HeritageRAID-2S provides the latest disk drive technology in a simple and affordable package. By delivering high capacity, reliability, data availability, and bandwidth in both SAS or SATA configurations, HeritageRAID-2S meets the exploding data storage needs of today's IT departments. For applications such as disk-based backup, online archiving, disaster recovery, records management, medical imaging, video editing, email archiving, etc., reliable data storage has never been more affordable.

HeritageRAID-2S systems feature 4 Gb Fibre Channel or SAS host interfaces and attach directly to servers, networks, NAS engines or SANs where performance, reliability, scalability, and low cost is critical.

Performance
Equipped with a 64-bit RISC processor, up to 2 GB cache per controller and a fifth-generation 800 MHz data bus architecture, the HeritageRAID-2S is designed for performance critical applications and environments. A HeritageRAID-2S dual controller system delivers sustained reads of up to 750 MB/s and sustained writes of up to 500 MB/s in a 16 SAS drive RAID-5 configuration.

Reliability and Data Availability
HeritageRAID-2S provides high data availability with support for RAID levels 0, 1, (0+1), 3, 5, 6, 10, 30, 50, & 60. RAID 6 improves fault tolerance by implementing two parity drives. Other features such as dual active-active or active-passive controllers, controller failback, cache battery backup option, hot swappable drives, global & dedicated hot spares, automatic drive failure detection, automatic background rebuild, and redundant load sharing power supplies and cooling fans ensure that your data is available in the event of a component failure. All components are hot-pluggable.

Smart Technologies
The Innovative firmware design of the HeritageRAID-2S features intelligent drive technology that enhances I/O processing, drive handling, and system management.

IOSmart
IOSmart allows for the flexible configuration of logical drives, logical volumes and logical partitions and ensures instant RAID availability via background logical drive initialization. The firmware’s embedded intelligent algorithms, such as Adaptive Write Policy and Guaranteed Latency I/O, improve the performance of sequential write applications and ensure the fast and continuous flow of data.

DrvSmart
The DrvSmart utility provides an easy way to store data while keeping it safe. One of the main DrvSmart functions, Media Scan, retrieves data from degraded or damaged hard drives and handles low quality drives in both the degraded mode and during the rebuild process. Other DrvSmart features include disk cloning, drive roaming, SMART, transparent resetting of non-responsive hard drives, and RAID parity update tracking and recovery.

SysSmart
In addition to RAID protection for the disk drives, HeritageRAID-2S features Auto Data Protection Mechanisms. These special SysSmart firmware functions ensure data safety by automatically switching to write-through data caching when abnormal subsystem conditions are detected such as a PSU/cooling module failure, low BBU or UPS battery charge, etc. By using the firmware to monitor and control the enclosure's dual-speed fans, the fan rotation speed is raised to a higher level when critical conditions are detected, e.g., a PSU or fan failure. Fan speed returns to the lower setting when normal operating status is restored. The system can be monitored by variety of ways. I2C internal serial bus, SAF-TE, and SES are seamlessly integrated into the comprehensive Java-based GUI RAIDWatch Manager. Component status, voltage and temperature readings, and system events are instantly revealed through the manager's graphical interface.

Multi-Pathing
HeritageRAID-2S features EonPath multi-pathing technology, which provides a dynamic fault-tolerant technique that helps avoid downtime or data loss that can result from a connection failure in a single-path configuration. EonPath makes it possible to have more than one connection between the host and storage devices so that in case of failure the host can access the storage device via another path, thereby maintaining continuous operation and data availability. EonPath multipathing technology is comprised of two major functions—failover protection and load balancing—to provide high availability and improved performance.

Failover
EonPath supports failover redundancy between the host and the Heritage array by enabling the host operating system to transparently route I/Os over alternate data paths, so that disk access will not be interrupted by hardware failures.

Load Balancing
Load balancing increases I/O performance by redistributing read/write requests in order to maximize throughput between the host and storage devices. With EonPath, the operating system is aware of multiple data paths so it can reroute traffic to or from the storage devices to paths with available bandwidth, thereby increasing throughput, avoiding bottlenecks, and distributing the load equally.

Supported Platforms
Windows 2003 Server x86 & x64; Microsoft MPIO certified
Linux Red Hat AS v.3, EL v.4, Fedora v.5
Solaris SPARC 9/10 platform

Manageability
Management and monitoring of HeritageRAID-2S systems can be performed via an RS-232 terminal session or the network-based/in-band RAIDWatch management GUI.

RAIDWatch Manager
Accessible via TCP/IP or in-band, RAIDWatch is an easy-to-use, Java-based GUI RAID management software application. RAIDWatch provides a complete management interface to the RAID system and a constant real-time report of the current RAID status, errors, events, and capacity.

RAIDWatch enables administrators to quickly locate and rectify problematic hardware without downtime or data loss. Many RAID controller functions, such as RAID setup, RAID expansion, password management and firmware upgrades can be handled through the software console. The info window provides information on all installed hard drives and the key elements of the RAID controller. RAIDWatch also enables administrators to monitor current cache data status and system environmental conditions such as temperature and power.

Administrators can be notified virtually anywhere of events occurred by the powerful event notification utility, NPC (Notification Processing Center). Notification takes place via e-mail, LAN broadcast, SNMP, fax, and/or pager.

SANWatch
SANWatch provides instantaneous point-in-time "snapshot" copies of data that look and behave like complete backups without consuming equivalent disk space. SANWatch protects stored data from accidental or malicious loss, quickly performs data recovery, and easily retrieves lost data with minimum interference to system performance and I/O access. Snapshot images are ideal for various applications including backup, application testing or development, information analysis, and data mining.  Available as an option on H2S16100/200F24 models.

Configuration & Scalability
HeritageRAID-2S features 12 or 16 hot swappable Serial ATA II or SAS drives for capacity up to 16 TB in a single enclosure. The 16 bay FC host and the 12 bay SAS host models feature SAS expansion port(s) for JBOD expansion to 80 drives or 80 TB.
