Server 2012 R2 Storage Spaces versus Hardware RAID, how do you decide?
-
Interestingly, the Dell manual for the R620 says that the feature is enabled by default but it's disabled on mine ( which was a refub, so it could've been the previous owner or the Hosting company making guesses during initial set up ).
-
Looks like it can cause issues w/ ESX/ESXi, so if the box was used as a v-farm that could've been why.
-
Split that OBR10 into 2 Raid 0s, here's what each of them achieves now. That RAID tho.

So the RAID controller had a subtle, ambiguous setting available to switch it from PCIe 2 mode to PCIe 3 mode ( though it was labeled something more cryptic ). Simply enabling it made it jump from this:
Thank god for iDRACs.
Which setting was it that you changed from what to what?

It's in the system setup section, can't remember exactly where, but something along the lines of "set link speed to gen2/3", guessing that toggles the PCIe mode, thereby adding way more bandwidth between the drives and RAID controller. I don't have physical access to the servers at the moment so can't get in there to give you the exact info, sorry. But Link gen speed 2/3 should be enough to help you spot it if it's in your options.

LOL thought you loved iDRAC?

Does anyone use Spaces in production?
This is one old thread, wow!
-
@scottalanmiller And we're still no closer to having a production ready MS SDS product....

That's a sign of the developer having issues.

@dustinb3403 Or at least in my opinion a lack of interest and or resources. If we think about it from a business perspective, are they going to sell more Datacenter Licenses just because they have a viable SDS bundled with it? I'm not sure, but I'd guess probably not enough for them to dedicate what would likely be needed to get them there.

That would be my guess. Why did Windows Software RAID never get to production readiness? Because MS just didn't care. Users moved to hardware RAID, no one tried to use it, not something to be worried about.
-
@scottalanmiller Exactly, just above InfoPath on the priorities list.

They're currently sitting in boxes inbetween datacenters so unless you know about a more Harry Potterish version of iDrac that requires no electricity or Internet connection I don't think iDrac will help. :PPPP
