RAID

System Components

1. Multiple arrays configurable with dedicated or global hot spares
2. RAID levels supported: RAID 0, 1 (0+1), 3, 5, 10, 30, 50, NRAID, and JBOD
3. Online expansion by
   1. Adding new drives
   2. Copying and replacing drives with drives of larger capacity
4. Automatic background rebuild
5. Configurable stripe size and write policy per array
6. Intelligent Drive Handling
7. In degraded mode: Skips irreparable blocks to continue rebuild
   1. In normal operation: Data block verification and repair
   2. Task Scheduler: Hands-free Media Scan maintenance

Redundant, hot-swappable components, designed for no single point of failure

1. 3U RAID enclosure
2. Single RAID controller
3. Sixteen drive trays
4. Dual redundant power supplies
5. Two hot-swappable cooling fan modules

Management

1. Java-based GUI RAID manager
2. Centralized management of multiple arrays over in-band SCSI or Ethernet
3. Event notification: email, LAN broadcast, fax, SMS, MSN, ICQ, or SNMP traps
4. Auto on-lining of cascaded enclosures
5. Enclosure status report through an I²C link connection
6. SNMP 2.0 MIBs with get and set commands
7. Firmware-embedded utility via LCD keypad or RS-232C terminal

Drive Interface

1. 3.5", 1" high SCSI-320 disk drives
2. 16 hot-swappable drive trays
3. Automatic bad sector reassignment
4. Drives hot-swappable via SCA-II connectors
5. Dual channels across sixteen drives within each enclosure

Host Interface

1. G4010-4: 2 VHDCI 0.8mm SCSI
2. G4010-6: 4 VHDCI 0.8mm SCSI (two configurable as host or drive)
3. Concurrent I/O commands
4. Tagged Command queuing up to 256
5. Variable stripe size per logical drive
6. Optimization setting for random or sequential I/Os

Maintenance & Availability

1. Optional Li-ION battery support
2. Immediate array availability
3. Drive roaming, array configuration on drives
4. Auto Switch Cache Policy and Auto Shutdown

When a RAID controller detects conditions exceeding preset thresholds, the subsystem automatically flushes cached data and switches the array’s caching mode from write-back to write-through.

All environmental thresholds associated with this mechanism are user-configurable; the caching mode changes back to write-back once normal conditions are restored.

Physical/Electrical

Interfaces

1. Two (G4010-4) or Four (G4010-6) VHDCI 0.8mm connectors
2. One DB-9 RS-232C serial port (38400, n, 8, 1)
3. One RJ-45 Ethernet port

Power Supply

1. Two redundant, hot-swappable power supplies with PFC
2. Input: 90 to 260VAC, 47 to 63Hz
3. Output: +5V, 25A max.; +12V, 32A max.; +3.3V, 20A max.; 460 Watt capacity

Cooling Module

Four cooling fans in two separate modules
