JetStor SAS 824J4 is a 24 bay 4U rackmount JBOD unit. The 12Gb SAS JBOD accommodates optional dual controllers, the latest SAS 3.0 12Gb/s interface which boosts the throughput up to 4,800MB/s per host. Based on this powerful performance, the JetStor SAS 824J4 12Gb SAS JBOD can efficiently meet demands for Windows Server 2012/2016 projects

The JetStor SAS 824J4 incorporates the latest enhancements in SAS along with LSI Databolt bandwidth optimizer technology (EDFB, End Device Frame Buffering).
