RTSASR-12X RANCHO 12 PORT 3GB SAS EXPANDER Description -------------------------------------------------------------------------------- RTSASR-12X is a 12-port, 3 Gigabit Serial Attached SCSI Expander (SAS Edge Expander) in a 1U rackmount chassis. This SAS expander provides functionality for connecting targets and initiators with up to 12 phys integrated for SAS initiator, SAS target, SAS expander, or Serial ATA (SATA) target devices. The RTSASR-12X supports both wide and narrow port configurations. Features -------------------------------------------------------------------------------- Supports SSF, STP, and SMP standards Supports SATA Supports multiple data rates and auto negotiation for SAS and SATA (SATA-1.5Gb/s and SAS-3.0Gb/s) Provide low latency connection router Provide configurable drive spin up sequencing on per phy basis LED Indicators for Act/Fault Allows conncurrent connections for SAS and SATA targets Programmable a scalable interface for managing general purpose data communication Allows Addressing of multiple SATA targets Allows multiple initiators to address a single target Decode SMP packets that are distined for the expander Performs CRC checking and generation on the request frames and response frames UART interface for debug function Applications -------------------------------------------------------------------------------- The RTSASR-12X can be used in simple topologies to attach an initiator to SAS/SATA devices, in edge expander topologies to increase the number of accessible devices, or in fault tolerant path redundancy topologies to improve system reliability. Up to 144 devices can be connected by cascading multiple RTSASR-12X expanders. 1U rack mount servers Storage subsystem: RAID, JBOD |
