VIDOS-NVR RAID-5 data storage unit


  • SATA single controller RAID subsystem with 4Gbps Fibre Channel host I/F providing full-featured RAID functionality
  • Auto switch cache policy and auto shutdown
  • Support for up to 1GB cache memory
  • Intelligent drive handling

Specifications

RAID

Multiple arrays configurable with dedicated or global hot spares

RAID levels supported: RAID 0, 1 (0+1), 3, 5, 6, 10, 30, 50, 60, NRAID and JBOD

Online expansion by

  1. Adding new drives
  2. Copying and replacing drives with drives of larger capacity

Automatic background rebuild

Configurable stripe size and write policy per array

Intelligent drive handling:

  • In degraded mode: skips irreparable blocks to continue rebuild
  • In normal operation: data-block verification and repair

Host Interface

2 x 4Gbps Fibre Channel

Concurrent I/O commands

Tagged command queuing up to 256

Variable stripe size per logical drive

Optimization setting for random or sequential I/Os

Drive Interface (depending on model)

Eight (8) / Twelve (12) / Sixteen (16) / Twenty Four (24) 3Gbps SATA, hot-swappable drive trays that accommodate 1-inch pitch, 3.5-inch SATA disk drives

8/12/16/24 hot-swappable drive trays

Automatic bad-sector reassignment

Dedicated bandwidth to each connected drive

Management

Front LCD control panel for setup and configuration

10/100 BaseT Ethernet for out-of-band management

RS-232C for local access to firmware-embedded utility

Firmware-embedded Java-based RAIDWatch™ GUI manager

  • VT-100 terminal emulation via RS-232C
  • Telnet access via onboard Ethernet port
  • Cross-platform, remote administration with SSL
  • Out-of-band access via Ethernet (GUI-onboard)
  • Centralized management to monitor and administer multiple RAID units on one screen

SNMP agent support:

  • SNMP trap event notification with plain-text event message (no MIB file required)
  • SNMP V2.0 MIB file support with get-and-set commands

Indicators

Onboard alarm is triggered when one of the following modules fails:

  • RAID controller module
  • Cooling module
  • Power supply unit
  • Hard drive

Notification Processing Center (NPC) for real-time event notification over email, LAN broadcast, or SNMP traps

Module status LED indicators:

  • Two (2) per drive tray
  • Two (2) per cooling module
  • One (1) per power supply unit
  • Three (3) per LCD panel
  • Six (6) per RAID controller module

Auto switch cache policy and Auto shutdown

When a RAID controller detects conditions exceeding preset thresholds, the following actions will be exerted to protect the hardware:

  • Cached data is automatically flushed and the array’s caching mode switches from write-back to write-through mode.
  • If conditions persist past the preset period of time, auto shutdown of the controller will commence.

All thresholds associated with this mechanism are user configurable and, once a subsystem manager restores the normal operating conditions, the caching mode changes from write-through back to write-back mode.

Intelligent Drive Handling

If two bad blocks occur on two member drives of an array, the integrity of the stored data is endangered. Media Scan, the innovative intelligent drive handling function, retrieves data from the damaged sectors. Media Scan handles low quality drives in both the degraded mode and during the rebuild process. For additional data security, other intelligent drive management features include the transparent resetting of hung hard drives, power-failure management, and bad-drive handling during LD expansion.

VIDOS the intelligent management software
 
Run your CCTV system the way you want to with VIDOS the intelligent all-in-one management system.

Ideal for set-up, administration and day-to-day management of networked CCTV systems

Mix and match digital and existing analogue components. From S to XXL - VIDOS is fully scalable to any number of cameras and any storage requirements

For recording and playback, VIDOS integrates seamlessly with our VIDOS-NVR networked video recorder and features simultaneous recording, searching and playback of multiple cameras
 

 
 
VIDOS-NVR Network Video Recorder
 
VIDOS-NVR adds networked video recording to VIDOS and VIDOS-Pro.

Each unit can record up to 64 channels of MPEG-2 and MPEG-4 video data; the system can be extended to support any number of cameras just by adding the appropriate number of VIDOS-NVR units

VIDOS-NVR uses standard PC servers with attached RAID disk arrays, featuring a price/performance ratio dramatically superior to DVRs

It includes the patented ANR technology which ensures recording even if the network is down
