jack78 Posted September 24, 2017 Share #1 Posted September 24, 2017 Has anyone tried to connect 8 drives do HP Gen8 by additional card MiniSAS to SATA on 88SE9215 chipset? Is it possible? Quote Link to comment Share on other sites More sharing options...
sbv3000 Posted September 24, 2017 Share #2 Posted September 24, 2017 I would imagine that any 'supported' expansion card would work to give you 4 extra sata ports, but there might be power supply problems with the load, unless you used ssd or 2.5 inch drives, and you have to work out how to mount 8 drives in a small space.

jack78 Posted September 24, 2017 Author Share #3 Posted September 24, 2017 I think about this card http://s.aliexpress.com/NnAfqaqYI want to build external case for the additional drivesWysłane z mojego Redmi Note 4 przy użyciu Tapatalka Quote Link to comment Share on other sites More sharing options...
sbv3000 Posted September 25, 2017 Share #4 Posted September 25, 2017 That is a nice card, I'm using similar 8 port card with the marvel chipset and they work ok with the mvsas.ko driver module which is included in the 'extended' extra.lzma ramdisk created by @ig-88/@polanskiman. If you are planning to use an external drive bay then you will need to make sure that the drives spin up correctly before XPE boots so that both internal/external drives are available other wise your raid may crash. You might need some type of 'power relay timer' system that powers on the external bay first for cold boot and last for shutdown. Quote Link to comment Share on other sites More sharing options...
jack78 Posted September 25, 2017 Author Share #5 Posted September 25, 2017 I think, I will try to use power supply form my HP Gen8. Power supply has 200W, but in the current configuration, system used 54 Watts. One HDD use about 3 Watts in iddle, and 12 Watts in load. I have enough power reserve.

sbv3000 Posted September 26, 2017 Share #6 Posted September 26, 2017 I would check carefully the power supply 'rails' (12v/5v etc) on the 200w psu that it has enough capacity to handle 8 drives and the other system components. For example a WD Red 4 TB has a maximum 12v current of 1.75amps, which is probably the spinup maximum. If you have 8 drives = around 170 watts peak, dropping to say 100w/8.4amps in load. Remember that drives will 'spin up' from hibernation and demand the current, not just at boot. I have had problems with arrays where the PSU spec 'looked' ok but is couldn't handle the load and the SHR would randomly crash with different drives dropping from the controllers. Once I put a bigger PSU in it was fine. Quote Link to comment Share on other sites More sharing options...
jack78 Posted September 26, 2017 Author Share #7 Posted September 26, 2017 (edited) For now I need only 6 drives. But I must measure total power consumption on a power meter, for sure.If will be to much, then I exchange the PSU.

haldi Posted October 19, 2017 Share #8 Posted October 19, 2017 I'm using 4x WD Red 6TB. On my Celeron G1610T with 4gb RAM my system uses around 45W Idle If all the HDD's go into Sleep it's about 26W. If the HDD's spin up it shows a maximum of 80W, though i cannot say how accurate the measurement device can capture the peak. Migh be even more.

waazdakka Posted December 11, 2017 Share #9 Posted December 11, 2017 Hello haldi, I installed 4 internal and 4 external drives with almost the same card : s.aliexpress.com/NnAfqaqY My problem is my hard drives never enter sleep and have permanently 60W consumption What is your DSM version ?

haldi Posted December 14, 2017 Share #10 Posted December 14, 2017 Oh... If you want a working sleep mode you need to reset DSM and deactivate EVERY package and service.There are way too many things keeping your HDDs awake. I've given up on that on a Live system.
