Sun Storedge 3900 And 6900 Series Common Features - Sun Microsystems StorEdge 3900 Series Reference And Service Manual

1.4.1 Sun StorEdge 3900 and 6900 Series Common
Features
The following are features available on both the Sun StorEdge 3900 and 6900 series:
Installation–The Sun StorEdge 3900 and 6900 series are delivered as storage
systems requiring minimum setup . The Sun StorEdge T3+ array logical units
(LUNs) are preconfigured at the factory.
RAID Striped Data with Standby Hot Spare–Internal Sun StorEdge T3+ array
LUNs are preconfigured as RAID 5 (eight drives, plus a standby hot spare).
Configuration tools are provided on the Storage Service Processor that enable the
internal configuration of the Sun StorEdge T3+ arrays to be changed to a limited
set of configurations. Preconfigured LUNs comprising 36-Gbyte disk drives are
236 Gbytes each, while preconfigured LUNs comprising 73-Gbyte disk drives
provide 477 Gbytes each, and preconfigured LUNs comprising 181-Gbyte disk
drives provide 506 Gbytes each.
Bandwidth–All of the storage subsystems use Fibre Channel technology to
provide the best available bandwidth. Current FC technology offers 1.06 Gbit per
second transfers (roughly 80 Mbytes per second average). The actual bandwidth
delivered might be less, depending on the configuration.
Capacity–The storage subsystems that have 36-Gbyte disk drives offer a
minimum of 648 Gbytes and a maximum of 1.9 to 5.8 Tbytes of disk space,
depending on the model selected. The subsystem has a footprint no larger than
12.29 square feet.
The storage subsystems that have 73-Gbyte disk drives offer a minimum of 1.3
Tbytes and a maximum of 3.9 to 11.7 Tbytes of disk space, depending on the
model selected. The subsystem has a footprint no larger than 12.29 square feet.
The storage subsystems that have 181-Gbyte disk drives offer a minimum of 3.2
Tbytes and a maximum of 9.7 to 29.3 Tbytes of disk space, depending on the
model selected. The subsystem has a footprint no larger than 12.29 square feet.
Data Path Redundancy–All of the storage subsystems provide full data path
redundancy with no data path component as a single point of failure, offering
24x7 data availability. Redundant components include the FC switches, Sun
StorEdge T3+ arrays, virtualization engines (on Sun StorEdge 6900 series only),
and dual power distribution units (PDUs).
Host Managed Multipathing–All of the storage subsystems present two physical
I/O paths to devices on each host. Host software is required to manage the I/O
utilization of the presented I/O paths. Such software includes, but is not limited
to, either Sun StorEdge Traffic Manager (MPxIO) software or VERITAS Dynamic
Multi-Pathing (DMP).
