Product Models Information
There are three different system configurations that are currently offered for both single (PRIORIS HX590) as
well as dual (PRIORIS HX590 DP) processor servers:
Base Systems are built around 16MB (single processor) or 32MB (dual processor) of parity RAM memory
and a Fast Wide (16-bit) SCSI host controller.
RAID Systems
are built around 16MB (single processor) parity DRAM memory and two 1GB Storage
Building Block (SBBs) with a narrow (8-bit) intelligent EISA SCSI RAID controller or 32MB (dual
processor) of Error Correction Code (ECC) DRAM memory and four 1GB Storage Building Block (SBBs)
with a narrow (8-bit) intelligent EISA SCSI RAID controller.
Kernel Systems
contain no SCSI controller and must be ordered with at least 16MB of DRAM memory.
With these systems either wide or narrow, non-RAID or RAID host controllers can be added. Kernel systems
may not be available in all territories.
The tables on the following pages provide details on these configurations:
