Abstract

Large-scale data migration processes are managed using a schedule optimizer implemented in software. The schedule optimizer assigns an available data migration window to each server in an inventory of servers based on a scheduling priority determined for that server. For example, servers that have manually scheduled conversion dates are assigned the highest scheduling priority, and servers that have a migration deadline are assigned the next highest scheduling priority. In addition, servers may grouped and data migration may be scheduled for server groups instead of individual servers.

Claims

1. A physical-to-virtual conversion system, comprising:

a plurality of source machines;

one or more physical servers having virtual machines instantiated therein, wherein each of the plurality of source machines is associated with a different one of the virtual machines; and

a computer system comprising one or more processing units and memory storing instructions that, when executed by the one or more processing units, enable;

a physical-to-virtual conversion system for migrating data of each of the plurality of source machines to the associated virtual machine instantiated in the one or more physical servers; and

a scheduling system that is configured to schedule data migration of the plurality of source machines to the virtual machines by assigning the plurality of source machines to one or more time periods for migration based on priority that is in accordance with a hierarchically arranged set of rules, wherein;

source servers that have been manually scheduled for physical-to-virtual conversion are scheduled for data migration first and accordingly assigned a first priority based on being manually scheduled instead of not being manually scheduled, thereby providing the first priority within the hierarchically arranged rules; and

source servers that have not been manually scheduled for physical-to-virtual conversion are scheduled for data migration second and accordingly assigned one of one or more second priorities based on not being manually scheduled instead of being manually scheduled, thereby providing the one or more second priorities within the hierarchically arranged rules.

2. The system of claim 1, wherein the scheduling system is configured to schedule the data migration in accordance with the hierarchically arranged set of rules based on one or more of one or more source machine properties of each of the plurality of source machines, one or more resource limits or constraints of physical resources that carry out the data migration, or one or more runtime parameters of the scheduling system.

3. The system of claim 2, wherein the scheduling system is configured to schedule the data migration in accordance with the hierarchically arranged set of rules based on the one or more source machine properties of each of the plurality of source machines, the one or more source machine properties comprising one or more of one or more addresses associated with the one or more physical servers, a data size of data of each of the plurality of source machines, an operating system of each of the plurality of source machines, a group identifier, a phase identifier, a migration deadline, a schedule migration date, or a maintenance window.

4. The system of claim 1, wherein the scheduling system is configured to schedule the data migration in accordance with the hierarchically arranged set of rules based on grouping of the plurality of source machines into groups.

5. The system of claim 1, wherein the scheduling system is configured to schedule the data migration of a source machine, at a time for scheduling said source machine, into a first available data time period of the one or more time periods.

6. The system of claim 1, wherein the set of rules comprise at least three hierarchically arranged rules.

7. A method of scheduling physical-to-virtual conversion of a plurality of source machines to virtual machines instantiated on one or more physical servers, each source machine associated with a different one of the virtual machines, the method comprising:

assigning, by a scheduling system of a computer system, the plurality of source machines to one or more time periods for migration based on priority that is in accordance with a hierarchically arranged set of rules to schedule data migration of the plurality of source machines to the virtual machines, the assigning comprising;

assigning, by the scheduling system, a first priority to those source servers that have been manually scheduled for physical-to-virtual conversion based on being manually scheduled instead of not being manually scheduled; and

assigning, by the scheduling system, a lower priority than the first priority to those source servers that have not been manually scheduled for physical-to-virtual conversion based on not being manually scheduled instead of being manually scheduled; and

migrating, by a physical-to-virtual conversion system of the computer system, data of each of the plurality of source machines to the associated virtual machine instantiated in the one or more physical servers during the assigned time period.

8. The method of claim 7, wherein the scheduling system is configured to schedule the data migration in accordance with the hierarchically arranged set of rules based on one or more of one or more source machine properties of each of the plurality of source machines, one or more resource limits or constraints of physical resources that carry out the data migration, or one or more runtime parameters of the scheduling system.

9. The method of claim 8, wherein the scheduling system is configured to schedule the data migration in accordance with the hierarchically arranged set of rules based on the one or more source machine properties of each of the plurality of source machines, the one or more source machine properties comprising one or more of one or more addresses associated with the one or more physical servers, a data size of data of each of the plurality of source machines, an operating system of each of the plurality of source machines, a group identifier, a phase identifier, a migration deadline, a schedule migration date, or a maintenance window.

10. The method of claim 7, wherein the scheduling system is configured to schedule the data migration in accordance with the hierarchically arranged set of rules based on grouping of the plurality of source machines into groups.

11. The method of claim 7, wherein the scheduling system is configured to schedule the data migration of a source machine, at a time for scheduling said source machine, into a first available data time period of the one or more time periods.

12. The method of claim 7, wherein the set of rules comprise at least three hierarchically arranged rules.

13. A non-transitory computer-readable storage medium containing instructions for causing a computer system to carry out a method of scheduling physical-to-virtual conversion of a plurality of source machines to virtual machines instantiated on one or more physical servers, each source machine associated with a different one of the virtual machines, the method comprising:

assigning, by a scheduling system of the computer system, the plurality of source machines to one or more time periods for migration based on priority that is in accordance with a hierarchically arranged set of rules to schedule data migration of the plurality of source machines to the virtual machines, the assigning comprising;

assigning, by the scheduling system, a first priority to those source servers that have been manually scheduled for physical-to-virtual conversion based on being manually scheduled instead of not being manually scheduled; and

assigning, by the scheduling system, a lower priority than the first priority to those source servers that have not been manually scheduled for physical-to-virtual conversion based on not being manually scheduled instead of being manually scheduled; and

migrating, by a physical-to-virtual conversion system of the computer system, data of each of the plurality of source machines to the associated virtual machine instantiated in the one or more physical servers during the assigned time period.

14.
