24 bays 2U High Density Rackmount 32Gb Fibre to 6Gb SAS/6Gb SATA RAID Subsystem

The New AH-825c Series is the first High Density RAID subsystem PetaStor owns. The 2U/24Bay, High Density RAID storages combine performance, scalability, and availability to meet growing data needs.

The AH-825cFUS / AH-825cFUD High Density RAID subsystem contain a dual core processor and DDR3 memory. AH-8 series deliver excellent performance based on Quad 32Gb Fibre ports for host connectivity on each controller in a 2U24-bay chassis supporting 6Gb/s SAS & SATA /SSD 2.5″ HDD.

With JBOD enclosures (SAS Expander) supporting up to 256 SAS/SATA devices connected, AH-825 Series is capable of providing over 400TB gigantic storage capacity without sacrificing performance.

The AH-825c Series data storage solution is built on high performance RAID-on-Chip( ROC ) 1.2GHz Dual Core storage processor with PCI-Express 3.0 bus architecture, and up to 8Gb DDR3-1866 memory.

The AH-825c Series offer an ideal storage solution, for those who need high performance, high capacity and a fault tolerance storage solution within a small footprint.
