Abstract

In one embodiment, the present invention includes a method for receiving a request for power-up of a first blade of a chassis, enabling the first blade to power-up in a reduced boot mode and receiving a communication including characteristic information and policy information associated with the first blade, and analyzing the characteristic information and the policy information to determine a policy and a boot configuration for the first blade. Other embodiments are described and claimed.

Claims

1. A method comprising:

receiving, in a manager of a chassis having a plurality of blades, at least some of the blades being heterogeneous, a request for power-up of a first blade of the chassis;

enabling the first blade to power-up in a reduced boot mode and receiving a communication from the first blade in the manager, the communication including characteristic information and policy information associated with the first blade;

analyzing the characteristic information and the policy information with respect to resources of the chassis and determining a policy and a boot configuration for the first blade based on the analyzing.

2. The method of claim 1, further comprising authenticating the first blade and reporting a conflict to a remote administrator if the conflict is determined.

3. The method of claim 1, further comprising communicating the policy and the boot configuration to the first blade, and restarting the first blade to boot into a boot mode indicated by the boot configuration.

4. The method of claim 3, wherein communicating the policy is to instruct the first blade to disable at least some components of the first blade based on the resources of the chassis.

5. The method of claim 3, wherein communicating the policy is to instruct the first blade to consume less than a predetermined threshold of power based on at least one of blade capacity, chassis location or available air flow.

6. The method of claim 3, wherein communicating the policy is to instruct the first blade to execute only trusted applications on the first blade, wherein the first blade includes a secure operating system (OS), and further comprising communicating a second policy to a second blade of the chassis to execute only untrusted applications on the second blade, wherein the second blade includes an untrusted OS.

7. The method of claim 1, wherein the first blade is provided with minimal power in the reduced power mode and a plurality of components of the first blade are disabled in the reduced boot mode.

8. The method of claim 2, wherein authenticating the first blade comprises sending an encrypted challenge request from the manager to the first blade and receiving a decrypted version of the encrypted challenge request from the first blade, wherein the first blade decrypts the encrypted challenge request with a private hash.

9. An article comprising a machine-accessible medium including instructions that when executed cause a system to:

receive, in a manager of a chassis having a plurality of blades, at least some of the blades being heterogeneous, a request for power-up of a first blade of the chassis;

enable the first blade to power-up in a reduced boot mode and receive a communication from the first blade in the manager, the communication including characteristic information and policy information associated with the first blade;

analyze the characteristic information and the policy information with respect to resources of the chassis and determine a policy and a boot configuration for the first blade based on the analysis.

10. The article of claim 9, further comprising instructions that when executed cause the system to authenticate the first blade and report a conflict to a remote administrator if the conflict is determined.

11. The article of claim 9, further comprising instructions that when executed cause the system to communicate the policy and the boot configuration to the first blade, and restart the first blade to boot into a boot mode indicated by the boot configuration.

12. The article of claim 11, wherein communication of the policy is to instruct the first blade to execute only trusted applications on the first blade, wherein the first blade includes a secure operating system (OS), and to instruct a second blade of the chassis to execute only untrusted applications on the second blade, wherein the second blade includes an untrusted OS.

13. A system comprising:

a plurality of blades, at least one of the blades having heterogeneous resources; and

a chassis manager coupled to the plurality of blades, wherein the chassis manager is to receive a request for power-up of a first blade of the plurality of blades, enable the first blade to power-up in a reduced boot mode and receive a communication from the first blade, the communication including characteristic information and policy information associated with the first blade, and analyze the characteristic information and the policy information with respect to resources of the system and determine a policy and a boot configuration for the first blade based on the analysis.

14. The system of claim 13, wherein a first blade of the plurality of blades is to be provided with minimal power in the reduced power mode and a plurality of components of the first blade are to be disabled in the reduced boot mode.

15. The system of claim 14, wherein the chassis manager is to send an encrypted challenge request to the first blade and receive a decrypted version of the encrypted challenge request from the first blade, wherein the first blade is to decrypt the encrypted challenge request with a private hash.
