Highlights
- The best end-to-end I/O performance in RAID5 configuration:
- Sequential Reads: 426 MB/sec
- Sequential Writes: 248 MB/sec
- Ultra High Density, 2U, 12-bay enclosure with full featured single controller architecture
- Two SCSI-320 host channels; transfer rates up to 320MB/sec
- Two SCSI-320 drive channels; each channel attaches to eight drives
- Redundant hot swappable components
- Storage capacity is easily increased by daisy chaining additional U12U-G4020 subsystems
- Dual speed cooling fans to reduce system noise
- Optional, hot swappable battery backup unit (BBU)
- Effortless management through the LCD keypad, RS232-C terminal, or Java based management GUI over the internet
Reliability
The AV-U12U-G4020 leverages the reliability of SCSI-320 technology to provide rock solid data integrity. The subsystem offers full featured data protection and support for RAID levels 0, 1(0+1), 3, 5, 10, 30, 50, NRAID and JBOD. Its flexible design allows the AV-U12U-G4020 to be connected to single or dual hosts. Data saftey can be further guaranteed by installing an optional battery backup unit (BBU) and uniterruptable power supply (UPS) which can extend the operating time for the entire subsystem during a power failure.
Availability
The AV-U12U-G4020 subsystem comes with fully featured RAID capabilities, and special care has also been taken to ensure that all possible causes of data loss have been eliminated. All critical components including the disk drives, power supply units and cooling modules, are hot swappable within the cableless, modular chassis.
This highly flexible design features two dual stacked VHDCI SCSI-320 connectors for host connections and storage expansion by daisy chaining additional U12U-G4020 subsystems.
The AV-U12U-G4020 is your best choice to satisfy your organisation's need for 24/7 data availability and increasing storage demands.
Serviceability
This high density subsystem provides space effieciency along with simple, cost effective expandability. You can easily add capacity in single drive increments or daisy chain another AV-U12U-G4020 to expand storage whenever you need it.
The modular, field replaceable units (FRUs) can be conveniently accessed through the front and rear panels to ensure the ease of the subsystem maintenance.
Manageability
The AV-U12U-G4020 is extremely easy to deploy, configure, manage, and monitor via its variety of management interfaces. The subsystem comes standard with an ethernet port for local or remote management using simple telnet protocol or the feature rich RAID management GUI.
The Java based RAID management GUI provides graphical presentations of array components, monitoring windows, and configuration windows. Best of all, system administrators can be constantly aware and automatically notified of array status using any or all of the following 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-U12U-G4020 uses the industry leading Seagate 10K.7 SCSI-320 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
