Features & Benefits

High Reliability
Featuring redundant 80PLUS Platinum power supplies, redundant cooling fans, and 12Gb/s dual-domain SAS expander I/O modules Zstor AJ496 guarantees reliability and ensures continuous operation in mission critical applications. With its truly isolated design of fan module, the rotational vibration (RV) energy can be minimized and controlled not to interfere with hard disk drive operation.

High Flexibility
The four SFF-8644 ports of its external SAS I/O modules can be configured for host connection or cascading. With this daisy chain feature, the Zstor AJ496 is flexible on storage capacity expansion and deployment to address the specific requirements of different applications.

High Serviceability
Its tool-less HDD trays can save HDD installation time up to 80%, and its tool-less top covers, a long travel slide rail, 37.4“ (950mm travel) weighted 150kg in maximum, make installation and maintenance an easier job. Moreover, a rear-mounted redundant BMC module allows remotely monitoring system status, power on/off, and on-line expander firmware upgrade.


More Value to the Data Center

Data centers are facing growing pressures. Data volume is expanding, operating costs are rising, yet budgets remain flat. Lowering the total cost of ownership (TCO) has become the focus of data center architects and the combination of Zstor AJ496 JBOD with Ultrastar He12 HDD provides the best value proposition and greatest storage efficiency available.

AJ496 realizes more than 1 PB in 4U
Using HGST latest 12TB datacenter graded SAS 12G hard disk drives gather into a raw capacity of 1.152 PetaByte available as centralized storage within Software Defined Storage environments

     HGST He12 12TB                        12TB capacity in 3.5“ format
• HelioSeal Technology
• 2.5M hours MTBF
• 54% more power efficient
• 25% higher reliability
