Systems and methods for deployment of boot images in diskless servers
First Claim
1. A method to deploy a boot image in a diskless server in a computer system, comprising:
- initiating, in a remote management server coupled to a RAID controller in the computer system by an out-of-band communication link and without receiving a request from a first diskless server, a command to instruct the RAID controller to create at least a first logical volume in a memory module coupled to the RAID controller;
transmitting the command to the RAID controller via the out-of-band communication link;
in response to the command, creating, by the RAID controller, the first logical volume for the boot image;
transmitting a boot image from the remote management server to the RAID controller via the out-of-band communication link;
storing the boot image in the first logical volume;
assigning ownership of the first logical volume to the first diskless server in the computer system; and
initiating a boot operation for the first diskless server, wherein the first diskless server boots from the boot image in the first logical volume.

Abstract
In one embodiment, a system, comprises a first computer system comprising at least a first diskless server, at least a first RAID controller coupled to the first diskless server, at least a first storage pool coupled to the RAID controller, and a remote management server coupled to the RAID controller via a an out-of-band communication link. The remote management server comprises a boot management module which, when executed, initiates a command to instruct the RAID controller to create at least a first logical volume in a memory module coupled to the RAID controller, transmits the command to the RAID controller via the out-of-band communication link, and transmits a boot image from the remote management server to the RAID controller via the out-of-band communication link. The RAID controller creates the first logical volume for the boot image in response to the command, and stores the boot image in the first logical volume.

9. A system, comprising:
-
a first computer system comprising; at least a first diskless server; at least a first RAID controller coupled to the first diskless server; and at least a first storage pool coupled to the RAID controller; a remote management server coupled to the RAID controller via an out-of-band communication link and comprising a boot management module which, when executed; initiates a command to instruct the RAID controller to create at least a first logical volume in a memory module coupled to the RAID controller, wherein the command is initiated without receiving a request from the first diskless server; transmits the command to the RAID controller via the out-of-band communication link; and transmits a boot image from the remote management server to the RAID controller via the out-of-band communication link; and wherein the RAID controller; creates the first logical volume for the boot image in response to the command; and stores the boot image in the first logical volume. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
