Server models and brings unique high-end capabilities to the 3PAR midrange F-Class InServ
Storage Servers. Persistence Cache is available as part of InForm OS.

RAID MP is a Fast RAID 6 technology, accelerated by the 3PAR Gen3 ASIC, and serves as extra

2.5.4 Automation/Manageability to Eliminate Repetitive and Error-Prone
Administrative Tasks
2.5.4.1 Autonomic Groups
Autonomic groups simplify the administration task of managing and provisioning storage
especially in clustered environments where the large number of provisioning commands can
cause significant overhead and administration cost. Autonomic groups enables grouping of
hosts, volumes, and virtual domains, and significantly reduces administration costs. Autonomic
Groups is available as part of InForm OS.
2.5.4.2 Host Explorer
Host Explorer enables gathering host configuration and transferring the information
automatically to 3PAR Central. The Host Explorer runs as a service on Windows and as a
daemon on Linux and Solaris operating systems. Host Explorer enables automated creation of
Hosts on the InServ Storage Server. Host Explorer is separately orderable software.
2.5.4.3 Scheduler
The scheduler helps automate the creation and deletion of snapshots (Virtual Copies) by
scheduling InForm CLI commands to execute at a pre-determined time. This scheduling facility
allows for automatic creation and deletion of snapshots, thereby freeing storage
administrators from manual and time consuming tasks. Scheduler is supported only in the CLI.
Scheduler is available as part of InForm OS.
