Mike Tutkowski commented on CLOUDSTACK-6170:
--------------------------------------------
I had accidentally listed this ticket as an Improvement instead of a New
Feature. Just changed that.
It's a bit of a grey area in which category this ticket falls. I am adding
support for root disks on XenServer for managed storage (managed storage was
first added in 4.2).
> Support managed storage for root disks
> --------------------------------------
>
> Key: CLOUDSTACK-6170
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-6170
> Project: CloudStack
> Issue Type: New Feature
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: Management Server
> Affects Versions: 4.4.0
> Environment: I expect to support managed storage for root disks on
> XenServer and ESX (KVM is targeted for 4.5).
> Reporter: Mike Tutkowski
> Assignee: Mike Tutkowski
> Fix For: 4.4.0

>
> Cloud environments have a need for guaranteed storage performance. By this I
> mean having the ability to specify a minimum and maximum number of IOPS on a
> volume-by-volume basis.
> I added support for this for XenServer and ESX in 4.2 for data disks.
> I added support for this for KVM in 4.3 for data disks.
> It is my intent to add support for this for XenServer and ESX in 4.4 for root
> disks (with subsequent support for root disks on KVM expected in 4.5).
> The main changes are expected to occur in CloudStack logic that controls
> hypervisors and additions to the way root-volume orchestration happens.
> This will also require minor changes in the SolidFire (storage) plug-in.
