2.1.5. DPE Enclosure
2.1.5.1. Overview
The
DPE
(Disk-Array Processor Enclosure) is a 10-slots enclosure with RAID functionality provided
by one or two SPs (Storage Processors). It has been designed to build high-end disk subsystems, with
up to 100 disks. It is a “full Fibre Channel” RAID subsystem, using Fibre Channel for both host
connect (i.e. front-end) and internal disks connection (i.e. back-end).
Configurations can be defined with the minimum of hardware redundancy, to enable cost attractive
solutions with high end SPs. Upgrade to a fully redundant high availability configuration is a simple
matter of adding redundant hardware components (described below). All these components are
designed for non-disruptive removal and insertion, and can be replaced under power.
The DPE can host various SPs:
•
4500, the latest generation of SP, delivers the highest performance levels and can connect to
heterogeneous servers (in conjunction with Access Logix). The 4500 supports sharing between
multiple operating systems.
•
5700, the second generation of SP. The 5700 supports sharing between AIX and NT servers, when
used in conjunction with ASM (AIX SAN Manager) or [e-mail]!.
