AUTOMATIC POPULATION OF BOOT VOLUMES
A storage system ( 400 ) includes a storage processor ( 420 - 1 ) such as a storage card resident in a host server ( 410 - 1 ) and coupled to the storage device ( 450 - 1 ). The storage processor ( 420 - 1 ) may be configured to create a virtual volume ( 428 - 1 ), store content derived from an image ( 492 ) downloaded from a URL storage corresponding to the virtual volume ( 428 - 1 ), and present the virtual volume ( 428 - 1 ) to the host server as a boot LUN. A management infrastructure ( 480 ) can be used to create a library ( 490 ) of images ( 492, 494 ) corresponding to different storage system characteristics and used to selected which URL is provided to the storage processor ( 420 - 1 ).
1 . A processor, comprising:
one or more circuits to:
initialize a storage device controller installed in a server;
download, using the storage device controller, an image from a Uniform Resource Locator (URL) based on configuration data provided to the storage device controller;
generate, at least in part by writing content from the image to a virtual volume accessible to the host only through the storage device controller, a boot volume; and
cause the host server to be booted from the boot volume.
2 . The processor of claim 1 , the one or more circuits are further to:
select, based at least in part on the host, a template including the configuration data; and
provide the configuration data selected to the storage device controller.
3 . The processor of claim 2 , wherein the template is selected by a remote management system.
4 . The processor of claim 1 , wherein the configuration data can be provided to the storage device controller whether or not the host has fully booted.
5 . The processor of claim 1 , wherein the image may be downloaded by one or more additional storage device controllers.
6 . The processor of claim 1 , wherein the image downloaded is compressed, and the one or more circuits are further to:
uncompress the image downloaded before generating the boot volume.
7 . The processor of claim 1 , wherein the storage device controller is distinct from a central processing unit (CPU) of the host server.
8 . The processor of claim 1 , wherein the one or more circuits are further to:
generate, based at least in part on the configuration data, the virtual volume.
9 . The processor of claim 1 , wherein the storage device controller comprises at least one of a SPU, a storage card, or a storage service provider device.
10 . A system comprising:
a storage device controller, resident in a host server, to access a Uniform Resource Locator (URL), wherein the storage device controller is further to:
receive an image from the URL;
store content from the image to a virtual volume which is accessible to the host server only through the storage device controller; and
present the virtual volume as a boot volume for the host server.
11 . The system of claim 10 , wherein the storage device controller accesses the URL through the Internet.
12 . The system of claim 10 , wherein a management system provides the image at the URL.
13 . The system of claim 12 , wherein the management system selects, from among a plurality of images, the image corresponding to an operating system ran by the host server, wherein the plurality of images correspond to a plurality of different operating systems.
14 . The system of claim 12 , wherein the management system selects the image based on a template.
15 . The system of claim 10 , wherein configuration instructions are communicated to the storage device controller, the configuration instructions including the URL.
16 . The system of claim 10 , wherein the storage device controller comprises at least one of a SPU, a storage card, or a storage service provider device.
17 . A method comprising:
accessing a Uniform Resource Locator (URL) using a storage device controller that is resident in a host server;
receiving an image from the URL;
storing content from the image to a virtual volume which is accessible to the host server only through the storage device controller; and
presenting the virtual volume as a boot volume for the host server.
18 . The method of claim 17 , further comprising:
selecting the URL for the storage device controller;
communicating the URL to the storage device controller using a management system that is remote from the host server; and
maintaining the image at the URL.
19 . The method of claim 18 , wherein the selecting the URL includes selecting from among a plurality of URLs that are respectively associated with a plurality of images maintained by the management system.
20 . The method of claim 19 , wherein the plurality of images includes images respectively for different operating system.
21 . The method of claim 18 , wherein the selecting the URL includes selecting a storage template based at least in part on one or more characteristics of the host server, wherein the URL selected is associated with the storage template selected.
22 . The method of claim 17 , wherein the storage device controller comprises at least one of a SPU, a storage card, or a storage service provider device.
