  No single point of failure with redundant, hot-swappable components and a passive midplane. RAID controllers mask the drives’ SATA characteristics, presenting them to the host as high performance FC devices.
Key Differentiators
  Combined performance and connectivity benefits of Fibre Channel with the cost advantages of SATA drives. Passive, 3Gbit-ready, midplane.
Customer Needs
  Cost-effective, performance, and flexibility for the midrange storage market
System Environment
  Spheras RAIDWatch management GUI supported under Windows, Linux. OS Independent via serial port management
  Up to a maximum of 12 drives (4.8 TB) capacity per 2U enclosure with a total maximum of 96 drives (34.8 TB) capacity per subsystem
Network or Host Interface
  • One or two Fibre Channel controllers; each controller supports dual optical or copper (SFP) connections, 200 MB/s each (400 MB/s total)
  • Serial (RS232) port, Ethernet port, copper or optical (SFP) expansion port
Data Transfer Rate
Dual controllers: Up to 385 MB/s (sustained reads), 48,000 I/Os (cached reads)
Package Contents
  • Storage enclosure with either one or two controllers
  • Quick Install Guide
  • CD containing management software and user documentation
  • (Disk drives sold separately)
3-year warranty on subsystems (3 year warranty on SATA disk drives)
