2.2.3. SAN Features
Each DAE5000 is connected to a dedicated fibre channel adapter on the AIX server, or to a hub for
sharing by 2 servers. Interconnection of DAE5000 is not proposed, due to the high performance
obtained with the 10-disk enclosure, and the risk of saturation of the fibre channel loop.
The connection to hubs or servers is made with copper cables. Connection to switches has not been
qualified.
2.3. DAS5300 (Full Fibre RAID Disk Subsystems)
CABG024/CABG026/DRWG010 Discontinued : December 31, 2003
2.3.1. Highlights
The DAS5300 constitutes an entry-level RAID subsystem, offering up to 30 disks (18 / 36 / 72 GB). It
is based on iDAE and DAE enclosures. The Fibre Channel technology used for the host connection
brings an optimal cabling flexibility, and high transfer rates (up to 120 MB/s with dual SP).
The basic packaging, containing 1 SP, and a single power supply, can be upgraded with optional
hardware to offer a fully redundant disk subsystem. Several packaging and capacity options allow to
build the most suited configuration, while preserving the evolutivity up to 30 disks.
The DAS5300 offers an excellent data protection solution for use with standalone servers, or as a
shared storage between multiple AIX servers and/or cluster nodes.
The DAS 5300 can be shared by AIX and NT servers, using ASM (AIX SAN Manager) or S@N.IT!.
