EXPANSION
Expansion of multi-queue devices is also possible, up to 8 devices can be
connected in a parallel fashion providing the possibility of both depth expansion
or queue expansion. Depth Expansion means expanding the depths of
individual queues. Queue expansion means increasing the total number of
queues available. Depth expansion is possible by virtue of the fact that more
memory blocks within a multi-queue device can be allocated to increase the
depth of a queue. For example, depth expansion of 8 devices provides the
possibility of 8 queues of 64K x36 deep, each queue being setup within a single
device utilizing all memory blocks available to produce a single queue. This is
the deepest queue that can setup within a device.
For queue expansion of the 4 queue device, a maximumnumber of 32 (8
x 4) queues may be setup, each queue being 2K x36 deep, if less queues are
setup, then more memory blocks will be available to increase queue depths if
desired. When connecting multi-queue devices in expansion mode all respec-
tive input pins (data & control) and output pins (data & flags), should be
“connected” together between individual devices.
