ESFWBU2ATA525QAR5 is most cost-effective ATA hard disk drive RAID subsystem with completely integrated high performance and data protection capabilities. ESFWBU2ATA525QAR5 takes full advantage of high-speed Serial ATA/1394/USB serial bus and ATA bus allowing for multi-user and multitasking performance. ESFWBU2ATA525QAR5 delivers the performance required for servers and I/O demanding applications such as Video-On-Demand, database servers, workstations, high-end desktops, and image systems. ESFWBU2ATA525QAR5 allows one HDD failure without impact on the existing data and failed drive rebuild is transparent to the host. Environmental information is accessible either via the control panel or RS-232 serial port.

  • LCD Control Panel: To simplify the RAID setup and management of the associated disk drives.
  • Allows manual RAID configuration and status monitoring
  • Uses hardware monitor to monitor system voltage, temperature and fan activity
  • Displays warning message on LCD screen when respective disk encounters problems
