1Introduction
The functionality, mechanics and design of the PRIMERGY SX30 storage
subsystem are optimally adapted to the PRIMERGY servers. It can be used as
rack or floorstand model. In the 19-inch rack, the SX30 subsystem occupies
three height units.
The PRIMERGY SX30 storage subsystem can accommodate up to fourteen
1-inch hard disk drives. If it is equipped, e. g. with 146 Gbyte Ultra 160/320 SCSI
drives, approximately 2 Tbyte hard disk memory is available as a maximum
within one housing.
The PRIMERGY SX30 exists in a single-node, as well as in a dual-node version.
Whereas the one-channel option (1 x 14 HDD) and the two-channel option (2 x
7 HDD) are both available for the single-node version, there is only the twochannel option for the dual-node (cluster) version.
The cluster capability is made possible by the use of dual node SCSI modules.
In conjunction with the Microsoft Windows 2000 Advanced Server, two
PRIMERGY servers can be run over two channels on a two-channel
PRIMERGY SX30 storage subsystem via one RAID controller each. As a result
of the dual node SCSI module, both servers are connected to each SCSI
channel in the storage subsystem.
Server Management/ServerView
ServerView uses the SAF-TE protocol of the SCSI bus to communicate with the
clients.
ServerView and the related agents are set up within the group of servers and
storage subsystems being monitored. The received informations are evaluated
by ServerView and processed for display or forwarding to the administrator
(manager).
I When installing PRIMERGY SX30 Storage Subsystems in connection
with ServerView please install the ServerStart CD version 3.29 or higher
on each of the connected servers.
Notes to installing and update see at the documentation of ServerView (see
also “Related publications” on page 93).

Position Function Description
(I) local ON The storage subsystem is switched on permanently
and is connected directly to the mains (for test
purposes only).
(R) remote ONThe operating mode (ON/OFF) is controlled by
TERMPWR via at least one of the SCSI buses or the
service processor module. In this default setting, the
storage subsystem is switched ON and OFF simultaneously with the server. If two servers are connected,
it remains active as long as one of the servers is
switched ON.
(O) OFF The storage subsystem is switched OFF permanently.
