The DS6000™ series
is built upon 2 Gbps fibre-channel technology that can help bring high availability
RAID-protected storage with scalable capacity, increased addressing capabilities,
and connectivity to a wide range of storage area network (SAN) applications.
The DS6000 series
provides the following technology and hardware to meet today's on demand business
environments:
- Integrated RAID controller technology
- The DS6000 series
features IBM's 32-bit PowerPC microprocessor, a fourth generation processing
technology.
- High availability
- The DS6000 series
is designed with component redundancy to eliminate single points of hardware
failure, and no single point of repair other than the enclosure.
- Industry standard fibre-channel disk drives
- The DS6000 series
offers a selection of 2 GB fibre-channel disk drives, including 300 GB drives, and 500 GB, 7200 rpm fibre-channel
ATA (FATA) disk drives, which allow the DS6000 series
to scale up to a capacity of 64 TB.
- Parallel Access Volumes
- Parallel Access Volumes (PAV) can provide significant performance enhancements
in zSeries environments by enabling simultaneous processing for multiple I/O
operations to the same logical volume, which can help to significantly reduce
device queue delays. This is achieved by defining multiple addresses per volume.
With Dynamic PAV, the assignment of addresses to volumes can be automatically
managed to help the workload meet its performance objectives and reduce overall
queuing. PAV is an optional feature for the DS6000 series
and also requires the purchase of the FICON Attachment feature.
- LUN and volume management
- LUN and volume creation and deletion is nondisruptive. When you delete
a LUN or volume, the capacity can immediately be reused. You can configure
LUN and volumes to span arrays, which allows larger LUNs and volumes.
- Addressing capabilities
- The DS6000 series
allows the following:
- Up to 32 logical subsystems
- Up to 8192 logical volumes
- Up to 1040 volume groups
- Simplified storage management for zSeries with z/OS
- The DS6000 series
supports a new 65 520 cylinder 3390 volume. This volume option has a capacity
of approximately 55.7 GB. It helps relieve addressing constraints, improve
disk resource use, and improve storage administrator productivity by providing
the ability to consolidate multiple disk volumes into a single address.
- System management
- The DS6000 series
provides online and offline configuration capability features and a graphical
user interface (GUI) that is designed to offer increased ease of use.
A
single command line interface (CLI) supports both logical configuration and
copy services.
- Online Information Center
- The online Information Center is an information database that provides
the opportunity to quickly familiarize yourself with the major aspects of
the DS6000 series
and to easily recognize the topics for which you might require more information.
It provides information regarding user assistance for tasks, concepts, reference,
user scenarios, tutorials, and other types of user information. Because the
information is all in one place rather than across multiple publications,
you can access the information that you need more efficiently and effectively.
