Storage Service Processor; Virtualization Engines - Sun Microsystems StorEdge 3900 Series Reference And Service Manual

2.1.1

Storage Service Processor

The Storage Service Processor is delivered as part of the Sun StorEdge 3900 and 6900
series. The Storage Service processor can be either of the following:
The Sun Fire™ V100 server. The Sun Fire provides a 500-MHz, 64-bit
UltraSPARC
and a CD-ROM drive.
The Sun Netra™ X1 server. The Netra provides a 500-MHz, 64-bit UltraSPARC
processor, 512 Mbytes of memory, and a 40-Gbyte IDE internal drive.
The Storage Service Processor is responsible for the following functions:
Monitor the components in the Sun StorEdge 3900 and 6900 series
Fault isolation, verification, and notification of a FRU that is failing
Configuration of the Sun StorEdge T3+ array partner groups, virtualization
engine, and Fibre Channel switches
Serve as the service portal to all components in the Sun StorEdge 3900 or 6900
series
Every Storage Service Processor is configured with the same hardware and software
components to ensure ease of replacement. All Storage Service Processors can
support the Sun StorEdge Remote Response option if the necessary hardware and
software are added.
Any single Storage Service Processor can become the collection point for other
geographically local Storage Service Processors; this is referred to as the master
Storage Service Processor.
2.1.2

Virtualization Engines

The virtualization engines are a pair of routers used to build a SAN environment for
the Sun StorEdge 6900 series. The Sun StorEdge 6910 and 6910SL systems have one
pair of virtualization engines, while the Sun StorEdge 6960 and 6960SL systems have
two pairs.
The virtualization engine provides the following functions:
LUN carving (creating smaller virtual drives from physical LUNs)
LUN masking, which restricts access by the host HBA to the virtual LUNs
The virtualization engine supports the multipathing functionality of the Sun
StorEdge T3+ arrays. That is, each unit in the Sun StorEdge 6910 or 6910SL system
provides physical access to all of the underlying Sun StorEdge T3+ arrays. Each
