HeritageRAID-SA brings Serial ATA RAID to the enterprise. By delivering high capacity, scalability, reliability, data availability, and bandwidth at the low cost of SATA drive technology, HeritageRAID-SA 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-SA systems feature Fibre Channel, SAS, SCSI or iSCSI interfaces and attach directly to servers, networks, NAS engines or SANs where performance, reliability, and low cost is critical.

High Performance
Equipped with a 64-bit RISC processor and 266 or 400 MHz data bus architecture, the HeritageRAID-SA is designed for performance-critical applications and environments.  A HeritageRAID-SA Fibre system with a single controller delivers sustained RAID5 Read/Write at 658/460 MB/sec and sustained RAID6 Read/Write at 651/411 MB/sec.

Reliability and Data Availability
HeritageRAID-SA provides high data availability with support for RAID levels 0, 1, (0+1), 3, 5, 10, 30 & 50. RAID level 6, available on certain models, improves fault tolerance by implementing two parity drives. Other features such as controller failback, 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 for simple maintenance.  HeritageRAID-SA arrays are integrated with RAID Edition disk drives, providing high reliability in 24 x 7 environments.

Smart Technologies

The Innovative firmware design of the HeritageRAID-SA 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-SA 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.

Software Features
Management and monitoring of HeritageRAID-2S systems can be performed via an RS-232 terminal session or the network-based or in-band management GUIs.

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 Manager
SANWatch is a Java-based management GUI that provides all functions necessary to discover, configure, administer, and monitor HeritageRAID-2S arrays.  With all the functions of RAIDWatch, SANWatch also provides management interfaces for the following modules so that all data protection and high availability features can be accessed through one interface.

1. Centralized Management Console
2. Configuration Manager
3. Storage Manager
4. Disk Performance Monitor
5. Notification Manager
6. EonPath Manager
7. Virtualization Manager

EonPath
EonPath provides multi-path I/O functionality by recognizing and managing the redundant paths to an individual RAID volume. Greater reliability is achieved through the path failover mechanism in the event of cabling component failure.  EonPath also comes with load-balancing algorithms which help accelerate the throughput across host-storage data links.  Supported functions include active-active/active-standby path redundancy, intelligent load-balancing, I/O traffic monitoring, and multiple paths to RAID volumes.

Configuration & Scalability
HeritageRAID-SA features 4, 8, 12, 16 or 24 hot swappable Serial ATA II drives for capacity up to 48 TB in a single enclosure.   A 24 Bay SAS host model supports four 16-bay JBOD expansion chassis for up to 64 drives in a single configuration.  With the additional cascade ports, RAID or expansion enclosures can be easily attached to include a total of an astonishing 528TB capacity (using 2TB SATA drives).
