Subject [jira] [Created] (CLOUDSTACK-6170) Support managed storage for root disks
Date Tue, 25 Feb 2014 19:08:19 GMT
Mike Tutkowski created CLOUDSTACK-6170:
------------------------------------------

             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.
