Fibre to Fibre RAID Subsystem

Built around a next-generation, custom ASIC266 with XOR engine, the AV-Stor AV-F16F-R/S2021 subsystem is created for today's data intensive application demands.

This SAN-ready subsystem is designed to meet the demands of 24/7 operation and is the perfect choice for high-bandwidth applications such as high performance computing, financial transactions, medical imaging, and video streaming.

This new member of our line of 2Gbps Fibre Channel (FC to FC) products, the AV-STOR AV-f16F- R/S2021 RAID subsystem provides the high density of 16 drives in a 3U chassis. Using sophisticated RAID technologies, including a high-performance ASIC266 with XOR RAID engine and comprehensive firmware functionalities, the AV-F16F- R/S2021 delivers benefits derived from Avante Digital's years of experience in RAID storage.

The RAID functionality is unmatched in the industry in terms of its wide variety of aray configuration, maintenance, and monitoring capabilities. The Single or redundant controler, AV-F16F- R/S2021 subsystem provides IT professionals with versatile options to meet their needs.

  • The best AV-F16F-R2021's end-to-end I/O performance in RAID5 configuration:
    • Sequential Reads: 725 MB/sec
    • Sequential Writes: 487 MB/sec
  • Seagate Cheetah 10K.7 high performance Fibre Channel disk drives
  • Full-featured single or dual controller architecture
  • Six FC-2G channels routed to twelve Fibre Ports (Four ports may be assigned as drive or host ports for additional flexibility)
  • High redundancy level with separate host and drive I/O boards
  • Support up to 2GB Cache per controller
  • Support for up to 248 drives by cascading up to 14 expansion subsystems
  • Modular, passive backplane, high redundancy enclosure design
  • Dual speed cooling fans to reduce system noise and power consumption
  • Hot Swappable battery backup units (BBUs)
  • Easy management through the LCD keypad, RS-232 Terminal or Java based RAID manager over the internet

The AV-F16F-R/S2021 is a full-featured data protection subsystem supporting RAID levels 0, 1(0+1), 3, 5, 10, 30, 50, NRAID, and JBOD. The Flexible design alows the AV-F16F-R/S2021 to be configured for a wide range of applications.

The subsystem is equipped with one (1) BBU in AV-F16F- S2021 and two (2) BBUs in AV-F16F-R2021 that provide power to cache memory during a power failure. The subsystem further guarantees data safety by supporting the installation of an uninteruptible power supply (UPS) which can extend the operating time for the entire subsystem if a power outage ever happens.

Combined with firmware features such as DrvSmart and SysSmart, the AV-F16F- R/S2021 delivers reliable, consolidated storage for today's enterprise environments.


The completely cableless, backplane-based design elimates problems associated with cable connections to offer a higher level of serviceability and hot-swappability.

Major hardware configurations, such as enclosure ID setting, enable/disable hub, and FC channel speed, can be adjusted using easily accessible DIP switches on the enclosure configuration card located on the subsystem rear panel.

The modular nature of the subsystem and teh easy accessibility to all field replaceable (FRUs) through fron and rear panels ensure easy subsystem maintenance.


A variety of management interfaces are available. The array can be accessed through the LCD keypad panel, RS-232C terminal, telnet, or remotely through the Java RAID manager. The RAID manager provides "Install Once, Run Anywhere" convenience with a graphical user interface.

Users are constantly aware and automatically notified of array status using any or all of the following notification methods:-

  • email
  • fax
  • LAN broadcast
  • SNMP traps
  • MSN Messenger
  • ICQ
  • SMS messages

Smart Technologies

Derived from more than ten years experience in RAID storage design, the AV-STOR innovative firmware delivers Smart technologies that provide enhanced storage solutions for every customer environment, from small organisations to large enterprises. These technologies enhance I/O processing, drive handling, and system management.

  • IOSmart
    IOSmart alows for the flexible configuration of logical drives, logical volumes and logical partitions and ensures instant RAID availability via background logical drive initialization. Fibre loops' load balancing is provided within the subsystem. The firmware's embedded inteligent algorithms, such as Adaptive Write Policy and Guaranteed Latency I/O, improve sequential write performance 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 reseting of non-responsive hard drives, and RAID parity update tracking and recovery.
  • SysSmart
    SysSmart combines enclosure monitoring and firmware management capabilities in order to minimize the chance of down time caused by hardware failures. The Auto data protection mechanisms are developed to ensure data safety. Other SysSmart functions include the event-triggered and the various monitoring utilities and monitoring approaches combined with the RAID manager. Component status, voltage and temperature readings, and system events are instantly revealed through the manager's graphical interface.
Disk Drives

The AV-F16F-R/S2021 uses the industry leading Seagate 10K.7 Fibre Channel disk drives.

Features Benefits
Full Duty Cycle Reliability
The Cheetah 10K.7 is designed to have the highest reliability, even when in used in demanding applications around the clock, 365 days per year. 
Background Media Scan
Background Media Scan, a Seagate-exclusive feature, scans the media during drive idle time to preserve system bandwidth while enabling incipient errors to be corrected before data is lost.
Enhanced Error Correction Code
Decreased bit error rate better maintains performance throughout the life of the drive and results in a lower probability of lost data.
Fluid Dynamic Bearing Motor
No ball bearings means reduced acoustics and improved reliability.
Low Power and Cooling Requirements
Further reduces cost of ownership
Highest Reliablity Rating
Reliability has a significant influence on a disc drive's total cost of ownership. Cheetah 10K.7 has an 0.62 percent AFR, the best in the industry.

Major Markets and Uses

Avante Digital products are used in server-attached and networked data storage in major industries such as medical imaging, multimedia on demand (MOD), and digital media including video-on-demand, stream editing and more
