Need to Improve Disk Utilization on XenServer 7.2
-
Scott with consideration for the total amount of ram, cache, cpu power etc, why is the world still stuck on "hardware raid" ?!?! Seems to me like it needs to die lol.

Because it solves a few important problems:
- It is large profits based off of people not understanding RAID systems. So it's not going anywhere for business reasons.
- It enables simple separation of duty between IT and bench staff. No IT needed for disk replacements.
- It allows systems like VMware ESXi, Citrix XenServer that lack software RAID and systems like Hyper-V that have no good software RAID to still work well.
- It allows simple cache mechanisms to be made available to staff that could not configure it safely in software.
- It allows for low cost work arounds to unreliable power systems.

Wish Google would fix this problem
but seriously, thanks for your help. I have clarity now on the matter. -

LVM and XFS most likely. The installers can be a little confusing if you don't know about how LVM works. https://mangolassi.it/topic/11302/travis-hershberger-linux-lvm-storage

@travisdh1 so XenServer will let me do that 3rd option?! Never heard of it and Iām about to google it.

Oh, XenServer? Yeah, you want EXT then. Only option that allows thing provisioning in XenServer, also one of the reasons XS has fallen out of favor around here.

Ok gonna nuke it and redo it as EXT

Hell im anxious to see how fast my work cluster is cause this is crazy at home

So when I first install XenServer and I "tick" thin provisioning, behind the scene it's making the drive ext, so I assume if I didn't choose thin provisioning it would have made it LVM?
