Overview
This guide provides information about initial hardware setup for the AssuredSAN™ 4004 Series storage
enclosure products listed below:
• CNC (Converged Network Controller) controller enclosure (4824/4834/4844/4854 models):
• Qualified Fibre Channel SFP option supporting (4/8/16 Gb)
• Qualified Internet SCSI (10GbE) SFP option
• Qualified Internet SCSI (1 Gb) Copper RJ-45 SFP option
• HD mini-SAS (12 Gb) controller enclosure: 4524/4534/4544/4554
In general, AssuredSAN 4004 Series enclosures are designed to meet NEBS Level 3, MIL-STD-810G
(storage requirements), and European Telco requirements. The 4004 Series supports both a large form
factor (LFF 12-disk) 2U chassis and a small form factor (SFF 24-disk) 2U chassis. The 4004 Series also
supports high-density storage in 2U (SFF 48-disk) and 4U (LFF 56-disk) chassis. All chassis form factors
support configuration as either a controller enclosure or an expansion enclosure. Controller enclosures can
optionally be cabled to supported drive enclosures for adding storage.
Notable differences between configuration of 4004 Series chassis form factors are listed:
• 2U24 and 2U12 storage enclosures can be configured with either single or dual I/O modules
(IOMs) and either two redundant AC or DC power supply modules.
• 2U48 storage enclosures are configured with dual-IOMs and two redundant AC power supply
modules. Unlike other 4004 Series enclosures, the 2U48 is not designed for NEBS compliance.
• 4U56 storage enclosures are configured with dual-IOMs and either two redundant AC or DC power
supply modules.
IMPORTANT: The 2U48 and 4U56 enclosures provide single-controller support only when a
controller fails over to its partner controller.
TIP: Comparative information pertaining to these 4004 Series chassis form factors is provided in
Table 4 on page 39 and Table 5 on page 41.

AssuredSAN 4004 Series enclosures support both traditional linear storage and virtual storage, which uses
paged-storage technology. For linear storage, a group of disks with an assigned RAID level is called a
vdisk or linear disk group. For virtual storage, a group of disks with an assigned RAID level is called a
virtual disk group. This guide uses the term vdisk when specifically referring to linear storage, and uses the
term disk group otherwise.
AssuredSAN 4004 Series enclosure user interfaces
The 4004 Series enclosures support two versions of the web-based application for configuring, monitoring,
and managing the storage system. Both web-based application GUI versions (v3 and v2), and the
command-line interface are briefly described:
• Storage Management Console (SMC) is the primary web interface (v3) to manage virtual storage.
• RAIDar is a secondary web interface (v2) to manage linear storage. This legacy interface provides
certain functionality that is not available in the primary interface.
• The command-line interface (CLI) enables you to interact with the storage system using command syntax
entered via the keyboard or scripting. You can set a CLI preference to use v3 commands to manage
virtual storage or to use v2 commands to manage linear storage.
