Third Party Enclosure  
  MTC 316 W & MTC 424 Enclosures With Areca Series 12Gb/s Products  




ARC-8028 12Gb/s SAS Expander Module
(Three SFF-8644 ports: one host and others for expansion to additional JBOD enclosures)


The ARC-8028 supports DataBolt™ Bandwidth Optimizer to buffer 6Gb/s data and then transfer it out to the host at 12Gb/s speeds in order to match the bandwidth between faster hosts and slower SAS or SATA devices. It also supports failover function for improving system reliability for today’s data center and storage subsystems.

Flexible 36-port SAS expander module
  DataBolt™ Bandwidth Optimizer for balance faster
    hosts and slow SAS or SATA devices

Integrated ARM enclosure processor for SAS SMP
    functions and SES support
  Supports narrow and wide port configurations

Supports SAS and SATA drives simultaneously and
    compatible with leading SAS & SATA drives, SAS
    HBAs, and SAS RAID controllers
  UART interface for system monitoring and debugging

SFF-8485 compliant Serial GPIO (SGPIO) interface
    on internal SFF-8643 connector
  Support autonomous chassis management

Dual expander module option support
  LCD Control Panel for easy interactive with module

ARC-8028MB-Mounting Bracket


An ATX I/O Shield is a small metal plate located at the back of each rackmount chassis that provide openings for different I/O ports of a motherboard.

ARC-8028MB-Mounting Bracket for user to leverage the ATX I/O Shield position as ARC-8028 box I/O port. You can use ARC-8028MB to fit ARC-8028 box I/O port in the standard ATX I/O-Slot found in a Rackmount Chassis.
