Intelligent shared storage enclosure to simplify clustering with the latest, industry-standard ProLiant Servers from HP
Modular Smart Array 500 is specifically designed for an easily deployable 2-node cluster or direct attached storage to a single node. It is based on SCSI technology, making it a familiar and cost effective and easy to deploy solution. The redundant controllers, built on Smart Array technology, provide an increased level of data availability external to the server node, The Modular Smart Array 500 has been designed for fault resiliency with controllers, battery-backed write cache, power supplies, and cooling, providing the customer with a high degree of data availability.

Increase fault tolerance by adding dual I/O paths to the same logical volumes.
Smart Array Multipath software delivers dual path functionality and supports failover capabilities for redundant host bus adapters (HBAs) in a server with redundant cabling to a Modular Smart Array 500. This fault-tolerance tool enhances availability of clustering and direct attached storage (DAS) solutions with up to two servers managing up to 2 TB of stored data. When an HBA failure occurs, the software moves the logical drives from the path of the failed HBA to the path of the redundant HBA located in the same server.

- Increase availability by protecting against connectivity (HBA) failures and cable pull-outs.
- Ships with 4-Port module at no additional cost
- Static LUN Balancing
- Static Load (read-only) Balancing
The Modular Smart Array 500 solution has been designed to provide the highest level of redundancy with SCSI economics. It is equipped with an array of redundant features, including redundant controllers, the option for redundant path the same logical volumes, cooling fans, and power supplies that provide affordable high availability features. In addition, the Modular Smart Array 500 Controllercomes equipped with an LCD screen to show system health and status messaging, providing an enhanced customer experience. Battery Backed Write Cache is standard in the Modular Smart Array 500, it is removable and transportable and it may be upgraded to 512MB. In case of power failure, the batteries on the cache will protect the data in the cache for up to three days. Redundant batteries on the cache module provide an extra layer of data protection. Finally, the Recovery ROM will protect against errors when flashing the ROM by allowing the system to fall back to the previously installed firmware version.

Maximize your storage utilization by allowing up to 4 direct attached servers to share the Smart Array Cluster Storage
Deploying independent servers with its own internal storage may leave unused drive capacity in each server. By using the Smart Array Cluster Storage as the shared storage component up to four servers can share the Smart Array Cluster Storage and its drives. SSP is used to create logical volumes and each volume is assigned to a server. By being able to expand capacity online and also extend logical volumes online capacity can be added at any time. Migrating hard drives from the ProLiant serves to the Smart Array Cluster Storage is simple with DtS technology
- Share Smart Array Cluster Storage with up to 4 servers
- Greater external storage capacity utilization;
- Use SSP to assign logical volumes for each server
- Boot from external or internal hard drives
- Maintains simplicity of Smart Array
- Easily migrate to FC-SAN

The Smart Array Cluster Storage attaches to the embedded SA-5i, 5i Plus or SA-532(PCI) controller, no additional hardware investments are required for deployment. Given the cost of Fabric Switches, Hubs, and HBA's, and Fibre Channel cables the savings could be significant.

HP management tools offer superior management capabilities
HP management tools offer superior management capabilities HP management tools such as Insight Manager, ACU (Array Configuration Utility) and the diagnostics utility ADU offer superior management capabilities to simplify installation and management.
HP remote management products allow IT administrators to perform all of the "in-front-of-the-server" functions such as deployment, configuration, maintenance, system rebooting (servers), troubleshooting, disaster recovery, and application installation without physically visiting the server and storage. HP's Remote Insight Lights Out Edition (RiLOE II) and the new Integrated Lights Out (iLO) are powerful, hardware-based remote administration and control of ProLiant servers from a standard web-browser to conserve valuable IT staff resources that provide maximum security, availability, and control over business-critical ProLiant servers and storage without the need to physically visit the systems.
Smart Array Cluster Storage Controller Management Features
- Online RAID Level Migration: allows for online post-configuration change to RAID level without destroying data or volume information.
- Online Capacity Expansion: lets you add storage to an operational Smart Array Cluster Storage-reducing expensive server downtime.
- Online Volume Extension: allows for the capacity growth of existing logical volumes.
- Global Online Spare: reduces the risk of data loss by facilitating automatic rebuilds after a drive failure.
- Logical Drive Capacity Extension: allows the user to increase the size of existing logical drives online under Windows NT and offline for other operating systems.
- Online Stripe Size Migration: Allows to change stripe sizing of a logical volume
- User Selectable Read/Write Cache size, dynamically allocate cache sizes.
- User Selectable Expand and Rebuild Priority
- Auto Controller Firmware Cloning with redundant controllers.
Fault Tolerance
Several fault tolerant configurations, which keep data available and servers running while drives are being replaced, are supported including:
- Smart Array Multipath, adds a redundant I/O path to the same logical volume.
- Advanced Data Guarding (RAID ADG): Allocates the equivalent of 2 parity drives across multiple drives and allows simultaneous write operations.
- Distributed Data Guarding (RAID 5): Allocates parity data across multiple drives and allows simultaneous write operations.
- Drive Mirroring (RAID 1, (1+0 Striped Mirroring)): Allocates half of the drive array to data and the other half to mirrored data, providing two copies of every file.
Controller Cache Upgrade
- Cache on the Smart Array Cluster Controller may be upgraded to a maximum of 512MB (2 x 256MB)
- Array Accelerator: Onboard, battery-backed cache memory protects data in the event of a power failure. In the unlikely event of a controller failure, the battery-backed cache will save critical user data for up to three days.
Enhanced Firmware Auto-Cloning
Enhanced Firmware Auto-Cloning allows customer choice of controller firmware cloning when adding new controller with higher firmware version. When installing the redundant Smart Array Cluster Controller, the controller verifies the firmware version currently installed in the primary controller. If the firmware versions of the controllers do not match, then the customer may choose the following courses of action:
1. Upgrade to the highest firmware version
2. Downgrade to the lower firmware version, thus remaining with the current functioning version.
Fault Recovery
- Minimizes downtime, reconstructs data, and facilitates a quick recovery from drive failure
- On-Line Spares: If a failure occurs, recovery begins with an on-line spare and data is reconstructed automatically. One on-line spare can be assigned per array and used across multiple arrays. It is also possible to assign different on-line spares across different arrays.
