Hello,
It's been months since I posted here. Today my home server runs a A4-4000 APU on a 6-SATA ports mainboard and 1 x 8 Gb memory module. Add to this 3 x 3 Tb Western Digital Red hard drives, and I get a consomption below 40W. I'm fine with this.
But today, I'd like to run virtualization on this server. Something like VMware ESXi would be perfect, but it requires a hardware RAID card.
Do some of you know any kind of hardware raid card, with low consumption, and, ideally, cheap ?
Thanks,
Low consumption hardware RAID card

Give a look here, if it may help: http://www.servethehome.com/lsi-host-bu ... omparison/
Re: Low consumption hardware RAID card
Thanks for pointing me to this documentation. But it's only related to recent boards, which are quite expensive.
What about old ones ? Does someone has a clue ?

Re: Low consumption hardware RAID card
That list is only HBAs, not RAID cards. Depending on the firmware type installed some LSI HBAs can do basic RAID, but it is BIOS/driver RAID, ie "FakeRAID". Those cards are great HBAs for JBOD or software RAID, but are not suitable for situations that need true hardware RAID like VMware.quest_for_silence wrote:Give a look here, if it may help: http://www.servethehome.com/lsi-host-bu ... omparison/
My unscientific tests puts an LSI 9260 at +15W from the wall when added to a system. That is a true hardware RAID card. Any true hardware RAID card is going to have a CPU and likely cache RAM which will add to its power draw.
Re: Low consumption hardware RAID card
Hi,
And thank you. I was already aware of the differences between fake-raid and real cards. But I can's manage to find, in the tech specs datasheets, the consumption of the cards (I searched for PERC series, P410, some Adaptec controllers)... Seems that no measurement is done ?
