CHAPTER 6 Redundant Configuration
6.4
Redundancy of an HDD (Use of PRIMECLUSTER
GDS)
This section describes the redundant configuration for a HDD.
In the PRIMEQUEST series, an IO_Unit includes SCSI controllers, each of which has
its own system. Each SCSI controller connects to two HDDs. An IO_Unit has four
PCI cassette slots. The unit also has a PCI_Box interface to allow for PCI slot
expansion.
The I/O section does not have a redundancy function that would work independent
from without software. Therefore, to configure redundancy of the I/O function,
combine multiple I/O devices for the intended purpose and install the software
required to implement the redundancy function. Optional software is required for
redundancy.
Only Linux supports redundancy using optional software. Windows supports
mirroring using external RAID.
