Agnes Nepean asked 5 mesiacov ago Long term, these 2.5″ 4/5TB drives will slowly be replaced by 4TB SSD drives (presumably all NVMe). The SATA SSD boot drive stayed on the motherboard, 2 NVMe drives have been added to the combo (chipset-related except otherwise noted), Free slots and 4 of the 2.5″ SATA onerous drives had been positioned on the controller. On this specific motherboard, my recommendation could be to avoiding using them altogether if you can, except you either need the low-latency full-bandwidth path to the CPU or Slots your units are so energetic they by no means sleep anyway.
2) Devices all need to help ASPM L1. I ought to observe that finding NVMe drives which have working low-power APST energy states below ASPM isn’t all the time a given and you’ll want to perform a little research there too. I have been working at GitHub for 2 complete months! Writing out my thought process additionally helps me enhance my strategy and elicits helpful feedback from readers. That is a short and candy solution to get suggestions in your work in a specific, useful method!
L1 sub-states solely appear to get enabled on the chipset-connected Free Slots. First, power consumption without any drives connected to the cards (the SATA SSD boot drive is related to the motherboard) to get a baseline. An extra benefit is that I used to be able to use both of the ASM1166 playing cards within the system, whereas attempting to use each of my JMB575 cards at the identical time resulted within the system refusing to boot, though that might be a platform or motherboard-particular situation.
The reliability of SSDs plus my desire to extend the storage capability of this year’s DIY NAS resulted in me forgoing a second boot device. My past experience with ASMedia SATA controllers has been lower than stellar: reliability with the ASM1166 remains to be seen, free slots online however at the very least it’s a nasty candidate for Free slots a port multiplier since it doesn’t support FBS (only CBS). With baseline measurements full, next it was time to actually put some drives on these controllers. Shockingly, the JMB585 behaves in an opposite method where it’s consumption is decrease on the CPU-related slot (and Free slots online it didn’t trigger C2) – nevertheless, you’ll quickly see that issues change when drives are actually connected… With idle consumption as little as it’s during HDD standby, there isn’t a significant rush and this course of will steadily happen as my HDD drives/spares fail and SSD prices fall.
There is a commerce-off though – I all the time discovered the JMB585 to be rock-strong dependable, together Spin win with Free Slots when paired with a JMB575 port multiplier.
