Description

Introduction

Combining the high performance, reliability, and extensive connectivity of 4G Fibre Channel interfaces with the cost-effective SATA drive technology, these entry-level, SAN-ready subsystems provide clustering capabilities for DAS, Fibre Channel SAN, and are well suited for imaging and archiving or secondary storage.

Features

• FC-4G to SATA-II (3Gbps) single controller RAID subsystem
  
• RAID5 configuration end-to-end I/O performance: Sequential read:545 MB/sec, Sequential write:345 MB/sec
  
• Dual-speed fans to reduce noise
  
• 2U chassis providing up to 8TB or 12TB of storge capacity
  
• SATA NCQ support

Specifications

RAID

• RAID levels supported: RAID 0, 1 (0+1), 3, 5, 10, 30, 50, and NRAID
  
• Online expansion by:
  
  
  
  • Adding new drives
    
  • Copying and replacing drives with drives of larger capacity
  
  
• Automatic background rebuildsConfigurable stripe size and write policy per arrayIntelligent drive handling: In degraded mode: skips irreparable blocks to continue rebuild, In normal operation: data-block verification and repair
