Examples of Use for Fibre Channel
The following only applies to PCI nodes (EPC400/430/440, EPC1200, EPC1200A and
EPC2400) with the Clariion DAS fibre models. This includes DAS 3500, DAS 57xx.
DAS5300 (DPE) and its associated DAE.
Thre are four types of Clariion storage systems available in a rackmount version.
• DAS5700: 10 to 120 disks RAID subsystems. A DAS5700 includes one DPE and
additional DAEs. Disk-Array Processor Enclosure (DPE) based storage systems –
storage processor building blocks for high availability and performance expansion –
13,200 I/Os per second and 167MB per second. A DPE is a 10-slot enclosure with RAID
functionality provided by one or two storage processors (SPs). In addition to its own
disks, a DPE can support additional disks in chained 10-slot Disk-Array Enclosures
(DAEs).

• DAS5300: low end 10 to 30 disks RAID subsystems. A DAS5300 includes one DPE and
up two additional DAEs.
• DAS 3500 is a 30-slot SCSI disk storage system. Like the DPE, these offer RAID
functionality provided by one or two SPs. However, they use SCSI, not Fibre Channel,
disk. Each has space for 30 modules.

• DAS 3500 and DPE have complete RAID level support – RAID 1/0, 1, 3 and 5.
• Disk-Array Enclosure (DAE-only) storage systems. A DAE is a 10-slot enclosure without
SPs (otherwise known as Just a Bunch Of Disks – JBOD). A DAE-only system does not
inherently include RAID but can operate as a RAID device using software running on the
server system.
