latest

and there is no fan speed issue

Thanks for the Reply Shonk, 


Quoting the main links page it would be like:


1976dan: Word of advice before u do anything besides unboxing your micro server

Plug in power

Plug in keyboard

Plug in mouse

Plug in monitor

Plug in network cable

Boot it up and press f10 and update your firmware of your micro server and this will Most prob fix a lot of problems..


Like that? or by any other special procedure (manually downloading files, etc)? 


Thanks again.

I just had to register and ask this: Is the fan issue really one-hundred-percent fixed nowadays? I'm idling my gen8 at a comfortable 6 % fanspeed atm, according to iLO. Would this still hold true if I install a P222 or P420?


Any clarification is greatly appreciated.

Well, I don't know for a P222 or a P420 card (I'm using B120i ). I've already tried RAID1 mode with ESXi 5.5 U1 and fan was at 6%


Like an hour ago I switched to AHCI mode and installed ESXi 5.5 U2 in the disk inside the bay 1, right now I'm installing a CentOS 7 VM and fan is at 12% but still very silent.


EDIT: add information about firmware (my server arrived just yesterday)


System ROM J06 System ROM Date 06/06/2014

Backup System ROM Date 06/06/2014

iLO Firmware Version 2.10 Jan 15 2015

Any RAID controller Card or low power Video Card in the expansion slot will add heat which should cause the fan to run more -- which has been my experience.  You can check some of the links in the links Thread for supplemental cooling of that area http://homeservershow.com/forums/index.php?/topic/5639-proliant-microserver-gen8-links/


and here are some other ideas http://homeservershow.com/supplemental-cooling-gen8-microserver-p222.html

      Good afternoon folks!
      I have a question I was wondering if someone would know about. I have a Microserver Gen 8 with Vmware ESXI 7 currently installed on the MicroSD with AHCI enabled instead of RAID mode (dont find anything usefull in raid mode in my current setup other than booting from ODD, which I can just use as another Datastore instead).
      With that context being said, Im trying to enable the Agentless Management Service from the ILO with the drivers on the Vmware ESXI 7, but unfortunetly after installing and trying to start the service with:

      /etc/init.d/hp-ams.sh start  
      I get the following error:
      /opt/hpe/ams/amshelper: error while loading shared libraries: libnicmgmt.so.0: cannot open shared object file: No such file or directory  
      Makes sense following the Vmware ESXI HPE support matrix, since its only supported until Vmware ESXI 6.5U2 Pre-gen. But I´ve been reading lots of people having working setups doing the following:
      Install Vmware ESXI HP Custom Image 6.5U2 -> Offline Update to Vmware ESXI 6.7.
      I was wondering if installing HP Custom Image 6.5U2 with the drivers Agentless Management Service working and doing a full upgrade to ESXI 7.0 would do the trick, since its an upgrade not a clean install...so libraries should stay supporting older drivers installed.
      Does this make any sense?? Has anyone gone trough this alredy?

      I have been running the WHS1 pack 3 for many years.  Unfortunately it is no longer working.  I got a Proliant microserver Gen10 hoping it will run it but was unable to install the software.  The software should run on most older PCs?

      Does anyone have the WHS1 running on the Gen10?  Also my WHS1 iso is Pack 1.  If I manage to install the Pack 1 can I find on the web the upgrade to pack 3?  Would I be forever stuck at Pack 1?  Any advice would be appreciated.

      All credit to schoondoggy for his original idea. A shame I am on the wrong side of the Atlantic to order an SDM kit as the import duties make it an expensive option, or would have if they were still available. I had to look around to see what alternatives I could find... and managed to find the bits needed on Amazon!
      I must admit I am rather pleased with the end result of this project and may repeat it on the other Gen8 MicroServer. The outcome is a server with a mirrored system drive on the internal B120i, and the main drive bays connected to an HP P222 card providing a RAID-10 data volume. This is pretty much my ideal setup for a stable resilient but small server.
      Sabrent 3.5" to x2 SSD Internal Mounting Kit (BK-HDCC)
      Amazon UK - https://amzn.to/32qEVou
      Amazon US - https://amzn.to/3h8Blom
      The kit comes with all the cabling you need and all the required screws to mount the drives and bracket.
      Two types of power splitter cables are included along with two SATA cables. The bracket holds two SSDs and provides a small gap between them.
      I mounted the bracket next to the PSU but leaving a 2-3mm gap to allow for some airflow past the SSDs in case they get warmed by the P222.
      Put some insulating tape along the underneath of the upper chassis rail next to the PSU and drilled three small holes.
      I used two strips on to stop the drill bit from walking across the metal. Drill with a 2mm first then a 2.5mm bit. This leaves enough metal for screws to thread in.
      Check and measure each hole against the bracket as you go so that they line up. Bracket is then fixed in place using the provided screws (see photo).
      The final part of the puzzle is another Mini-SAS to SATA cable the same as the one connected to the internal drive bays.
      This is an SFF-8087 Mini-SAS [male] connector to 4 SATA [female] header cables. The 50cm cable from Jyopto works great and not too much spare to lose within the system.
      Amazon UK - https://amzn.to/2CXAzgb
      I could not find it on Amazon US site but there was one from CableCreations that same length.
      Just need to add your choice of SSDs and cable up to B120i port.  I went with Samsung 860 Pro SSDs for the longer rated lifespan of write cycles.
      I decided to forget about an internal DVD/RW drive and opted for an external HP F2B56AA slimline drive that can be plugged into the USB of either system.
      Amazon UK - https://amzn.to/2EgSSxD
      Amazon US - https://amzn.to/326uFmL
      Sabrent also make a really good quality 2.5" to 3.5" bay converter adapter (BK-PCBS) that I have used in the EX490/X510 to convert from HDD to SSD system drives.

      Hopefully this information will prove useful to some looking to update their MicroServer.

      Hi! I am planning to buy a Microserver Gen10 Plus E-2224 for a small business, and want to add as much disk space as possible. I already have the older Gen10 with 4x4TB HDDs in RAID10 (effective capacity 8TB) and a 2TB SSD in the 5th slot (which is missing on the new G10 plus). The max stated capacity on the HPE site seems to be limited with their own enterprise HDDs, so I'd like to see if I can go for bigger disks. The server would be running a sort of an application which collects lots of data from devices, and the data tends to grow over time (1-2TB per year), and I'd prefer not to worry about the capacity for the next several years.
      My primary concern is the max capacity (max single drive capacity + max total RAID capacity with the Smart Array S100i) I can reliably install. If possible, some actual setup which has been shown to work with 32GB RAM and its limited 180W power supply? I was also planning on upgrading it to 32GB. If I am buying a 16GB RAM server, does this means it has both slots occupied with 8GB modules and I need a 2x32GB kit? For the os SSD, I won't have the PCIe slot available because we need to insert a certain GPS PCIe card that the server uses for time synchronization. So, if I want an SSD, this means I should use something like 1xSSD + 3xHDD in RAID5, instead of RAID10?  
      I've been planning to install 16TB Seagate Exos X16 drives, with rated max operating power at 10W (6.3W for random reads/writes). Does this seam feasible?
      Thanks a lot for your tips!
