IBM DS6800 stores join expands the method of ark
From;    Author:Stand originally
Interior of IBM DS6800 memory can accommodate 16 fiber-optic dish, for example, 16 disk of 300GB, the capacity achieves 4.8TB. When the client needs larger space, can arrive through joining 13 patulous ark will expand additionally 224 disk, get the capacity of 67.2TB.

Cascade method is, road of the first annulus (annulus road of gray) join DS6800 in-house disk and additionally 6 disk are patulous ark, road of the 2nd annulus (annulus road of blue) join 7 disk expand ark.
Specific means is as follows:
1 . Road of the first annulus, the controller A of DS6800 has two lines to join the first disk expands the A interface of ark gets stuck, the controller B of DS6800 has two lines to join the first disk expands the B interface of ark gets stuck. The first disk expands the A interface card of ark has two lines to join the 2nd disk expands the A interface of ark gets stuck, the first disk expands the B interface card of ark has two lines to join the 2nd disk expands the B interface of ark gets stuck. Other dish next ark is ordinal connecting. Following graph place are shown.

2. Road of the 2nd annulus, the controller A of DS6800 and B controller have a line to join the first disk expands the A interface of ark gets stuck each, the controller A of DS6800 and B have a line to join the first disk expands the B interface of ark gets stuck each.
Such connective reasons are the A that every controller that lets DS6800 can control patulous ark and B two interface get stuck. Because road of the first annulus has inside buy dish, differ somewhat with the 2nd annulus so.
The first disk expands the A interface card of ark has two lines to join the 2nd disk expands the A interface of ark gets stuck, the first disk expands the B interface card of ark has two lines to join the 2nd disk expands the B interface of ark gets stuck. Other dish next ark is ordinal connecting. Following graph place are shown.
