Introduction
This guide provides information about initial hardware setup, and removal and installation of customer-replaceable
units (CRUs) for the Lenovo ThinkSystem™ DS6200/DS4200/DS2200 controller enclosures, as well as the DS
Series Exp Unit (DS EXP) and D3284 expansion enclosures
In controller enclosures, controller modules can be purchased with either of two types of host interface: SAS or
FC/iSCSI. An FC/iSCSI controller module's host ports use converged network adapters, and is informally referred
to as a converged network controller (CNC):
•
FC/iSCSI controller enclosure:
Qualified Fibre Channel SFP option supporting (8/16Gb)
Qualified Internet SCSI (10GbE) SFP option
Qualified Internet SCSI (1Gb) Copper RJ-45 SFP option
•
SAS (12Gb) controller enclosure
The DS6200, DS4200, and DS2200 are SBB-compliant (Storage Bridge Bay) enclosures. These enclosures support
large form factor disks or small form factor disks in 2U12, 2U24, and 5U84 chassis. These 2U chassis form factors
support controller enclosures and expansion enclosures.
The DS Series controller enclosures can optionally be cabled to supported DS EXP/D3284 expansion enclosures
for adding storage. See also
maximum configuration information.
IMPORTANT: Product configuration characteristics for controller and optional expansion enclosures:
•
DS6200/DS4200/DS2200 and optional DS EXP products use the same 2U24 and 2U12 chassis form factors.
•
DS6200 is only available in the 2U24 chassis.
•
DS6200 and DS4200 provide four host ports per controller I/O module (SBB RAID canister).
•
DS2200 provides two host ports per controller I/O module.
•
DS6200/DS4200/DS2200 models are configured with two controller modules per enclosure.
•
Optional DS EXP 2U models are configured with two expansion I/O modules (SBB expansion canisters) per
enclosure.
•
Optional D3284 5U models are configured with two expansion I/O modules, and hold up to 84 disk drives.
•
Optional D3284 5U model is an expansion enclosure supporting DS6200 and DS4200 (not supported by
DS2200). This high-density chassis is not configured or used as a controller enclosure.
Lenovo ThinkSystem enclosures support virtual storage, which uses paged-storage technology. For virtual storage,
a group of disks with an assigned RAID level is called a disk group.
DS6200/DS4200/DS2200 enclosure user interfaces
The DS6200/DS4200/DS2200 enclosures support applications for configuring, monitoring, and managing the
storage system. The web-based application GUI and the command-line interface are briefly described:
•
Storage Management Console (SMC) is the web interface for the enclosure, providing access to all common
management functions for virtual storage.
•
The command-line interface (CLI) enables you to interact with the storage system using command syntax
entered via the keyboard or scripting.
