G8 Microserver - Be aware of Fan issue, add in cards


Recommended Posts

This must be a bug, the state of the internal RAID-controller should not affect the fan!

Even if we elaborate that enabling the RAID-controller produce more heat the fan shouldn't spin a at lower pace than in the AHCI mode :)

 

If you enter bios and check the boot order when you have the two raid controllers active, can you see them in the options?

Yes, it is an official ROM from HP.   The readme file contains the following info   Enhancements/New Features:   - Added additional options to the ROM Based Setup Utility (RBSU) Power-On Delay Opt

After a Bank Holiday morning of testing I have the Two Arrays working fine with decent fan speeds. (I'm running Windows 8 Pro as a server)   To me it seems that the iLO4 doesn't always see the PCI R

Yes. All works as you would expect apart from ILO4 and hence the fan control. Something's wrong somewhere as from boot to boot I can see both in iLO4 but fan still high then neither showing in iLO4. I've spent too much time on this for now so just restored back to using just the B120i with the 4 bays as a RAID10 array and the SSD as a RAID0 in the optical connector.  May retry again at a later stage.

I have a SSD running in AHCI mode in the SATA port and a Adaptec 3405 adapter with 4 x 3TB drives in RAID 5 and my fans are running at 28%

Does ILO4 show anything under the storage Tab? What drives are you using?

 

Also for those more experienced, will HP P222 work in any PC or does it have to be an HP machine?

Are you familiar with the process of running a single drive on a HP Smart Array controller? If not you need to make a single drive RAID0.

 

This is also a weird requirement. Who on earth thought that one up :wacko:

Doesn't show anything and Toshiba 3TB, cant remember the model numbers.

It's interesting how HP ties seemingly unrelated items together, like a RAID card controlling the system cooling fan.

How would these be unrelated? RAID=Drives=heat

Also, the RAID card is not controlling the fans the iLo is

When did you become head critic of RAID controllers?

The Smart Array controllers did not have a JBOD mode. This was an innovative way of providing JBOD.

I have used HP RAID controllers in non-HP systems. They have worked fine.

Well, let's see: the fan is to cool the system, not just the drives, cause all of it generates heat, so why not have the system control the fan? I guess the iLO controlling it is more logical; better than the RAID card anyway.

 

A single drive RAID0 is a contradiction in terms, and is in direct violation of the official definition of RAID0. Call me old-fashioned; I like things to be logical and follow the established standards. Why didn't HP just label it 'individual drive mode' or something? Also, what happens if you have multiple drives and want them all to be seen individually by the system; do you have to make multiple RAID0 arrays? On other RAID cards, the default is to just have all drives seen individually, unless you deliberately create an array of some level. BTW, just like everyone else, I'm entitled to criticise HP's implementation -- don't have to be the head of anything. You call it innovative... fair enough; I call it weird, non-standard, illogical, and non-intuitive. :)

Something funky is going on with fan control. I added 2x 2.5" HDD's in top ODD bay and connected them to the B120i and created a RAID 1 array loaded up ESXi and suddenly the fan keeps running at 70% when it has been keeping a nice 6% duty mode before. All the temperatures are very low and nice.

 

Could the inital array creation cause the fan to increase so much?

The system does control the fan through iLo, that was my point. 

 

Of course you are welcome to criticize anything you like.
