Abstract

Disclosed is a slot availability indication system including a RAID, at least one disk tray defining a first slot, second slot, and third slot, the first, second, and third slots being configured to contain a drive and being associated with the RAID, a RAID light indicator, a first, second, and third disk activity light indicator, and a first, second, and third disk availability light indicator disposed on the trays, the RAID being configured to flash the RAID light indicator and the first, second, and third activity light indicators when at least one of the first, second, and third slots in at least one of the trays is empty, the RAID being associated with and configured to flash the first availability light when the first slot is empty, the second availability light when the second slot is empty, and the third availability light when the third slot is empty.

Claims

1. A slot availability indication system comprising:

a blade chassis defining a plurality of blade slots;

a RAID controller disposed in at least one of said blade slots;

a battery component disposed in at least one of said blade slots;

at least one disk tray disposed in at least one of said blade slots, each of said at least one disk trays defining a first disk slot, a second disk slot, and a third disk slot disposed in depth, each of said first disk slot, said second disk slot, and said third disk slot being configured to contain a disk drive, and being logically associated with said RAID controller;

a RAID light indicator disposed on said RAID controller, said RAID light indicator being logically associated with said first disk slot, said second disk slot, and said third disk slot of each of said at least one disk trays and said RAID controller, said RAID controller being logically configured to flash said RAID light indicator when at least one of said first disk slot, said second disk slot, and said third disk slot in at least one of said at least one disk trays is empty;

a first disk activity light indicator disposed on each of said at least one disk trays, a second disk activity light indicator disposed on each of said at least one disk trays, and a third disk activity light indicator disposed on each of said at least one disk trays, wherein said RAID controller is logically associated with and configured to flash said first disk activity light, said second disk activity light, and said third disk activity light of any of said at least one trays in which at least one of said first disk slot, said second disk slot, and said third disk slot is empty; and

a first disk availability light indicator disposed on each of said at least one disk trays, a second disk availability light indicator disposed on each of said at least one disk trays, and a third disk availability light indicator disposed on each of said at least one disk trays, wherein said RAID controller is logically associated with and configured to flash said first disk availability light when said first disk slot is empty light, said second disk availability light when said second disk slot is empty, and said third disk availability light when said third disk slot is empty.

2. The slot indication system of claim 1, wherein said at least one disk tray is disposed within a storage sub-system domain.

3. The slot indication system of claim 1, wherein said RAID controller is logically associated with at least one storage sub-system domain, and wherein each of said at least one disk trays including said disk slots that are logically associated with said RAID controller are disposed in one of said at least one sub-systems logically associated with said RAID controller.

4. The slot indication system of claim 1, wherein each of said first disk slot, said second disk slot, and said third disk slot each include a disk detection device configured to detect presence of said disk drive.

5. The slot indication system of claim 4, wherein said disk detection devices are logically associated with said RAID controller.

6. The slot indication system of claim 1, further including two tray light indicators disposed on each of said at least one disk trays, said two light indicators being logically associated with said RAID controller, said RAID controller being logically configured to flash at least one of said two tray light indicators disposed on any of said at least one trays in which at least one of said first disk slot, said second disk slot, and said third disk slot is empty.

7. The slot indication system of claim 6, wherein said a RAID light indicator, said first disk activity light, said second disk activity light, and said third disk activity light, said first disk availability light, said second disk availability light, and said third disk availability light, and said two light indicators are each configured to be bi-color.

9. The method of claim 7, further including flashing at least one of two tray light indicators disposed on said disk tray and logically associated via said RAID controller with said three disk slots that include said at least one empty slot.

8. A method of indicating slot availability, the method comprising:

initiating available slot detection in a slot availability indication system via a user prompt;

flashing at least one disk availability light indicator disposed on a disk tray and logically associated via a RAID controller with one of at least one empty slots in three disk slots defined by said disk tray;

flashing three disk activity light indicators disposed on said disk tray and logically associated via said RAID controller with said three disk slots that include said at least one empty slot; and

flashing a RAID light indicator disposed on said RAID controller and logically associated with said three disk slots that include said at least one empty slot.
