This document defines policies for the UT Virtual (UT-V) service from ITS and is supplemental to the UT-V SLA.
Notes on Provisioning
- Due to algorithms for CPU scheduling in the VMware vSphere infrastructure, VMs with overprovisioned vCPU may experience poor performance and have a negative impact on the UT-V service. UT-V administrators will work with Customers to optimize VM configuration, including vCPU provisioning.
- VMs that require non-standard OS/RAM/Swap configurations may run into resource contention issues. UT-V administrators will work with customers to determine optimal settings.
- UT-V can only provision VMs on VLANs that are present in UDC-C. UT-V administrators will work with Customers to review requests for unique vLAN requirements.
- UT-V VMs are provisioned on the austin.utexas.edu domain or the its.utexas.edu domain by default. UT-V administrators will work with Customers to review requests for unique DNS requirements.
- UT-V is subject to all maximums and limitations of the physical hardware and vSphere infrastructure.
- It is recommended that customers run the swap file on Tier 1 storage for better performance.
Legacy Data Protection for UT-V
- Legacy UT-V VMs continue with legacy backup process which includes the following characteristics:
- OS drive backup
- Weekly full backup
- Data stored on non-OS drives cannot be recovered by UT-V administrators
- UT-V OS drive backups do not provide versioning.
- Requests for OS drive restoration must be made through a Footprints ticket which can be submitted via the ITS Helpdesk.
- OS drive restorations provide image level recovery.
- After an OS drive restoration, original OS drives are deleted after 7 days.
- Data stored on Mid-Tier Performance Storage (Tier 2) cannot be recovered by UT-V administrators.
New Data Protection for UT-V
- New VMs, as of October 6, 2014 will be backed up completely on a daily basis, including all virtual disks. An opt-out option is available on the VM request form.
- Existing VMs can opt-in for complete VM backups, by submitting a Footprints ticket via the ITS Helpdesk.
- Storage for complete VM backups is charged at the backup storage rate based on the size of the virtual disks.
- Requests for VM, virtual disk, and file level restoration must be made through a Footprints ticket which can be submitted via the ITS Helpdesk.
- After any VM or virtual disk restoration, original VM or virtual disk is deleted after 7 days.
- UT-V does not provide VM-specific OS or system-level administration.
- UT-V is not designed to provide disaster recovery capabilities.
- UT-V does not integrate with any non-ITS owned hardware.
- Customers must provide the media and license keys for any OS or applications.
- Customers must install and keep current the VM Hardware and Tools for their VMs.
- UT-V Customers are encouraged to request VM snapshots prior to performing high-risk maintenance on their VMs.
