A34812-ITX

$1,080.00 each

   The A34812-ITX is a 48-lanes 12Gb/s SAS/SATA expander in a mini-ITX form factor. This complete subsystem incorporates everything system vendors need to add next-generation storage support for JBOD and RBOD systems that need to support SAS and SATA target disks. Each SAS lane can connect to a disk, a host bus adapter (HBA) or cascade to another expander device. When configured for cascaded connections, the A34812-ITX allows a single SAS RAID or HBA card to drive hundreds of target disks. With support for LSI DataBolt(tm), the A34812-ITX expander board helps to maximize bandwidth utilization between legacy 3Gbps and 6Gbps media, and 12Gbps SAS hosts.  For additional performance, lanes can be aggregated into a 'wide' ports connecting an host to the A34812-ITX, and cascaded to additional expanders. The A34812-ITX includes a number of enclosure management features that allow system vendors to monitor temperatures, sensors and VPD information as well as control PWM fans for optimal noise management.
