SharqStor FS 4240

Overview

The SharqStor FS 4240 is a 4U FC(2G) to SATA RAID array subsystem designed for connection to a host fibre channel HBA or SAN fabric. The FS 4240 is an ideal option for mid-range and high-end direct attached storage applications, high availability clustering, high performance computing clustering, scalable SAN installations and OS virtualization.

  • 4U Chassis
  • 24 SATA-II Drive Bays
  • Dual Redundant RAID Controllers
  • Four FC-2G ports

The SharqStor FS 4240 fabric attached storage subsystem comes with two (2) 2Gb per second (Gbps) Fibre Channels interfaced through eight (8) small form-factor pluggable (SFP) ports on two (2) independent I/O modules with embedded bypass. The subsystem's 4U-profile, rackmountable chassis houses dual-redundant RAID controllers featuring complete RAID protection and data integrity functionality. Designed for no-single-point-of-failure (NOSPOF), overall operation is protected by redundant, hot-swappable power supplies and cooling fan modules. All major components are hot-replaceable, including the Li-ION battery, host I/O modules, and RAID-protected disk drives.

The subsystem provides high-density array capacity with twenty-four (24) drive bays for SATA-II disk drives, facilitates large I/O transfer over its dual PCI-X bus architecture, and combines the capabilities and block-level performance of RAID storage with reliable Fibre Channel connectivity.
