2.1.1. Highlights
The DAS4500/5300/5700 and DAE 5000 Series storage subsystems constitute a powerful, highly
scalable, family of fibre channel storage solutions. They provide JBOD or RAID capabilities, terabytes
of disk storage capacity, high transfer rates, flexible configurations, and high availability. These
storage systems are ideal solutions for today's sophisticated enterprise.
The main customer benefits are:
•
high performance
•
scalability, modularity and flexibility
•
low foot print with capability to mix servers and storage in the same packaging (rack only)
•
capability to build high availability solutions, using multipath failover software and cluster
integration
•
sharing between heterogeneous servers
•
easy to use management tools
This line of disk subsystems is based on a common modular architecture, reusing the same components
across the complete range. These basic building blocks are:
disks
dual-ported fibre channel disks.
DAE enclosure
a 10 disk module, which can be chained to provide the
required capacity.
iDAE
Intelligent DAE, a DAE module with one or two RAID
Storage Processors (SP) designed for mid-range disk
DPE
a high end single or dual RAID Storage Processors with up to
10 disks.
