Specifications

RAID

1. Multiple arrays configurable with dedicated or global hot spares
2. RAID levels supported: RAID 0, 1 (0+1), 3, 5, 10, 30, 50, and NRAID
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
   1. In degraded mode: Skipping irreparable blocks to continue rebuild
   2. In normal operation: Data block verification and repair

System Components

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

1. One (1) EonStor 3U RAID subsystem enclosure
2. One (1) RAID controller module [EonStor A16F-S1211] or
   Two (2) RAID controller modules [EonStor A16F-R12112]
3. One (1) 256MB(or above) SDRAM DIMM module (pre-installed on the controller module) per controller module
4. Two (2), hot-swappable, redundant, 460W power supply units
5. Two (2), hot-swappable, redundant, dual-fan, cooling modules
6. Sixteen (16), hot-swappable, drive trays each with a preinstalled MUX kit
7. One (1) LCD panel (pre-installed on the left side front handle)
8. Two (2) front handles

Management

1. Firmware-embedded Java-based GUI RAID manager
2. Centralized management of multiple arrays over in-band or Ethernet
3. Real-time event notification over Email, LAN broadcast, or SNMP traps
4. Host-side SES emulation with pass-through to back-end SES emulation
5. SNMP 2.0 MIBs with get and set commands
6. Firmware-embedded utility via LCD keypad or RS-232C (audio jack) serial port
7. Module status LED indicators
   1. Two (2) per drive tray
   2. Two (2) per cooling module
   3. One (1) per power supply unit
   4. Eleven (11) per RAID controller module
8. Onboard alarm is triggered when one of the following modules fails:
   1. RAID controller module
   2. Cooling modules
   3. Power supply unit
   4. Hard drive
   5. Serial port communication with PC hyper-terminal

Drive Interface

1. Up to 1024 LUNs if sufficiently large memory is used with the proper settings
2. Supports 3.5", 1" high hard disk drives
3. Sixteen (16) hot-swappable drive trays
4. Single dual loop across 16 drives within enclosure
5. Automatic bad sector reassignment
6. Drive hot-swappable via SCA-II connectors
7. Dedicated bandwidth to each connected drive

Host Interface

1. Auto-negotiate FC-AL, point-to-point, and switched fabric
2. Concurrent I/O commands
3. Tagged Command queuing up to 256
4. Variable stripe size per logical drive
5. Optimization setting for random or sequential I/Os

Maintenance & Availability

1. Firmware rolling upgrade on redundant RAID controllers
2. Synchronized cache over dedicated Fibre channel
3. Comes standard with a Li-ION battery module
4. Immediate array availability
5. Drive roaming, array configuration on drives
6. Controller voltage and temperature self-diagnostics
7. Auto switch cache policy and Auto shutdown
8. When a RAID controller detects conditions exceeding preset thresholds, the following actions will be exerted to protect the hardware:
   1. The cached data will automatically be flushed and the array’s caching mode will be switched from write-back to write-through
   2. Commence an auto shutdown

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

Physical/Electrical

Interfaces

1. Five (5) SFP sockets per controller module that use short-wavelength adapters
2. One (1) RJ-45 Ethernet port per controller module
3. Two (2) RS-232C (Audio Jack) serial ports (38400, n, 8, 1) per controller module (one is for terminal emulation, the other is for UPS support)

Power Supply Unit (PSU) modules

Two (2) redundant, hot-swappable, 460W, PSU modules with PFC.

Cooling Modules

Two (2), redundant, hot-swappable, dual-fan, cooling modules

* Note there are a total of four fans (two in each cooling module)
