Dell - Dell Linux - RAID & Storage
Dell and Linux: where low-cost and standards-based hardware meets low-cost and standards-based solutions. The new PERC 5 and PERC 6 RAID controllers use SAS (Serial Attached SCSI), and a new driver, megaraid_sas. The new SAS 5 and SAS 6 non-RAID controllers use a new driver, mptsas, part of the mptfusion driver family. Both drivers are included in kernel.org 2.6.x kernels, and have been backported

The former is a (some would say bloated) Java-based GUI managing and mon
