ESDS S48F-G2842

ESDS S48F-G2842 (Legacy product)

The ESDS S48F-G2842 is a high-density, 48-bay storage system. With hybrid connectivity including Fibre Channel (FC) and iSCSI ports, the single-controller ESDS S48F-G2842 enables SMBs to deploy high-availability FC SANs delivering outstanding price-performance and achieve highly cost-effective remote replication with iSCSI ports. The large storage capacities of the ESDS S48F-G2842 are ideal for applications such as data archiving and HPC.

Please refer to the EonStor DS S48F-R/G2842 datasheet.

Features Benefits
