Introduction
This hardware manual briefly introduces the EonStor (ES) U16U-G4010 (ES U16U)
SCSI-to-SCSI storage subsystems shown in
Figure 1-1
.
Figure 1-1: ES U16U storage subsystem
The ES U16U subsystem series comes in four models (see
Table 1-1
). All the models
come with two 320MB/sec SCSI (SCSI-320) host channels and are able to support up to
16, hot-swappable, SCSI-320 hard drives. Two hot-swappable cooling fan modules
protects the subsystem from over heating and two, hot-swappable power supply unit
(PSU) modules provide a constant power supply to the subsystem. The modular nature of
the subsystem and the easy accessibility to all major subsystem components ensures that
the ES U16U can be easily maintained.
1.2.2 Model
Variations
The SCSI-320 ES U16U subsystems come in four different models. Two models come
with four SCSI-320 (two host and two drive) channels and two models come with six
SCSI-320 (two host, two expansion and two drive) channels. The host IO board (see
Section 1.5.1.3
) on the six channel models comes with an additional two pre-set, SCSI-
320 drive channels that are connected to external expansion connectors. These additional
expansion channels are facilitated by the presence of an additional chip on the host IO
board itself.
One four channel model and one six channel model comes with a 256MB pre-installed
DIMM module whereas the other two models (one four channel and one six channel)
come with a 512MB DIMM module. (See
Section 1.5.1.2
)
