A42412-ENC Secure JBOD

 The Astek A42412-ENC Secure JBOD has state of the art Gen3 Serial Attached SCSI (SAS) expanders that work with either SAS (Up to 12Gbps) or SATA (up to 6Gbps) SSDs (Solid State Drives) and HDDs (Hard Disk Drives). The compact JBOD can hold twenty-four 2.5” SATA or SAS drives ranging in thickness from 6 to 14.5mm.

The A42412-ENC is a very flexible JBOD that can be configured with either one SAS Expander (Single Controller Configuration) or two SAS Expanders (Dual Controller Configuration). The dual controller configuration allows testing of a High Availability (HA) architecture with dual ported SAS drives. A key feature of the JBOD is the ability to change the data path configuration by simply reconnecting the internal SAS cables, or, by using "Hard" zoning via firmware. The Crypto Key Erase/Block Erase option uses SED drives to secure sensitive data in potentially hostile environments. The Key Erase/Block Erase sequence can be activated through a front panel push button or through scripted CLI commands. 

Each Gen3 SAS Expander controller board can provide up to 28GBytes/sec of data bandwidth through six Mini-SAS HD external x4 connectors (SFF-8644). The six external MiniSAS HD ports on each SAS Controller board can be configured as a single x4, dual x8, or as a quad x16 wide port. A single x4 port can provide 4.8GB/sec of data bandwidth to a single server whereas a quad x16 wide port can deliver up to 19GB/sec of data bandwidth. In addition, each x4 port connector can support both passive copper cables (up to 3M in length) or Active Optical Cables (AOCs up to 100M in length). A typical configuration is using six standard Mini-SAS HD (SFF-8644) Gen3 SAS Cables connected to six different servers
