The EqualLogic PS4000 family provides a wide selection of entry level storage systems and virtualized SANS with multiple drive combinations ranging from SATA/SAS drives for archival use, to high performance SAS drives for heavy workloads to a hybrid mix for multiple applications. Drive support varies between 12-drive to 24-drive support. The PS4100 series connects to a PS4100 of the same family or to another PS6100 in the parallel series.
