2.2. DAE5000 (Full Fibre JBOD Disk Array Subsystems)
Discontinued: 31/10/2001.
2.2.1. Highlights
The DAE5000 Series constitutes a powerful, JBOD fibre channel storage solutions. It is based on a
DAE enclosure and contains up to 10 disks.
The direct access from servers to the Fibre Channel disks offers very high transfer rates, enabling to
operate near full Fibre Channel speed (around 95 MB/s), with a single DAE5000.
The DAE5000 is ideal to increase the storage capacity of AIX servers, without investing in more
expensive RAID subsystems. Use of AIX software RAID 1 brings protection against disk failures.
Protection against HBA, connection or DAE failures can be obtained using 2 DAE5000 per server.
The DAE5000 is also proposed as an entry range shared storage solution for dual node clusters, using
AIX mirroring and redundant DAE5000 for complete data protection.
2.2.2. Configurability and Packaging
The DAE5000 is based on DAE enclosures with a single LCC. A DAE5000 can host from 2 to 10
disks. Two DAE5000 can be connected per server.
There is no hardware option available for the DAE5000.

Series" earlier in this chapter.
