Abstract

One embodiment is a method for booting a bootable virtual storage appliance on a virtualized server platform. One such method comprises: providing a virtual storage appliance on a server platform, the virtual storage appliance configured to manage a disk array comprising a plurality of disks, and wherein at least one of the disks comprises a hidden boot partition having a boot console; powering up the server platform; loading boot code on the server platform; loading the boot console from the hidden boot partition; and the boot console loading boot components for a virtualization environment.

Claims

1. A method for booting a bootable virtual storage appliance on a virtualized server platform, the method comprising:

providing a virtual storage appliance on a server platform, the virtual storage appliance configured to manage a disk array comprising a plurality of disks, and wherein at least one of the disks comprises a hidden boot partition having a boot console;

powering up the server platform;

loading boot code on the server platform;

loading the boot console from the hidden boot partition; and

the boot console loading boot components for a virtualization environment.

2. The method of claim 1, wherein the virtual storage appliance comprises a guest operating system associated with the server platform.

3. The method of claim 1, wherein the virtual storage appliance comprises a RAID controller.

4. The method of claim 1, wherein the virtualization environment comprises a virtual machine monitor that supports the virtual storage appliance and a plurality of virtual machines executing different operating systems.

5. The method of claim 1, wherein the boot code loads one of a BIOS environment or an EFI environment.

6. The method of claim 1, wherein the disk array comprises a hard disk drive array.

7. The method of claim 1, wherein the disk array comprises a storage area network.

8. The method of claim 1, wherein the disk array comprises a RAID array.

9. The method of claim 1, further comprising managing the virtual storage appliance.

10. The method of claim 1, wherein the providing the virtual storage appliance comprises installing the virtual storage appliance on the server platform by:

providing an installation package accessible by the server platform, the installation package comprising an installation script for installing the virtual storage appliance, a boot console, and a management module;

powering up the server platform and loading the boot code;

loading the installation package to run on top of the boot code;

running the installation script to create the hidden boot partition on the disk and copy the boot console and the management module to the hidden boot partition;

rebooting the server platform and loading the boot code;

loading the boot console and the management module from the hidden boot partition;

configuring the disk array via the management module;

creating a hidden boot partition, and replicating the boot console and the management module, on each disk in the disk array; and

installing the virtualization environment using the boot console as a storage driver.

11. The method of claim 10, wherein the installation package is provided to the server platform via at least one of a compact disk, a digital video disk, and a flash memory device.

12. The method of claim 10, wherein the installing the virtual storage appliance on the server platform further comprises rebooting the server platform.

13. The method of claim 12, wherein the rebooting the host server platform comprises:

loading the boot console and the management module from the hidden boot partition on one of the disks; and

the boot console loading the virtualization environment.
