Preface
Thank you for your interest in Dell™ EqualLogic™ PS Series storage products. We hope you will find them
intuitive and simple to configure and manage.
PS Series arrays optimize resources by automating volume and network load balancing. Additionally, PS
Series arrays offer all-inclusive array management software, host software, and firmware updates. The
features and products described next are available as part of the all-inclusive software package and are at
no additional cost.
PS Series Software
– Firmware: Installed on each array, PS Series firmware software allows you to manage your storage
environment and provides capabilities such as volume snapshots, cloning, and replication to ensure
data hosted on the arrays is protected in the event of an error or disaster.
– Group Manager GUI: Provides a graphical user interface for managing a group.
– Group Manager CLI: Provides a command line interface for managing a group.
– Manual Transfer Utility (MTU): Runs on Windows and Linux systems and enables you to use physical
media to securely transfer large amounts of data to a replication partner, facilitating replication and
preventing network congestion.
– SAN Headquarters (SANHQ): Provides centralized monitoring, historical performance trending, and
event reporting for multiple PS Series groups.
Host Software for Linux
– Remote Setup Wizard Command Line Interface (RSWCLI): Discovers and initializes PS Series arrays,
configures and manages access to PS Series arrays, and configures and manages multipathing.
– Multipath device configuration components: Provides the EqualLogic Connection Manager (ehcmd)
daemon to manage multipath devices, a Device Mapper kernel module (dm-switch) to optimize routing
of multipathing devices, and a command line interface (ehcmcli) that allows users to review the
diagnostic state of EqualLogic multipathing.
– EqualLogic Host Performance and Tuning Tool Suite (eqltune), a utility used to validate configurable
parameters against practices recommended by Dell.
Host Software for Windows®
– Remote Setup Wizard (RSW): Initializes new PS Series arrays, configures host connections to PS Series
groups, and configures and manages multipathing.
– Remote Setup Wizard Command Line Interface (RSWCLI): Provides a command-line alternative to the
Remote Setup Wizard.
– Multipath I/O Device Specific Module (MPIO DSM): Includes a connection awareness module that
understands PS Series network load balancing and facilitates host connections to PS Series volumes.
– VSS and VDS Provider Services: Allows 3rd party backup software vendors to perform off-host backups.
– Auto-Snapshot Manager/Microsoft Edition (ASM/ME): VSS Requestor interface that uses PS Series
snapshots, cloning, and replication to provide point-in-time application-consistent protection of critical
data for supported applications (including SQL Server, Exchange Server, Hyper-V, and NTFS file shares).
– PowerShell Tools: Provides a comprehensive set of PowerShell cmdlets for managing one or many PS
Series groups.
