The ETERNUS JX40 is a reliable and innovative easy-to-use storage subsystem. As Direct Attached Storage (DAS), it extends the storage-capacity of Fujitsus PRIMERGY servers through a fastest 6 Gbit/s SAS connection by up to 144 Terabyte. With a height of only two units per shelf, the ETERNUS JX40 subsystem meets the requirements for a compact design with 2.5 inch mixable SAS and SATA hard disk drives in 19-inch rack infrastructures.   Quality and realiabitlity Direct Attached Storage (DAS) for intel-based servers with fastest 6 Gbit/s SAS connection. Up to 144 high performance SAS and/or large capacity SATA disk drives enlarge storage capacity by up to 144 Terabyte. Innovation and flexibility Components like hot plug disk drives and power supply modules can be replaced while the server is running. Standardized 2.5 PRIMERGY server disk drives are used. Ease of use Status of the components is signalized by LED displays and light-emitting diodes. Drive extension is completely managed by the server and can be used in all usage scenarios with certified PRIMERGY servers. The subsystem can be integrated in the standard Fujitsu server management ServerView Suite.
