Each solution is designed to be easy to deploy, secure, and reduce management costs, while driving rapid return on investment.

Modular Smart Array 20

The HP StorageWorks Modular Smart Array 20 Enclosure (hereafter referred to as "MSA20") is a SATA 1.5Gb/s disk drive storage enclosure with Ultra320 SCSI host connectivity. These enclosures deliver industry-leading availability, storage density, and upgradeability to meet customers' demanding and growing storage needs. The MSA20 delivers the ideal mix of low-cost and high capacity, for minimum I/O workloads such as reference data, archival, and disk-to-disk backup.

Key Features

Serial-ATA 3G - Delivering data transfer rates greater than 100MB/s Ultra320 (LVD) host support - Delivering compatibility with 6th generation Smart Array controllers 2U rack height A common storage platform allows for future storage consolidation to the SAN Hot pluggable disk drives, power supplies, and fans Redundant fans, and redundant power supplies Each MSA20 enclosure comes with dual power supplies that are sufficient to provide power to the enclosure and maintain normal operating levels. Integrated Environmental Monitoring - Monitors environmental conditions within the enclosure and components such as the power supply and fans Easy removal of parts provides better serviceability. No tools are required! Provides storage capacity of up to 12TB per enclosure (using 1TB SATA disk drives). Modular design allows up to 21 enclosures to be mounted in one 42U rack for a single rack storage capacity of up to 189TB of disk storage or up to 8 enclosures in an MSA1500 or a MSA1510i configuration for storage capacity of 64-TB in an entry-level SAN. NOTE: The MSA20 had an onboard controller module. When the MSA20 is directly attached to a ProLiant server with a Smart Array controller, the MSA20 controller module functions as the array controller and the Smart Array Controller acts as the Host Adapter. When the MSA20 is connected to a MSA1500 controller shelf, the MSA1500 or MSA1510i controller functions as the array controller and present the MSA20 as a JBOD. NOTE: When using 750 GB or higher SATA HDD behind a MSA1500 or a MSA1510i, the maximum capacity available is 64 TB, maximum available storage capacity depends on the RAID level being implemented, and is based on maximum number of LUNs (32) and maximum LUN size (2 TB). Support for 750 GB or higher SATA requires minimum firmware V 5.20 on MSA1500 and V1.32 on MSA1510i and V2.02 on MSA20. NOTE: 3G SATA drives will only function as 1.5G drives in a MSA20

Product Highlights
High Levels of Storage Density, Data Protection, and Functionality
Storage Capacity - The Modular Smart Array 20 cabinet supports up to twelve SATA 3G hard drives, for a maximum of 12 TB of storage capacity using HP 1TB SATA 3G 3.5" hard drives. (3G SATA drives will only function as 1.5G drives in a MSA20) Data Protection - Modular Smart Array 20 is designed for a high level of data protection. It includes redundant fans and power supplies (standard), battery-backed cache, and support for various RAID level including RAID ADG (RAID ADG within the enclosure only applies when connected to a SA6402 or SA6404, controller. When connected to a MSA1500 the RAID ADG function is performed in the MSA1500 controller.) Storage Manageability - The Smart Array 20 feature familiar configuration and management tools such as Smart Array Configuration Utility and Insight Manager. Online Management Features: Online Capacity Expansion, Online RAID Level Migration, Online Stripe Size Migration, Online Spares (Global), User Selectable Read/Write cache, User Selectable Expand and Rebuild Priority. (These features are available only when connected to a SA6402, SA642 and 6i controller.) Choice of Computing Platform - The Modular Smart Array 20 is designed and qualified for ProLiant servers. Advanced Data Guarding (RAID 6 with ADG) Fault Tolerance - This is the highest level of RAID fault tolerance. It allocates two sets of parity data across drives and allows simultaneous write operations. This level of fault tolerance can withstand two simultaneous drive failures without downtime or data loss. (Only available when NOT connected to a MSA1500.)
Low Total Cost of Ownership
The modular, scalable design of the Modular Smart Array 20 provides an extremely flexible platform. You can buy what you need today and purchase additional capacity as your data storage needs grow, instead of making a large up-front investment. Additional drives and enclosures can be easily added as your needs dictate. Tiered Storage Improve storage utilization and lower storage management cost by moving lowIO storage applications to the Modular Smart Array 20 allowing you to more effectively utilize mission critical storage where you need it most. Universal SATA Hard Drive Since the Modular Smart Array 20 supports HP Universal SATA drives, your investment in disk drives is protected and cost is minimized as you add new drives. Sharing of a common universal drive form factor between your server and storage can significantly reduce needs for hardware and spare inventory, and offer overall reduction in storage management and business costs. SATA drives carry a 1 year warranty. Pre-Failure Warranty Drives installed in a Modular Smart Array 20 and monitored under Insight Manager are supported by a Pre-Failure (replacement) Warranty (1 year for SATA drives). PreFailure Warranty allows for the replacement of designated drives in Modular Smart Array 20 before they actually fail when using Insight Manager on ProLiant servers. NOTE: Some operating systems may not support all of these features. Integrated Configuration and Management Tools The Modular Smart Array 20 utilizes the standard, integrated set of Smart Array management and utility software. These tools consistently lower the cost of ownership by reducing training and technical expertise necessary to install and maintain HP server storage.

Enclosure Features

The HP StorageWorks Modular Smart Array 20 (MSA20) is an Ultra320 host connect disk drive enclosure that uses Serial ATA (SATA) drives. The MSA20 delivers a low-cost, high-capacity solution that is suitable for minimum I/O workload situations such as storing reference data, archiving files, and performing disk-to-disk backups. You can connect the MSA20 to the external port of any sixth-generation Smart Array controller or to an MSA1500 controller shelf (MSA1500 cs). These external controllers enable you to configure the SATA drives in the MSA20 with RAID levels of 0, 1+0, 5, or ADG. The MSA20 also has an internal controller module with a battery-backed write cache. The cache allows data to be transferred rapidly to the SATA drives, and the batterybacked feature protects data held in the cache for up to four days if power to the enclosure is interrupted. The enclosure components incorporate some important safety and redundancy features. For example, if one power supply unit fails, the remaining functional unit can temporarily provide enough power for a fully equipped enclosure. Similarly, if one fan fails, the remaining fan runs at a faster speed, and can temporarily provide enough cooling for a fully equipped enclosure. In either case, replace the failed component as soon as possible to maximize the life expectancy of the remaining power supply or fan. For more information about features of the MSA20 enclosure, refer to the HP website, http://www.hp.com.

Installing the Enclosure in a Rack
Installing the enclosure in a rack involves four steps: Preparing the rack Removing the enclosure components to make the enclosure more manageable Mounting the enclosure in the rack Completing the installation process (reinstalling the components and connecting the power)

Preparing the Rack

The racks that HP supports for use with the MSA20 enclosure are the HP System E racks and the HP 10000 Series racks. Other racks might also be suitable, but have not been tested with the MSA20. For information about setting up a rack, including appropriate warnings and cautions, refer to the relevant rack user guide. Before mounting the enclosure in a rack, confirm that the rack location meets the environmental requirements for the enclosure as described in Appendix C.
Removing the Enclosure Components
IMPORTANT: The following abbreviated instructions are appropriate for removing the components from an enclosure that is not being used. To remove individual components from a working enclosure, refer to the complete instructions in Chapter 5.
Controller moduleSqueeze the finger hook and the release lever together while pulling the module out of the enclosure. Disk drivePress the release button, and then pull the release lever to remove the drive from the enclosure. Drive blankSqueeze the release latch while pulling the drive blank out of the enclosure. Fan assemblyLift the release lever upward while pulling it to remove the fan assembly from the enclosure. Power supply unitSqueeze the handle and the release lever together while pulling the unit out of the enclosure.
Mounting the Enclosure in the Rack
WARNING: Use at least two people to move or install the enclosure. For greater safety and easier installation, reduce the enclosure weight by removing the disk drives, power supply units, controller 9 kg (20 lb) empty module, and fan assemblies. 24 kg (53 lb) full

Each enclosure requires a vertical rack space of 2U (equivalent to 89 mm, or 3.5 inches). 1. Use the rack mounting template as a guide to indicate where on the rack the rails for the enclosure are to be mounted. a. At the front of the rack, with the front of the template facing you, align the lower edge of the template with the bottom of the rack (or the top of the previous rack component). Be sure that the lower edge of the template is level.
b. Push the template tabs into the holes in the rack uprights to hold the template in place.
c. Use a permanent marker pen to indicate the holes in the rack uprights into which the scissor-like locking latches are to be inserted, as specified by the template. d. Repeat these steps to mark the back of the rack, using the information on the back of the template as a guide to the required location of the locking latches in this case. 2. If the holes in the rack uprights are round instead of square, remove the standard pins from the rails and replace them with the round-hole pins provided in the rack mounting hardware kit.
WARNING: The pins in the rails are load-bearing. Do not remove the pins except to replace them with the pins for round-hole racks.
3. Identify the left (L) and right (R) rack rails by markings stamped into the rails.
4. Slide the front end of the right rack rail toward the inside front of the rack until the locking latch engages with the marked hole in the front rack upright.
5. Extend the back end of the rail toward the inside rear of the rack until the locking latch engages with the marked hole in the rear rack upright.
6. Loosen the locknut on the shipping bracket (1), and move the bracket to the rearmost position on the rail (2).
7. Repeat steps 4 through 6 for the left rack rail. 8. Align the enclosure with the rails, and slide it into the rack.
9. Remove the mounting bracket covers (1), and tighten the thumbscrews to secure the enclosure to the rack (2).
10. Replace the mounting bracket covers. 11. If you intend to move the rack while the enclosure is installed, adjust the shipping brackets on each rail to secure the enclosure to the rack. a. Loosen the shipping bracket locknut (1).
b. Slide the bracket forward until it engages with the enclosure chassis (2).
c. Tighten the locknut. d. Repeat this procedure for the other rail.
Completing the Installation
1. Reinstall the components in the enclosure. For details, refer to Chapter 5. 2. Connect the VHDCI connector on the controller module to the output of an MSA1500 cs or to the external connector of a sixth-generation Smart Array controller in a server. 3. Connect the AC input socket of each power supply unit to separate AC power sources. 4. Press the enclosure power button on the rear of the unit. 5. Confirm that the enclosure components are all functioning normally by observing the condition of their status LEDs, which should all be green. If the amber LED on any component is illuminated, the component needs attention for one of these reasons: It has suffered a critical fault. It is not seated properly in the enclosure.

In the case of a drive, it is predicted to fail in the near future (assuming that it is seated properly in the enclosure). In the case of a power supply, it is not plugged in.
Configuring the Enclosure Drives
The following tools are available for configuring the drives in an MSA20 enclosure: The HP Array Configuration Utility (ACU)A versatile, browser-based utility that provides you with maximum control over the configuration parameters The HP Option ROM Configuration for Arrays utility (ORCA)A simple ROMbased utility that runs on all operating systems The MSA1500 cs Command Line Interface (CLI)A tool for configuring and managing an MSA1500 cs and its attached storage
NOTE: Old versions of ACU and ORCA do not support the MSA20. Before using one of these utilities, upgrade the firmware and drivers on the external sixth-generation Smart Array controller. The latest version of ACU is downloadable from the HP website, http://www.hp.com.
For further information about using ACU, or for conceptual information about arrays, logical drives, and fault-tolerance methods, refer to the HP Array Configuration Utility User Guide. This document is available on the Documentation CD provided in the MSA20 kit. For further information about using ORCA, and for a detailed comparison of the features and capabilities of ORCA and ACU, refer to the user guide for the sixthgeneration controller to which the MSA20 is connected. This document is available on the Documentation CD that was provided in the controller kit. Alternatively, you can download a copy of the document from the appropriate controller-specific page on the HP website, http://www.hp.com. For further information about using the CLI, refer to the MSA1500 cs documentation at http://www.hp.com/go/msa1500cs.
Replacing Enclosure Components
All components are hot-pluggable. However, removing a component causes a significant change in the airflow within the enclosure, and the enclosure could overheat if a replacement component is not installed within a relatively short time. Before removing a component from the enclosure, be sure that a replacement component is immediately available. If removing a drive, replace it with another drive or a drive blank to maintain the correct airflow in the enclosure.
CAUTION: Be careful when replacing a drive. The drives in the enclosure are fragile.

Replacement Procedures

The following general steps apply to all components. Detailed procedures for removing individual components are given in the appropriate section of this chapter.
CAUTION: Before replacing a component, follow the precautions described in Appendix B to minimize the possibility of damage from electrostatic discharge.

CAUTION: To prevent damage to the cable connector, do not use excessive force when tightening the thumbscrews on the connector.
7. Confirm that the status LED on the replacement module is illuminated green.

Regulatory Compliance Notices
Federal Communications Commission Notice
Part 15 of the Federal Communications Commission (FCC) Rules and Regulations has established Radio Frequency (RF) emission limits to provide an interference-free radio frequency spectrum. Many electronic devices, including computers, generate RF energy incidental to their intended function and are, therefore, covered by these rules. These rules place computers and related peripheral devices into two classes, A and B, depending upon their intended installation. Class A devices are those that may reasonably be expected to be installed in a business or commercial environment. Class B devices are those that may reasonably be expected to be installed in a residential environment (for example, personal computers). The FCC requires devices in both classes to bear a label indicating the interference potential of the device as well as additional operating instructions for the user. The FCC rating label on the device shows the classification (A or B) of the equipment. Class B devices have an FCC logo or FCC ID on the label. Class A devices do not have an FCC logo or FCC ID on the label. After the class of the device is determined, refer to the corresponding statement in the following sections.

Electrostatic Discharge

Preventing Electrostatic Damage
A discharge of static electricity from a finger or other conductor may damage system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the device. To prevent electrostatic damage when setting up the system or handling parts: Avoid hand contact by transporting and storing products in static-safe containers. Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations. Place parts on a grounded surface before removing them from their containers. Avoid touching pins, leads, or circuitry. Always be properly grounded when touching a static-sensitive component or assembly.
Grounding Methods to Prevent Electrostatic Damage
There are several methods for grounding. Use one or more of the following methods when handling or installing electrostatic-sensitive parts: Use a wrist strap connected by a ground cord to a grounded workstation or computer chassis. Wrist straps are flexible straps with a minimum of 1 megohm 10 percent resistance in the ground cords. To provide proper ground, wear the strap snug against the skin. Use heel straps, toe straps, or boot straps at standing workstations. Wear the straps on both feet when standing on conductive floors or dissipating floor mats. Use conductive field service tools. Use a portable field service kit with a folding static-dissipating work mat.
If you do not have any of the suggested equipment for proper grounding, have an authorized reseller install the part. For more information on static electricity, or assistance with product installation, contact your authorized reseller.
