About this guideOverview

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.

See the Dot Hill web site for more information about specific storage product models and uses: https://www.dothill.com.

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 interfacesThe 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.

NOTE: For more information about enclosure user interfaces, see the following:• AssuredSAN Storage Management Guide or online help

The guide describes SMC (v3) and RAIDar (v2) GUIs• AssuredSAN CLI Reference Guide

CNC ports used for host connectionAssuredSAN 4824/4834/4844/4854 models use Converged Network Controller (CNC) technology, allowing you to select the desired host interface protocol from the available Fibre Channel (FC) or Internet SCSI (iSCSI) host interface protocols supported by the system. You can use the CLI to set all controller module CNC ports to use one of these host interface protocols:

• 16 Gb FC• 8 Gb FC• 4 Gb FC• 10 GbE iSCSI • 1 GbE iSCSI

Alternatively, you can use the CLI to set CNC ports to support a combination of host interface protocols. When configuring a combination of host interface protocols, host ports 0 and 1 are set to FC (either both16 Gbit/s or both 8 Gbit/s), and host ports 2 and 3 must be set to iSCSI (either both 10GbE or both 1 Gbit/s), provided the CNC ports use the qualified SFP connectors and cables required for supporting the selected host interface protocol. See CNC technology on page 58 and 4824/4834/4844/4854 CNC controller module — rear panel LEDs on page 122 for more information.

TIP: See the Storage Management Guide for information about configuring CNC ports with host interface protocols of the same type or a combination of types.

IMPORTANT: AssuredSAN 4824/4834/4844/4854 models ship with CNC ports initially configured for FC. When connecting CNC ports to iSCSI hosts, you must use the CLI (not the SMC or RAIDar) to specify which ports will use iSCSI. It is best to do this before inserting the iSCSI SFPs into the CNC ports (see Change the CNC port mode on page 78 for instructions).

HD mini-SAS ports used for host connectionAssuredSAN 4524/4534/4544/4554 models provide four high-density mini-SAS (HD mini-SAS) ports per controller module. The HD mini-SAS host interface protocol uses the SFF-8644 external connector interface defined for SAS3.0 to support a link rate of 12 Gbit/s using the qualified connectors and cable options. See 4524/4534/4544/4554 SAS controller module—rear panel LEDs on page 124 for more information.

Your 2U48 enclosure is shipped with the drawers installed, but they are not populated with disks. Depending on your product configuration, disk bay blanks—also known as Air Management Solution (AMS) inserts—might be installed. Locate the box containing your sledded disks and AMS inserts (if applicable) in preparation for populating the drive slots.

• See Table 3 on page 28 for sequential tasks required for successful enclosure installation.• See Populating drawers in 2U48 enclosures on page 29 for instructions on installing disks and AMS

inserts.

IMPORTANT: Disk drive slot numbering is also provided on the label attached to the sheet metal housing (top face) on each drawer. Refer to the drawer label when installing disks into the drawer.

Figure 5 below provides a sample partial configuration of disk bays within a drawer. The bay on the left is populated with four disks, whereas the adjacent bay on the right contains an AMS insert to manage air flow within the enclosure to maintain optimal operating temperature.

1The disk is oriented in the sled such that its PCBA faces upward on the top side of the disk drive module as shown.2Electromagnetic interference protection is provided by the EMI shield within the enclosure bezel.3The AMS insert spans an entire disk bay (4 slots). A single disk slot AMS is also available.

Figure 5 2U48 enclosure: sample drawer population

IMPORTANT: Empty bays will cause overheating. To avoid overheating, install an AMS insert in disk bays that do not contain quantity four disk drive modules.• Legacy models use the disk bay AMS insert shown above (spans four disk slots).• Newer models use the single disk slot AMS insert (see Figure 24 on page 31).

Controller enclosure — rear panel layout2U48/2U24/2U12 controller enclosures

The diagram and table below display and identify important component items that comprise the rear panel layout of a 2U form factor AssuredSAN 4004 Series controller enclosure. The 4824/4834 is shown as a representative example of controller enclosure models included in the product series. The rear panel layout generally applies to the 2U48, 2U24, and 2U12 form factors. Notable differences are listed:

• Whereas the AC power supplies used in 2U24 and 2U12 enclosures are not equipped with a power switch, the AC power supply used in 2U48 enclosures provides a power switch.

• Whereas the 2U24 and 2U12 enclosures can be configured with redundant AC power supplies or redundant DC power supplies, the 2U48 enclosure supports redundant AC power supplies exclusively.

• Whereas the 2U24 and 2U12 enclosures support single and dual-IOM configuration, the 2U48 enclosure supports dual-IOM configuration exclusively. Single controller support is provided only when a controller fails over to its partner controller on 2U48 enclosures.

Figure 10 4004 Series controller enclosure: rear panel (2U)

A controller enclosure accommodates two power supply FRUs of the same type within the two power supply slots (see two instances of callout No.1 above). The DC option is not applicable for the high-capacity 2U48 chassis. The controller enclosure accommodates up to two controller module FRUs of the same type within the I/O module (IOM) slots (see callouts No.2 and No.3 above).

IMPORTANT: If the 4004 Series 2U24 or 2U12 enclosure is configured with a single IOM, the IOM must be installed in the upper slot (see callout No.2 above), and an I/O module blank must be installed in the lower slot (see callout No.3 above). This configuration is required to allow sufficient air flow through the enclosure during operation.

IMPORTANT: 2U48 controller enclosures support dual-controller configuration only. Single-controller support is provided only when a controller fails over to its partner controller. A controller module must be installed in each IOM slot to ensure sufficient air flow through the enclosure during operation.

The diagrams with tables that immediately follow provide descriptions for the different controller modules and power supply modules that can be installed into the rear panel of a 4004 Series controller enclosure. Showing controller modules and power supply modules separately from the enclosure enables improved clarity in identifying the component items called out in the diagrams and described in the tables.

Descriptions are also provided for optional drive enclosures supported by 4004 Series controller enclosures for expanding storage capacity.

NOTE: 4004 Series enclosures support hot-plug replacement of redundant controller modules, fans, power supplies, and expansion modules. Hot-add replacement of drive enclosures is also supported.

26 Components

CacheTo enable faster data access from disk storage, the following types of caching are performed:

• Write-back or write-through caching. The controller writes user data into the cache memory in the controller module rather than directly to the disks. Later, when the storage system is either idle or aging —and continuing to receive new I/O data—the controller writes the data to the disks.

• Read-ahead caching. The controller detects sequential data access, reads ahead into the next sequence of data—based upon settings—and stores the data in the read-ahead cache. Then, if the next read access is for cached data, the controller immediately loads the data into the system memory, avoiding the latency of a disk access.

TIP: See the Storage Management Guide for more information about cache options and settings.

CompactFlashDuring a power loss or controller failure, data stored in cache is saved off to non-volatile memory (CompactFlash). The data is restored to cache, and then written to disk after the issue is corrected. To protect against writing incomplete data to disk, the image stored on the CompactFlash is verified before committing to disk.

The CompactFlash memory card is located at the midplane-facing end of the controller module as shown below. Do not remove the card; it is used for cache recovery only.

Figure 17 CompactFlash memory card

In single-controller configurations (supported with 2U24/2U12 chassis), if the controller has failed or does not start, and the Cache Status LED is on or blinking, the CompactFlash will need to be transported to a replacement controller to recover data not flushed to disk (see Controller failure in a single-controller configuration on page 89 for more information).

Do not remove

Used for cache recovery only

Controller module pictorial

CompactFlash memory card

(Midplane-facing rear view)

Host interfaceUSB - Type A(shown covered)


CAUTION: The CompactFlash memory card should only be removed for transportable purposes. To preserve the existing data stored in the CompactFlash, you must transport the CompactFlash from the failed controller to the replacement controller using a procedure outlined in AssuredSAN 4004 Series FRU Installation and Replacement Guide within the procedure for replacing a controller module. Failure to use this procedure will result in the loss of data stored in the cache module. The CompactFlash must stay with the same enclosure. If the CompactFlash is used/installed in a different enclosure, data loss/data corruption will occur.

IMPORTANT: In dual-controller configurations featuring one healthy partner controller, there is no need to transport failed controller cache to a replacement controller because the cache is duplicated between the controllers (subject to volume write optimization setting).

Supercapacitor packTo protect controller module cache in case of power failure, each controller enclosure model is equipped with supercapacitor technology, in conjunction with CompactFlash memory, built into each controller module to provide extended cache memory backup time. The supercapacitor pack provides energy for backing up unwritten data in the write cache to the CompactFlash, in the event of a power failure. Unwritten data in CompactFlash memory is automatically committed to disk media when power is restored. In the event of power failure, while cache is maintained by the supercapacitor pack, the Cache Status LED flashes at a rate of 1/10 second on and 9/10 second off.

28 Installing the enclosures

2 Installing the enclosuresInstallation checklist

The following table outlines the steps required to install the enclosures, and initially configure and provision the storage system. To ensure successful installation, perform the tasks in the order presented.

IMPORTANT: For 4U56 enclosures, retain original packaging materials for use with returns. For chassis returns, the master container must ship on a pallet (non-compliance could void warranty).

1The 2U12 and 2U24 enclosures ship with pre-installed disks; whereas the 2U48 and 4U56 enclosures do not.2See the AssuredSAN 4004 Series FRU Installation and Replacement Guide for illustrations and narrative describing attachment of

enclosure bezels to chassis. See also Enclosure bezel attachment and removal on page 104. The 2U12 and 4U56 chassis include hard copy shipkit instructions describing enclosure bezel attachment and removal, and servicing of the air filter.
