------------------------------------------
Summary: Support managed storage for root disks
Key: CLOUDSTACK-6170
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-6170
Project: CloudStack
Issue Type: Improvement
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
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).
This will require minor changes in the SolidFire (storage) plug-in.
The main changes are expected to occur in CloudStack logic that controls
hypervisors and additions to the way root-volume orchestration happens.
