Description |
|
|
|
| The Polywell Suma 12000FF/SAN utilizes the Mylex®
DACFF controller which delivers unparalleled performance and
is capable of sustaining disk transfer rates of up to 190 MB/sec
from servers to disk. The RAID controller has dual loop host
channels, providing redundant connections to give extra fault-tolerance
for high-data availability applications. The streamlined architecture
provides a separate memory for cache, cache look-up tables,
and the CPU instruction store to eliminate bus contention for
optimum throughput. The Suma 12000FF/SAN also has four Fibre
Channel loops for drive connections. These four channels can
also be configured as independent loops to maximize disk connectivity
or as two redundant loops for increased availability. |
