I manage all my bulk storage using ZFS (similar to storage spaces), and it makes me feel comfortable knowing that I could recover a set of disks out of a server and rebuild them on any commodity hardware. You still would not use it for the system drive. Storage spaces in 2012 is much better, but is it's own beast. No multi-level arrays, no hot swapping, no hot spares. In the disk manager in 2008, you get RAID 0, 1, and 5. #Softraid windows 10 software#I would not recommend using software RAID to protect your system drive. My suggestion is that soft RAID is great for bulk storage, poor for availability for system drives. RAID field experience is what I primarily want - not just technical but general 'sense' of how things would work - but that being said any links I can be directed to for technical comparison of the scenarios I have outlined that would be appreciated as well. How much difference would adding 500 meg of cache to each controller be so that the aggregate is 1 gig just as with the expensive controller?ĭoes Windows software mirroring allow for 'spare ready-to-go' hot swap as is available in RAID configurations - you setup an extra drive in the RAID unit that lays dormant until such time as a failure of a drive in the RAID and then it gets swapped in automatically. Would the size of the drives make a difference e.g. I know it's difficult to give hard numbers but approximately what kind of a hit would there be with scenario 1 - RAID - vs scenario 2 - simple software mirror - vs scenario 3 - dual controller mirroring? ability to move the drives and/or controller to another system if there should be a problem. In the latter two cases the obvious extra cost is more drives but let's say ease of transportability is determined to be worth it in this case - e.g. With a software mirror I could at the low end just have two arrays of 10 TB drives on a single drive chain.Īt the high end for mirroring I could have 2 not so top of the line controllers with minimcal cache, let's say - each at half the price of the expensive controller (which is approximately correct for some actual gear I've scoped out) - each controller with its own chain of drives. With a hardware RAID I would have a high end RAID controller with a good chunk cache - let's say 1 gig - and then add a pile of drives - let's assume SATA for this discussion - that would end up being more than 10 TB depending on the type of RAID I wanted. We have had quite a few discussions about the differences between hardware and software RAID and I am hoping I can get some input on the topic.įor instance let's say I had 10 TB I wanted to mirror as opposed to hardware RAID'd.
