(If necessary) Set the spin-up options for the disk drives. Normally the
default settings configure the spin-up option to spin the drives up upon
power on conditions. However, you may require a specific and different
configuration for the drive spin-up option. Refer to the table below for the
appropriate settings for spin-up options.
This concludes the overview of setting the SES Controller card switches. Continue
on the next page with configuring and cabling the selected operating mode. You
will be instructed at the appropriate time to set the switches as described here.
Simplex Mode (NexStor 4210F)
The basic simplex (Stand-Alone) operating mode provides a single enclosure with
a single RAID Controller solution. It has provisions for drive channel expansion
capabilities through daisy-chaining of JBOD enclosures, the NexStor 4000F, and
upgrading to a NexStor 4220F model by adding an additional controller for duplex
operations. This mode provides solutions for single or multiple host environments
that require a low cost fault-tolerant disk storage solution.
CAUTION:
The bus speed must be set to the same setting between the disk
drives and the Disk I/O card(s), and then the host system HBAs
(BIOS setting) and the Host I/O cards. For example, if you are using
2 Gb drives, the Disk I/O cards must be set to 2 Gb mode. If your
host system HBA(s) is set to 1 Gb mode, the Host I/O card(s) must
be set to 1 Gb mode.
NOTE: Split-bus mode is not supported when a RAID Controller is installed.
